Abstract
A sugar syrup is prepared by saccharifying a liquefied starch hydrolyzate at a pH of about 4 to about 5.5 and a temperature above 55.degree. C. with a heat stable, aciduric, pullulanase obtained from rice and an .alpha.-1,4 carbohydrase. The pullulanase employed is substantially free of maltase and transglucosidase activity. In one embodiment, a dextrose syrup is prepared by saccharifying a thinned starch hydrolyzate with glucoamylase and the rice pullulanase. Maltose syrup is prepared using the rice pullulanase and a maltogenic enzyme.
