Neutral Protease NP-100 is produced from non-genetic modified strains of Bacillus subtilis through submerged fermentation, extraction and refining process. NP-100 catalyzes protein hydrolysis in neutral environment and generates peptide and a small quantity of amino acids.
Black Brown Liquid
100,000 U/ml (minimum)
4.0 to 7.0
EFFECT OF PH
NP-100 works at pH ranging from 6.8 to 8.0 with its optimum pH range from 7.0 to 7.5. Inactivation of NP-100 can be achieved quickly at pH below 5.0 or above 9.0.
EFFECT OF TEMPERATURE
NP-100 works at temperatures from 45 to 50°C. Its optimum temperature is 50°C. It is inactivated quickly at temperatures above 60°C.
APPLICATION AND BENEFITS
Hydrolysis of animal protein
NP-100 can be used to hydrolyze meat, fish, terrapin, pig pancreas, silkworm pupae, etc. to
produce peptide and amino acids.
Hydrolysis ofplant protein
Adding NP-100 into soy milk or instant soy milk powder can considerably increase the
yield of proteins and the solid content.
In beer production, inadequate quality of malt or large content of auxiliaries will lead to
insufficient α-amino acid, thus result in insufficient yeast propagation, abnormal
fermentation and unwanted diacetyl content in beer. NP-100 can help to increase α-amino
acid content in beer. Dosage rate depends on the original wort content.
In soy sauce production, proteolysis is the key to maximize raw material utilization and
improve product quality. Use of this enzyme can partly replace Koji will not only increase
the utilization rate of the raw materials but also maintain the desirable flavor and quality of
Treatment of animal blood
Use of NP-100 in the treatment of red cell of blood can produce decolorized and soluble
blood hydrolyte, which can be used in the production of calcium supplements, oral liquid
nutritional supplements, food additives for food and beverage so as to enhance food
PACKAGING, STORAGE & SHELF-LIFE NP-100 is packaged in 25kg, 30kg HDPE drums or 1125 kg IBC totes. Customized packaging is also available upon request.
Typical shelf-life is six months provided it is stored 0∼10°C in its original packaging, sealed and unopened, protected from sunlight. NP-100 has been formulated for optimal stability. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, therefore should be avoided.
SAFE HANDLING OF ENZYMES Inhalation of enzyme dust and mists should be avoided. In case of contact with skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Material Safety Data Sheet.
