What is the mold inhibitor made of? | Valorchemical—animal feed additives

1.Sorbic acid and its salts: effective at pH values below 5-6. Sorbic acid can participate in the metabolism of the body without residues and good safety. The added amount is 0.05% -0.15% of the feed. Mostly used with other antifungal agents to expand the antibacterial spectrum and increase the antifungal effect. Generally, 0.6% -10% of sorbic acid is dissolved in liquid fatty acids (such as acetic acid, propionic acid, etc.) of 2 to 4 carbon atoms or a mixture thereof, and it can also be dissolved in other solid organic acid antifungal agents simultaneously Into a composite antifungal agent. Treating various grains and feeds with this kind of compound antifungal agent has excellent antibacterial effect.

2.Compound mold inhibitors: The main ingredients are propionic acid, propionate and acetic acid, benzoic acid, sorbic acid, and fumaric acid. In addition to anti-mildew, it also has an appetite enhancement effect.

3.Propionic acid and its salts: the most commonly used mold inhibitors in feed, which has a significant inhibitory effect on molds, and also has a good inhibitory effect on aerobic bacillus or gram-negative bacteria, but it has a good effect on yeast and The inhibitory effect of other bacteria is weak. The amount added in feed is based on propionic acid, which is generally about 0.3%.

4.Benzoic acid and sodium benzoate: It is an acidic mold inhibitors. It participates in metabolism in the body, does not accumulate, and has low toxicity. It is suitable for acidified food and feed. Under low pH conditions, it has a broad inhibitory effect on microorganisms, but it has a weak effect on acid-producing bacteria. When the pH is 5.5 or more, there is no inhibitory effect on many molds. The optimum pH range is 2.5-4.0. The maximum usage should be less than 0.1% based on benzoic acid (1 g of sodium benzoate is equivalent to 0.846 g of benzoic acid).

5.Dehydroacetic acid and its sodium salt: Dehydroacetic acid has an antibacterial effect even in a relatively high pH range. It mainly has higher antibacterial effect on yeasts and molds, and higher doses also have effects on some bacteria. The recommended amount of feed is 0.002% -0.15%.

Fumaric acid and its esters: Compared with other mold inhibitors, it has a strong antibacterial effect and a broad antibacterial spectrum, and has effects on fungi and bacteria. Its antifungal effect greatly exceeds propionic acid, sorbic acid, benzoic acid, etc. In addition, its antibacterial effect is not greatly affected by the pH value, and the adaptive pH range is 3-8. The added amount in feed is generally 0.025% -0.08%.
