papain

Overview:

Papain is a pure natural biological enzyme product extracted from the immature fruit of papaya plant by bioengineering technology. It is composed of 212 amino acids and has a molecular weight of 21000. It belongs to thiol (—SH) endopeptidase. It has the activity of protease and esterase, has a wide range of specificity, and has strong enzymatic hydrolysis ability for animal and plant proteins, polypeptides, esters, amides, etc. This ability can be used to improve the nutritional value or functional properties of animal and plant proteins.

Features:

1. Adopt advanced bioengineering technology, membrane separation technology and vacuum freeze-drying technology, and successfully develop proprietary enzyme protection technology, reduce the loss of enzyme activity during processing, and produce papain enzyme activity of more than 3.5 million units/g.

2. Organize production according to the US Pharmacopoeia standards and current Chinese standards, establish a strict quality control system in accordance with the requirements of the international quality certification system, strictly control the microorganisms in the products, and meet the national export food hygiene standards.

3. To solve the high-efficiency separation of papain by ultrafiltration technology, extract papain protase at room temperature, and the recovery rate of papain protease is over 90%, which improves the recovery rate of the enzyme and reduces the cost.

Product properties: light yellow or white solid powder

Application areas:

Ⅰ. Food industry:

Using the enzymatic reaction of papain, the macromolecular protein in food can be hydrolyzed into small molecular peptides or amino acids that are easy to absorb. It is widely used in animals and plants such as chicken, pigs, cattle, seafood, blood products, soybeans, peanuts Proteolysis, meat tenderizer, wine clarifying agent, biscuit loosening agent, noodle stabilizer, health food, soy sauce brewing and wine starter, etc., can improve the nutritional value of food and reduce costs.

2. Biscuit industry:

Reduce dough wet gluten, improve dough plasticity and physicochemical properties, and hydrolyze protein macromolecules into short peptides and amino acids, which is conducive to complex Maillard reaction of sugars and amino substances, making products color fast and pleasing to the eye It has an oily and bright feeling, loose and crispy, large volume ratio, obvious cross-sectional network structure and good layers; cracked cake and broken cake rate are reduced, the cake shape is full and does not shrink, the pattern is clear, and the cake surface is smooth; and can be reduced accordingly 10 %-25% sodium metabisulfite, thereby reducing the residual amount of harmful substances such as SO2, and can also correct the influence of chemical additives on the flavor of biscuit, and effectively improve the quality of biscuit products.

3. Pharmaceutical industry:

Papain-containing drugs, such as papain throat tablets, papaya enteric-coated tablets (capsules), and papaya lozenges, have anti-inflammatory, choleretic, analgesic, digestive, and immune-enhancing effects. Further studies have shown that they can also be used to examine the surface of red blood cells. And blood type identification agent, treatment of gynecological diseases, glaucoma, insect bites, etc.

4. Textile industry:

The shrinkage resistance of wool: the wool treated with papain has a higher tensile strength than the conventional method, and the wool feels soft, comfortable and resistant.

Shrinkage, tensile strength and other effects have 0 shrinkage; it can also be used for silkworm degumming and silk refining.

5. Leather industry:

Using papain to make leather depilatory, tanned leather, the leather tanned by this product has fine and bright pores.

6. Feed industry:

It decomposes the protein in the feed into amino acids, increases the exudation of nutrients, which is conducive to the absorption and utilization of eggs by poultry, and at the same time supplements the lack of endogenous enzymes in animals, improves feed utilization, reduces feed costs, and enhances appetite, thereby promoting animal growth. Daily weight gain and vitality, and can also be used as an additive for advanced compound fertilizers for vegetables and fruits.

7. Daily chemical industry:

It is used for soap, soap, detergent, washing powder, hand sanitizer, etc. After the clothes are contaminated by blood stains, milk, juice, soy sauce oil, etc., it is generally difficult to remove these stains if ordinary detergent is used. If protease is added to the detergent, sweat and blood stains can be easily removed, with strong detergency, sterilization and disinfection, and safety.

8. Cosmetics industry:

Papain acts on the aging stratum corneum of human skin, promotes its decomposition and degeneration, removes to achieve skin rejuvenation effect and promotes cell growth, and papain hydrolyzate forms an amino acid derivative film on the skin surface to keep the skin moist and smooth ; Papain is easy to form complexes with copper ions in the melanin that forms pigmentation, reducing the formation of melanin and removing the melanin of pigmentation, and the tripeptide substance hydrolyzed by papain can directly inhibit the tyrosine activity of forming melanin, eliminate the Free radical action, so as to achieve the effect of whitening and removing spots

9. In addition, toothpaste, mouthwash, tooth powder, etc. can be added to clean the oral cavity, remove tartar and calculus, and can be used with other solvents to make contact lens cleaning and disinfectant and photosensitive film silver recovery.

vitality:

Definition of enzyme activity: UV spectrophotometry: the trichloroacetic acid soluble matter released by hydrolysis of casein per minute under the determination conditions (37±0.2℃; pH value 7.0) has absorbance at 275nm wavelength and absorbance of 1 μg of tyrosine When equivalent, the required amount of enzyme is an activity unit, expressed in u/g.

The optimum amount of enzyme added must be determined according to the specific production situation. For details, please write or inquire.

store:

It is recommended to store in a cool and dry environment away from light.

Long-term storage or unfavorable storage conditions will reduce the enzyme activity to varying degrees; if the temperature and humidity are too high, it is necessary to appropriately increase the usage amount during use.

Safety:

Papain is a pure natural enzyme preparation, which is a protein. Foods with enzyme preparations are beneficial to the human body just like eating foods containing protein.

For some sensitive people, such as direct ingestion of highly concentrated enzyme powder or droplets, it may cause allergies, and prolonged contact may irritate the skin, eyes and mucous membranes. It is recommended to wear protective equipment such as masks and goggles during the operation. The remaining or spilled enzyme powder should be disposed of in time. For a large amount of enzyme powder spilled, it should be gently swept back to the container, and a small amount should be vacuumed or soaked with water for cleaning.

Papain is a biologically active substance that is easily inhibited and destroyed by heavy metal ions (Fe3+, Cu2+, Hg+, Pb+, etc.) and oxidants, and should be avoided during storage or use.
