The function of potassium sorbate in food

Introduction: potassium sorbate is an additive added to food People don't know much about this additive, so what's the role of potassium sorbate in food? Xiaobian will introduce you in this article Potassium sorbate chemical name 2,4-ethylenepotassium, odorless or odor free, unstable in the air, can be oxidized and colored, hygroscopic, easily soluble in water and ethanol Sorbic acid and potassium sorbate can inhibit the activity of dehydrogenase in the cells of microorganisms, especially molds, and combine with sulfhydryl group in the enzyme system, so as to destroy many important enzyme systems and achieve the purpose of bacteriostasis and antisepsis When the pH value is lower than 5-6, the bacteriostatic effect is the best It has no bacteriostatic effect in the food seriously polluted by microorganism Potassium sorbate is an unsaturated fatty acid salt that can be assimilated into carbon dioxide and water in the body Its antibacterial effect is 5-10 times higher than that of traditional sodium benzoate, and its toxicity is only one fifth of that of sodium benzoate, and it will not damage the original color, fragrance, taste and nutritional components of food Do you know the function of potassium sorbate in food? Xiaobian will introduce you The functions of potassium sorbate in food are as follows: 1、 Properties of potassium sorbate potassium sorbate is the product of neutralization reaction of potassium carbonate or potassium hydroxide with sorbic acid as raw material It has the following three advantages: corrosion resistance, safety and stability: 1 Good mould proof effect 2 The product has low toxicity and high safety 3 Do not change food characteristics 4 Wide application range 5 Easy to use 2、 The function of potassium sorbate 1 The structure of sorbic acid is similar to that of glucose, which is favored by microorganisms Therefore, sorbic acid can enter microbial cells through cell walls, inhibit various enzymes in them, and use its double bond to generate an addition reaction with cysteine's sulfhydryl group to destroy enzymes containing sulfhydryl group However, sorbic acid can be excreted quickly in human body, which is harmless to human body 2 Potassium sorbate can improve the preservation of food, so as to prevent food from spoiling; improve and improve the sensory properties of food, including color, fragrance, taste, shape, taste, etc.; improve the processing efficiency of food, adapt to the needs of modern food production mechanization and continuity; improve and improve the nutritional value of food; It can also meet other special needs, such as non nutritional sweeteners to meet the special needs of some patients At present, it has been widely used in food, beverage, pickle, tobacco, medicine, cosmetics, agricultural products, feed and other industries From the perspective of development trend, its application scope is still expanding Food additives have almost become an indispensable problem in the process of food production It's better to use a food safety tester to test them after the completion of production Learning more about food additives can bring benefits to people's diet in the future Among them, what's the role of potassium sorbate?
