• Brief introduction to the product
Green year Brand acid protease preparation is produced via submerged fermentation of Aspergillus usaanii 537 and modern extraction technique. It is a kind of enzyme preparation used to catalyze protein in acid environment. • Function and characteristics This product is applied to hydrolyze the proteins of vegetable and animal in acid medium and acts on inside bond to form small peptides and amino acids. The addition of this product to the processing of alcohol and distilled spirit can promote the growth of yeast to accelerate fermentation speed and improve alcohol productivity. In feedstuff industry, this product can be used as an additive by combined with other enzymes (such as cellulase, pectase andβ-glucanase and so on) for the preparation of complex feedstuff enzymes. It can further improve the nutrition value of feedstuff to accelerate the growth and increase weight of livestock and poultry. • Enzyme activity Acid proteinase: 50,000μ/g
Definition of enzyme activity: The amount of enzyme in 1 gram enzyme powder required to hydrolyze casein to produce 1μg tyrosine per minute at the condition of 40a?? and pH3.0 is defined as one unit of enzyme activity, expressed withμ/g. • Application condition
Optimal pH range: 3.0 to 3.5; Effective pH range: 2.5 to 4.0
Optimal temperature: 40a??; Effective temperature range: 30 to 50a?? • Package and storage
1. Solid products are packed with film bag (2 kg/bag) as inner wrapper and carton as outside wrapper, and net weight of each carton is 20 kg.
2. With the best efforts to avoid insolation and high temperature during the transportation and storage. Keep the environment clean and cool, and it is better to store at low temperature (environmental temperature below 25a??). When stored at 25a?? for six months or at 5a?? for one year, the enzyme activity is not less than 90% of the labeled value. • Application scope
