Glycine has a unique sweet taste, can ease acid, alkaline taste, masking the bitter taste of saccharin in food and enhance the sweetness. If an excessive amount of human intake of glycine, not only can not be absorbed by the body, and will break the balance of the body’s absorption of amino acids affect the absorption of other amino acids, leading to nutrient imbalances and affect health. Glycine as the main raw materials to produce milk drinks, normal growth and development of young people and children can easily adversely affected.(Supplies:http://www.lubonchem.com/)
