First, the purpose of retaining samples
The main purpose of retaining samples is to provide effective evidence for tracing the causes of food safety accidents in the consumption process. In addition, it is more convenient to observe the quality changes of products during the shelf life and find possible microbial pollution in the production process.
Second, the sample room environment requirements
The sample storage room should be cool, dry, ventilated, and protected from light, with a thermometer and ventilation and dehumidification facilities. The environment of the sample holding room should simulate the temperature and light of the shop as much as possible, so as to better observe the quality change of the sample holding products.
Third, the regulatory requirements for sample retention.
According to the requirements of national laws and regulations, food production enterprises should keep samples of their products, so as to trace the reasons in time when food safety accidents occur.
Fourth, the sample variety
All materials and products to be tested in production need samples, including products, intermediate products, raw materials, auxiliary materials, packaging materials and temporary samples. Routine sample retention means that when the sample inspection is abnormal and the product is abnormal during storage or sales, each batch of finished products needs routine sample retention for re-inspection.
Food sample retention process:
1, determine the sample retention requirements.
According to product characteristics and regulatory requirements, determine the number and time of samples to be retained.
2. Select the sample container
According to the characteristics of the sample and the requirements of sample preservation, select the appropriate sample preservation container to ensure that the sample will not deteriorate or be damaged during sample preservation.
3. Prepare sample retention labels
Make a sample retention label, indicating the sample name, batch number, production date, sample retention time and other information, and stick it on the sample retention container.
4. Keep the sample.
Save the samples that need to be saved according to the specified quantity and time requirements, and make records.
5. Store samples.
Store the retained samples under specified storage conditions to ensure that the samples will not deteriorate or be damaged.
6, regular inspection
Regularly check whether the appearance, performance and other indicators of the retained samples have changed, and record the inspection results.
7, processing samples
After the expiration of the storage period, properly handle the retained samples to prevent environmental pollution.
