Introduction
a-anhydrous glucose ester is colorless or white crystalline powder, odorless and sweet. It is mainly used as a nutritional sweetener.
biological activity
Alpha-D-Glucose is the main energy source for living organisms. It is an intermediate in glycolysis and sugar metabolism synthesis.
Production method
The aqueous sugar solution obtained by partial hydrolysis of edible corn starch with food grade acid and/or enzyme is purified and concentrated. Due to the different degree of hydrolysis, the amount of D-glucose contained can vary greatly. Those made of corn starch are called "corn syrup".
