Acid Protease, Form : Powder for Industrial

Acid Protease – Uses in Sugar, Ethanol & Distillery Industries

Acid protease is a protein-degrading enzyme that works in acidic environments. It is widely used in fermentation-based industries such as ethanol production, molasses-based distilleries, and sugar processing, where it enhances nutrient availability, improves yeast performance, and reduces residual protein buildup.
