The correct use of potassium sorbate

Introduction: there is a lot of knowledge about potassium sorbate We need to know more about potassium sorbate How to use potassium sorbate? In this article, I have introduced potassium sorbate, which is still unfamiliar to people We need to know more about potassium sorbate, which is helpful to understand the ingredients in food What is the correct way to use potassium sorbate? Next, I will introduce it to you Potassium sorbate is the scientific name of hexadiene - (2,4) - potassium sorbate Colorless to white scaly crystal or crystalline powder, odorless or slightly smelly Unstable in the air It can be oxidized and colored Molecular weight 150.22 Hygroscopic Soluble in water and ethanol Potassium sorbate can effectively inhibit the activity of mold, yeast and aerobic bacteria, and prevent the growth and reproduction of harmful microorganisms such as Botox, Staphylococcus, Salmonella, etc., but it has almost no effect on the beneficial microorganisms such as anaerobic bacillus and Lactobacillus acidophilus, and its effect of inhibiting development is stronger than bactericidal effect, so as to effectively prolong the storage time of food, and Keep the flavor of the original food Its antiseptic effect is 5-10 times that of the same kind of product sodium benzoate It has high safety, good stability and wide range of use As potassium sorbate is an unsaturated fatty acid salt, it can be absorbed by the metabolism system of human body and quickly decompose into carbon dioxide and water, without residue in the body The toxicity of ADI 0-25mg / kg (calculated by sorbic acid, FAO / who 1994) ld504920mg / kg (rat, oral) Gras (FDA, 182.3640 1994) was only 1 / 2 of that of table salt and 1 / 40 of that of sodium benzoate Potassium sorbate can be directly added, sprayed, impregnated, dried powder spray, and processed on packaging materials when used There are incompatibility with alkali, oxidant and reductant When it comes to nonionic surfactants and plastics, the antibacterial activity of sorbic acid will be reduced Heavy metal salts can catalyze the oxidation reaction Sorbic acid can also react with sulfur-containing amino acids, but the reaction can be inhibited by adding vitamin C, propyl gallate or butylhydrotoluene When the solution is stored in a glass container, it is very sensitive to pH Therefore, it is necessary to detect the amount of microbe after using potassium sorbate as preservative for a long time If sorbic acid solution is stored in polypropylene, PVC or polyethylene containers without antioxidant, sorbic acid will degrade quickly Food additives have almost become an indispensable problem in the process of food production It's better to use the food safety detector to test it after the completion of production Learning more food additive knowledge can bring benefits to people's diet in the future, including the function of potassium sorbate , you can log in our safety net to check Editor in charge: he xianrob
