Lactic acid is a versatile organic acid that can be used in brewing, medicine, leather, cigarettes, chemicals, food, printing and dyeing. The distribution of lactic acid in Japan is roughly 20% for brewing, 50% for food, 10% for lactic acid derivatives, and 20% for industrial use such as leather. The distribution of uses in our country is also roughly the same. 1. Brewing industry The brewing industry uses about 80% lactic acid. Adding lactic acid can prevent the reproduction of miscellaneous bacteria, promote the development of yeast, prevent the turbidity of the wine and enhance the flavor of the wine, and can also increase the yield of the wine. 2. Food industry The food industry generally uses 50% lactic acid. Mainly used in lactic acid drinks, refreshing drinks, cakes, pickles and sour agents. Lactic acid can make foods slightly acidic without concealing the natural flavor and aroma of fruits and steamed vegetables. Therefore, it is widely used in canned foods such as tomatoes, olives, pickles, and sour cabbage. Kefir beverages made with lactic acid bacteria are also very popular. 3. Pharmaceutical industry Lactic acid can be directly formulated into medicine or made into lactate for use. Oral administration can be used for intestinal disinfection. It can also dissolve protein and keratin, and is particularly sensitive to the corrosion of diseased tissues, so it can be used to treat throat tuberculosis, diphtheria, lupus and other diseases. In addition, it is also used for bactericidal treatment: grouting agent, coating agent, bladder injection, and vaginal cleansing agent. Use the hydrophilic characteristics of lactic acid to combine with insoluble drugs to increase the absorption of drugs and prevent side effects. Lactic acid is also a raw material for making erythromycin icing, so it is widely used in the pharmaceutical industry. 4. Leather industry Generally, the content of lactic acid used in leather is 40%. It has low requirements for the quality of lactic acid. It can be used in dark and odorous. The leather industry mainly uses it to remove lime from tanning, also called deliming. The quality of the leather after deliming with lactic acid is better than other acids. The deashing quality is good, and high-grade leather must be treated with lactic acid. In the production of cigarettes, lactic acid can be used to remove impurities in tobacco and remove the bitter and spicy taste. Therefore, lactic acid treatment can improve the grade of low-grade tobacco. Lactic acid is used as a pH control agent in the production of celluloid coatings; it is used in the wool spinning industry for pre-chromium dyeing of dyes to reduce the chromate content of wool and prevent fiber oxidation; in the post-treatment of silk and rayon, it is used as a pH adjustment It is used for brightening treatment to increase the color of yarn. Pure lactic acid is tasteless, and the product has a slightly similar aroma of cool milk. When the concentration is appropriate, it has a pleasant sour taste. When lactic acid is used as a raw material, it is mostly used as an ingredient in dairy product flavors such as butter, cool milk, butter hard candy, milk, and cheese. The main derivative of lactic acid: calcium stearoyl is used as a food additive. Adding 0.3%-0.5% calcium stearoyl lactate to flour can make bread leaver, increase its volume by 30%-40%, and delay aging. When sodium lactate is used as a flavoring agent, it is used in the production of casein plastic whitener, antifreeze, moisturizer and medicine. Calcium lactate can be used as a nutritional supplement. Ferrous lactate is used for food fortification and medical treatment of iron deficiency anemia. Lactate esters, including methyl ester, ethyl ester, butyl ester, etc. are used as solvents, flavoring agents, etc. Lactic acid, its sodium salt, calcium salt and other derivatives are non-toxic and are safe food additives. Stearoyl lactate is used in emulsifiers and baked foods; sodium lactate is used for intravenous injection; synthetic lactic acid is used instead of natural fermented lactic acid in cheese and other dairy products to acidify and coagulate milk or cream. These three uses have doubled the production of lactic acid in the United States. With the development of the food industry, there is a huge potential market for lactic acid.

It can be used as a food additive and coloring agent. It can also be used as a health care product to treat vitamin A deficiency. In addition, it can also be used as a feed additive.

Copper gluconate is a copper salt of D-gluconic acid that displays a light blue to bluish-green color. It is prepared by the reaction of gluconic acid solutions with cupric oxide or basic cupric carbonate. According to the good manufacturing or feeding practice by the FDA, copper gluconate is used as a nutrient or dietary supplement and is generally recognized as safe for use at a level not exceeding 0.005 percent. Copper Gluconate is the orally bioavailable copper salt of D-gluconic acid. In addition to its roles as an enzyme cofactor for cytochrome C oxidase and superoxide dismutase, copper forms complexes with the thiocarbamate disulfiram (DSF) forming DSF-copper complexes, which enhances the DSF-mediated inhibition of the 26S proteasome; proteasome inhibition may result in inhibition of cellular protein degradation, cessation of cell cycle progression, inhibition of cellular proliferation, and the induction of apoptosis in susceptible tumor cell populations.

Hydroxypropyl Distarch Phosphate, as a thickener, is very suitable for the production of jam, yogurt, oil consumption and other foods, which is stipulated in GB2760-2014; Hpdsp can be used as thickener in all kinds of foods, and can be added appropriately according to production needs

Magnesium stearate has good adhesion and lubricity to skin. It can be used in powder products in cosmetics to improve adhesion and lubricity. Magnesium stearate can be used as heat stabilizer of PVC, and its stability is similar to that of calcium stearate. It can be used in food packaging materials with zinc soap or calcium soap, but it is not widely used.
