The function of meat color protecting agent

Introduction: color fixative is a kind of chemical substance to improve the appearance of color It is used in many foods What is the function of meat color fixative? Understand through Baibai safety net If meat wants to keep its color good-looking for a long time, the fragrance will not be diffused, and the appearance of oil looks a lot, it needs to add color protectors, especially some cooked foods, which are basically applied to this chemical composition, then what is the function of the color protectors? Learn through the safety net of Baibai The color protecting agent can make meat and meat products have the function of color substance, so that it will not decompose and destroy in the process of food processing and preservation, and present good color substance Because pigments are due to the presence of chromophores and chromophores to present their own characteristic colors However, these groups are easy to be oxidized, reduced and complexed, which changes the structure and properties of the groups, resulting in changes in the energy required for electronic transition, changes in the wavelength of light absorption, and changes in the color or discoloration If we know the factors and mechanism that make the color change, we will choose color protectors to protect the color of food according to the sensitivity of various pigments to these factors For example, the stannous citrate disodium salt obtained by the reaction of stannous chloride with sodium hydroxide and acid (such as citric acid) has certain reduction performance If we use it in canned food, it can gradually interact with the residual oxygen in the can, and stannous ion is oxidized to tetravalent stannic ionon, which shows good antioxidant performance, so as to achieve the protection of food pigment Through understanding, we know the function of color protectors, and we believe that we have a certain understanding Is color protectors harmful to human body? To know these answers, we can go to Baibai safety net, where there are many small knowledge of food additives, such as the use of food safety detector can detect those ingredients in food that are harmful to human body Editor in charge: he xianrob
