Application:
DL-Malic Acid (CAS: 617-48-1) is primarily used in the food and beverage industry often contributing to the sour taste of fruits. It has been widely used as a Food Additives and Acidulant. DL-Malic Acid (CAS: 617-48-1) is responsible for the refreshing taste you get when you bite into certain sour fruits like apples, grapes, and cherries. Its smooth, lasting tartness makes it the perfect food additive. When malic acid food grade ingredients are blended with other acids, sugars, sweeteners, and seasonings, it can result in highly pleasing flavors, allow for extended flavors, and even act as a food acidity regulator. Uses also include as raw materials for pharmaceuticals, cosmetics, dental lotions, metal cleaners, buffers, coagulants in textile industry, and fluorescent whitening agents for polyester fibers. This ingredient's commercial uses are wide-ranging and occur from the food and beverage industry to personal care products and beyond. As a result, malic acid is one of the most in-demand food additives on the market today. The palate of malic acid is close to natural juice and has a natural fragrance. Compared with citric acid, malic acid has greater acidity (sour taste is 20% stronger than citric acid), lower heat output, softer taste (higher buffering coefficient) and longer detention time. The corrosion damage is weak, and the wear of the tooth enamel is small, which does not damage the mouth and teeth. Malic acid is a new generation of food acidity, which is known as &ldquo in the biological and nutritional fields; the most ideal food acidity agent ” It is widely used in many kinds of foods, such as wine, beverage, jam, chewing gum and so on. It has become the third place food sour agent after citric acid and lactic acid. It is one of the most widely used organic acids in the world food industry.
