Tannic Acid Powder

What is Tannic acid?

Tannic acid powder is a type of polyphenolic compound that is widely present in plants and has various biological activities such as antibacterial, antiparasitic, antiviral, antioxidant, anti-inflammatory, and immune regulation. Therefore, tannins are the main research direction for natural alternatives to antibiotics in feed. Plant tannins have strong protein affinity and have been successfully used in ruminant nutrition to reduce rumen protein degradation, thereby improving protein utilization and animal production efficiency. Adding tannic acid-containing feeds to ruminant diets also has three important functions, namely controlling bloating, intestinal parasites and pathogenic bacteria in animals. Tannins have traditionally been considered an “anti-nutritional factor” in monogastric animals and poultry, but recent research shows that when applied appropriately, tannins improve the gut microbial ecosystem and enhance gut health, thereby increasing production performance. The suitability of phytotannins as alternatives to antibiotics in feed depends on many factors that contribute to the large variability in their observed effects.

Tannic acid is the condensation product of gallic acid and glucose. Tannic acid is a polyphenolic natural product. The polyphenolic structure can be combined or complexed with polysaccharides, proteins, alkaloids and metal ions, and can capture free radicals and has antioxidant functions. The wide range of applications has led more and more researchers to explore the mechanism of action of tannins. Recently, researchers have discovered a new mechanism of action of tannic acid, which can effectively inhibit ferroptosis, laying a theoretical foundation for further drug development of tannic acid.

What are the benefits?

1. Anti-wrinkle effect

As we age, the collagen in the skin cross-links with each other and the structure becomes stronger and less elastic. Elastin is the most important fibrous protein that maintains skin elasticity. The decrease or denaturation of its content is the main reason for the formation of skin wrinkles. Tannins can promote cell metabolism, maintain the vitality of elastin, and keep the skin healthy, shiny and elastic.

2. Resist UV rays

Tannin is a natural substance that has strong absorption in the ultraviolet light area. Tannin is called a "UV filter", with an absorption rate of over 98% of ultraviolet rays. It is effective against sunburn dermatitis and various stains. It has obvious defensive effect.

3. Whitening effect

The color of skin is mainly determined by the content of melanin. Tannin can reduce and decolorize melanin, and can also effectively remove reactive oxygen species. Therefore, tannin has a comprehensive whitening effect.

4. Moisturizing effect

The appearance of healthy skin depends on the moisture content of the stratum corneum. Long-term dehydration can lead to rough skin and the formation of wrinkles. The molecular structure of tannin contains a large number of hydrophilic groups - phenolic hydroxyl groups. This makes it easy to absorb moisture in the air, so it has a moisturizing effect.

5. Antiseptic effect

Tannin has obvious inhibitory ability to a variety of bacteria, fungi and microorganisms. At the same inhibitory concentration, it will not affect the growth and development of human cells. Tannins also have unique antioxidant properties, which can effectively resist biological oxidation and scavenge reactive oxygen species. Therefore, tannins can effectively inhibit bacteria and have health and antiseptic effects.

Anti-nutritional effects

(1) Bind to protein

①Reduce palatability

On the one hand, tannic acid tastes bitter and has poor palatability; on the other hand, once tannic acid is ingested, it will bind to the mucin on the surface of the tongue, causing the temporary failure of the "hydration boundary/mixed lubrication" system mediated by oral mucin, and thus Increase the friction coefficient on the tongue surface and reduce the palatability of the feed, thereby reducing animal feed intake.

②Reduce protein utilization

The protein and tannic acid in the feed combine with each other, reducing the utilization rate of protein in the feed.

③Reduce digestive enzyme activity

Tannic acid enters the gastrointestinal tract and binds to proteins, reducing the activity of various digestive enzymes in the gastrointestinal tract of livestock and poultry, thereby affecting the normal digestion of proteins in the gastrointestinal tract.

④Inhibit transport proteins

Tannic acid has an inhibitory effect on the intestinal brush border amino acid transporter, thereby inhibiting amino acid absorption.

(2) Complex with mineral elements

Tannic Acid Powder can also react with mineral elements to reduce the utilization of nutrients in feed.

Lee et al. (2010, 2009) found that tannic acid can reduce the iron content in the blood of piglets, and as the tannic acid content in the feed increases, the iron in the blood tends to further decrease.

Application direction

1. Used as food antioxidant.

2. Used as viscosity reducer and fluid loss reducer for water-based drilling fluids.

3. Used for leather tanning.

4. Used in skin care products for sun protection and skin brightening.

5. It is clinically used to treat local bleeding, and can be used in toothpaste to protect teeth and prevent gum bleeding.

6. Used as a clarifying agent for low-alcohol wine and fruit wine.

7. Used for chromium-free passivation of zinc plating layer.
