The
Characteristics and Uses： |
1.The
food-grade Glycine is mainly used as nutritional supplement and food
additive:
It is used as a flavoring or sweetness because it
is sweet. In combination with sodium glutamate, DL-alanine, or
citric acid, it can be used in alcoholic beverage; as a acid
corrector or buffer for the composition of wine and soft beverage;
as an additive for the making of salted vegetables and sweet jams;
as an additive for the making of sauce, vinegar and fruit juice, in
order to improve the flavor and taste of food, to retain its
original color and to provide a source of sweet;
It can be
used as an antiseptic agent for fish flakes and peanut jams, because
it can inhibit the reproduction of bacillus subtilis and E.coil;
Glycine consists of amino and hydroxyl ions and therefore
has strong buffering effects. It can play a buffering role in the
taste of edible salt and vinegar;
It plays a certain role in
metal chelation and antioxidation. Therefore, it can be used as a
stabilizer for, cream, cheese, margarine, fast cooked noodles, wheat
flour and pig lard;
It can be used as an inductor in feed
additive because it is weet;
It can be used as an inductor
in feed additives because it is sweet;
It can be used in
food processing, brewing process, meat processing ingredient as well
as in saccharin sodium in order to remove bitterness.
2.The
medical-grade Glycine:
It is mainly used in amino acid
injection solution as nutritional infusion. It can be used to
patients who have digestive malfunction, or long consumptive
diseases, and urgently need nutritional supplement, including those
who have gastroenterotomia, severe traumatic infection, severe
burns, cancer, or liver-kidney failure, It also can be used as a
nutritional supplement before or after surgical operations;
It can be used as a supplemental medicine to treat
myasthenia progressive and pseudo hypertrophic muscular dystrophy;
The solution containing 30% Glycine and 70% medical calcium
carbonate, may be taken orally to treat neural hyperchlorthydria and
gastric ulcer hyperchlorhydria.
It can be used as a buffer
for Aureomycin, as a raw material L-Dopa foe treating Parkinson’s
disease, as a raw material for synthesis of B6 amino acids including
threonine, the intermediates of imidazoleacetic acid;
It can
be used as a stabilizer for Vitamin C;
It can be used in the
research on the metabolism of amino acids by medical organisms or on
a biochemical basis.
3.The industrial-grade Glycine can be
used as a solvent for removing CO2 in the fertilizer industry, as an
additive to the electroplating solution, as a pH regulator, and as
an intermediate of pesticides, e.g.a key raw material for herbicide
glyphosate. |
