L-Aspartic Acid Zinc Salt (CAS 36393-20-1), also known as Zinc L-Aspartate, is an amino acid chelate that combines zinc with L-aspartic acid to improve zinc bioavailability and absorption. As a food-grade zinc fortifier, it delivers elemental zinc along with L-aspartic acid, supporting nutritional supplementation in functional foods, beverages, and dietary supplements. With assay ≥99% and compliance with food additive standards, it is suitable for bakery, dairy, beverage, and nutraceutical applications.
