According to the National Grain and Oil Standards and the latest research of the Academy of Agricultural Sciences (2024), high-quality oil-pressing peanuts should meet the following conditions:
| Indicator category | Premium standards | inferior features |
|---|---|---|
| Oil content | ≥48% | <42% |
| protein content | 24-28% | <20% |
| Acid value (mg/g) | ≤1.5 | >3.0 |
| Aflatoxins | Not detected | ≥20μg/kg |
3. Comparison of oil extraction of mainstream peanut varieties
Agronomic experts recommend the following 5 special varieties for oil extraction:
| Variety name | Oil yield | Oleic acid content | planting area |
|---|---|---|---|
| Luhua No. 11 | 51.3% | 78.6% | North China Plain |
| Zhonghua No. 16 | 49.8% | 75.2% | Yangtze River Basin |
| Guangdong Oil No. 7 | 48.5% | 72.9% | South China |
| Jihua No. 4 | 50.1% | 76.8% | Northeastern region |
4. Recommendations for scientific oil extraction methods
The latest guidelines for household oil extraction released by the China Cereals and Oils Society suggest:
1.Preprocessing key:Peanuts need to be dried at 60°C until the moisture content is <8%, which can increase the oil yield by 12%.
2.Temperature control:The cold pressing temperature should be ≤60℃, and the hot pressing temperature should be controlled at 120-130℃.
3.Equipment selection:The screw press produces 5-8% more oil than the hydraulic type, and the oil quality is clearer
5. Analysis of current situation of consumer market
According to e-commerce platform sales data (May 2024):
| product type | Average price (yuan/liter) | monthly sales | Positive rating |
|---|---|---|---|
| Cold pressed peanut oil | 58-75 | 126,000+ | 98.2% |
| Traditional pressed oil | 35-50 | 283,000+ | 95.7% |
| Certified organic oil | 85-120 | 42,000+ | 99.1% |
Conclusion suggestions:Choose high-oleic acid varieties such as Luhua and Zhonghua, use low-temperature pressing technology, and give priority to products with aflatoxin test reports. Self-pressing users need to pay special attention to raw material selection and storage conditions to ensure food safety.
