Liquid Lactic Acid,Essential Raw Materials For Flavours Production, High Acid Stability

Overview

Lactic acid is an organic acid. It has a molecular formula CH3CH(OH)COOH. It is white in the solid state and it is miscible with water. When in the dissolved state, it forms a colorless solution. Production includes both artificial synthesis as well as natural sources. Lactic acid is an alpha-hydroxy acid (AHA) due to the presence of a hydroxyl group adjacent to the carboxyl group. It is used as a synthetic intermediate in many organic synthesis industries and in various biochemical industries. The conjugate base of lactic acid is called lactate.

In solution, it can ionize by loss of a proton to produce the lactate ion CH3CH(OH)CO2. Compared to acetic acid, its pKa is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group.

Lactic acid is chiral, consisting of two enantiomers. One is known as l-lactic acid, (S)-lactic acid, or (+)-lactic acid, and the other, its mirror image, is d-lactic acid, (R)-lactic acid, or (−)-lactic acid. A mixture of the two in equal amounts is called dl-lactic acid, or racemic lactic acid. Lactic acid is hygroscopic. dl-Lactic acid is miscible with water and with ethanol above its melting point, which is about 16 to 18 °C. d-Lactic acid and l-lactic acid have a higher melting point. Lactic acid produced by fermentation of milk is often racemic, although certain species of bacteria produce solely d-lactic acid[citation needed]. On the other hand, lactic acid produced by anaerobic respiration in animal muscles has the (l) enantiomer and is sometimes called "sarcolactic" acid, from the Greek "sarx" for flesh.

In animals, l-lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase (LDH) in a process of fermentation during normal metabolism and exercise.It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal, which is governed by a number of factors, including monocarboxylate transporters, concentration and isoform of LDH, and oxidative capacity of tissues.The concentration of blood lactate is usually 1–2 mM at rest, but can rise to over 20 mM during intense exertion and as high as 25 mM afterward. In addition to other biological roles, l-lactic acid is the primary endogenous agonist of hydroxycarboxylic acid receptor 1 (HCA1), which is a Gi/o-coupled G protein-coupled receptor (GPCR).

In industry, lactic acid fermentation is performed by lactic acid bacteria, which convert simple carbohydrates such as glucose, sucrose, or galactose to lactic acid. These bacteria can also grow in the mouth; the acid they produce is responsible for the tooth decay known as caries. In medicine, lactate is one of the main components of lactated Ringer's solution and Hartmann's solution. These intravenous fluids consist of sodium and potassium cations along with lactate and chloride anions in solution with distilled water, generally in concentrations isotonic with human blood. It is most commonly used for fluid resuscitation after blood loss due to trauma, surgery, or burns.

Application

Industrial field

1. Electroless nickel plating complexing agent

Lactic acid has a unique complexation constant for nickel. More than 97% of the nickel ions in the electroless nickel plating solution of the lactic acid-nickel ion system are in the complex ion state, and the free nickel ion content is less than 3%. Therefore, lactic acid is commonly used for electroless nickel plating. One of the complexing agents. Compared with other complexing agents, lactic acid has strong stability in the plating solution, which can effectively control the deposition rate to ensure uniform and fine plating and stable plating solution. In addition, it is also very effective for suppressing the precipitation of nickel phosphite generated during the electroless nickel plating operation. Lactic acid has excellent synergistic ability, and can form binary or multi-component complexing agent with various complexing agents such as sodium citrate, malic acid and succinic acid, further satisfying the demand for complexing agent in the electroless nickel plating industry.

2. Paint and coating industry

Lactic acid is used as a pH adjuster and a synthetic agent in various water-based coating bonding systems. Such as: coating of electrodeposited materials. Methyl lactate and butyl lactate are synthetic agents for paints, coatings and resins, and butyl lactate is widely used as a brightener for painting and baking varnishes for automotive home appliances.

3. Tobacco

Lactic acid can maintain the humidity of tobacco, remove impurities in tobacco, change taste, neutralize nicotine nicotine, reduce harmful components and improve tobacco quality. Lactic acid can be used to synthesize L-lactate lactate, used as a flavoring agent for tobacco flavor. It has the function of shielding bitter and astringent taste, leaving a fresh sense of smoking in the mouth; potassium lactate is a commonly used coke-burning improver; magnesium lactate and calcium lactate can also be used as tobacco additives to improve gray gray matter.

4. Cleaning agent

Lactic acid ester is an excellent and safe high-boiling solvent with excellent solubility and unique solubility for grease and polymer soils, and has the best environmental and toxicological properties. A formulation that can be used alone or in addition to a cleaning solvent for degreasing and cleaning of a variety of precision machinery and cleaning prior to surface coating.

5. Tanning and textile industry

In the tanning industry, lactic acid removes the lime and calcium from the leather, making the leather soft and fine, resulting in high-grade leather. In the textile industry, lactic acid is used to treat fibers, making it easy to color, increasing gloss and making the touch soft.

6. Alcohol industry

Ethyl lactate is a colorless volatile liquid with special rum, fruit and creamy aromas. It is widely used as a flavoring agent for white wine and fruit wine.
