L-alanine
Description
L-Alanine (CAS 56-41-7), also known by its FEMA 3818 designation, is a naturally occurring amino acid produced through fermentation or chemical synthesis for industrial use. It functions as a flavor modifier, pH buffer, and humectant across food, pharmaceutical, and personal care manufacturing.
In food and beverage production, this amino acid enhances savory and sweet flavor profiles and is used to balance taste in soups, sauces, and processed foods. Pharmaceutical formulators incorporate it as a stabilizing excipient in amino acid infusions and oral supplements.
It is also utilized in tablet formulations where buffering capacity is required. In personal care, it acts as a moisturizing agent and mild pH adjuster in skin creams, shampoos, and conditioning treatments. These properties make it a versatile ingredient for diverse formulations.
Sports nutrition and nutraceutical manufacturers use it as a labeled amino acid ingredient in powders, capsules, and functional beverages. Its high solubility and stability make it ideal for liquid and dry mix applications across the health and wellness sector.
The product is supplied as a white crystalline powder. Standard grades available for procurement include USP, BP, Ph.Eur., and food-grade (FCC), ensuring compliance with international safety and quality requirements.
The EP and AJI97 standards are also recognized in food and supplement markets. Bulk quantities are available for industrial procurement, with smaller packaging options for specialty formulators needing precise measurements for R&D projects.
