Properties and Usage:
Lactic acid is an organic acid with a wide range of sources and excellent performance. It has natural antibacterial and biodegradable properties and is used in many industries such as food, medicine, chemical industry, and agriculture.
1. Food and Beverage Industry
Food Additives: Lactic acid is a natural acidifier and preservative, often used in fermented foods (such as yogurt, kimchi, etc.) to enhance flavor and extend shelf life.
Acidifier: Used in beverages and condiments to adjust pH, enhance taste and extend product shelf life.
Natural preservative: The antibacterial properties of lactic acid can inhibit microbial growth and help preserve food.
2. Medicine and Health
Drug Preparation: Used to prepare drugs such as lactic acid injection, regulate fluid balance, and serve as a sustained-release carrier for drugs.
Skin Care: Lactic acid is used in skin care products such as moisturizers and lotions to help remove dead skin cells and improve skin smoothness and moisture.
3. Chemical Industry and Industry
Bioplastics: Lactic acid is the main raw material for polylactic acid (PLA), which is used to produce biodegradable packaging materials and disposable products, meeting environmental protection requirements.
Cleaners and solvents: Lactic acid is used to make cleaners and solvents. Due to its good solubility and biodegradability, it is widely used in decontamination and cleaning.
4. Agricultural applications
Feed additives: Promote animal digestion and absorption, improve feed conversion rate, and enhance the production efficiency of animal husbandry.
Soil conditioner: Lactic acid is used to adjust soil pH, improve soil structure, and increase crop yield and quality.
5. Other applications
Lactic acid can also be used to adjust pH in water treatment to improve water quality.
Storage conditions: Sealed in plastic drums. Store in a clean and dry place.
Packing: This product is packed in10kg 25kg 50kg Glass bottles packed in wooden cases or sealed in plastic drums, and it can also be customized according to customers' requirements
