Application Scope
1. Antiseptic Characteristics: The antibacterial effect is affected by pH (the minimum inhibitory concentration is 0.01% at pH5.0 and 0.5% at pH6.5). It has a strong inhibitory effect on molds, aerobic spore - forming bacilli, and gram - negative bacilli, can prevent aflatoxin, and has no effect on yeasts.
2. Leather - making Application: As a masking agent to improve the alkali resistance and tanning uniformity of leather.
3. Food Preservation: Used in pastries (addition amount ≤2.5g/kg), bayberry soaking liquid (maximum 50g/kg) to extend the shelf - life.
4. Feed Anti - mildew: The general addition amount is 0.1 - 0.3% to inhibit feed mildew.
5. Cosmetic Use: Preservative (addition amount ≤2%), broad - spectrum antibacterial against molds and yeasts, and more effective under acidic conditions.
