Overview of Avocado and Its Industrial Significance
Avocado (Persea americana) is a tropical and subtropical fruit with immense nutritional and economic value. As of recent years, Mexico leads global avocado production with 5.6 million tonnes annually, contributing to over 34% of global supply. While China is emerging as a major grower—especially in Yunnan, Guangdong, Fujian, and Hainan—the lack of a food processing plant infrastructure limits value addition.
To minimize post-harvest losses and improve food manufacturing efficiency, it is essential to invest in avocado oil extraction plants—especially as overcapacity in fresh produce looms large.
Avocado Oil Extraction Methods
Mechanical Extraction Process
The cold-pressed avocado oil process closely resembles olive oil production, with added steps:
- De-skinning and de-seeding of ripe avocados
- Grinding the pulp into a paste
- Malaxation at 45–50°C for 40–60 minutes
- Centrifugal separation to isolate oil, water, and solids
- Final polishing centrifuges for oil clarity
This cold-pressed technique ensures high-quality avocado oil with low Free Fatty Acid (FFA <0.5%) and Peroxide Value (PV <4 meq/kg), meeting international standards for extra virgin oil.
Alternative Extraction Technologies
Advanced methods used in food technology consulting include:
- Supercritical CO₂ extraction
- Aqueous enzymatic extraction
- Ultrasonic-assisted and microwave-assisted extraction
These methods enhance yield and stability without compromising on nutritional integrity, especially when operated under optimized time and temperature settings.
