Malic acid is white crystal or crystalline powder with high water absorbability. Soluble in water (363 g/l at 20° C), ethanol (86.60 g/100g at 20° C), methanol (197.22 g/100g at 20° C), acetone (60.66 g/100g at 20° C), and ether (2.70 g/100g at 20° C). Compared with citric acid, malic acid has higher acidity (20 percent higher), lower quantity of heat, softer taste, higher buffering factor and more lasting time; however, it is not so corrosive as citric acid that leads to series enamel wear, and it is harmless to mouth cavity and teeth.  As a new generation of food acidity regulator, malic acid is known as best food acidity regulator in biological and nutritional fields. It is widely used in foods such as wines, beverages, fruit juices and chewing gums. It is not only the third food acidity regulator coming after citric acid and lactic acid, but also one of the biggest and most promising  organic acids in food industry across the current world.

- Compared with citric acid, malic acid has higher acidity (20 percent higher)
- Lower quantity of heat, softer taste, higher buffering factor and more lasting time
