Pretreatment & Pressure Strategies for Oil Pressing‌

During the oil extraction process with a hydraulic oil press, precise pressure regulation significantly impacts both the yield and quality of the oil. The optimal pressure required for different oilseed crops (such as rapeseed, peanuts, soybeans, etc.) varies during the extraction process. For example, in rapeseed oil extraction, a lower pressure may be needed initially to cause preliminary deformation of the oilseeds, and as the extraction process advances, the pressure should be gradually increased to fully extract the oil.

Improper pressure regulation may lead to a series of problems. Excessive pressure can increase the impurity content in the extracted oil and damage the oil extraction equipment, shortening the lifespan of the equipment; conversely, insufficient pressure may fail to fully extract the oil, reducing the oil yield and causing waste of raw materials.

Customizable pressure control & process optimization

SIMEC oil press machine is equipped with an advanced pressure control system that can automatically adjust the pressure based on the set parameters and real-time monitored data. The system includes components such as pressure sensor, controller, and actuator, enabling precise and stable pressure regulation.

In addition to the precision of pressure regulation, SIMEC oil press can also provide customizable pressure and time control schemes. However, the optimal pressure and time control schemes for each type of oilseed, as well as the best pretreatment methods, are not determined by the machine. Instead, users need to conduct repeated experiments, accumulate data, and analyze and summarize the results to figure them out.

Pretreatment & pressure strategies for oil pressing‌
While pressure regulation is a key factor in oil extraction, ‌material pretreatment‌ plays an equally vital role in determining both ‌extraction efficiency‌ and ‌final oil quality‌. Different oil-bearing materials require customized pretreatment workflows, which typically involve:
Dehydration‌ (moisture control)
Size reduction‌ (crushing/grinding)
Thermal processing‌ (steaming/roasting)

Next, let’s analyze the recommended set pressure variation for the following materials: soybean seeds, coriander seeds, almond seeds, nutmeg (jaiphal) seeds, boswellia and senna extract cake.

There is no universal set pressure variation for these materials when using a hydraulic oil press, as it can be affected by multiple factors such as the material characteristics (oil content, hardness, moisture), pretreatment effectiveness, target oil yield vs. quality balance. For most of the raw material, it’s important to start from low pressure, then increase gradually. Now, let’s apply these principles to six target materials, starting with their unique pretreatment needs and corresponding pressing strategies.

1. Soybean Seeds

Raw Material Pretreatment
Cleaning	Remove foreign materials (stones, dirt, broken seeds) using a sieve or air classifier.
Drying	Reduce moisture content to 8-10% via air-drying or low-temperature drying (40-50°C) to prevent mold and improve oil yield.
Crushing	Use a roller mill or hammer mill to break seeds into coarse particles (3-5mm) to expose oil cells.
Conditioning (Optional)	Steam for 10-15 minutes at 80-90°C to soften cell walls and enhance oil flow during pressing.
Pressing Parameters & Operation
Pressure Setting	Start at 30 MPa, gradually increasing to 40-45 MPa (long-term safe range) to avoid over-stressing the press.
Pressing Time	2-3 minutes for steady compression, allowing gradual oil release.
Retention Time	5-8 minutes to ensure full oil drainage; longer retention helps extract residual oil from dense soybean cakes.

2. Coriander Seeds

Raw Material Pretreatment
Cleaning & Sorting	Use a vibrating sieve to remove debris and undersized seeds.
Moisture Adjustment	If moisture >12%, dry at 35-40°C until moisture is 8-10%.
Cracking	Gently crush seeds with a roller mill to split them into halves (avoid excessive powder to prevent clogging).
Roasting (Optional)	Roast at 100-110°C for 15-20 minutes to enhance oil flavor and release oils more easily.
Pressing Parameters & Operation
Pressure Setting	Maintain 35-40 MPa to handle small, brittle seeds without generating excessive fines.
Pressing Time	1.5-2 minutes for quick compression, suitable for small seeds.
Retention Time	4-6 minutes to allow oil to flow through the compacted seed bed.

3. Almond Seeds

Raw Material Pretreatment
Shell Removal	Mechanically remove hard shells; use a nutcracker for uniform splitting.
Blanching (Optional)	Soak in hot water (80°C) for 1-2 minutes to remove skins, improving oil clarity.
Drying	Ensure moisture <8% (air-dry or low-temperature drying at 40°C).
Chopping	Cut almonds into 4-5mm pieces to increase surface area for oil extraction.
Pressing Parameters & Operation
Pressure Setting	Start at 25 MPa, gradually increasing to 35-40 MPa (almonds have high oil content; lower pressure prevents excessive cake fines).
Pressing Time	2-2.5 minutes for gentle compression.
Retention Time	6-8 minutes to allow slow drainage of viscous almond oil.

4. Nutmeg (Jaiphal) Seeds

Raw Material Pretreatment
Shell Removal	Crack hard outer shells using a specialized nutcracker; discard shells.
Grinding	Use a disc mill to grind kernels into a coarse powder (2-3mm particles) to break oil-rich tissues.
Conditioning	Warm at 60-70°C for 10 minutes to soften oils (nutmeg oil has a low melting point, ~30°C).
Pressing Parameters & Operation
Pressure Setting	40-45 MPa to handle the dense structure of nutmeg kernels.
Pressing Time	2.5-3 minutes for steady compression of granular material.
Retention Time	5-7 minutes to ensure full extraction of aromatic nutmeg oil.

Boswellia/senna extract cakes are byproducts with residual oils, not primary oilseeds. Pretreatment focuses on moisture reduction and structure modification for oil recovery.

5. Boswellia Extract Cake

Raw Material Pretreatment
Dehydration	Reduce high moisture (75% → <15%) via forced-air drying at 50-60°C for 4-6 hours to prevent bacterial growth and improve press efficiency.
Crushing	Break cake into 1-2cm chunks using a jaw crusher; grind into a coarse meal to expose residual oil pockets.
Mixing (Optional)	Blend with dry rice hulls (10% by weight) to create a porous structure for better oil flow.
Pressing Parameters & Operation
Pressure Setting	The pressure needs to be gradually increased to 45-50 MPa (high pressure needed to extract residual oils from compacted cake).
Pressing Time	3-4 minutes for slow, firm compression.
Retention Time	8-10 minutes to allow oil to drain through the dense, moisture-reduced cake.

6. Senna Extract Cake

Raw Material Pretreatment
Drying	Reduce moisture from 75% to 12-15% using a tray dryer at 50°C (6-8 hours) to improve pressability.
Shredding	Use a hammer mill to shred cake into fine strips (5-10mm) to increase surface area.
Conditioning	Mix with 5% calcium oxide to absorb excess moisture and prevent cake sticking during pressing.
Pressing Parameters & Operation
Pressure Setting	Gradually increase to 45-50 MPa (similar to Boswellia cake).
Pressing Time	3-4 minutes for gradual compression.
Retention Time	8-10 minutes to maximize oil extraction from the low-oil cake.

In actual operation, it is necessary to conduct preliminary tests according to the specific characteristics of the raw materials, equipment performance, and the desired product quality to determine the most suitable set pressure variation range, pressing time and retention time.

Avocado Oil Extraction Machine to Kenya

Tags : Avocado Oil Extraction Machine Kenya

Kenya is Africa’s largest avocado producer, with main varieties including Hass, Fuerte, Jumbo, Pinkerton, and Reed. The primary harvest season runs from March to July, while a shorter secondary harvest occurs around October. In 2023, Kenya’s avocado production reached approximately 417,000 metric tons.

Fuerte, one of the major cultivated varieties in Kenya, features larger fruit with soft flesh and high oil content (typically 20%-30%), making it ideal for oil extraction. The oil derived from Fuerte avocados has a mild, delicate flavor without strong pungent odors, suitable for various cooking methods and food processing applications, enhancing dishes with its unique taste.

Hass avocado serves as Kenya’s primary export variety. It also boasts high oil content and excellent oil quality, rich in healthy fatty acids and vitamins, making it well-suited for both oil production and culinary uses.

In Kenya, there are already a number of avocado oil manufacturers, many of which adopt SIMEC cold pressing technology. The avocado oil extraction machine provides 380 tons of vertical force pressing on oil material to extract oil efficiently. Throughout the cold pressing process, no external heat is applied to the oil material, and vertical pressing will not generate friction heat, preventing any temperature increase. Cold pressed avocado oil retains natural flavor and all the beneficial nutrients, thus it is called Extra Virgin avocado oil. The avocado oil price in retail market reaches $30 per liter.

In January 2025, SIMEC delivered avocado pasting machine and avocado oil extraction machine to Nyeri, Kenya. The ocean freight to Kenya, import customs clearance, and door-to-door delivery to the customer’s premises are fully handled by SIMEC.

This avocado oil manufacturer uses avocado pasting machine to peel and pit the whole fruits, and at the same time beat the flesh into paste form. All the three functions peeling, pitting and beating are integrated into one machine. To maximize the efficiency of avocado oil extraction, the avocado paste will be dehydrated using a low temperature vacuum dehydrator. The low-temperature and vacuum environment can ensure that the avocados will not be oxidized during the dehydration process, and retain the nutrients to the greatest extent possible. After that, the dehydrated avocados will be fed into the oil press machine to produce extra virgin avocado oil.

Utilizing SIMEC avocado oil processing machine, this Kenyan customer can expect an investment payback period of no more than six months.

Avocado Vacuum Dehydrator

Tags : Avocado Vacuum Dehydrator Low-Temperature Rapid-Dehydration

Engineered to address avocados’ dual challenges of nutrient richness and heat-sensitive oxidation, the SIMEC Avocado Vacuum Dehydrator employs revolutionary Low-Temperature Rapid-Dehydration (LTRD™) technology to lock in 98%+ of nutrients, even at 1/3 the time of conventional drying methods.

Technology introduction:
Low-Temperature Avocado Vacuum Dehydrator consists of biomass heating system, heat flow circulation system, vacuum chamber, material tray support, control system and other necessary accessories.

The biomass heating system runs on biomass pellets or macadamia nut shells. It automatically controls heat flow temperature within a set range. With automatic feeding and temperature control, it cuts heating costs. Plus, it shrinks the carbon footprint during avocado dehydration.

The vacuum chamber, made of food-grade stainless steel, is a sealed space for drying. In vacuum, the boiling point of water drops, enabling low-temperature dehydration and preventing oxidation. The tray support with heat-flow pipes evenly heats the vacuum chamber. Well-designed and strong, it can hold 96 trays, greatly increasing throughput.

The control system is equipped with advanced sensors to monitor both the heat-flow temperature and the chamber temperature in real-time. It then automatically and precisely adjusts the heater output, ensuring that the chamber temperature remains stable within a pre-set range.

Technical advantages:
1. Low Temperature Dehydration Retains Nutrients.
Under the vacuum condition, the boiling point of water drops significantly, enabling the moisture within the avocados to swiftly vaporize even at a very low temperature, thereby achieving efficient dehydration. This process maximally preserves the original nutritional value of the avocados.

2. Vacuum Environment Prevents Oxidation.
Oxidation darkens avocados, spoils their flavor, and deactivates nutrients like antioxidants. In a vacuum environment, the minuscule oxygen content effectively stops avocados from oxidizing. Extra Virgin avocado oil can be extracted from vacuum-dehydrated avocado pulp using an avocado oil cold press machine.

3. Circulating Heat Flow Ensures Uniform Dehydration.
The circulating heat flow system is distributed throughout the vacuum chamber, forming an all-round heating structure to ensure uniform temperature. Avocados in the upper, middle, and lower layers of the vacuum chamber can all be dehydrated in the same temperature and pressure environment, which ensures that each piece of dried avocado has consistent color, taste, and water content. Avocados can be dehydrated efficiently at low temperature.

4. Eco-Friendly Process.
It’s a low energy consumption, low carbon footprint process for dehydrating avocados.

5. Large-Capacity Design.

Cold-Pressed Sunflower Seed Oil

Tags : Cold-pressing Technology Sunflower Oil

Sunflower seed oil has become a part of human food culture with its unique nutritional composition and health value. As a cooking oil, sunflower oil is rich in nutrients and has many benefits for human health.

Sunflower oil is rich in unsaturated fatty acids, especially linoleic acid and oleic acid, which play a positive role in maintaining cardiovascular health and lowering cholesterol levels. In addition, sunflower seed oil also contains antioxidants such as vitamin E and phytosterols, which help resist free radical damage and protect cells from oxidative stress, thereby delaying the aging process and promoting overall health. In the field of nutrition, sunflower oil is recognized as a healthful cooking oil because of its balanced fatty acid ratio and rich nutrients.

In the processing of sunflower seed oil, cold pressing is a highly respected method, especially hydraulic cold pressing technology. A vertical press force of 380 tons exerted on sunflower seeds effectively ensures the high efficiency of the oil extraction process. Notably, throughout the entire oil extraction procedure, no external heat is applied to sunflower seeds, and vertical pressing will not generate friction heat, preventing any temperature increase.

Hydraulic cold-pressing technology maximizes nutrient and flavor retention. By keeping the temperature below 50°C, it prevents high-heat oxidation, minimizing nutrient loss. It also preserves the oil’s fresh aroma and natural color. As a result, the sunflower seed oil processed by hydraulic cold-pressing exhibits a clear, light-golden hue and a pure, delicate taste. Evidently, compared with conventionally processed oils, cold-pressed sunflower oil is far superior in both taste and nutritional value

Sunflower seed oil can be presented to consumers in the purest and healthiest state through the hydraulic cold pressing technology. In the European market, retail prices for cold-pressed sunflower oil generally range between €20–30 per liter, while premium organic brands may exceed €30 per liter.

About Canola Oil

Tags : Canola Oil Cold Pressing Technology

Canola is a crop with plants from three to five feet tall that produce pods from which seeds are harvested and crushed to create canola oil and meal. These plants also produce small, yellow flowers, which beautify the environment.

Canola seeds contain approximately 45 percent oil, a high percentage packed into seeds similar in size to rapeseed but distinguished by their brownish-black hue. Although they look similar, canola and rapeseed plants and oils are very different. Canadian scientists used traditional plant breeding in the 1960s to practically eliminate two undesirable components of rapeseed, erucic acid from oil and glucosinolates from meal, to create “canola,” a contraction of “Canadian” and “ola.” Canola oil is prized for its heart-healthy properties with the least saturated fat of all common culinary oils.

Canola belongs to the Brassica plant family, which also includes mustard, broccoli, Brussels sprouts, and cauliflower. Besides China, canola is cultivated in Canada, Australia, Europe, and the United States. Canola seed is also known as “double low rapeseed” due to its low levels of erucic acid and glucosinolates, particularly in China and Europe. Canola plants are easy to grow, need fewer pesticides, and the oil extraction process is efficient with little waste.

Production: Canola plants are grown in suitable fields, harvested, and seeds are transported to processing facilities. After cleaning and moisture adjustment, canola seeds are pressed to release the canola oil. Following extraction, the canola oil can be further refined to produce a shelf-stable, clear and neutral-tasting oil which can be stored at room temperature for about one year. The remaining solid parts of canola seed can be processed into canola meal, a protein-packed product used in animal feed.

Health Benefits: Canola oil has a beneficial fatty acid profile. It’s low in saturated fat, reducing the risk of heart disease. It’s rich in monounsaturated fats like oleic acid, and polyunsaturated fats including omega – 3s, which support brain health and reduce inflammation.

Culinary Versatility: Its neutral flavor and high smoke point (about 400°F/204°C) make it suitable for frying, sautéing, baking, and salad dressings. It doesn’t overpower other ingredients and can withstand high-heat cooking without breaking down.

Advantages of Cold-pressed Canola Oil
1. Nutrient Retention: cold-pressed extraction, without heat or chemicals, preserves more vitamin E and omega-3s, which are good for skin and immune system. Zero trans fats, more omega 6 & 3 than olive oil. High in vitamin E, low in saturated fat.
2. Pure and Natural Flavor: it has a fresh, delicate taste, ideal for salad dressings and raw food recipes, free from off-flavors of refined oils.
3. Minimal Processing: involving only mechanical pressure, it’s more environmentally friendly and less likely to introduce contaminants.

In summary, canola oil, especially cold-pressed, is a healthy, versatile, and sustainable cooking choice, appealing to health-conscious consumers and chefs.
Advanced cold pressing technology can maximize the value of canola oil.

Brief Discussion on Oil Press Machine

Tags : Oil Press Oil Press Machine

Oil press machine, as a device for extracting vegetable oil from plant raw materials, is important in the modern oil industry. SIMEC will conduct a popular science discussion on the functionality of oil press, aiming to briefly introduce its working principle, classification and application.

Application of oil press machine
Oil press machines are widely used in pressing various oil crops, such as soybeans, peanuts, cottonseeds, rapeseeds, and sesame seeds, etc. Through advanced technology and design, they achieve efficient pressing, improving oil yield. Equipped with automatic control systems, they ensure the stability and safety of the pressing process, while emphasizing energy conservation and environmental protection. These machines utilize low energy consumption and exhibit high efficiency.

Oil press machines can also equip the functions of impurity removal, refining, filtration, etc., to achieve integrated production and improve production efficiency and product quality.

Classification of oil press machine
Oil pressing machines can be divided into many types according to their structure and pressing methods. Common ones include screw oil press machine, hydraulic oil press machine, etc. These different types of oil pressing machines have their own characteristics in pressing efficiency, oil yield, application scope, etc., and can meet the pressing needs of different oil crops.

Screw oil press machine works by physically pressing pre-treated oil material. The material enters the pressing chamber via a hopper, where a rotating screw pushes it. The resulting high pressure generates friction, causing movement and heat. The screw’s design, with a gradually increasing diameter and decreasing pitch, enhances pressing efficiency and thermally denatures proteins, facilitating oil precipitation.

Hydraulic oil press machine adopts cold processing technology to extract oil. It provides 200-380 tons of vertical pressing force on oil material, but will not generate friction and heat. The oil material will not be heated, no temperature rise during oil extraction process, hence no protein denaturing, no nutrients loss. The continuous high pressure is generated by hydraulic station, controlled in automatic mode. The electricity consumption of oil extraction process is much lower than screw oil press.

Methods for Dehydrating Avocado

Tags : Avocado dehydrator Avocado Dryer

For avocado enthusiasts seeking to create a portable and healthier snack, the following four dehydration methods provide solutions.

Food Dehydrator Method
The most common and well-known way to dehydrate avocados is to use a dehydrator. This is the quickest and most efficient dehydration process, taking only a few hours.

To dehydrate avocados using a traditional dehydrator, you can follow these steps:
1. Take your room-temperature avocado and cut it into thin slices, about 3mm thick.
2. Place the slices in a single layer on a dehydrator tray.
3. Set the dehydrator temperature to 57℃ and let it run until the avocado slices are dehydrated, which can take anywhere from 8 to 12 hours, depending on the dehydrator and the thickness of the slices.
4. Check the slices every few hours to see if they are dry, and rotate the trays.
5. Once they are dry and leathery, with an apperance similar to fruit leather, remove the slices from the dehydrator and allow them to cool completely.
6. Store the dehydrated avocado slices in an airtight container or resealable plastic bag in a cool, dark place.

Setting of Dehydrator Temperature in Commercial Applications: When dehydration begins upon the introduction of food, the ongoing evaporation of moisture from the food extracts heat, causing the actual temperature within the chamber to be approximately 20 degrees Fahrenheit lower than the set temperature. This phenomenon is considered normal. As the moisture content in the food decreases, the temperature within the chamber gradually rises to approach the predetermined set value.

Air Drying Method
Air drying avocados is one of the simplest methods for dehydrating avocados. This method works best in a dry and warm environment. It is helpful to lay the avocados on a drying rack or dehydrating screen to ensure proper air circulation and even drying.

To air-dry avocados, follow these steps:
1. Cut the avocado in half and remove the pit.
2. Place the avocado halves cut-side up on a paper towel to absorb excess moisture.
3. Leave the avocados to air-dry in a warm, dry place for a few days or until the cut surfaces have become firm and slightly wrinkled.
4. Store the air-dried avocados in an airtight container until ready to use.

You should note that air-drying avocados can help prolong their shelf life, but it won’t prevent them from eventually going bad. You should still use or freeze them within a few days.

Oven Drying Method
Oven drying is a method of dehydrating used to extend the shelf-life of food for people interested in long-term food preservation. Many people who do not have or want to purchase a traditional dehydrator choose to use this method of dehydrating their food.

To oven-dry avocados, follow these steps:
1. Preheat the oven to 93℃, or the lowest temperature your oven allows.
2. Cut the avocado into thin slices, approximately 3mm thick.
3. Place the slices on a baking sheet lined with parchment paper or a silicone baking mat.
4. Bake the slices in the oven for 4 to 6 hours, or until they are dry and slightly leathery in texture.
5. Check the slices every hour and rotate the baking sheet if necessary to ensure even drying.
6. Once they are dry, remove the slices from the oven and let them cool until they reach a crispy texture.
7. Store the oven-dried avocado slices in an airtight container or resealable plastic bag in a cool, dark place.

When oven-drying avocados, it can be a slower process compared to using a dehydrator. It’s important to keep a close eye on the avocados and monitor them regularly to avoid over-drying, which can cause them to become too brittle and lose their flavor and nutrients.

Sun Drying Method
If you live in a sunny and warm climate, you can use the sun to dry your avocado slices. This method takes the longest, but it’s also the most natural and eco-friendly way to preserve all the health benefits of avocados.

Sun-drying avocados is a traditional method of preserving food. However, achieving consistent results can be challenging, and it may pose food safety risks if not done correctly.

Here’s how to sun-dry avocados:
1. Cut the avocado into thin slices, approximately 3mm thick.
2. Place the slices on a clean, flat surface that has been covered with a layer of cheesecloth to prevent contamination.
3. Position the surface in a sunny, well-ventilated area where the temperature will remain between 35°C and 46°C for several days.
4. Turn the slices every few hours to ensure even drying and to prevent mold or spoilage.
5. Continue drying the slices until they are dehydrated and slightly leathery. This process could take anywhere from 2 to 5 days, depending on the weather conditions.
6. Store the sun-dried avocado slices in an airtight container or resealable plastic bag in a cool, dark place.

If you choose to sun-dry avocados, remember that it can be a slow and unpredictable process. It’s important to regularly monitor the slices to ensure they are drying properly and to prevent contamination. Using a dehydrator or oven to dry avocados offers a more controlled and consistent drying environment.

Classification Method for Avocado Oil

Tags : Cold Pressed Extra Virgin Avocado Oil Crude Avocado Oil Extra Virgin Avocado Oil Pure Avocado Oil

Avocado oil has become common in kitchens around the world, renowned for its rich health benefits and wide applicability in cooking. On the shelves of supermarkets, different types of avocado oil attract the attention of consumers with their diverse packaging and labels, such as “extra virgin avocado oil”, “virgin avocado oil” and “pure avocado oil” and other names frequently appear. If you purchase avocado oil in bulk, you may come across a producer offering significant differences in price regarding “extra virgin avocado oil” versus “crude avocado oil”. What are the core differences between them? Let’s take a deep dive into the world of avocado oil and learn the difference between regular avocado oil and extra virgin avocado oil.

Since avocado oil lacks universally defined quality parameters, people usually use the recommended values for olive oil as a reference. The quality standards for olive oil can be found in the Codex Alimentarius and the International Olive Council’s regulations.

Actually, a classification method for avocado oil can be developed based on its extraction method and fruit quality.

Avocado Oil Classification: Extra virgin avocado oil
Definition Method: Avocado oil of a higher quality, “extra virgin”, corresponds to that produced from high-quality fruit, extracted only with mechanical methods, using a temperature below 50 °C and without the use of chemical solvents.

Avocado Oil Classification: Virgin avocado oil
Definition Method: “Virgin” avocado oil is produced with fruit of a lower quality (with small areas of rot and physical alterations), extracted by mechanical methods, using a temperature below 50 ° C and without the use of chemical solvents.

Avocado Oil Classification: Pure avocado oil
Definition Method: “Pure” avocado oil is a type of oil for the production of which the quality of the fruit is not important; it is a bleached and deodorized oil, infused with the natural flavor of herbs or fruits. “Pure” edible avocado oil is a product with at least 98.5% refined avocado oil.

Avocado Oil Classification: Mixed avocado oil
Definition Method: “Mixed” avocado oil is combined with olive, macadamia, and other oils. Therefore, it presents sensory and chemical characteristics that are variable.

Avocado Oil Classification: Crude avocado oil
Definition Method: The “crude oil of avocado” is a slightly amber-colored fatty liquid, obtained by physical extraction of the avocado pulp and the seed of the avocado fruits.

In actual trade activities, avocado oil can be classified according to different levels of free fatty acid content. (% m/m expressed in oleic acid)

Extra virgin avocado oil ≤ 0.8
Virgin avocado oil ≤ 2
Ordinary virgin avocado oil ≤ 3.3
Pure avocado oil ≤ 1.03
Refined avocado oil ≤ 0.3
Crude avocado oil: no limit

It is imperative to discuss the extraction methods of avocado oil: refining and physical pressing. Refined avocado oil is commonly refined, involving processes like filtering and deodorization, resulting in a neutral- flavored oil with a higher smoke point. Extra virgin avocado oil undergoes physical pressing, a cold processing technique that preserves the fruit’s natural flavors and nutrients by pressing the avocado oil at low temperatures. This gentle extraction method yields an oil with a distinct flavor profile and lower smoke point.

As a technology and equipment supplier, SIMEC focus on the extraction method of extra virgin avocado oil. Adopting SIMEC physical pressing method, there’s no heating for the avocado pulp and no temperature rise during the cold extraction process of avocado oil. The quality of avocado oil can achieve the procurement standard in cosmetic and food industries.
