The role of glycine

Glycine is a relatively special substance. According to different uses, glycine can be divided into food grade glycine, pharmaceutical grade glycine, feed grade glycine, industrial grade glycine, reagent grade glycine, etc. Different types of glycine are used in different industries and occasions, and also require different precautions. Below, we will introduce the classification and specific uses of glycine in detail.

1. Food Grade Glycine

1. Used as a flavoring agent and sweetener, and used in alcoholic beverages in combination with DL-alanine, citric acid, etc.; used as an acid corrector and buffer in the synthesis of sake and refined feed; used as an additive in pickling pickles, sweet sauces, soy sauces, vinegar and fruit juices to improve food flavor, taste, maintain original flavor, provide a source of sweetness, etc.;

2. Used as a preservative for fish paste products, peanut butter, etc., it can inhibit the growth of Bacillus subtilis and Escherichia coli;

3. Using its own amino and carboxyl groups, it can buffer the taste of salt and vinegar;

4. Used as an attractant (attractant) in feed additives;

5. Food brewing, meat processing, and the recipe of refreshing drinks, as well as the debittering agent of saccharin sodium;

6. Used as a stabilizer for cream, cheese, margarine, instant noodles, wheat flour and lard;

7. Used to stabilize vitamin C in food processing;

8. 10% of MSG is glycine;

9. It can be used as a preservative and plays an important role in preserving.

2. Pharmaceutical Grade Glycine

1. Used as a drug in the study of medical microbiology and biochemical amino acid metabolism;

2. Used as a synthetic raw material for chlortetracycline buffer, anti-Parkinson's disease drug L-dopa, vitamin B6, and amino acids such as threonine;

3. Used as amino acid nutrition infusion;

4. Used as raw material of cephalosporin; intermediate of thiamphenicol; intermediate of synthetic imidazole acetic acid, etc.;

5. Used as raw material for cosmetics.

3. Feed Grade Glycine

It is mainly used as an additive and attractant to increase amino acids in feed for poultry, livestock, and especially pets. Used as a hydrolyzed protein additive and as a synergist for hydrolyzed protein.

4. Industrial Grade Glycine

As pesticide intermediates, such as the main raw material for the herbicide glyphosate; electroplating solution additive; PH regulator

5. Reagent Grade Glycine

1. Used in peptide synthesis, as amino acid protection monomer;

2. Used for the preparation of tissue culture medium and the detection of copper, gold and silver;

3. Because glycine is a zwitterion with amino and carboxyl groups, it has strong buffering properties and is often used to prepare buffer solutions.
