Malic acid is an important component of natural fruit juice, which has a higher acidity compared to citric acid (with a 20% stronger acidity than citric acid). However, it has a soft taste (with a higher buffering index), a special aroma, and does not harm the mouth and teeth. It is metabolically beneficial for amino acid absorption and does not accumulate fat. It is a new generation of food acidifiers, known as the "most ideal food acidifier" in the biological and nutritional fields. Since 2013, it has been replacing citric acid in food for the elderly and children.

1. Designed for the purification of laboratory hydrochloric acid, nitric acid, and hydrofluoric acid to reduce the content of metal impurities in the acid. 2. Generally, for an acid with a metal impurity content of 10 ppb, after one purification, the metal impurity content can be reduced to about 0.01 ppb. 3. Meet the extremely low detection limit requirements of ICP-MS and provide laboratory-grade ultrapure acid for demanding analytical applications.
