What is the food additive that can show red effect

Introduction: there are many kinds of food additives with different functions, so what kind of food additives can present red effect? Food additive is a kind of chemical synthetic substance or natural substance used to improve food quality, prolong food preservation period, facilitate food processing and increase food nutrition So what is the food additive that can show red effect? Colorant, also known as pigment, is a kind of substance that can improve the sensory properties of food after coloring According to their properties and sources, edible pigments can be divided into two categories: edible natural pigments and edible synthetic pigments 1 Edible synthetic pigment belongs to synthetic pigment Characteristics of edible synthetic pigment: bright color, stable property, strong coloring power, strong firmness, free color, low cost and convenient use But most synthetic pigments are harmful to human body Some of the toxicity of synthetic pigments are direct toxicity to human body due to their chemical properties, some of them may produce harmful substances in the process of metabolism, and they may also be polluted by arsenic, lead or other harmful compounds in the process of production At present, amaranth, carmine, cherry red, new red, alluring red, lemon yellow, sunset yellow, bright blue, indigo and their respective aluminum lakes are allowed to be used in China And β - carotene, sodium copper chlorophyllin and titanium dioxide Color protecting agent is also called hair color agent In the process of food processing, in order to improve or protect the color of food, in addition to using pigment to directly color the food, sometimes it is necessary to add a proper amount of hair color agent to make the product present a good color 1 Chromogenic principle and other functions of chromogenic agent: ① chromogenic function, in order to make meat products bright red, add more nitrate (sodium or potassium) or nitrite in the processing process Nitrate is reduced to nitrite by bacterial nitrate reductase Nitrite will form nitrite in acid condition At room temperature, it can also decompose to produce nitroso (no) At this time, the generated nitroso will react with myoglobin quickly to generate stable, bright and bright red nitromyoglobin Therefore, the meat can be kept stable and bright ② Bacteriostatic effect: nitrite in meat products has a certain effect on inhibiting the proliferation of microorganisms Nowadays, many foods have food additives, so what is food additives? In fact, food additives are synthetic or natural substances added into food to improve the quality of food such as color, fragrance and taste, as well as the needs of antisepsis and processing technology Some food additives are harmful to human body, but China's food safety detector can accurately check whether the food is safe and whether there is excessive use of additives, so that we can eat food more safely If you want to know more about food additives, please go to Baibai safety net Editor in charge: he xianrob
