Glycine (also known as aminoethanoic acid) is the simplest amino acid in structure. Its chemical formula is C₂H₅NO₂. It is a white crystalline powder, odorless, with a special sweet taste, and is soluble in water. It is a non-essential amino acid for the human body and is also the only natural amino acid without a chiral center. It plays a dual role in biological systems as both a raw material for protein synthesis and an inhibitory neurotransmitter. Glycine is recognized as a safe food additive (GB 2760, with the function of flavor enhancer), possessing unique characteristics such as distinctly sweet taste, pH regulation, metal ion complexation, and inhibition of microbial growth. Therefore, it is widely used in food flavoring, medicine and nutrition, pesticide synthesis, feed, and the cosmetics industry.

The Application of Glycine

I. Food and Condiment Industry
Enhancing flavor and flavor improvement agents: Glycine has a unique sweet and refreshing taste (with a sweetness approximately 0.8 times that of sucrose), which can effectively alleviate the salty taste of salt and the sour taste of vinegar, making the overall flavor more harmonious; at the same time, it can mask the aftertaste of bitter substances such as saccharin, enhancing the taste. According to the GB 2760 standard of China, the maximum usage amount in seasonings (excluding salt and salt substitutes, and spices) is 1.0 g/kg.
Food preservatives and antioxidants: Glycine has an inhibitory effect on common spoilage bacteria such as Bacillus subtilis and Escherichia coli. It is commonly used as a preservative in food products like fish paste and peanut butter, with an addition rate typically ranging from 1% to 2%. By chelating metal ions, it delays fat oxidation and can significantly extend the shelf life when added to butter, cheese, and artificial cream. When mixed with glucose and added to baked goods, it can effectively stabilize lard and extend the shelf life.
Nutritional supplements: Used to increase the amino acid content of food, enhance nutritional value, suitable for preparing nutritional fortified foods and specific dietary products. According to GB 2760 regulations, they can be added to cooked meat products (maximum usage 3.0 g/kg), fruit and vegetable juice beverages, and plant protein beverages (maximum usage 1.0 g/kg) and others.
II. Medicine and Nutritional Health Care
Amino acid infusions and total nutrition preparations: Glycine is the core formulation component of various amino acid infusions and total nutrition preparations, providing patients with nitrogen sources and nutritional support.
Auxiliary treatment for digestive system diseases: Glycine solution can be used to treat excessive stomach acid and chronic enteritis; when used in combination with aspirin, it can reduce its irritation to the gastric mucosa; when added to oral rehydration salts (ORS), it can enhance the absorption of sodium and water, and is used to treat diarrhea.
Liver protection and nerve protection: Studies have shown that glycine can protect the liver from alcohol-induced liver damage and ischemia-reperfusion injury by inhibiting the activation of Kupffer cells and reducing inflammatory responses; at the same time, as an inhibitory neurotransmitter in the central nervous system, it is used to regulate signal transmission in the spinal cord and brainstem.
Health supplements and dietary supplements: Used to improve sleep quality, alleviate symptoms of benign prostatic hyperplasia, and as sports nutrition supplements to enhance physical endurance and recovery ability.
III. Agriculture and Feed
Herbicide raw material: Glycine is the key raw material for producing glyphosate, the most widely used herbicide in the world.
Feed Additives: As nutritional additives, they supplement amino acids in poultry, livestock and pet feed, promoting animal growth and improving feed conversion rate; at the same time, they have antioxidant functions, which help extend the shelf life of the feed.
IV. Industry and Cosmetics
Chemical intermediates: Used for the production of various fine chemicals such as cephalosporin antibiotics, imidazoleacetic acid, and surfactants.
Electroplating and buffer reagents: In the electroplating industry, they are used as additives to improve the quality of the coating; in the laboratory, they are used to prepare Tris-glycine electrophoresis buffer, complexometric titration indicators, etc.
Cosmetics raw materials: Used for preparing hair dyes, high-end detergents, cosmetics and personal cleaning products, to achieve pH regulation, enhanced stability or improved skin sensation effects.
