What are the precautions for people

Jul 15, 2019

Preservatives may bring certain troubles to people's health. Most of the preservatives used in food production in China are synthetic. If used improperly, there will be certain side effects. Some preservatives even contain trace amounts of toxins. Ingestion can cause certain damage to human health. For example, the widely used food preservative benzoic acid has been controversial internationally. For example, due to reports of poisoning of benzoic acid and its sodium salt, EC Children's Protection Group considers it unsuitable for children's food. In Japan, Japan has also imposed strict restrictions on its use. Even if it is one of the internationally recognized safe preservatives, sorbic acid and potassium sorbate, excessive intake will affect the balance of human metabolism.

Mechanism of action of food preservatives

1. Food preservatives can cause microbial proteins to coagulate or denature, thereby interfering with their growth and reproduction.

2, food preservatives can destroy or damage the cell wall or can interfere with the mechanism of cell wall synthesis, resulting in the leakage of intracellular substances or affect the membrane-related respiratory chain electron transport system, thus having an anti-microbial effect.

3. Food preservatives act on genetic material or genetic particle structure, which in turn affects the replication, transcription, and translation of genetic material.

4. The food preservative acts on the enzyme system of the microorganism, inhibits the activity of the enzyme, and interferes with its normal metabolism.
