Do food preservatives require microwave sterilization?

Expound: The importance of food microwave drying sterilization ! Under the condition of using the same amount of preservatives, the more serious the food contamination, the more the original bacteria, the worse the preservative effect. Relevant data show that microbial proliferation process, the beginning is a slow induction period, after the induction period, the rapid convergence into the logarithmic phase, proliferation is very vigorous. Due to the limitation of the role and amount of food additives in the world, it usually only inhibits microorganisms and prolongs the induction period in the process of microbial proliferation.

If food is seriously contaminated by microorganisms, the use of preservatives will not help. For example, when sorbic acid is seriously contaminated by microorganisms in food, sorbic acid becomes the nutrient of microorganisms, which not only can not inhibit the reproduction of microorganisms, but also can accelerate food spoilage. Therefore, when using food preservatives, we should pay attention to keeping good hygienic conditions and reduce the number of original bacteria in food. It is also very important to equip microwave sterilization equipment to sterilize food itself or packaging, and to minimize the possibility and extent of microbial contamination of food.

So preservatives and microwave sterilization are not two choices, but measures to cooperate and help each other.
