    The main application of Lactic Acid
    • In foods such as dressings, pickles, baked goods, and dairy products, lactic acid provides tangy flavor and acidity that enhances taste.
    • Lactic acid in drinks plays an essential role in balancing taste and ensuring freshness.
    • In fermented dairy products such as yogurt, and cream, bacterial cultures produce lactic acid to create the characteristic sour taste and texture. It preserves food while increasing its probiotic content.
    • Lactic acid is used to balance and maintain the acidity in skin care products such as cleansers, lotions and peels.
    • Lactic acid in pharmaceuticals acts as an excipient to regulate drug solubility and pH balance.
    • Industrially, lactic acid is converted to ethyl lactate, which is used as a biodegradable, non-toxic solvent in paint strippers, textile coatings, and food processing equipment cleaners.
