What is the function of thickener

Introduction: thickener is used in all fields of our production and life What's the function of thickener? Is it safe to add thickener to food? Let's get the answer from Baibai safety net Thickener, also known as gelling agent, is also known as paste or food gel when used in food It can increase the viscosity of the system and keep the system in a uniform stable suspension state or opacification state, or form a gel Widely used in food, coating, adhesives, cosmetics, detergents, printing and dyeing, rubber, medicine and other fields Thickeners are mostly hydrophilic polymer compounds, which can be divided into animal, plant, mineral, synthetic or semi synthetic according to their sources It can be simply divided into two categories: natural and synthetic Most of the natural products are made from the plants and seaweeds containing polysaccharide viscous substances, such as starch, pectin, agar, gelatin, seaweed fat, carrageenan, dextrin, astragalus, polysaccharide derivatives, etc; The synthetic products include methylcellulose, carboxymethylcellulose, polyanionic cellulose and other cellulose derivatives, starch derivatives, casein, sodium polyacrylate, polyethylene oxide, polyvinyl pyrrolidone, polyvinyl alcohol, low molecular polyethylene wax, polyacrylamide, etc What's the function of thickener? It's introduced that the thickener in pigment printing consists of thickener, water, binder and pigment paste Under the mechanical force of printing paste re printing, shear force occurs, which greatly reduces the viscosity of printing paste; When the shear force disappears, it returns to the original high viscosity, which makes the printing outline of the fabric clear The viscosity change with shear force is mainly realized by thickener In the manufacture of re latex paint, thickener plays a coordinating role in thickening, stability and rheological properties of latex paint In the process of latex polymerization, it can be used as a protective colloid to improve the stability of the emulsion When the pigment and filler are dispersed, the viscosity of the dispersed material will be increased and dispersed During the storage and transportation process, the stability and the freeze-thaw resistance of the coating will be improved, and the pigments and fillers will be prevented from caking Then the viscosity of the latex paint will be adjusted and the thixotropy will be good Adding several thousandth of food thickeners in food has the functions of gelation, film formation, water holding, suspension, emulsification, foam stabilization and lubrication It plays a very important role in the color, fragrance, taste, structure and relative stability of liquid food or gel food Is it safe to add thickener in food? The use of thickener in food is approved by our country, but the dosage of thickener is limited As long as it is safe to add within the allowed range, many businesses may choose unqualified thickener or excessive use for their own interests, which will bring harm to human health Therefore, we should learn more about food additives by learning food safety knowledge, so that we can have a deeper understanding of thickeners Editor in charge: he xianrob
