Pig collagen Chinese Synonyms: pig collagen; collagen; collagen (bovine Achilles tendon); I collagen; scale collagen English name: Collagen Synonyms: CELLAGEN (TM) BEADS; CELLAGEN (TM) SOLUTION AC-3; CELLAGEN (TM) SOLUTION AC-5; CELLAGEN (TM) SOLUTION EMEM; CELLAGEN (TM) SOLUTION PC-3; CELLAGEN (TM) SOLUTION PC-5; CELLAGEN (TM) SOLUTION T-IV; CELLAGEN ( TM) SOLUTION WITH DMEM CAS Number: 9064-67-9 Formula: C4H6N2O3R2 (C7H9N2O2R) n Molecular Weight:. 0 EINECS No.: 232-697-4 water: ≤8% relative molecular weight 500-20000 basic protein content of about 3000: ≥ 90% ash content: ≤2% of sulfur dioxide: ≤50mg / kg peroxide: ≤10mg / kg water insoluble: ≤0.1% PH: 4-7 chrome: ≤2.0mg / KG arsenic: ≤1.0mg / KG Heavy Metal: ≤ 1000cfu / g total number of colonies: ≤1000cfu / g Coliform: ≤30cfu / g Pathogens: not detected Packing: 15KG kraft paper bags many judge the quality of collagen through some way to compare the appearance, which is not very Science can only be a simple reference, credible. 1, the color of each product, there will be a natural color, the growth cycle of each product is not the same, harvest time is not the same, there will be a change in color, so the color is not reliable. If you want the product color uniform, very simple, bleach! Regular newspaper reports, smoked white sulfur, hydrogen peroxide bleaching, etc., are food safety issues. If the product color white enough, credible it is a question mark? As a natural product extracted from the color change is definitely yes, pale white, yellow, etc., natural products can not be a standard color. If the color of each batch of products are the same white, would think doubt, but most consumers prefer clean white, which also resulted in manufacturers will find ways to solve turns white, so the natural essence does not exist . The most important is the product after dissolving in water, an aqueous solution of the product is transparent, there is no suspension, no precipitation of impurities, is a state. After the dissolution of collagen, there will be changes in color, this is normal. 2, smell the smell of the product is mentioned in many of the criteria. Instead, some of the more reliable, as we all know, there is fishy fish, beef cattle smell, each animal has its own unique flavor. Bone collagen from the skin of different animals to extract, will have the taste of the animals themselves, but the extraction process removes fat, horny and other impurities, this relatively light taste, is relatively small. The sensitivity of each person's sense of smell is not the same, and finally feel the taste out there will be differences, in general, the taste is definitely yes, even close to tasteless, but also a taste. If there is no taste, but doubtful. If the smell is particularly large, with special emphasis, especially red, it certainly did not deal with the product. When consumers buy collagen products, must be considered: sources of raw materials, technology, purity, color, taste, clarity, molecular weight, ash and other indicators, it is comprehensive, can not just look at one indicator, of course, price is the primary consideration a. Concluded four selection criteria: a collagen molecular weight standards between 1500-3000 Dalton molecular weight range of the best in this most active collagen, after use absorption effect is the best. Molecular weight is too easy to be absorbed by the body, is too small to affect the results of instability. Try to choose a standard two food-grade collagen protein collagen have injections, cosmetic grade (mainly for moisture) and food-grade, the difference between them is that the composition of collagen or collagen peptides. So before selecting collagen sure to ask. Try to choose a standard three no additives pure collagen product oral collagen products, some manufacturers in order to increase the taste, add some different additives, such as a variety of different flavors and tastes, and made of collagen to attract consumers with different tastes, In fact, this is a misunderstanding of consumption, additives have been severely restricted by the state, which fully shows its human potential danger. Selection criteria collagen IV collagen sheet and the capsule except tryptophan and cysteine ??rich outer of 18 amino acids, wherein the amino acid to maintain the necessary kind of human growth. Collagen 30% glycine. Proline and hydroxyproline together account for about 25 percent, is the highest protein content of all kinds, alanine, glutamic acid content is relatively high. In general it also contains rare protein proline and hydroxyproline and other proteins hydroxylysine almost non-existent. So collagen is rich in nutrients. Price: 25500 / T
