Food Bleach Food Bleach Introduction Food bleach is a chemical substance widely used in food processing, and its main role is to inhibit or eliminate harmful microorganisms in food and improve the color and taste of food. However, due to the toxicity of food bleach, the dosage and method of use need to be strictly controlled during use.
1. Types of food bleach.
Food bleach is mainly divided into oxidizing and non-oxidizing types. Oxidizing bleaching agents include sodium hypochlorite, hydrogen peroxide, etc., which destroy the cellular structure of microorganisms through oxidation, so as to achieve the purpose of sterilization and disinfection. Non-oxidizing bleaching agents include sulfur dioxide, sodium sulfite, etc., which reduce the pigment in food to colorless substances through reduction, so as to achieve the purpose of improving food color.
Second, the use of food bleach.
1.Oxidizing bleach: Put the food that needs to be processed into a certain concentration of oxidative bleach solution, soak it for a period of time, take it out, and rinse it with water. It is important to note that oxidized bleach has a certain pungent odor and therefore needs to be used in a well-ventilated environment.
2.Non-oxidizing bleach: Put the food that needs to be processed into a non-oxidizing bleach solution of a certain concentration, soak it for a period of time and take it out, and rinse it with water. It should be noted that non-oxidizing bleach has a certain degree of reducibility, so it needs to be stored in a dark and dry environment.
3. Precautions for food bleach.
1.When using food bleach, it is necessary to strictly control the dosage and use method to avoid harm to the human body.
2.Food bleach is corrosive, so you need to pay attention to safety during use.
3.The use of food bleach needs to be carried out under the premise of complying with relevant national regulations and standards.
Fourth, the application range of food bleach.
Food bleach is widely used in various food processing processes, such as fruits, vegetables, meat, aquatic products, etc. In fruit processing, food bleach can be used to clean pesticide residues and microorganisms on the surface of fruits;In vegetable processing, food bleach can be used to improve the color and taste of vegetables;In meat processing, food bleach can be used to inhibit the growth and reproduction of microorganisms;In aquatic product processing, food bleach can be used to improve the color and taste of aquatic products.
5. The safety of food bleach.
Food bleach is safe under normal use, but excessive or improper use can be harmful to the human body. Therefore, when using food bleach, it is necessary to strictly comply with relevant national regulations and standards to ensure food safety. At the same time, consumers also need to pay attention to the processing and use of food when buying and using food, and avoid excessive or improper use of food bleach.
In short, food bleach is an important food processing aid, but it needs to be used under the premise of complying with relevant national regulations and standards. In the process of use, it is necessary to strictly control the dosage and use method to ensure food safety and the health of consumers.
