Acidic Protease

The acidic protease is prepared by deep liquid fermentation of Aspergillus niger. It can hydrolyze macromolecular protein to produce polypeptide or free amino acids under acidic conditions. In addition, the substrate catalyzed by pepsin can be further decomposed by the acidic protease.

Features:

1. Appearance: pale white or light brown powder with less than 8% of water content.

2. Activity: 50,000 U/g

3. Temperature: 40-50°C (with optimal temperature of 40°C)

4. pH: 2.5-4.0 (with optimal pH of 3.0) 

Definition of the unit of the enzyme activity: One unit (U/g) is defined as the amount of enzyme needed to hydrolyze casein to produce 1 μg of tyrosine measured as the absorbance value in furin reagent chromogenic reaction in lactic acid - sodium lactate buffer (0.05 mol/L, pH 3.0) at 40°C in 1 min (reaction time is 10 min) (QB/T1803-1993).

Applications:

1. In the production of fruit juice, butter and soy sauce, adding acidic protease clarify the mist in the fermentation broth.

2. In beer brewing, adding acidic protease can effectively block the formation of diacetyl and shorten the maturation of beer.

3. In fur processing, acidic protease can improve the fur coloring,

4. In feed processing, adding acidic protease can decompose the dietary proteins and increase their utilization. The adding amount in animal feeds are as follows:

(1) For soybean meal based diets of laying chickens, broilers, chicklings, ducks, geese, growing pigs: 100-120 g/ton.

(2) For soybean meal based diets of piglets: 120-150 g/ton.

(3) For miscellaneous meal based diets of laying chickens, broilers, chicklings, ducks, geese, growing pigs: 120-150 g/ton.

(4) For miscellaneous meal based diets of piglets: 150-180 g/ton.

Specification: 20 kg/bag

Storage:

Store in dry and cool (below 25°C) area with ventilation. During transportation, avoid direct exposure to strong sunlight, rain and moisture. The enzymes will lose activity at high temperature or under strong sunlight. The enzyme activity can be maintained at least 85% when stored for 6 months. It can be stored for long period at 5°C. It is corrosive to skin and direct contacting with skin and eyes should be avoided.

Analysis on the current pain points of the industry

1. False mark of enzyme activity

The product is marked with 100,000 enzyme activities, and the actual enzyme activity is 60,000, resulting in incomplete hydrolysis and indirectly increasing the cost of enzymes.

2. Product is unstable

Lack of enzyme protection technology and quality control, unstable enzyme activity, and differences in product specifications for each batch, resulting in product quality fluctuations.

3. Long production cycle

No enzymatic hydrolysis experience and enzyme compounding technology increase labor cost and R&D cycle, which indirectly affects the production schedule.

For us, our major is to solve these pain points

1. The enzyme activity can be customized, providing different enzyme activity products and solutions

2. Stable enzyme activity, unique enzyme activity protection technology to reduce fluctuations in production quality

3. Enzyme activity is not false, strict quality control links, third-party testing to reduce enzyme costs

Quality control strength
6 key control point inspections, escorting the whole process of quality, using extraction, membrane separation, vacuum freeze-drying, spray drying and enzyme activity protection technologies to produce products that fully meet the requirements of global customers.
