Product Detail

Usage:

It is mainly used as nutritional supplement and flavoring in food processing industry. It can also be used in the medical industry.
It has a good freshness and can promote the effects of chemical flavorings;
It has a peculiar sweetness and can improve the taste of the artificial sweeteners, improve the sourness of organic acids and the flavor of vinegar;
Its sourness may help salt enter vegetables, improve the quality of salted or sauce-pickled vegetables, cut short the pickling duration and improve the flavor;
It can be used as a corrector or buffer in the composition of wine or soft beverage, can prevent bubble wine from ageing and can decrease the odor of yeast;
Its function of antioxidation can be used in food processing. For instance, it can be used in oils, yolk jam, purified foods, sauce-pickled foods, and bra -pickled foods. It can both protect them from oxidation and improve their flavor;
It can be used as a raw material for Vitamin B6 synthesis and material for the research on metabolism of amino acids by medical organisms or on a biochemical basis.
