Acid Protease Enzyme For Protein Cleaning
Introduction
Acid Protease (APRL) is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. The enzyme catalyzes the hydrolysis of protein under acid conditions. The main applications cover alcohol fermentation, leather softening, wool dyeing, juice clarification, and feed additives.
Mechanism
Acid protease (APRL) is a product capable of breaking down peptide bonds in proteins. It degrades protein and improves protein’s dispersibility, solubility, palatability, and digestibility.

Application
- Fuel ethanol industry: Improve alcohol yield by hydrolyzing proteins to generate more free α-amino nitrogen, promoting yeast growth and alcohol fermentation, increasing ethanol yield, and reducing fermentation time.
- Food industry: For baking, the product can improve sensory properties of bread and cake, and for sausage it will improve the flavor/taste and overall quality. It can also be used for soy sauce production to increase amino acid content and beer cold haze prevention.
- Brewing industry: Check the formation of diacetyl and shorten beer maturation time.
- Feed industry: Improve digestibility or biological value of feed; reduce production cost.
- Leather industry: Make fur more shiny and improve fur dyeing.
Recommended Dosage
The recommended dosage is 0.01-1L/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectation, and processing parameters. It is better to begin the test with the convenient volume.

Safety
Enzyme preparations are proteins that may induce sensitization and cause allergic-type symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes, or nasal mucosa. Any direct contact with the human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
