Lactic acid is mainly used in food as an acidulant, preservative and flavor enhancer. As an acidulant, it provides a gentle and long-lasting sour taste and is widely used in beverages, jams, candies and brewing; as a natural preservative, it inhibits the growth of harmful bacteria by lowering the pH value, extending the shelf life of products such as pickles, meat products and salad dressings; at the same time, it can improve the texture and flavor of dairy products (yogurt, cheese) and optimize the performance of dough in baking.

Lactic acid, as an alpha-hydroxy acid (AHA), mainly functions in cosmetics by providing moisturization, exfoliation, and pH regulation. It is added to facial cleansers, toners, creams, and body lotions, gently removing aged skin cells on the surface, promoting cell renewal, and improving roughness, fine lines, and uneven skin tone. At the same time, its excellent hygroscopicity helps the skin retain moisture and regulates the product's acidity to adapt to the natural pH environment of the skin.

The most important industrial application of lactic acid is as a monomer for synthesizing polylactic acid (PLA) - a biodegradable and environmentally friendly plastic, which is widely used in the production of disposable tableware, packaging films, 3D printing filaments, and agricultural mulch films, replacing traditional petroleum-based plastics. In addition, derivatives such as ethyl lactate can be used as low-toxicity and biodegradable green solvents for cleaning paints and cleaning in the electronics industry; calcium lactate and sodium lactate, etc., are used as buffers, moisturizers or coagulants.

In agriculture, lactic acid is mainly used as a feed additive and soil conditioner. As a feed additive, it can inhibit harmful bacteria in the intestines of livestock and poultry, promote animal growth and health, and reduce the use of antibiotics; as a soil improvement component, lactic acid helps regulate the soil micro-ecology and promotes the reproduction of beneficial microorganisms; in addition, it can also be used as an auxiliary component in pesticide formulations to enhance the stability of the drug effect.
