Precautions for use of thickener

Introduction: thickener has certain application in our industrial production and food processing What are the precautions for thickener? Is it safe to add thickener to food? Let's have a survey Food thickener: it refers to the macromolecular substance that can dissolve in water and fully hydrate under certain conditions to form a viscous and greasy solution, also known as food glue It is a kind of important food additive which is widely used in food industry and is used as gelling agent It is a kind of food additive that can improve the physical properties or tissue state of food and make food stick and smooth and palatable Thickener can also play the role of emulsification and stability The commonly used thickeners are gelatin, sodium caseinate, Arabic gum, tamarind polysaccharide gum, sesbania gum, agar, sodium alginate (sodium alginate, alginate), carrageenan, pectin, xanthan gum, β - cyclodextrin, sodium carboxymethylcellulose (CMC Na), sodium starch phosphate (sodium starch phosphate), sodium carboxymethyl starch, hydroxypropyl starch and propyl alginate (PGA) The amount of food thickener needed to be added in food is very small, which is usually several parts dry, but it can effectively and economically improve the stability of food system Most of its chemical components are natural polysaccharides and their health products (except that gelatin is composed of amino acids), which are widely distributed in nature What are the precautions for using thickener? Baibai safety net According to the small edition, the use of thickener in food should pay attention to the dosage standard, which is only safe if it is used within the specified range Before using thickener, it must be soaked in cold water for several hours to avoid a large number of bubbles and rigid blocks caused by the final expansion during heating After the full expansion, it should be heated by water separation, and the temperature of glue liquid should be controlled below 70 ° C Make it completely dissolved before use The glue liquid that has not been used up shall be stored in a cold storage or a cool and ventilated place, so as to avoid hydrolysis and deterioration of the glue, which may affect the use Is it safe to add thickener in food? As a kind of food additive approved by the state, as long as it is added within the specified scope of use, it will not harm the human body and is safe, but if it is used excessively for a long time or the food containing thickener is eaten for a long time, it will have an impact on human health Therefore, we must pay attention to the dosage when using thickener, and do not always eat foods containing thickener You can learn food safety knowledge, learn to use food safety detector, and learn more about food safety problems, which will help us choose relatively safe food Editor in charge: he xianrob
