Introduction
Standard Overview and Technical Background
LS/T 3124-2019 was proposed by the National Technical Committee for Standardization of Cereals and Oils (SAC/TC 270), which stipulates the quality requirements, inspection methods, packaging, storage and transportation specifications of Suaea salsa seeds. This standard replaces the original agricultural industry standard. The main technical changes include:
- Added the grading indicator of oil content (≥12.0% is excellent)
- Refined the detection method of foreign impurities
- Updated the moisture determination to cite the latest version of GB 5009.3
Analysis of core quality indicators
| Indicator items | Excellent grade | Qualified grade | Detection method |
|---|---|---|---|
| Oil content | ≥12.0% | ＜12.0% | GB/T 14488.1 |
| Water content | ≤10.0% | GB 5009.3 | |
| Total impurities | ≤5.0% | ≤8.0% | GB/T 5494 |
Explanation of key test methods
4.2.1 Determination of oil content
Use Soxhlet extraction method (GB/T 14488.1), please note:
- The sample crushing particle size should pass through the 1mm sieve
- The ether extraction time is not less than 8 hours
- Parallel determination tolerance ≤ 0.5%
4.2.2 Impurity Analysis
When implementing according to GB/T 5494, it is necessary to distinguish:
- Inorganic impurities (sand, soil)
- Organic impurities (other plant seeds)
- Sieves with specified apertures should be used for processing undersize
Implementation and application suggestions
Main points for packaging, storage and transportation
According to the requirements of Chapter 9 of the standard:
- The packaging materials shall comply with the provisions of GB/T 8946. It is recommended to use double-layer moisture-proof woven bags
- The relative humidity of the storage warehouse shall be controlled below 65%
- The transportation vehicles shall be equipped with rain and moisture-proof facilities
Enterprise implementation path
It is recommended to implement it in three stages:
| Preparation stage | Laboratory method validation (30 days) |
| Transition stage | Parallel testing of new and old standards (60 days) |
| Full implementation | Establish a quality control manual |
