Product Introduction

Vitamin B1 (VB1), also known as thiamine (or thiamin) or antineuritic vitamin, is one of the earliest purified water-soluble B-complex vitamins.
Thiamine is synthesized by fungi, microorganisms, and plants; animals and humans must obtain it from their diet.
It is mainly found in the outer layers and germ of seeds, such as rice bran and wheat bran, and is also abundant in yeast.

Thiamine is composed of a pyrimidine ring and a thiazole ring.
The common forms are thiamine hydrochloride and thiamine mononitrate. Thiamine hydrochloride is primarily used in pharmaceutical and food additive applications, while thiamine mononitrate is more commonly used in feed additives.

Thiamine commonly appears as its hydrochloride salt with the molecular formula C₁₂H₁₇ClN₄OS·HCl and molecular weight of 337.29.
It is a white crystalline powder with a slight characteristic odor and bitter taste, and is deliquescent. It has a melting point of 248℃, is freely soluble in water, slightly soluble in alcohol, and insoluble in ether and benzene.

Product Function & Application
Function:
1. Core Physiological Functions
Thiamine combines with adenosine triphosphate (ATP) to form thiamine pyrophosphate (TPP) , also known as cocarboxylase, which is an essential coenzyme in carbohydrate metabolism. Its key functions include:
- Energy Metabolism: Serves as an essential cofactor for five enzymes involved in glucose, amino acid, and lipid metabolism-34-35. Thiamine helps the body's cells convert food into energy.
- Maintains Normal Nervous System Function: Essential for nerve impulse transmission.
- Maintains Normal Heart Function: Plays an important role in myocardial function.
- Maintains Normal Gastrointestinal Function: Promotes gastrointestinal motility and increases appetite.
- Inhibits Cholinesterase Activity: Deficiency leads to increased cholinesterase activity, accelerated acetylcholine hydrolysis, and impaired nerve impulse transmission.
2. Deficiency Diseases
Thiamine deficiency can lead to:
Beriberi: Divided into dry beriberi (primarily neurological symptoms) and wet beriberi (primarily cardiovascular symptoms).
Wernicke-Korsakoff Syndrome: Commonly seen in alcoholics and malnourished individuals.
Early symptoms include: fatigue, irritability, poor memory, loss of appetite, sleep disturbances, abdominal discomfort, and weight loss-
Digestive disorders, neuritis, etc.
3. Safety
Thiamine is a water-soluble vitamin. Excessive intake is generally not a concern as excess thiamine is excreted in urine-. Thiamine has limited storage in the body and a short half-life, requiring continuous dietary supply.
Application:
-
Food Industry (Nutritional Fortifier)
Thiamine can be used as a nutritional supplement (nutrient fortifier) in various food products:
Grain products: white rice, wheat flour, bread, noodles.
Condiments: soy sauce.
Dairy products: dairy products, margarine.
Baked goods: pastries, biscuits.
Beverages: soft drinks, powdered beverages.
Infant foods, convenience foods, puffed foods, senior foods, etc.
- Pharmaceutical Industry
Treatment of thiamine deficiency and beriberi.
Treatment of Wernicke's encephalopathy.
Adjunctive treatment for indigestion, neuritis, etc.
Injections for patients requiring rapid restoration of thiamine.
- Feed Additive
Used as a feed additive for all animal species.
Maintains normal nerve conduction and proper function of the heart and digestive system in livestock and poultry.
Deficiency leads to carbohydrate metabolism disorders and decreased appetite.
- Other Applications
Industrial manufacturing: petroleum industry, manufacturing, batteries, precision castings, etc.
Can be used as a food ingredient in processed food formulations.
