Summer big test! 6 Months Stability Test Report of Function Package under High Temperature and High Humidity
Release time:
May 29,2023
Introduction of test background
The purpose of the stability test is to investigate the law of the nature of the product under the influence of temperature, humidity, light and other conditions over time, and to provide a scientific basis for the determination of the production, packaging, storage, transportation conditions and validity of the product, so as to ensure the safety and effectiveness of the product on the market.
The stability test is divided into three categories: influencing factor test, accelerated test and long-term stability test. The accelerated test and long-term stability test have been carried out this time. The accelerated test has been completed and the long-term stability test is in progress. This report shows the results of the accelerated test.
The accelerated test is carried out under extraordinary conditions, the purpose is to investigate the stability of the product by speeding up the chemical or physical properties of the product in the market. The stability of the product under short-term extraordinary conditions that may be encountered during transportation and preservation is simulated, and the long-term stability of the sample under the specified storage conditions is preliminarily predicted.
The test is carried out under the condition of high temperature and high humidity (40 ℃ ± 2 ℃, RH 75%±5%) for 6 months.
1. Test purpose
To evaluate the stability of Chang An Pig (AAS 01), Chang An Pig (AAP 01) and Mian Jing (AA 01) at 40 ℃ ± 2 ℃ and RH 75%±5% for 6 months.
2. Test design
(1) Evaluation conditions: 40 ℃ ± 2 ℃, RH 75%±5%
(2) Evaluation nodes: initial, January, February, March and June.
(3) Packaging conditions: commercially available aluminum foil bag packaging, labeling, sealing mouth, 1 kg/bag.
(4) Technical indicators: see Table 1.
Note: The maximum selenium content (calculated as Se) in the above three products is 35.0 mg/kg, and the organic selenium content (accounting for total selenium) is ≥ 98%
3. Test materials
(1) Test equipment: constant temperature and humidity box
(2) Test samples: taken from the normal production of finished products in the workshop.
The production date is: Chang 'an Pig AAS01 October 24, 2022, Chang 'an Pig AAP01 October 23, 2022, and Meianjing AA01 October 14, 2022.
4. Detection method
(1) Sensory: visual observation and smell under natural light.
(2) Moisture: in accordance with the provisions of GB/T 6435.
(3) Thiamine nitrate: in accordance with the provisions of GB/T 14700.
(4) Riboflavin: in accordance with the provisions of GB/T 14701.
(5)dl-α-tocopherol acetate: in accordance with GB/T 17812.
(6) Vitamin A acetate: in accordance with the provisions of GB/T 17817.
(7) Iron: in accordance with the provisions of GB/T 13885.
(8) Selenium: in accordance with the provisions of GB/T 13883.
5. Test results
(1) Sensory index
According to Table 2, the three products are sensory stable within 3 months under the conditions of high temperature and high humidity (40 ℃ 2 ℃, RH 75%±5%). At the 6th month, the color is slightly deepened, the smell of fermentation occurs, there is no moldy deterioration and caking, and the sensory change is not obvious.
(2) Test results of technical indicators
According to Table 3 to Table 5, with the extension of the inspection time, the moisture content of the three products gradually increased, and the content of vitamins and mineral elements decreased slightly, but all of them were within the allowable range of the judgment value.
6. Test conclusion
According to the above test results, Chang 'an Pig (AAS 01), Chang 'an Pig (AAP 01) and Meianjing (AA 01) were stored in a high temperature and high humidity (40 ℃ 2 ℃, RH 75%±5%) environment for 6 months under commercially available packaging and sealing conditions. The changes in sensory and technical indexes of the products were within the allowable range of the judgment value and the quality was qualified.
