What role does food thickener play in food

Introduction: Although we all know that many kinds of food additives are added to food, what's the role of food thickeners in food? We can ask the editor of Baibai safety net about this question, and he will answer it for us Up to now, there are over 40 kinds of food thickeners used in food industry in the world, which are mainly used to improve and stabilize the physical properties or forms of food, increase the viscosity of food, give the food a smooth and palatable taste, and play the role of thickening, stabilization, homogenization, emulsifying gel, masking, flavoring, sweetening and sweetening There are many kinds of thickeners, including natural thickeners and chemical thickeners The natural thickener is mainly obtained from plants, and the chemical thickeners are CMC Na, propyl alginate, etc What's the function of food thickener in food? A brief introduction to the function of food thickener 1 increase viscosity The most intuitive way to use thickener is to increase the viscosity of the product, which can alleviate the gravity sinking of particles to a certain extent However, the viscosity of liquid milk can not be increased without limitation, which will seriously affect the quality and taste of the product The effect of thickener and milk protein Some thickeners can combine with milk protein to a certain extent and play a colloidal protective role For example, carrageenan and casein have certain reactivity, so they can be well used in cocoa milk and other dairy products; for example, PGA and casein have good reactivity under acid conditions, so it can combine with casein under acid conditions to form a hydrophilic protective layer The interaction between thickener and emulsifier The main function of thickener is to increase the viscosity of the system and reduce the separation speed of dispersed particles from water The thickening mechanism of thickener is related to hydrogen bonding, hydrophobic and electrostatic action The interactions between thickener and emulsifier are mainly electric, hydrophobic and dispersive 4 synergistic effect between thickeners Carrageenan and sophora bean gum, xanthan gum and sophora bean gum, tragacanth gum and sodium alginate, tragacanth gum and xanthan gum have synergistic effect By using the synergistic effect of various thickeners and the method of compound compounding, numerous compound adhesives can be produced to meet the different needs of liquid milk production, and the minimum dosage level can be achieved 5 Stability of salt components For example, in neutral pure dairy products, phosphate or citrate can increase the stability of heat treatment to a certain extent In addition, the salts also changed the thickener molecules and emulsifier molecules to some extent, affecting their stability Is it safe to add thickener to food? Food thickener is widely used in food processing It is safe for human body to use approved food thickener reasonably according to national standards It is harmful to human health to add thickener without permission of national standard or to use food thickener beyond the scope or limit The above questions about adding thickeners to food are briefly introduced If you want to know more about food additives, you can pay more attention to food safety knowledge, and more food problems will be answered If you have questions about food safety, you can also use food safety tester to test food safety Editor in charge: he xianrob
