The function of color protecting agent

Introduction: color protectors are very common in processed foods, so what are the functions of color protectors? Baibai safety net is introduced in detail Color protecting agent is to improve the color of food in the process of food processing and production, which can extend the shelf life, etc What are the functions of color protecting agent? Many people don't know the function of color protecting agent very well Let's go through the staff of Baibai safety net to learn more about it In addition to the coloring function, the color fixative also has the function of flavor enhancement and bacteriostasis The final effective component of the color fixative is nitrite Hair color function: make meat products present good bright red (main function) bacteriostasis: nitrite has a certain inhibition on the proliferation of microorganisms, and a special inhibition on Clostridium botulinum The growth of Clostridium botulinum, especially Clostridium botulinum, was significantly inhibited when 0.1-0.2/kg nitrite was added to meat products Its effect is affected by pH when pH is 6, it has a significant inhibitory effect on bacteria When pH is 6.5, the effect is reduced When pH is 7, it has no effect at all When it is used together with salt, the bacteriostasis is enhanced Flavor enhancing effect: nitrite can enhance the flavor of cured meat products The flavor of sausage with nitrite was obviously enhanced Antioxidant effect: nitrite has strong antioxidant capacity, can inhibit the oxidation of fat Due to the formation of nitric acid in the chromogenic process, the oxidation of nitric acid is very strong, which will cause part of myoglobin to be oxidized to ferrimyoglobin and turn brown When nitrate and nitrite are used together with L-ascorbic acid, L-ascorbic acid sodium, nicotinamide and other reducing substances as color protecting additives, it can prevent the oxidation of myoglobin, at the same time, it can reduce the oxidized Brown high iron myoglobin to the red reduced myoglobin to help protect the color These are the functions of color protectors, so you have a certain understanding If you want to know more about food additives, you can go to Baibai safety net Will color protectors be harmful to human body?
