How to use food color protecting agent

Introduction: many people don't know how to use food color protectors? What is the color protection principle? It is introduced in detail through Baibai safety net The purpose of food color protectors is to make many products keep attractive colors and the shelf life longer How to use food color protectors? Are color protectors harmful to human body? Let's introduce these problems in detail Just put the purchased food color fixative in the product, add the right amount of water, and then it is finished Color protectants are mainly used in meat In the process of storage and processing of meat, 2-valent iron ions in myoglobin are oxidized to high iron myoglobin (brown), the color of meat will turn brown, if it is re oxidized, the porphyrin structure will be oxidized to oxidized porphyrin, and the color of meat will be green or yellow If nitrate is added to meat products, it will react with myoglobin to produce bright, bright red nitroso myoglobin (mbno), making meat products bright red NaNO2 + CH3CHOHCOOH → HNO2 + ch3chohcoona MB + no → mbno, because nitrate is reduced to nitrite under the action of bacteria, nitrite is regenerated to nitrite due to the action of lactic acid in meat, nitrite is unstable under normal temperature, the decomposed nitrite (no) reacts with myoglobin to generate nitroso myoglobin These are the reaction process of color protectors and meat It's easy to use and very simple So, Baibai safety net has the most detailed knowledge of food additives In our life, we can use food safety detector to test food safety Editor in charge: he xianrob
