Food additives refer to chemically synthesized or natural substances added to food for the purpose of improving food quality, color, aroma, and taste, as well as for the needs of antisepsis and processing technology. Due to the rapid development of the food industry, food additives have become an im

Application of Potassium Sorbate Potassium sorbate, also known as potassium 2,4-hexadienoate, is the potassium salt of sorbic acid, and its molecular formula is C6H7O2K. White to light yellow scale-like crystals, crystal particles or crystal powder, odorless or slightly odorous, easy to absorb moist

Nice to work with you in past months ,thanks for your efforts and time with Polifar in 2022. Trust we can create more business opportunities by keeping close communication. Now we are surrounded by Omicron,more and more colleagues and friends were infected ,but this should be the last dark time and

Overview：Calcium propionate is an acid-type food preservative. Under acidic conditions, it produces free propionic acid, which has antibacterial effect. Its antibacterial effect is affected by the pH value of the environment, and the inhibitory effect on mold is the best when the pH value is 5.0. Th

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.

Natamycin is a cream or cream yellow crystalline powder. It is an odorless and tasteless, low-dose and highly safe food preservative. Natamycin is a white to milky white, odourless and tasteless crystalline powder produced by controlled fermentation of Streptomyces nata, usually in the form of an enol structure.

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-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-glycine is a non-essential amino acid whose chemical formula is C2H5NO2. L-glycine is the constituent amino acid of endogenous antioxidant reduced glutathione and is often supplemented by exogenous sources when the body is under severe stress.

L-glycine is a white to cream crystalline powder, odorless and non-toxic. Soluble in water, almost insoluble in ethanol or ether. It is used in pharmaceutical industry, biochemical testing and organic synthesis. It is an amino acid with the simplest structure in the amino acid series and is not essential for the human body. It has both acidic and alkaline functional groups in the molecule. It can be ionized in water and has strong hydrophilicity, but it is an nonpolar amino acid soluble in polar solvents but insoluble in nonpolar solvents, and has a high boiling point and melting point. Adjusting the acidity and alkalinity of the aqueous solution can cause glycine to have different molecular forms.

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.

After eating, it is quickly hydrolyzed into amino acids under the physiological pH conditions of the human body and under the action of α-chymotrypsin. Food additive nisin will not change the normal flora in the human intestinal tract and cause resistance problems like other antibiotics, and will not It has cross-resistance with other antibiotics. It is a natural food preservative with high efficiency, non-toxicity, safety and no side effects.

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.

The molecular formula of potassium sorbate is C6H7O2K, white to light yellow scaly crystals, crystal particles or crystal powder, odorless or slightly odorless, easily absorb moisture, oxidize and decompose, and discolour when exposed to air for extended periods of time. The potassium sorbate is sol

sodium tripolyphosphate is an inorganic substance with the chemical formula Na5P3O10. It is a kind of amorphous water soluble linear polyphosphate. It is widely used in food as a moisture store, quality enhancer, pH regulator and metal chelating agent. What are the chemical properties of sodium trip

sodium benzoate are broad spectrum antimicrobial agents, but their antimicrobial effectiveness depends on the pH value of the food.As the acidity of the medium increases, its bactericidal and bacteriostatic effects are enhanced, but in alkaline medium bactericidal and bacteriostatic effects are lost

sodium benzoate is an organic substance with the chemical formula C7H5NaO2. It is a white granular or crystalline powder, odorless or slightly benzoine smelling, slightly sweet, with astringent taste. The relative molecular mass is 144,12. It is air stable and easily soluble. Water whose aqueous sol

Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic alkali and monochloroacetic acid, with a molecular weight ranging from several thousand to one million. CMC-Na is white fibrous or granular powder, odorless, tasteless, hygroscop

The main function of sodium hexametaphosphate in food is to improve the color, aroma and taste of food, adjust the nutrient composition of food, and extend the shelf life of food. In order to use sodium hexametaphosphate correctly, the quality requirements for sodium hexametaphosphate must be limite
