Potassium sorbate: colorless to white squamous crystal or crystalline powder, odorless or slightly odorous. It's unstable in the air. It can be oxidized and colored. Hygroscopic, soluble in water and ethanol. Mainly used as a food preservative, it is an acid preservative, can react with organic acids to improve the antiseptic effect. Potassium carbonate or potassium hydroxide and sorbic acid as raw materials. Sorbate and potassium SORbate are the most widely used preservatives in the world, which can effectively inhibit the activity of mold, yeast and aerobic bacteria, so as to effectively prolong the preservation time of food and maintain the original flavor of food. When we buy packaged (or canned) food, we often see the words "sorbate" or "potassium sorbate" in ingredient lists, but they are commonly used food additives. Potassium sorbate is an acidic preservative that remains effective in foods that are close to neutral (PH6.0 to 6.5) (not suitable for dairy products). Potassium sorbate is a highly effective and safe preservative recommended by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO). It is widely used in food, beverage, tobacco, pesticide, cosmetics and other industries. As an unsaturated acid, it is also used in the resin, fragrance and rubber industries.1. The actual effect of mold removal is excellent. 2. Low toxic side effects and high safety factor. 3. Do not change the characteristics of food. 4. Wide range of use. 5. Easy to use.1. The animal feed industry, the United States and the European Union all use potassium sorbate as a legal feed additive for animal feed. Potassium sorbate can inhibit the growth of mold in feed, especially the formation of aflatoxin has a very significant effect. Potassium sorbate can be easily digested as a feed component and has no adverse effects on animals. It is not easy to spoil the feed during storage, transportation and sale. 2. Food containers and packaging materials: The purpose of food packaging is to protect the contents. At present, the use of active materials in food packaging to improve the function of materials, in addition to the function of extending the shelf life of packaged food, but also to maintain the nutrition and safety of food. 3, food preservatives: potassium sorbate is widely used as a food preservative, and it is widely used in low-alcohol wine such as fruit wine, beer and wine and has ideal antiseptic effect. Using potassium sorbate to treat packaging materials can extend the shelf life of foods such as bread and dry coolers. (1) Application in vegetables and fruits Fresh vegetables and fruits if not timely preservative preservation treatment will soon lose luster, moisture, dry wrinkled surface and easy to produce mold leading to decay, resulting in unnecessary waste. If the surface of vegetables and fruits using potassium sorbate preservative, in the temperature of up to 30℃ can be stored for a month, but also can keep vegetables and fruits green degree does not change. (2) Applications in meat products Smoked ham, dried sausages, jerky and similar dried meat products are preserved by briefly soaking them in a solution of potassium sorbate at an appropriate concentration. (3) Application in aquatic products Thoroughly cleaned fresh fish, shrimp or other fresh aquatic products, immersed in the appropriate concentration of potassium sorbate preservation solution for 20 seconds after taking out, remove the preservation solution after refrigeration, can effectively extend their shelf life. Adding proper potassium sorbate to dried fish products can effectively prevent the occurrence of mildew. Smoked fish products can be sprayed with a suitable concentration of potassium sorbate solution before, during or after the smoking process. (4) Its application in beverages Potassium sorbate can be added to fruit and vegetable juice drinks, carbonated drinks, protein drinks and other beverages, because the addition of potassium sorbate greatly extends the shelf life of the product. (5) Application in candied fruit and confectionery products Peanut brittle, almond candy and general sandwich candy, can directly add the right amount of potassium sorbate for preservation.1kg/ bag, 15kg/ box, 25kg/ box, 500Kg/ bagWhite crystal, powder.
