1.2 Product Introduction

DL-Alanine is an economical amino acid widely used in food, pharmaceutical and feed industries. As a non-essential amino acid for human body, it participates in carbohydrate metabolism with stable biological activity.
It features mild natural sweetness and can improve food flavor with low dosage, showing stable chemical properties under normal storage conditions. As a professional amino acid manufacturer, we can provide complete export documents to meet mass production demands of food factories, pharmaceutical enterprises and feed manufacturers worldwide.

2. Core Advantages for Overseas Buyers

✅ Cost-effective raw material to cut production costs
As a racemic compound without optical rotation, DL-Alanine is more cost-competitive than L-Alanine. It can replace L-Alanine in food seasoning, feed processing and pharmaceutical intermediate synthesis to greatly reduce raw material expenses. It is the preferred bulk amino acid for global condiment manufacturers.

✅ Low dosage brings obvious flavor improvement, less auxiliary materials needed
Its taste threshold is only 0.06%. A small amount can eliminate sour and bitter off-notes in food, reducing the usage of compound additives and lowering overall formula costs.

✅ Multiple grades in stock to match different production standards
We maintain stable stock of food grade, pharmaceutical grade, feed grade and chemical reagent grade DL-Alanine. We accept small trial orders of 100g-1kg and full container bulk orders, with shipments arranged within 48 hours for in-stock items.

✅ Full set of compliance export documents for smooth customs clearance
Each batch is attached with COA and MSDS. We can issue free sales certificates and third-party test reports on demand, satisfying import audit requirements of Europe, America, Southeast Asia, Middle East and Africa.

✅ Free samples & technical formula reference service
Free samples are available for global buyers, customers only need to cover international shipping fees. We provide mature dosage reference schemes for sauces, fruit juices, fermented wine and pharmaceutical synthesis to reduce your R&D trial costs.

✅ Long-term price lock agreement to avoid raw material price fluctuation
Overseas clients with stable long-term cooperation can sign annual supply contracts with fixed unit prices. Our 10,000-ton permanent stock ensures continuous supply all year round without interruption affected by market price volatility.

3. Main Industrial Application Fields of DL-Alanine

3.1 Food Seasoning Industry

Classified as permitted food flavor and nutritional fortifier under national standards, widely supplied to condiment factories, beverage producers, pickled food plants and breweries:

1. Enhance flavor of compound seasonings: Mix with nucleotide flavor enhancers to boost umami taste of soup bases and sauces;
2. Optimize sweet taste: Neutralize bitter aftertaste of artificial sweeteners, widely applied in sugar-free drinks and meal replacement food;
3. Balance sour taste of organic acids: Soften sharp sourness of citric acid, glacial acetic acid and succinic acid. Adding 0.2% in vinegar delivers richer mellow flavor;
4. Pickled food processing: Add 5%-10% based on salt weight to shorten fermentation cycle of pickles and retain natural color of raw materials;
5. Alcoholic beverage production: 0.1%-1.5% addition in fruit wine, sake and fruit juice softens alcohol taste, reduces yeast odor and delays beverage deterioration;
6. Antioxidant preservation for oils: Tiny dosage added in edible oil and salad dressing inhibits lipid oxidation and extends shelf life of food products.

3.2 Pharmaceutical & Biochemical Research

1. Pharmaceutical intermediate: Core raw material for synthesis of Vitamin B6, pantothenic acid and other APIs;
2. In-vitro diagnostic reagent: Key material for liver function test kits to detect alanine transaminase activity;
3. Laboratory biochemical reagent: Used for cell culture and basic biological experiments in universities and biological research institutions.

3.3 Aquatic & Livestock Feed Additive

Serves as nutritional fortifier to supplement essential amino acids for breeding animals. It improves feed palatability, boosts feed intake, optimizes meat quality and reduces breeding losses for livestock and aquatic farming.

4. Export Packaging, Storage & Transportation Specifications

5. Frequently Asked Questions for Overseas Buyers

Q1: How to choose between DL-Alanine and L-Alanine for import? Which one offers better cost performance?

A: DL-Alanine is a racemic mixture with more favorable price, suitable for mass industrial production of food seasoning, feed additives and pharmaceutical intermediates, which makes it the mainstream choice for overseas condiment factories. L-Alanine is mainly used in high-end medical infusion and premium health care products with higher procurement cost. Most food processing enterprises can meet production standards with DL-Alanine to control raw material costs effectively.

Q2: Does food-grade DL-Alanine comply with food import regulations in Europe and America?

A: This product complies with China GB 2760 food additive standard, US GRAS and EU food ingredient access specifications. Complete qualification documents are provided for hassle-free customs clearance worldwide.

Q3: Can we lock the purchase price and get stable long-term supply for bulk orders?

A: Overseas buyers with long-term cooperation can sign annual supply contracts with fixed purchasing prices. Our permanent stock of 10,000 tons ensures stable supply all year long and avoids cost hikes caused by raw material market fluctuations.
