Liquid microbial inhibitor with added antioxidants designed for protection against microbial growth and oxidation in hominy chop and associated animal feed ingredients. Grain by-products such as chop and bran from a wet milling process are high in moisture and have short shelf lives. The organic acids and antioxidants in Hombanox L are powerful enough to inhibit the challenges of moulds, yeasts and acetic acid bacteria and extend the shelf life of these high risk raw materials. Dosing options available.
