The food additive Nisin is a kind of polypeptide substance produced by Streptococcus lactis, which consists of 34 amino acid residues and has a molecular weight of about 3500 Da. Because Nisin can inhibit most gram-positive bacteria and has a strong inhibitory effect on the spores of Bacillus, it is widely used in the food industry as a food preservative.

The mechanism of action of Natamycin is to combine with ergosterol and other sterol groups in fungi to inhibit the biosynthesis of ergosterol, thereby distorting the cell membrane, ultimately leading to leakage and cell death. Surface treatment of dough with Natamycin in baked goods can obviously extend shelf life.

L-cysteine is a common amino acid in living organisms. It belongs to the sulfur-containing amino acids. In the presence of nitroprusside, it becomes purple (colored by SH). It is found in many proteins and glutathione. It can form insoluble with Ag+, Hg+, Cu+ and other metal ions. Mercaptide. What i

L-cysteine is an amino acid with physiological functions. It is the only amino acid with a reducing sulfhydryl group (-SH) among more than 20 amino acids that make up proteins. It is widely used in medicine, food additives and cosmetics. In 2002, global demand for cysteine reached 4400-4600 tonnes and the annual growth rate was 2-3%.

L-carnitine has no toxic effects and side effects on the human body. Red meat is the main source of L-carnitine, and the human body can also synthesize it to meet physiological needs. Not a real vitamin, just a vitamin-like substance. It has many physiological functions such as fat oxidation and breakdown, weight loss, anti-fatigue, etc. As a food additive, it is widely used in infant food, diet food, sports nutrition, dietary supplements for middle-aged people and the elderly. Nutritional enhancers for vegetarians and animal feed additives, etc.

L-carnitine is a type of amino acid that promotes the conversion of fat into energy. The pure product is white crystal or white transparent fine powder. It is easily soluble in water, ethanol and methanol, easily soluble in acetone and insoluble in ether, benzene and chloroform. Ethyl acetate. L-carnitine easily absorbs moisture, has good water solubility and water absorption and can withstand high temperatures over 200°C.

Premix feed refers to a mixture that is uniformly stirred by one or more additive raw materials (or monomers) and a carrier or diluent (diluent, thinner), also known as additive premix. The purpose is to facilitate trace amounts of raw materials. Evenly dispersed in a large number of compound feeds. Premixed feeds cannot be fed directly to animals.

fumaric acid is an important organic basic chemical raw material and fine chemical product. Food-grade fumaric acid is mainly used as an acidity regulator, and can also be used as an anti-thermal oxidation aid, a pickling accelerator, an antifungal agent, a preservative, and a spice. What is the agr

citric acid is the largest organic acid produced by biochemical methods in the world. citric acid and salts are one of the pillar products of the fermentation industry and are mainly used in the food industry, such as acidulants, solubilizers, buffers, antioxidants, Deodorant, flavor enhancer, gelling agent, toner, etc.

The chemical formula of aspartame is C14H18N2O5. It is available at room temperature as a white powder. It is a natural functional oligosaccharide with high sweetness, does not melt easily and is caries-free. It can be eaten by diabetics.

The chemical formula of fumaric acid is C4H4O4, a butene-derived carboxylic acid and a colorless, flammable crystal.

citric acid is mainly used as anticoagulant, antacid, flavoring agent, cosmetics, etc. used. About 15% of them are used in the chemical industry. Used as buffer, complexing agent, metal cleaner, stain, gelling agent, toner, etc. used. It is very widely used in industrial fields such as electronics,

aspartame can be added as a sugar substitute because of its extremely low calorie content and its high sweetness to beverages, pharmaceuticals or sugar-free chewing gum. The calorie content of aspartame is about 16.75 kJ/g, and 2.8 mg/dl aspartame can make people feel sweet, so the heat generated by a small amount of aspartame can be ignored.

The sum formula of citric acid is C₆H₈O₇, an important organic acid. It is a colorless crystal, odorless, has a strong acidic taste and is easily soluble in water. It is a natural preservative and food additive.

Sorbitol is easily soluble in water (1g in about 0.45ml water), but not in ethanol and acetic acid. It has fresh sweetness, about half the sweetness of sucrose, and its calorific value is similar to sucrose. When used as a sweetener, it will not cause tooth decay. In the food industry, it is mainly liquid sorbitol, with a content of 69% - 71%. Toxicity tests show that oral overdose may lead to diarrhea and indigestion.

The molecular formula of sorbitol is C6H14O6, which is the main product of photosynthesis of rosaceae plants. It is white hygroscopic powder or crystalline powder, flakes or granules, odorless. Depending on crystallization conditions, the melting point varies between 88 and 102 °C and the relative density is approximately 1.49.

The central nervous system is almost completely dependent on the supply of blood sugar as an energy source, and as soon as blood sugar drops to 80 mg% the phenomenon of glucosuria can occur. In industry, glucose is obtained by hydrolysis of starch, and in the 1960s, a microbial enzymatic process was used to produce glucose.

Glucose​ plays an important role in biology and is an energy source and metabolic intermediate of living cells, i.e. the main energy supplier for living organisms. Plants can produce glucose by photosynthesis. It is widely used in confectionery manufacturing and pharmaceutical fields. Let us read the following words and know more about the glucose.

Glucose is an organic compound with the formula C6H12O6. It is the most widespread and important monosaccharide in nature and a polyhydroxyaldehyde. Pure glucose is a colorless crystal with sweet taste, but not as sweet as sucrose, easily soluble in water, easily soluble in ethanol, insoluble in ether. Natural aqueous glucose solution is optically turned to the right, so belongs to the "dextrose".

Choline is an essential building block in humans and animals and is often referred to as the B vitamin or vitamin B4. Choline chloride is currently the most commonly used and most economical synthetic form of choline. It is a water-soluble vitamin product. It is a component of acetylcholine, lecithin and neurophosphonate in biological tissues. It can save methionine. Polifar Group Limited is dedicated to animal nutrition and can offer you a wide range of feed additives.
