Food grade glycine is mainly used as a nutritional supplement and food additive: sweetness is used as a flavoring agent, sweetener, and used in conjunction with sodium glutamate, DL-alanine, citric acid, etc. in alcoholic beverages for synthesis Alcohol and refreshing beverages are used as sour taste correctors and buffers; additives for pickled vegetables and sweet sauces; additives for soy sauce, vinegar, and fruit juices. The role is to improve the flavor and taste of food, maintain the original color, and provide sweetness source; can be used as cream Additives to cheese to extend its shelf life.
Packaging and transportation
1. Food-grade glycine is packed in 25kg composite kraft paper bag or woven bag, or 900kg and other specifications can be provided according to user requirements.
should be lightly loaded and unloaded to prevent damage to the package; prevent the sun and rain, and cannot be transported with toxic or harmful substances.
Storage and shelf life: In a sealed container, the shelf life is two years in a cool and dry place.
Glycine is one of the 20 members of amino acid series with the simplest structure, also known as aminoacetic acid. It is a non essential amino acid for human body. It has both acidic and basic functional groups in the molecule. It is a strong electrolyte in aqueous solution, has high solubility in strong polar solvent, and is insoluble in non-polar solvent. This product is mainly used in pharmaceutical industry, biochemical test and organic synthesis. For example, it is used as buffer, preparation of tissue culture medium, test of copper, gold and silver, and medically for the treatment of myasthenia gravis and progressive muscle atrophy, gastric acidosis, chronic enteritis, hyperprolinemia in children and other diseases.
