Lactic acid is produced with corn starch or corn stalk as raw material by fermentation refining technology. This product is a viscous liquid with slight acid taste and hygroscopicity. The aqueous solution shows acidic reaction. It can be freely mixed with water, ethanol or ether, and is insoluble in chloroform.
- Meat and poultry products
Lactic acid is widely found in meat. L-sodium lactate can capture a large amount of water in food, thereby preventing the growth of microorganisms, so it is widely used in the meat and poultry food processing industry to extend the shelf life of products. In addition, it enhances and maintains the flavor of the product.
- Vegetable pickled products
Lactic acid can adjust the pH value, thereby preventing the growth of pathogenic microorganisms, preventing the deterioration of radishes, cabbage, cucumbers, onions and other vegetables pickled in brine, ensuring product stability and improving taste. the
- Beverages and brewing
Lactic acid has a mild and moderate acidity and can be used as a sour agent in carefully blended soft drinks and fruit juices. Calcium L-lactate, iron, magnesium, zinc, etc. are used as mineral fortifiers in fruit juices, health drinks and soft drinks. When brewing beer, adding an appropriate amount of lactic acid can not only adjust the pH value to promote saccharification, improve the quality of beer, but also increase the flavor of beer and extend the shelf life. It is used in liquor, sake and fruit wine to adjust pH, prevent the growth of bacteria, enhance sour taste and refreshing taste.
- Dairy products
Lactic acid is an inherent ingredient in dairy products. It has a good taste and is a popular dairy acidulant and pH regulator. Calcium lactate and iron lactate, magnesium, zinc, etc. can be used to fortify milk and beverages with minerals without affecting product flavor and taste, and without protein precipitation. the
- Nutrients and health food
Calcium lactate, magnesium, zinc, and iron can strengthen minerals in sports and health drinks, fruit juices, food, and baby products. They have good water solubility, moderate taste, and are easily absorbed and utilized by the human body. They can improve human body functions and enhance explosive power. the
- Pasta products
Lactic acid, which gives bread its distinctive taste. Lactic acid can also be used to synthesize sodium stearoyl lactylate and calcium stearoyl lactylate, which are used as emulsifiers in bread. As a flour improver, calcium lactate can improve raw materials, improve mechanical resistance, taste, prevent aging, etc. Buffered lactic acid also acts on the protein in the flour, which can make the gluten form a rich mesh structure and make the taste soft; it can also make the noodles elastic, increase the elasticity of the noodles, have a smooth and transparent appearance, and improve the taste. flavor.
Buffered lactic acid is a buffer system formed by mixing lactic acid and sodium lactate in a certain proportion. It has a mild sour taste. After adding buffered lactic acid to candy, it can obtain a lower sugar conversion rate, thereby prolonging the shelf life; powdered lactic acid can make the appearance of fudge Even better, it greatly reduces the occurrence of surface moisture; sodium lactate can reduce sugar conversion and protect the gel; calcium lactate can also be used in chewing gum to stabilize the colloid and adjust pH, and at the same time, because calcium ions can prevent teeth from The loss of minerals can achieve the effect of healthy teeth. the
- Oral care
Sodium lactate is mainly used in the field of medicine as an injection. Its main function is to replenish body fluids and regulate electrolyte balance in the human body to relieve dehydration caused by diarrhea and poisoning caused by diabetes and gastritis.
- Chiral intermediates
Lactic acid can be used as the starting material for the synthesis of chiral medicines. Lactate can be used as an intermediate to participate in the synthesis to improve efficacy. the
- Medical materials
Polylactic acid is a polycondensate of lactic acid. It is hydrolyzed into lactic acid in human tissues. Lactic acid is a metabolite of human body, which can be further converted into carbon dioxide and water. Therefore, polylactic acid has good degradability and can be made into various products for different purposes. Medical materials, such as: degradable sutures, internal fixation for fractures, tissue repair materials, and filling materials for diagnosis and treatment of retinal detachment, etc. In addition, because polylactic acid itself is easy to form a film, it can be used as an ideal material for drug delivery, and is widely used in sustained-release/controlled-release systems of pharmaceuticals.
- Mineral fortification
Lactate (calcium, iron, magnesium, zinc, etc.) can be made into tablets or powders because of its high bioabsorption and utilization rate and good taste. It can be used for the deficiency of various minerals. the
- Complexing agent for electroless nickel plating
Lactic acid has a complexing constant for nickel and is one of the commonly used complexing agents for electroless nickel plating. Compared with other complexing agents, lactic acid has strong stability in the plating solution and can control the deposition rate to ensure uniform and fine plating and stable plating solution. Lactic acid has synergistic effect, and can form binary or multi-component complexing agents with various complexing agents such as sodium citrate, malic acid, and succinic acid, and further meet the needs of the electroless nickel plating industry for complexing agents. the
- Paint and coating industry
Lactic acid can be used as a pH adjuster and synthetic agent in the bonding system of water-based coatings. Such as: coating of electrodeposition. Methyl lactate and butyl lactate are synthetic agents for paints, coatings, and resins. As a brightener, butyl lactate is widely used in spray paints and baking varnishes for automobiles and home appliances. the
Lactic acid can maintain the humidity of tobacco, remove impurities in tobacco, change the taste, and neutralize nicotine and nicotine, reduce harmful ingredients to the human body, and improve the quality of tobacco; lactic acid can be used to synthesize L-menthyl lactate, used as a flavoring agent for tobacco flavors , has the effect of shielding the bitter taste and leaving a fresh feeling in the smoking mouth; potassium lactate is a commonly used burn-reducing agent; magnesium lactate and calcium lactate can also be used as tobacco additives to improve gray matter. the
- Cleaning agent
Lactate is a kind of high boiling point solvent, which has good dissolving power and unique solubility to grease and polymer dirt, and has environmental protection and toxicological characteristics. It can be used alone or can be formulated with cleaning solvents for degreasing and various mechanical cleaning and cleaning before surface coating. the
- Leather and textile industry
In the leather industry, lactic acid can remove the lime and calcium in the leather, making the leather soft and fine, and then making leather. In the textile industry, lactic acid is used to treat fibers to make them easy to color, increase luster, and make them soft to the touch. the
- Wine industry
Ethyl lactate is a colorless volatile liquid with a special aroma of rum, fruit and cream. As an excellent solvent with unique properties, it is widely used as a flavoring agent for liquor and fruit wine.
