Material Characteristics
Form & Handling Characteristics
Two characteristics from the product information are especially relevant when evaluating L-Aspartic Acid for formulation.
L-Form Identity
This material is the L-enantiomer of aspartic acid. Purchasing and quality specifications should identify L-Aspartic Acid where this specific chemical form is required.
Limited Water Solubility
L-Aspartic Acid is slightly soluble in water. For liquid or reconstituted products, dissolution should be evaluated under the intended formulation and processing conditions.
Aplicações
L-Aspartic Acid Applications
L-Aspartic Acid is used across food and nutrition formulations as well as amino acid ingredient systems. Application suitability depends on the required grade and finished-product specification.
Food & Beverage Formulation
Applicable to food formulation projects where L-Aspartic Acid is used for flavor-related or nutritional purposes.
Nutrition Products
Used in nutritional and amino acid products, including powder blends and other finished dosage formats.
Misturas de aminoácidos
Can be incorporated into multi-amino-acid formulations at the level defined by the finished product.
