Raw Material Analysis


Bovine Colostrum: A Native Nutritional Complex, Concentrated Essence. There are differences in the content of some functional components and nutrients between bovine colostrum and mature milk (regular cow's milk). The total protein content in bovine colostrum is more than four times that of mature milk, and immunoglobulin can be over 200 times higher, with the most significant difference being in IgG content, while IgA is about 50-150 times that of mature milk. Additionally, lactoferrin in bovine colostrum can reach over 200 times that of mature milk, lactoperoxidase can be more than three times, and lysozyme can be about ten times higher. The differences in minerals and vitamins are not significant for some, but for others, calcium is about 2-4 times, zinc about 2-12 times, vitamin D about 2-4 times, vitamin B2 about 3 times, vitamin B12 over 8 times, and vitamin E over 48 times. Bovine colostrum: A Native Nutritional Complex. Bovine colostrum is an important commercial source of colostrum, similar to well-known superfoods like turmeric and chia seeds, as it is a natural native nutritional complex, and no single component can fully represent it. Bovine colostrum contains more than 250 types of native nutrients, including immunoglobulins, antimicrobial peptides, growth factors, cytokines, oligosaccharides, etc. These components play different roles, making bovine colostrum potentially beneficial for immunity, gut health, bones, skin, and more. N-Acetylneuraminic Acid: N-Acetylneuraminic acid (also known as sialic acid), abbreviated as SA, NANA, Neu5Ac, CAS No.: 131-48-6, molecular formula: C11H19NO9, molecular weight: 309.27. The main natural sources of N-acetylneuraminic acid are bird's nest and breast milk. In nature, the high content of N-acetylneuraminic acid in bird's nest is also a standard for classifying its grade. Bird's nest is a traditional high-grade tonic, and when we mention bird's nest, we think of beauty, longevity, and its effects come from N-acetylneuraminic acid. When we talk about bird's nest, we are actually referring to sialic acid. On May 31, 2017, the National Health and Family Planning Commission included SA in the new food raw material directory. In April 2020, our company became the third in the country to obtain production licensing approval for N-acetylneuraminic acid. The product can be applied in: maternal and infant formula, dietary nutritional supplements, functional foods, antiviral drugs, and cosmetics.
