Long-term stability test of lutein
1. Test Program
(1) Storage and packaging of samples
Considering the storage and use process of wholesale lutein products, the samples used for stability test were also packaged in the same scale production batch.
The packaging and storage placement conditions are the same, i.e. room temperature, protected from light, vacuum double packaging.

Storage location	Storage packaging
Intermediate product storage room	Simulation of production packaging, that i,s the inner bag for plastic vacuum packaging bags, the outer packaging for aluminum foil bags.

 

(2) Selection of test batches
The stability test selects three batches of 5% wholesale lutein samples, and the batches of samples taken are wholesale lutein sample of scale production.
(3)Test frequency
Each batch was sampled 7 times, the time was 0 months, 3 months, 6 months, 9 months, 12 months, 18 months, 24 months.
(4)Test items
According to the standard and characteristics of lutein, the items tested in this test are appearance, content and dry weight loss. These indices
These indicators may change during the storage of lutein, which may affect the quality and effectiveness.

2. Sampling of test samples
The stability test Wholesale Lutein products are produced by the Lutein workshop, after testing and qualified storage, according to the sampling standards
The stability test samples are taken according to the sample sampling standards, and the results are registered and saved after testing and analysis, which is used as the basis for stability data evaluation.
The results were registered and stored as the basis for stability data evaluation.

 

3. Stability data evaluation and conclusion
The expiration date and storage conditions of the product are judged based on the appearance, content and drying loss of the product. The test data are presented in.

The data of this test are given in the form of tables and graphs, so that the stability of luteolin can be evaluated effectively.

 

4. Long-term stability experiments conclusion
Through the long-term stability experiments of three batches of luteolin products, it can be seen from the above experimental data that after 24 months After 24 months of observation and testing, there is no change in the appearance of the product, the highest degradation rate is 1.92%, and the change in dry weight loss is not significant, which meets the requirements. The product wholesale lutein meets the requirements. It can be determined that the product has good stability for 24 months under the above storage conditions.
