What are the compound food additives

Introduction: compound food additives refer to the food additives that are physically mixed by more than two single varieties of food additives What are the compound food additives? In recent years, China's condiment industry has developed greatly Enterprises rely on science and technology, adopt new technology and equipment through scientific research, create new products, and ensure the quality of products with strict quality management, while increasing varieties, they also make products reach large-scale production What are the compound food additives? Let's have a look with Baibai safety net Compound food additives mainly include compound nutrition fortifier, compound antiseptic, compound antioxidant, compound flavoring agent, compound gel, compound emulsifier, compound sweetener, compound acid agent, compound swelling agent, composite coagulant, compound quality improver, compound color protecting agent and compound defoamer Food additives have the following three characteristics: first, they are substances added to food, so they are generally not consumed as food alone; second, they include both synthetic and natural substances; Third, the purpose of adding to food is to improve the quality, color, fragrance and taste of food, as well as the needs of antisepsis, preservation and processing technology! Ester type preservatives include p-hydroxybenzoic acid esters (a, B, C, isopropyl, D, isobutyl, heptyl, etc.) High cost It has a wide range of antibacterial effects on mold, yeast and bacteria It has a strong effect on mold and yeast, but a poor effect on bacteria, especially Gram-negative bacteria and Lactobacillus The mechanism of action is to inhibit the activities of respiratory enzymes and electron transfer enzymes, and to destroy the cell membrane structure of microorganisms The ability of bacteriostasis increased with the increase of alkyl chain, and the solubility decreased with the increase of the length of ester based carbon chain, but the toxicity was opposite However, the combination of ethyl p-hydroxybenzoate and propyl ester can increase its solubility and enhance its efficiency It can be absorbed completely and rapidly in gastrointestinal tract, hydrolyzed to p-hydroxybenzoic acid and excreted from urine without accumulation in the body Only propyl ester and ethyl ester are used in China I hope the above contents can help you to learn more about food Please pay attention to Baibai safety net Editor in charge: Mu Danping
