Product Introduction

Potassium Sorbate (C6H7KO2) is the potassium salt of sorbic acid. E202 preservative is a white, crystalline powder or granular substance with a slightly bitter taste. The compound is a synthetically derived preservative commonly used to extend the shelf life of various food and beverage products.

Potassium sorbate for sale is a food additive that acts as a preservative by preventing the growth of microorganisms, thus inhibiting spoilage. Potassium sorbate preservative is particularly effective against molds and yeasts. Due to its antimicrobial properties, potassium sorbate is frequently utilized in the production of a wide range of food items, including baked goods, dairy products, beverages, and more.

Potassium Sorbate can effectively restrain the mold, yeast and oxygen activity of bacteria, staphylococcus aureus, salmonella and other harmful microorganism growth and reproduction, but for anaerobic bacillus bacteria and lactobacillus acidophilus beneficial microbes such as null and void, almost against the effect of development was stronger than the sterilization effect, so as to effectively prolong food to save time, and keep the original flavor of food.

Application

As a food preservative, potassium sorbate is widely used in food and feed processing industries, and is also used in cosmetics, resins, spices and rubber industries. However, it is most widely used in food preservation and feed.

Animal feed industry
Potassium sorbate can inhibit the growth of mold in the feed, especially the inhibition of the formation of aflatoxin has a very significant effect, so adding potassium sorbate can effectively avoid the spoilage of the feed. In addition, the neutral taste of potassium sorbate is suitable for use in feed, because animals are more sensitive to changes in the taste of food than humans. In addition, as an unsaturated fatty acid, potassium sorbate can be easily digested as a feed ingredient without any adverse effects on animals.
Food containers and packaging materials
In terms of plastic production, it can be used in an appropriate amount according to production needs. For rubber, the amount used is 0.1%, and for paper, it can be used according to production needs. At the same time, there is no requirement for the residual amount of sorbic acid.
Food preservatives Potassium sorbate is widely used as a food preservative, and the allowed concentration in noodle products, pickles, canned food, dried fruits, dairy products and condiments is 0.02% to 0.1%.
