Antimicrobial and antiseptic effect of sodium nitrite

Antimicrobial and antiseptic effect of sodium nitrite

In daily life, the use of sodium nitrite is not only limited to the construction engineering, printing and dyeing, and metal industries. It is also well-known for its use in food and microbes. Its antimicrobial and antiseptic effects are in various additive products. Medium, the effect is very superior.

Then we need to understand how sodium nitrite achieves the role of antimicrobial agents and preservatives. First of all, it is a strong oxidant. In the same environment, it can react with oxygen due to other elemental substances. If it is in a density space, it will form an oxygen-free state, which will reduce the corruption of the video and prolong the food, Corruption caused by the growth of microorganisms or chemical changes in drugs.

In the process of inhibiting the growth and reproduction of microorganisms, sodium nitrite achieves effects through three ways: 1. Interfere with the enzyme system of microorganisms, inhibit activity and hinder metabolism; 2. Force the protein to denature and prevent survival and reproduction; 3. Change the plasma membrane Permeability, inhibits metabolism and enzymatic reactions, makes cells inactive and will not react.

Sodium nitrite is only one of the preservative products. As its own characteristics, it is also toxic when used as a preservative. When using it, we must pay special attention to the amount of use. It is strictly prohibited to be used in the cured meat and catering industry, except for formal food processing enterprises.

The clear standard for its use is harmless to the human body, does not affect the digestive tract flora, can be degraded into the normal ingredients of food, does not affect the use of antibiotics, and does not produce harmful ingredients when the food is heated. In terms of antiseptic effect, sorbic acid and its salts have strong antibacterial properties and low toxicity, can participate in the normal metabolism of the human body, and have no effect on the taste of food. It is very popular in the world.
