Product introduction

ACldic Protease is an enzyme preparation that catalyzes protease hydrolysis in acidic environment (pH 2.5-5.0), appearance: yellow brown powder, enzyme activity: 700,000 U/g. Implementation standard: Implementation of the People's Republic of China industry standard, QB1805.3-93.

Scope of application

Suitable for hydrolyzing animal and plant proteins in acidic media. This product is only used for research in the field of scientific research, not edible or for food production.

Usage method

Grain fermentation in the production of alcohol, the amount is generally 10-15 units per gram of raw material, should be based on raw materials and specific process conditions. 2, in the feed industry, food processing industry dosage, the user should be determined according to the actual situation, the reference dosage is 5-10u/g. 3, in soy sauce brewing, add 25 units; In the solid liquor fermentation, add 20 units. 3. Liquor industry: This product is used for the production of alcohol and liquor industry with starch as raw material, increasing the liquor yield by 0.25% and improving the fermentation speed. Food industry: food is used for starch improvement, improve food flavor, improve quality, because it can increase amino acid content. In beer production: can effectively block the formation of diacetyl, shorten the beer maturation period. Feed additives: Improve feed utilization. Fur softening: improve the color rate, feel full, increase the luster of the fur. The recommended initial addition for the experiment begins with one part per million of the mash. Recommended use: Dissolve the acid protease in 35-40℃ warm water at 1:20 first, soak and activate for 1 hour, stirring every 15 minutes during the period. Application note: 1. When using acid protease solid products, it should be dissolved in warm water at 30-40℃ at a ratio of 1:20. Soak and activate for 60 minutes and stir well before use. 2. When the acid protease is used in the fermentation industry, the fermentation speed is accelerated, the fermentation process is heated up fast, and the temperature must be strictly controlled not to exceed 40 ° C, otherwise the use effect will be affected.
