Definition of natural colorants

Introduction: according to their sources and properties, colorants can be divided into synthetic colorants and natural colorants Here is the definition of natural colorant Color is one of the important standards to evaluate the appearance quality of food When people judge the quality of food, they often observe the color first Natural, soft and pleasant color can arouse people's appetite and increase consumers' desire to buy On the contrary, if the color of food changes or fades in the process of production, processing and transportation, the quality of food will be greatly reduced In general, we add food colorants to the food for color matching to meet the needs of consumers Here is the definition of natural colorant Food colorant is also called food pigment Food dyes and food colorants can be divided into azo and non azo colorants according to their structures; fat soluble and water-soluble colorants according to their solubility; and natural and synthetic colorants according to their sources Natural colorants are mainly extracted from animal, plant and microorganism tissues by physical methods, while synthetic colorants are organic colorants by artificial chemical synthesis In China, many natural products have a long history, and have been loved by people At present, the development and application of natural food additives is becoming an international trend The development of these traditional products will enable domestic enterprises to occupy a unique leading position in the global market The natural pigment directly comes from the automatic plant, except for gamboge, the rest is harmless to human body The state also stipulates the maximum use amount of each natural edible pigment At present, the allowed natural pigments are turmeric, safflower yellow, capsanthin, shellac pigment, red koji rice, soy sauce, beet red, sodium copper chlorophyllin and β - carotene Because of its sensitivity to light, heat, acid and alkali, it is easy to fade and change color in the process of processing and storage, which affects its sensory properties Therefore, synthetic pigments are sometimes added to foods As an indispensable food additive, food colorant always affects our life China has a vast territory, and the development potential of natural colorant resources is huge To develop natural colorant, in addition to improving the production process and increasing the yield, multi-directional development and comprehensive utilization should also be considered To develop synthetic colorants in a rhythmic way, to conduct a variety of toxicological and analytical chemical studies on the synthetic colorants in use, and to strengthen comprehensive treatment to prevent and control the pollution of colorants in the process of production, processing, transportation and storage Some colorants are used in industry, but some of them are used in food What's the harm of excessive colorants? In fact, a small amount of colorants do not harm people, but excessive use will cause serious harm However, China's food safety detector can accurately check the safety level of food, so consumers can eat it at ease More food safety knowledge is in Baibai safety net Editor in charge: he xianrob
