Introduction
Analysis of the core content of the standard
| Comparison dimensions | Crude edible rubber seed oil | Finished edible rubber seed oil |
|---|---|---|
| Acid value limit (mg/g) | Not specified | First grade ≤1.0, second grade ≤3.0 |
| Water and volatile matter (%) | ≤0.50 | ≤0.20 |
| Transparency requirements | Not specified | First grade is transparent, second grade allows slight turbidity |
Detailed explanation of key technical indicators
The standard stipulates the refractive index (1.467-1.472) and relative density (0.919-0.926) range of edible rubber seed oil, and its notable characteristics are:
- High unsaturated fatty acid content: linoleic acid (C18:2) accounts for 33.6-42.9%, linolenic acid (C18:3) 14.0-25.0%
- Special saponification value: 175-197mg KOH/g, reflecting the small average molecular weight of triglycerides
- Iodine value 120-145g/100g, indicating medium oxidative stability
Implementation and application suggestions
Manufacturers should pay special attention to the following:
- The refining process needs to control the deacidification process to ensure that the acid value meets the standard
- Use nitrogen protection for storage to prevent oxidation of polyunsaturated fatty acids
- Retail terminals are prohibited from unpacking and selling in bulk, and pre-packaging should comply with the requirements of GB 7718
Background of standard evolution
This standard was jointly formulated by the Hainan Provincial Cereals and Oils Science Research Institute, filling the gap in the standardization of rubber seed oil as a new type of edible oil. Compared with traditional vegetable oils:
| Characteristics | Rubber seed oil | Soybean oil |
|---|---|---|
| Linolenic acid content | 14-25% | 5-9% |
| Saponification value (mg/g) | 175-197 | 189-195 |
