PRODUCT DESCRIPTION

Food grade powder acid protease enzyme for protein cleaning

INTRODUCTION

Acid Protease (APRS) is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. The enzyme catalyzes the hydrolysis of protein under acid condition. The main applications cover alcohol fermentation, leather, softening, wool dyeing, juice clarification and feed additives, etc.

MECHANISM

Acid protease (APRS) is a water-soluble product capable of breaking down peptide bonds in proteins. It degrades protein and improves protein’s dispersibility, solubility, palatability and digestibility.

PRODUCT STANDARD

The product complies with GB1886.174.

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 0.01-0.5kg/t DS. The dosage has to be optimized based on each application, the raw material pecifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.

PACKAGE DAN STORAGE

Package:25kg/drum.

Storage: Keep sealed in a dry and cool place and avoid direct sunlight.

Shelf life: 12 months in a dry and cool place.

SAFETY

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