Product Description

Main characteristics and functions

1. Highly effective antibacterial: It can effectively prevent the reproduction of molds and yeasts, and also has an inhibitory effect on pathogenic bacteria (such as Salmonella).

2. Good water solubility: It readily dissolves in water and is convenient for uniform dispersion in various liquid or semi-solid products.

3. High safety: Its toxicity is much lower than that of other traditional preservatives, and after entering the human body, it can be metabolized normally into carbon dioxide and water, without accumulating in the body.

Safety explanation

1. It is an internationally recognized safe (GRAS) food additive.

2. Using it within the maximum permitted amount as stipulated by national standards is completely safe and will not cause harm to health.
