Food antioxidants are food additives that can prevent or delay food oxidation and deterioration, improve food stability and prolong storage life. Oxidation will not only make the oil in the food deteriorates, but also make the food fade, discolor and destroy vitamins, so as to reduce the sensory quality and nutritional value of food, and even produce harmful substances, causing food poisoning. We provide natural food antioxidants, including tea polyphenols, rosemary extract, natural vitamin E, etc. Synthetic antioxidants include propyl gallate, tert-butylhydroquinone, butylhydroxyanisole, dibutyl hydroxytoluene, isoascorbic acid and so on.

SUGAR ESTERS are non-ionic surfactants, which are synthesized by esterification of sucrose and fatty acids. Since sucrose contains 8 -- OH groups, all kinds of products from single ester to octyl ester can be formed by esterification. It can be subdivided into mono-fatty acid ester, difatty acid ester and trifatty acid ester. With its non-toxic, easy biodegradation and good surface properties, it is widely used in food, medicine, daily chemical, biological engineering enzyme preparation, oil...
Porpylene glycol fatty acid ester is obtained by esterification reaction from propylene glycol and fatty acid with potassium carbonate, quicklime and p-toluenesulfonic acid as catalyst heated for 6-l0h at 120-180 ℃.The resulting product is a mixture of mono-ester and diester.Propylene glycol mono-fatty acid ester can be obtained by molecular distillation. Propylene glycol fatty acid ester has good foaming and emulsifying properties, its foaming ability depends on the content of single ester,...
This instant ginger powder is extracted from small yellow ginger, using water extraction process to extract high purity small molecular ginger essence. It contains no solvent and additives, removes ineffective substances, retains the original flavor and keeps spicy feeling stronger. This product is yellow fine powder, over 80 mesh, water soluble, no pigment, natural, safe, mild. It can be used in processed food, health care products, cosmetics, daily chemical products. Instead of fresh...
