Food Additive

It is used in medicine, metallurgy, electronics, textile and other industries, as well as pigments and glass colorants used as catalysts, polishing agents, paints and ceramics. Special magnetic iron oxide can be used to manufacture audio tapes and telecommunications equipment.

There are three stereoisomers of tartaric acid: tartaric acid, L-tartaric acid and racemic tartaric acid. Racemic tartaric acid is a mixture of the same amount of dextrosome and levosome whose optical activity counteracts each other. Racemates do not exist in nature and can be synthesized chemically. All kinds of tartaric acid are colorless crystals which are easily soluble in water. Tartaric acid is widely used as an Acidifier in beverages and other foods, similar to citric acid. Tartaric acid and tannin can be used as mordant of acid dyes, as well as in some developing and fixing operations in the photographic industry. Its iron salt is photosensitive, so it can be used to make blueprints. Tartaric acid can complex with many kinds of metal ions and can be used as cleaning agent and polishing agent for metal surface. Potassium and sodium tartrate (Rochelle salt) can be used as ferin reagent, medicine, laxative and diuretic, and intermediate of cinchofen. The crystal has piezoelectric properties and can be used in electronic industry. Therefore, this product is mainly used in beverage, candy, bread and gelatin as sour agent, biochemical reagent, racemic resolution agent and pharmaceutical resolution agent.

Ethyl maltol is a safe, non-toxic, widely used, effective and low dosage ideal flavor synergist. It has a significant effect on improving and enhancing the flavor of food, sweetening sweet food and prolonging the storage life of food. It can improve and enhance the flavor of food, sweeten sweet food, and has antibacterial and antiseptic properties, which can extend the storage life of food. It is widely used in tobacco, food, beverage, flavor, fruit wine, daily cosmetics and other products.

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 thickener, stabilizer, gelling agent and binder. It is mainly used in food, medicine, agricultural seed, daily chemical industry, industrial wastewater treatment and other industries.
