Papain

summary:

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 with a molecular weight of 21000. It belongs to sulfhydryl (- SH) containing endopeptidase. It can hydrolyze the carboxyl ends of arginine and lysine in proteins and peptides. It has protease and esterase activities and has a wide range of specificity, It has strong enzymatic hydrolysis ability for animal and plant proteins, peptides, esters, amides, etc. at the same time, it also has the ability of synthesis. It can re synthesize protein substances from protein hydrolysates. This ability can be used to improve the nutritional value or functional properties of animal and plant proteins.

Product features:

1. Advanced bioengineering technology, membrane separation technology and vacuum freeze-drying technology are adopted, and proprietary enzyme protection technology is successfully developed to reduce the loss of enzyme activity in the processing process. The enzyme activity of papain production exceeds 3.5 million units / g, exceeding the highest level in foreign countries.

2. Organize production according to USP standards and current Chinese standards, establish a strict quality control system according to the requirements of international quality certification system, strictly control microorganisms in products, and meet the national hygienic standards for exported food.

3. It solves the high-efficiency separation of papain by ultrafiltration technology, extracts papain sperminase at room temperature, and the recovery rate of papain pulp is more than 90%, which improves the recovery rate of enzyme and reduces the cost.

Application fields:

1. Food industry:

The enzymatic reaction of papain can hydrolyze macromolecular proteins in food into easily absorbed small molecular peptides or amino acids. It is widely used in animal and plant proteolysis such as chicken, pig, cow, seafood, blood products, soybean, peanut, meat tenderizer, wine clarifier, biscuit loosening agent, noodle stabilizer, health food Soy sauce brewing and wine starter can not only improve the nutritional value of food, but also reduce the cost.

2. Biscuit industry:

Reduce the wet gluten of dough, improve the plasticity and physicochemical properties of dough, and hydrolyze protein macromolecules into short peptides and amino acids, which is conducive to the complex Maillard reaction of sugars and amino substances, so as to make the product color fast, pleasing color, oily and fresh, loose, crisp, large specific capacity, obvious cross-section network structure and good level; The rate of cracked and broken cakes is reduced, the cake shape is correct and full without shrinking, the pattern is clear, and the cake surface is smooth; It can also reduce 10% - 25% of sodium pyrosulfite, so as to reduce the residue of SO2 and other harmful substances. It can also correct the impact of chemical additives on the flavor of biscuits and effectively improve the quality of biscuit products.

3. Pharmaceutical industry:

Papain containing drugs, such as papaya throat moistening tablets, papaya enteric coated tablets (capsules) and papaya buccal tablets, have the effects of anti-inflammatory, cholagogic, analgesic, digestive aid and improving immunity. Further research shows that they can also be used to check the surface of red blood cells and blood group discriminators, treat gynecological diseases, glaucoma, insect bites, etc.

4. Textile industry:

Anti shrinkage of wool: the tensile strength of wool treated with Papain is higher than that of conventional methods. The wool feels soft, comfortable, anti shrinkage and tensile strength. The shrinkage is 0; It can also be used for degumming silkworm and refining silk.

5. Leather industry:

The depilatory agent made of Papain is used for tanning leather. The leather tanned by this product has fine and bright pores.

6. Feed industry:

Decompose the protein in the feed into amino acids, increase the exudation of nutrients, which is conducive to the absorption and utilization of eggs by poultry. At the same time, supplement the lack of animal endogenous enzymes, improve feed utilization rate, reduce feed cost, enhance appetite, so as to promote animal growth, improve daily weight gain and vitality. It can also be used as an additive for high-grade compound fertilizer for vegetables and fruits.

7. Daily chemical industry:

It is used for soap, soap, detergent, washing powder, hand sanitizer, etc. after clothes are polluted by blood stains, milk, fruit juice, soy sauce, grease, etc., if ordinary detergent is used, it is generally difficult to eliminate these stains. If protease is added to the detergent, sweat stains and blood stains can be easily removed, with strong decontamination, sterilization and safety.

8. Cosmetics industry:

Papain acts on the aging cuticle of human skin to promote its decomposition, degradation and removal, so as to achieve the effect of rejuvenating the skin and promoting cell growth. Papain hydrolysate forms a layer of amino acid derivative film on the surface of the skin to keep the skin moist and smooth; Papain is easy to form complexes with copper ions in melanin that forms color spots, so as to reduce the formation of melanin and remove melanin from color spots. Moreover, the tripeptide hydrolyzed by papain can directly inhibit the tyrosine activity of melanin and eliminate the effect of free radicals, so as to achieve the effect of whitening and speckle removal

9. In addition, toothpaste, mouthwash, tooth powder, etc. can be added to clean the mouth, remove tartar and dental calculus, cooperate with other solvents to make a cleaning disinfectant for contact lenses and the recovery of photosensitive film silver, etc.

Vitality:

Definition of enzyme activity: ultraviolet spectrophotometry: under the determination conditions (37 ± 0.2 ℃; pH value 7.0), when the absorbance of trichloroacetic acid soluble matter released from casein hydrolysis per minute at 275nm wavelength is equivalent to that of 1 μ g tyrosine, the amount of enzyme required is an activity unit, expressed in U / G.
