The present invention provides a process for preparing low D.E. starch hydrolysates and low D.E. conversion syrup products which are both liquid and solid. Starch is treated with bacterial alpha amylase to a D.E. less than 15. The hydrolytic action of the amylase is terminated by heat treatment and the resulting hydrolysate is further converted with bacterial alpha amylase to a D.E. between about 5 and about 20. From the resulting hydrolysate product is obtained a non-hazing syrup which is substantially completely water soluble.

Low D.E. starch conversion products

A process for the production of dextrose-containing syrups wherein a deionized starch hydrolyzate is treated with glucoamylase immobilized on porous alumina.

Method using glucoamylase immobilized on porous alumina

Process for the production of xylose (dextrose) isomerase by means of a mutant strain of Streptomyces that proliferates in a culture medium that may be free of xylose. The xylose (dextrose) isomerase enzyme is therefore constitutive rather than induced.
