Product Description
L-Alanine is a non-essential, non-polar amino acid that serves as a fundamental building block in protein synthesis. It is classified as an α-amino acid and exists naturally in its L-isomer form, which is biologically active. This white crystalline powder is highly soluble in water and exhibits excellent stability under standard conditions. L-Alanine is produced through microbial fermentation or enzymatic processes, ensuring high purity (typically ≥98.5%) and compliance with international standards such as USP, EP, and FCC.
Key Features:
High bioavailability and biocompatibility. Neutral pH and non-toxic properties.
Suitable for pharmaceutical, food, and industrial applications.
Available in food-grade, pharmaceutical-grade, and technical-grade formulations.

Food & Beverage
Flavor Enhancer: Amplifies umami taste in savory snacks, soups, and seasonings (often paired with nucleotides).
Sweetener Synergist: Reduces bitterness and improves the aftertaste of artificial sweeteners (e.g., aspartame).
Acid Regulator: Balances pH in fermented foods and functional beverages.
Preservative: Extends shelf life in meat products by inhibiting lipid oxidation.
Cosmetics & Personal Care
Moisturizing Agent: Enhances skin hydration in creams, lotions, and serums (1-5% concentration).
pH Adjuster: Stabilizes formulations in shampoos and cleansers. Antioxidant Booster: Supports anti-aging products by promoting collagen synthesis.
