Product Description

Polyglutamic acid introduction
Polyglutamic acid( γ- PGA, also known as natto gum or polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer obtained through microbial fermentation. γ- PGA polyglutamic acid is a viscous substance first discovered in natto - fermented beans. γ- PGA polyglutamic acid is a special anionic natural polymer composed of α- Amino group( α- Domino and γ- Carboxyl group( γ- Chemicalbook homopolyimide formed by amide linkage between caboxyls γ- The molecular weight of PGA ranges from 50000 to 2 million Daltons. Its moisturizing and water locking effect is 500 times that of hyaluronic acid. Mainly used for moisturizing, whitening, antibacterial, and promoting skin health. Polyglutamic acid was first discovered to exist in the highly viscous drawing of Japanese natto food (fermented soybeans), abbreviated as γ- PGA is a biodegradable polymer of high molecular weight amino acids produced by liquid fermentation of natural natto bacteria and glutamic acid.

The application scope of polyglutamic acid:
The application of this product in food can be used as a food additive to promote nutrient absorption and mask bitter taste; Can be used as a food antifreeze, preservative, thickener, and astringent, green and healthy.

The application in cosmetics can serve as a water retaining agent, which is 3-5 times that of hyaluronic acid. It has the ability to moisturize the skin's stratum corneum, increase the natural moisturizing factors in the skin's keratinocytes, improve the skin's self moisturizing ability, form a protective film on the skin surface, increase skin elasticity, and its elasticity effect is better than collagen. It enhances the skin's antioxidant ability, reduces UV damage to the skin, and inhibits the formation of melanin, ultimately achieving the effects of moisturizing, beauty, and skincare; Adding it to hair care can repair damaged hair follicles, prevent hair splitting, and have a certain relieving effect on hair loss γ- Polyglutamic acid forms a protective film on the surface of the scalp to prevent water loss, dry scalp, and reduce the production of dandruff.

In the field of medicine, it can serve as a drug carrier and play an important role in drug sustained release.
Product features:
Non toxic and biodegradable to human body and environment, environmentally friendly; Water solubility, can obtain odorless, clean, and transparent solutions; The hydrogel with excellent performance in the later stage of easy crosslinking formation; Can be made into sodium, calcium, magnesium, and hydrogen types
Application on agriculture:
γ- Polyglutamic acid γ- PGA can be used as a nutrient for increasing plant yield
1. γ- Polyglutamic acid γ- PGA Hydrogel and γ- PGA has strong hydrophilicity and water retention ability when submerged in the soil, a thin film is formed on the surface of the plant root hairs, which not only has the function of protecting the root hairs, but also serves as the best transportation platform for intimate contact between nutrients, water, and root hairs in the soil. It can effectively improve the dissolution, storage, transportation, and absorption of fertilizers. Prevent the precipitation of sulfate, phosphate, oxalate and metal elements, enabling crops to more effectively absorb phosphorus, calcium, magnesium, and trace elements in the soil. Promote the development of crop roots and enhance disease resistance.
2.γ- Polyglutamic acid γ- PGA Hydrogel and γ- PGA Balanced Soil pH.
It has excellent buffering ability for acid and alkali, which can effectively balance the soil pH value and avoid the acidic soil caused by long-term use of chemical fertilizers.
3.γ- Polyglutamic acid γ- PGA Hydrogel and γ- PGA can combine to precipitate toxic heavy metals.It has excellent chelating effects on toxic heavy metals such as Pb+2, Cu+2, Cd+2, Cr+3, Al+3, AS+4, etc.
4.γ- Polyglutamic acid γ- PGA Hydrogel and γ- PGA can enhance plant disease resistance and stress resistance, integrate plant nutrition and water active components in soil, and enhance resistance to symptoms caused by soil borne plant pathogens.
5.Promote increased production
It can rapidly increase the production of agricultural products such as tea, fruits, and vegetables, with an average yield of 10-20%.
Product efficacy:
Super strong water retention and moisturizing ability.
Polyglutamic acid( γ- PGA molecules contain super hydrophilic carboxylic acid groups, which can fully retain soil moisture, improve the fluffiness and porosity of sticky soil, and improve the fertilizer and water retention performance of sandy soil. Polyglutamic acid has extremely strong water absorption and moisturizing ability, and its use in arid areas has a significant drought resistance and seedling promotion effect.
Enriching nutrients and improving fertilizer utilization efficiency:
Polyglutamic acid( γ- PGA has the characteristics of anionic surfactants and strong adsorption capacity for positively charged nutrients, thereby reducing nutrient leaching and volatilization. While enriching ammonia, phosphorus, and potassium, it also enriches trace nutrients such as calcium, lock, molybdenum, and zinc, meeting the diverse needs of crops, greatly improving the supply capacity of soil nutrients, and improving the utilization rate of nitrogen, phosphorus, and potassium fertilizers.
Long term sustained and controlled release function:
Polyglutamic acid( γ- PGA can absorb and store nutrients. Storing nutrients that are temporarily not used by plants, inhibiting the rapid decomposition and loss of fertilizer components, reducing fertilizer usage, and prolonging the release time of fertilizers in the soil, thereby meeting the nutrient needs of crops in the middle and later stages, avoiding premature aging and de fertilization, reducing the number and amount of topdressing, and basically applying sufficient base fertilizer to grain crops to meet the nutritional needs of the entire growth period.
Improving soil physical and chemical properties:
Polyglutamic acid( γ- PGA contains negatively charged carboxyl groups, which can prevent the production of low solubility salts and precipitation, and can also prevent acidic soil and soil compaction caused by long-term use of chemical fertilizers, creating a favorable growth environment for crops.
Improve crop products and quality:
Using polyglutamic acid( γ- After PGA treatment, the content of vitamins was significantly increased and the content of nitrite was significantly reduced.
Chelated precipitation of heavy metal elements:
Polyglutamic acid( γ- PGA can cause heavy metals to undergo precipitation, chelation and other reactions in soil, and has excellent chelating effects on toxic heavy metals. Reducing the absorption of heavy metals by crops, improving the quality of agricultural products, and also assisting in the remediation of heavy metal contaminated soil.
Adjusting soil pH:
Polyglutamic acid( γ- PGA has excellent buffering ability for acid and alkali, which can effectively balance the soil acid domain value and avoid the acidic soil caused by long-term use of chemical fertilizers.
Improve plant resistance and stress resistance:
Polyglutamic acid( γ- PGA can form a thin film on the surface of plant root hairs to protect them, enhance resistance to plant pathogens transmitted by soil, and improve plant stress resistance.
