What kind of food additive is sodium citrate

Introduction: sodium citrate is also a kind of food additive It is used in food What kind of food additive is sodium citrate? Do you know what kind of food additive sodium citrate is? In fact, as an additive, sodium citrate is widely used in food, medicine, detergent and other fields As a food additive, it is mainly used as buffer, chelating agent, nutritional supplement, emulsifier, seasoning agent, stabilizer, etc In biscuits, beverages, ice cream, dairy products, cans and other food used to improve the flavor of food and improve the quality of products Sodium citrate is the most important citrate at present It is mainly produced by the fermentation of starch to produce citric acid, and then neutralized with alkali It has a variety of unique and excellent properties 1 Because the raw material of preparing sodium citrate basically comes from grain, it is absolutely safe and reliable, and will not harm human health The food and Agriculture Organization of the United Nations and the world health organization do not impose any restrictions on their daily intake They can be considered as non-toxic 2 Sodium citrate is biodegradable After being diluted by a large amount of water in nature, part of sodium citrate becomes citric acid, and both of them coexist in the same system Citric acid is easy to be biodegraded in water by the action of oxygen, heat, light, bacteria and microorganism The decomposition pathway is generally transformed into carbon dioxide and water by aconitic acid, itaconic acid and caraganic anhydride 3 Sodium citrate has the ability of metal ion complexation Sodium citrate has good complexation ability to calcium, magnesium and other metal ions, and to other metal ions, such as iron ion plasma 4 Sodium citrate has excellent solubility, and the solubility increases with the increase of water temperature 5 Sodium citrate has good pH regulation and buffering properties Sodium citrate is a kind of weak acid and strong alkali salt It can be used as a pH buffer when it is mixed with citric acid Therefore, it has important use in some occasions where it is not suitable for the wide range change of pH In addition, sodium citrate has excellent retarding and stabilizing properties Nowadays, many foods have food additives, so what is food additives? In fact, food additives are synthetic or natural substances added into food to improve the quality of food such as color, fragrance and taste, as well as the needs of antisepsis and processing technology Some food additives are harmful to human body, but China's food safety detector can accurately check whether the food is safe and whether there is excessive use of additives, so that we can eat food more safely If you want to know more about food additives, please go to Baibai safety net Editor in charge: he xianrob
