💎 1. Product Introduction

Malic Acid is a naturally occurring organic acid widely used in food, beverage, pharmaceutical, and cosmetic industries as an acidity regulator, flavor enhancer, and pH stabilizer.

Chibio Biotech supplies two major types of malic acid:

• L-Malic Acid – the natural biologically active form found in fruits such as apples.

• DL-Malic Acid – a racemic mixture of D- and L-isomers commonly used in food processing.

Both types offer high purity and stable acidity performance, making them ideal for flavor adjustment and formulation stability.
