Food grade papain for baking and protein hydrolysis

 PRODUCT DESCRIPTION

 The product is extracted from juice of young papaya fruit and then purified and freeze-dried. It’s a high-performing natural plant protease.

MECHANISM

papain is a thiol endopeptidase, i.e., it contains in the active centre a highly reactive cysteine group that is essential for its function. This enzyme hydrolyzes big molecular proteins into easily absorbable small peptides and amino acids.

APPLICATIONS

lImprove digestibility: By hydrolysis into small molecular peptides or amino acids, protein will have much easier to absorb, and therefore, its biological value is greatly improved.

lImprove digestibility: By hydrolysis into small molecular peptides or amino acids, protein will have much easier to absorb, and therefore, its biological value is greatly improved.

lGluten weakening: In baking to make biscuit more crispy or other bakery products less bite resistant.

ØBeauty and Cosmetics Industry

lSkin care: Addition of papain into cosmetic products, where protein, oils and fats are contained, will improve beauty effectiveness of the product in dark spot removal, skin whitening, skin metabolism, and skin rejuvenation. It can also be added into diet tea and relevant products.

ØDaily chemical products

lIncorporation into soap, detergent, washing powder, etc, helps remove stains and microorganisms more efficiently and enhances cleaning effects.

lImprovement of digestibility: Used as feed additive or processing aid, more protein sources can be used for feed, while improving biological value of these proteins.

lDepilation of pelt: The product can used as depilating agent to remove hair of animal skin.

lIf used for wool treatment or silk refining, it can help with the hand feel and shrinkage prevention.

SAFETY AND HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.

WARNINGS

Keep sealed after use every time to avoid moisture adsorption, microbial infections and inactivation of enzymes until its finish.
