Papain powder

CAS No.: 9001-73-4
Molecular Weight: NA g/mol
Chemical Formula NA

Papain also known as Papaya proteinase I is a proteolytic enzyme extracted from the raw fruit of the papaya plant. Proteolytic enzymes help break proteins down into smaller protein fragments called peptides and amino acids. This is why papain is a popular ingredient in meat tenderizer. Papain is a popular folk remedy to reduce pain, inflammation, and swelling. It has also been used to improve digestion and to treat infections, diarrhea, and allergies. Papain may also ease digestive symptoms like constipation and bloating. Papain is used in cosmetics, toothpaste, contact lens cleaners, meat tenderizers, meat products, animal feed and poultry feed.

Specifications of Papain USP Grade:
Papain --- [CAS 9001-73-4].

DEFINITION
Papain is a purified proteolytic substance derived from Carica papaya Linné (Fam. Caricaceae). Papain, prepared as directed in the Assay, contains NLT 6000 Units/mg. Papain of a higher digestive power may be reduced to the official standard by admixture with papain of lower activity, lactose, or other suitable diluents.
One USP Unit of Papain activity is that which releases the equivalent of 1 micro-g of tyrosine from a specified casein substrate under the conditions of the Assay, using the enzyme concentration that liberates 40 micro-g of tyrosine per mL of Sample solution.
