Neutral Protease

The neutral protease is prepared by deep liquid fermentation of Bacillus subtilis. As an endoprotease, neutral protease can be used for various proteolysis. It can hydrolyze protein macromolecules into peptones, peptides and amino acids. It has been widely used in food processing, medicine, textile industry, leather processing and feed industry.

Features:

1. Appearance: light brownish powder with less than 8% of water content.

2. Activity: 100,000 U/g

3. Temperature: 40-55°C

4. pH: 6.0-8.0 (with optimal pH of 6.5-7.5).

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 sodium phosphate buffer (0.05 mol/L, pH 7.5) at 40°C in 1 min (reaction time is 10 min) (QB/T1803-1993).

Applications:

1. In food processing, the neutral protease can hydrolyze proteins of dough into peptones, peptides and amino acids. It can reduce dough strength, improve its plasticity and extensibility, and keep its printing pattern clear and beautiful.

2. In pharmaceutical industry, adding neutral protease in drugs can improve the anti-inflammatory, choleretic, analgesic, and digestant effects.

3. In textile industry, the neutral protease can be used for treating wool to improve its tensile strength and handfeel, and minimize its shrinkage. It can also be used for silk degumming and silk refining.

4. In leather processing, the neutral protease can be used for removing hair in tanning and makes the leather clean and glossy. 

5. In feed industry, addition of neutral protease, amylase, cellulase, and semicellulase can enhance the utilization of protein and reduce the feed cost. The amount of addition of neutral protease is as follows (based on the activity of 10,000 U/g)：

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

(2) For miscellaneous meal based diets of laying chickens, broilers, chicklings, ducks, geese, and ruminants: 120-150 g/ton.

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

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

(5) For soybean meal and miscellaneous meal based diets of aquatic animals: 200-500 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 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.
