Product Overview

DL-Alanine (CAS 302-72-7) is a racemic amino acid, belonging to the amino acid raw material series. It contains both L-Alanine and D-Alanine enantiomers. This product has good water solubility and stable chemical properties. It is commonly used as a food flavor enhancer and nutritional fortifier. It can improve the taste of food, enhance umami, bring mild sweetness. It is also used in dietary supplements, biochemical culture media and pharmaceutical intermediate synthesis.

Key Characteristics

1.Racemic amino acid structure Contains equal proportions of L-Alanine and D-Alanine, stable physical and chemical properties, not easy to decompose during processing.

2.Excellent water solubility Dissolves rapidly in aqueous systems, suitable for solid powder, liquid beverage and food formulation.

3.Food flavor enhancing property Improves food taste, enhances umami and balances flavor profiles, widely used in food seasoning.

4.High purity & low impurities Strict purification process, low heavy metal content, meets food and nutraceutical safety requirements.

5.Good formula compatibility Compatible with most amino acids and food additives, suitable for various food and supplement production processes.

Main Functions

1.Food taste adjustment & umami enhancement Acts as a flavor modifier, enhances umami and masks unpleasant off-flavors in food formulations.

2.Amino acid nutritional fortification Supplies alanine for human nutrition supplementation, supports normal protein metabolism.

3.Supports energy metabolism Participates in body energy generation and glucose metabolism pathways.

4.Biochemical medium component Serves as nutrition source for microbial and cell culture systems.

5.Raw material for pharmaceutical synthesis Used for preparation of amino acid related pharmaceutical intermediates.

Main Applications

1.Food & Seasoning: Flavor enhancer, taste modifier, used in seasonings, savory food, functional beverages and solid food for umami adjustment.

2.Dietary Supplements & Nutraceuticals Amino acid compound formulas, nutritional powder and sports nutrition products for amino acid fortification.

3.Biotechnology & Laboratory Research Cell culture medium and microbial fermentation medium raw material.

4.Pharmaceutical Industry Amino acid pharmaceutical intermediates and compound amino acid preparations.
