With the global surge in demand for healthy oils, avocado oil has become a “green gold” for high-end edible oils, nutraceuticals, and cosmetic industries. However, avocado pomace is highly prone to oxidation, has high moisture content, and is heat-sensitive. Traditional extraction methods often result in low oil yield (<70%) and high free fatty acid content, compromising both quality and nutritional value.
QIE Group leverages over 40 years of experience in edible oil engineering to provide low-temperature expansion, vacuum negative-pressure extraction, and precision refining technologies for avocado pomace. This solution maximizes resource utilization while ensuring oil quality, flavor, and nutrient retention for high-end markets.
Producers frequently encounter the following issues using conventional methods:
| Key Metrics | Traditional Process | QIE Custom Solution |
|---|---|---|
| Residual Oil | 5% - 8% | <1% |
| Solvent Loss | > 4.0 kg/t | ≤ 1.5kg/t |
| Vitamin E Retention | 60% - 70% | >92% |
| Product Grade | Crude/Industrial | Premium/ Cosmetic-grade |
Through precise process optimization, QIE Group significantly improves oil yield, quality, and nutrient retention compared to conventional methods.
Unlike traditional high-heat pressing, QIE Group employs low-temperature mechanical expansion to safely release oil and preserve nutrients:
This method improves oil yield by 10%-15% while retaining the natural green color and aroma of avocado oil.
Vacuum negative-pressure extraction is a core advantage for medium-to-large-scale projects:
This technology boosts extraction efficiency while maintaining avocado oil’s natural flavor and nutrients.
After extraction, solvent removal is essential for food safety and compliance:
This process fully meets EU and US FDA food safety standards, allowing the oil to be used in both edible and cosmetic applications.
Refining determines the final quality of avocado oil. QIE Group provides a customized precision refining line:
Removes phospholipids and impurities without chemical additives, improving oil transparency.
Special centrifuge technology separates free fatty acids from avocado oil prone to emulsification, reducing FFA to <0.3 mg KOH/g.
High-efficiency activated clay adsorbs residual impurities while preserving natural green or golden color for cosmetic and edible standards.
For cold climates, controlled cooling separates high-melting waxes, preventing cloudiness in the final oil.
The refined avocado oil is bright, flavorful, and nutritionally stable—ideal for high-end edible oils, nutraceuticals, and cosmetic raw materials.
Steam or vacuum treatment removes off-flavors and trace volatile compounds, ensuring avocado oil has a clean taste, smooth texture, and improved shelf stability.
The refined oil is bright, flavorful, nutritionally rich, and suitable for high-end edible oils, nutraceuticals, and cosmetic raw materials.
QIE Group offers full turnkey solutions from civil design, equipment manufacturing, installation, commissioning, to staff training, ensuring project efficiency.
Advanced PLC automation systems monitor the production line in real-time, reducing human error and improving operational stability.
Equipment meets CE and ISO standards, facilitating smooth entry into high-end international markets.
QIE Group's full-process avocado pomace oil solution is suitable for:
Efficient extraction and refining maximize product value and support global market expansion.
Q1: How does avocado pomace oil extraction differ from conventional pressing?
A: Low-temperature expansion combined with vacuum negative-pressure extraction protects unsaturated fatty acids and chlorophyll, delivering higher yield and lower residual oil.
Q2: How does vacuum negative-pressure extraction prevent oxidation?
A: Low temperature and vacuum reduce oxygen exposure and thermal damage, preserving oil nutrients.
Q3: Is QIE Group's solution compliant for export?
A: Yes. Equipment meets CE/ISO standards, and solvent-free oil complies with EU and FDA regulations.
Q4: How is defatted pomace utilized?
A: It can be converted into high-fiber animal feed, biomass fuel, or organic fertilizer, achieving zero-waste operations.
Extracting and refining avocado pomace oil requires precise temperature control and oxidation protection. Through low-temperature expansion, vacuum negative-pressure extraction, vacuum solvent removal, and five-stage precision refining, QIE Group maximizes nutrient retention, preserves flavor, and enhances oil quality and market competitiveness.
