Applications
1. For Food And Beverage Manufacturing: Malic acid (CAS 6915-15-7) is a natural-tasting acidulant (E296) widely used in beverages, fruit juices, candies, wine and bakery products, delivering smooth, long-lasting sourness and flavor enhancement while balancing sweetness.
2. For Flavor And Confectionery Formulations: With a smooth, apple-like tartness that masks aftertastes, malic acid is ideal for hard candies, sour confections, chewing gum and flavored drinks, supporting consistent flavor profiles in food production.
3. For Cosmetics And Personal Care: Malic acid is used as a pH adjuster in cosmetic and personal care formulations, helping formulators maintain stable product pH in creams, lotions and rinse-off products.
4. For Chemical Intermediates And Industrial Use: Malic acid serves as an intermediate for malate salts and esters, and is used in paints, textiles and industrial cleaning formulations, giving manufacturers a versatile organic acid.
5. Reliable Supply For Global Industry: Supplied in food-grade and industrial-grade crystalline forms with consistent quality, malic acid gives food, beverage, cosmetic and chemical manufacturers a dependable organic acid with stable supply, flexible packaging and professional technical support.
