Food enterprises inspect their own products, which is generally called enterprise self-inspection. Self-inspection can be carried out from the food enterprise's raw materials, auxiliary materials, additives, etc., whether the claim is complete, whether the use is legal and standardized, etc. If you want to check whether the quality of your products meets the requirements, there are two kinds, one is the factory inspection, that is, the inspection of the product before leaving the factory.

A kind of special inspection, that is, surprise, special inspection. Often, certain aspects are examined in a focused manner.

The regulatory department inspects the enterprise and conducts sampling inspection on the product, which is called supervision and spot check. It is also divided into many kinds, from the level of view, there are national supervision and spot checks, provincial regular supervision and spot checks, city and county level supervision and spot checks. In terms of content and function, there are regular supervision and spot checks, special supervision and spot checks, law enforcement spot checks, complaint quality appraisal spot checks, etc.
