    Factory Supply Gallnut Extract Tannic Powder Tannic Acid CAS 1401-55-4 Gallotannic Acid

    What  is Tannic Acid/Gallotannic Acid ?

    Tannic acid, also known as tannic acid, is an organic compound with the chemical formula C76H52O46. It is a yellow or brownish yellow powder, and its aqueous solution turns blue black when it meets an iron salt solution. The addition of sodium sulfite can delay the color change. In industry, tannic acid is widely used in tanning leather and manufacturing blue ink. Tannic acid can coagulate proteins. People chemically treat pig and cow hides with tannic acid, which can coagulate the soluble proteins in the hides. So, the raw leather that would have smelled and rotted in a few days turned into beautiful, clean, flexible, and durable leather. This tanning process is called leather tanning.

    Tannic acid is a specific form of tannin, a type of polyp-henol. Its weak acidity (pKa around 6) is due to the numerous p-henol groups in the structure. The chemical formula for commercial tannic acid is often given as C76H52O46, which corresponds with decagalloyl glucose, but in fact it is a mixture of polygalloyl glucoses or polygalloyl quinic acid esters with the number of galloyl moieties per molecule ranging from 2 up to 12 depending on the plant source used to extract the tannic acid.

    Function

    Doesn't decompose in stomach ,sustained release at intestinal tract , improve tannin effect;
    1,It solved the disadvantage of tannin binding with oral mucosal protein and avoided the disadvantage of poor palatability.
    2,Good flexibility, not easy to absorb moisture, conducive to feed processing;
    3,Play the special effects of tannic acid on diarrhea, antimicrobial, antiviral and anti-inflammatory, effectively regulate intestinal flora and improve production performance

    Tannic acid in feed additive can bind and precipitate with mucin of digestive tract, cause the sense of convergence and dryness of rough fold, play a strong convergent effect, regulate intestinal osmotic pressure and relieve diarrhea of piglets.
    In human medicine also used in acute gastroenteritis and various non-bacterial diarrhea and so on.
