Abstract

Syrups and sugars used extensively in the manufacture of food products are obtained by partial or complete hydrolysis of root and cereal starches. Composition of starch hydrolysates varies with the hydrolytic agents employed and the extent of hydrolysis. Acid hydrolysis is a random action and the composition of resultant syrup is dependent on the degree of conversion. On the other hand, enzymatic hydrolysis is a patterned action, the composition of resultant hydrolysate may be varied over a considerable range by the selection of enzyme. The three important amylolytic enzymes viz., a-amylase, p-amylase and amyloglucosidase (glucamylase) show distinctly different pattern of hydrolysis. Individual saccharides present in the hydrolysates contribute not only to the chemical composition of the finished products but also is responsible for its physical properties. The major type of enzyme preparation available for industrial saccharification of starch is obtained from malted barley, bacteria or fungi.
