Other Food Additives

Potassium pyrophosphate is used as emulsifier, tissue modifier and chelating agent in food industry. It is also used as raw material of alkaline water for flour products. It is often used with other condensed phosphates to prevent guano stone from being produced in canned aquatic products and discoloration of canned fruits; Improve the expansion of ice cream, the yield of ham and sausage, and the water holding capacity of ground fish; Improve noodle taste and yield, prevent cheese aging, etc. This product is analytical reagent, hydrogen peroxide stabilizer, electroplating, soap filler.

Acetylated double starch adipate, also known as double denatured glutinous rice powder, is a white to similar white powder, odorless, tasteless, insoluble in cold water and ethanol, and turns reddish brown in the presence of iodine. After the starch is co heated with water, it turns into translucent colloid under certain conditions. Compared with the original starch, its solubility, swelling power and transparency were significantly improved; The aging tendency was significantly reduced and the freezing stability was improved. Acetylated double starch adipate is a widely used chemical modified starch. The product not only has the inherent characteristics of glutinous rice, such as scent, glutinous, sticky, but also has the characteristics of good aging resistance and formability of modified starch, and can be applied to the processing of cakes such as sweet potato and green tea. Acetylated double starch adipate is a composite modified starch obtained by crosslinking and esterification of starch with the mixed anhydride of adipic acid and acetic anhydride and double denaturation of starch. The modified starch has excellent water breaking resistance, good transparency, low temperature stability and acid resistance.

Soft water treatment, daily chemical industry, electroplating phosphating, dyeing fixation, enamel melting and leather degreasing, etc.

Iron is a transition metal element used in coordination chemistry as well as in metallo-organic molecules in pharmaceutical chemistry.

Zinc sulfate is colorless or white orthorhombic crystal or powder at room temperature. It has astringency and is easily soluble in water. The aqueous solution is acidic and slightly soluble in ethanol and glycerol. The pure zinc sulfate does not turn yellow when it is stored in air for a long time, and becomes white powder when it loses water in dry air. Zinc sulfate is mainly used as raw material for making pigment lithopone, lithopone and other zinc compounds. It is also used as nutrient for animals in zinc deficiency, feed additive for animal husbandry, zinc fertilizer for crops (microelement fertilizer), important material for man-made fiber, electrolyte for electrolytic production of metallic zinc, mordant, medical emetic, astringent, fungicide, etc Wood and leather preservatives, etc. It is obtained by the reaction of zinc or zinc oxide with sulfuric acid or by the extraction of sphalerite after roasting in reverberatory furnace.
