Heat-Resistant Lactic Acid is a high-purity organic acid with superior thermal stability and biodegradability. It maintains structural integrity under elevated temperatures, making it ideal for food processing, pharmaceuticals, and industrial applications requiring enhanced heat resistance.
Product Overview
Heat-resistant lactic acid (L(S)-2-hydroxypropanoic acid) is a type of lactic acid with excellent heat tolerance, produced using modern fermentation and refining techniques. The product is a colorless, clear, viscous liquid with a mild acidic taste and hygroscopic properties. It is soluble in water, ethanol, and ether, and is widely used in industries such as food, pharmaceuticals, brewing, and plastics. This lactic acid also has excellent biodegradability and high absorption properties, and is commonly referred to as "muscle lactic acid" in various applications.
