L-Alanine Food Grade High Purity Powder | Flavor Enhancer & Food Additive Raw Material

1. Product Introduction

L-Alanine (CAS: 56-41-7) is one of the most versatile and widely applied functional amino acids in the global food industry. It appears as white crystalline powder with excellent water solubility, pure mild sweet taste and no strange odor, which is a clean-label compliant nutritional supplement and flavor modifier.

Global food manufacturers, beverage brands and condiment factories frequently purchase this raw material. It integrates six powerful functions: nutrition boosting, sour correction, sweetener optimization, off-flavor elimination, anti-oxidation and shelf life extension, suitable for bakery, drinks, sauces, brewing and health supplement formulas.

3. Core Functional Advantages

1. Natural Flavor Enhancement to Smooth Overall Taste

L-Alanine boosts sweet and fresh notes of beverages, pastries and sauces to fix thin flavor issues. It optimizes formula taste with low cost, perfectly matching high-end clean label demands.

2. Eliminate Artificial Sweetener Off-Tastes & Cut Formula Cost

It masks metallic and bitter aftertaste of stevia, cyclamate and saccharin, delivers longer lasting natural sweetness and reduces dosage of expensive sweeteners. It is also a key raw material for high-intensity sweetener Alitame.

3. Neutralize Sharp Sour Taste of Organic Acids

It softens irritating sourness of citric acid, tartaric acid, fumaric acid and acetic acid, creating natural fruity sourness for snacks and beverages, widely adopted by European and American snack factories.

4. Anti-Oxidation & Shelf Life Extension to Reduce Production Waste

It effectively inhibits oxidation of oil, mayonnaise and fermented sauces, avoids flavor deterioration and extends shelf life, cutting manufacturers’ waste loss.

5. Improve Wine Taste & Stabilize Liquor Flavor

Added to beer, sparkling wine and low-alcohol drinks, it removes yeast odor, prevents liquor aging and delivers mellow, smooth taste with stable flavor during long-term storage.

4. Main Global Industrial Application Fields

1. Functional Drinks & Dairy Products

Standard additive for energy drinks, sports beverages, fruit tea, carbonated drinks and dairy goods. 0.1%~1% addition raises protein absorption rate and relieves fatigue, highly popular in global healthy beverage market.

2. Bakery & Desserts

Used in bread, ice pastries and desserts to raise nutritional value, soften mouthfeel and enrich natural sweet aroma.

3. Pickles & Fermented Condiments

Add 5%-10% L-Alanine (based on salt weight) to soy sauce and pickled food to accelerate flavor penetration, shorten pickling cycle, remove fermented odd tastes and strengthen sauce aroma layers.

4. Compound Sweeteners & Sugar-Free Food

Special modifier for low-sugar, sugar-free meal replacements and candies to balance defects of artificial sweeteners and deliver natural taste.

5. Pharmaceutical & Biochemical Intermediates

Raw material for amino acid infusion, nutritional medicine, cell culture and liver function testing. It is also used to synthesize Vitamin B6, calcium pantothenate and other fine chemical products.

5. Stable Physicochemical Properties

L-Alanine has high decomposition temperature at 297℃, maintains stable performance under high-temperature industrial processing. It features high optical purity with consistent color and content across batches. Stable physical property ensures no caking or deterioration during long-distance sea transportation and long-term storage.

As the most abundant non-essential amino acid in human blood, it can be directly absorbed by cells and complies with global food additive safety standards.
