Organic Acids

Organic acids are a class of organic molecules containing a carboxyl group (-COOH) functional group. The carboxyl group is the characteristic structure of organic acids, imparting acidic properties to them. Organic acids can be obtained through industrial fermentation, chemical synthesis. The most popular organic acids and their main applications are following:

1. Citric Acid: Widely used in the food and beverage industry as an acidulant, also largely used in pharmaceuticals and detergents industry.

2. Lactic Acid: Commonly used in the food and pharmaceutical industries as an acidulant and pH regulator. It is also the fundamental compound structure unit for the biopolymer polylactic acid(PLA).

3. Malic Acid: Used as an acidulant in the food industry, cosmetics and pharmaceuticals.

4. Oxalic Acid: Primarily used for cleaning, descaling, and in the metallurgical industry.

5. Succinic Acid: Used in cosmetics, food, pharmaceuticals. It is also a very important bio-based four-carbon platform compound.

Typical Case:  Lactic Acid

Technologies can be offered by SmarSEP:
