How to use potassium sorbate

Introduction: potassium sorbate people can probably understand, so how to use potassium sorbate? It is introduced in the article We all know some knowledge of potassium sorbate In fact, there is a lot of knowledge about potassium sorbate Now our editor will introduce the production mode of potassium sorbate and how to use potassium sorbate Production mode of potassium sorbate: 1 Neutralization method is mainly used It is obtained by neutralization reaction of sorbic acid with potassium carbonate or potassium hydroxide 2 Add sorbic acid into the reactor, then add 66% water of sorbic acid mass, drop 49% potassium hydroxide solution at 45 ℃, until the reaction solution pH = 8, the reaction takes about 45 minutes Add a certain amount of activated carbon, vacuum filtration, and evaporate the filtrate at 40-45 ℃ for 3-4 hours to meet the requirements, then heat up to 70 ℃ for discharging After centrifugation, crystallization was obtained and mother liquor was recovered Finally, the product was dried at 105 ℃ The use of potassium sorbate can be directly added, sprayed, soaked, dried powder spray, and treated on packaging materials when used Potassium sorbate is incompatible 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 For the sake of our own health, it's better to have a food safety detector in our daily life It's suggested that we should pay attention to healthy diet, and more food safety knowledge, such as: is potassium sorbate harmful to human body? This kind of knowledge is in our safety net Editor in charge: he xianrob
