FRUCTOSE PRODUCTION BY ENZYMATIC ISOMERIZATION OF GLUCOSE

摘要

IMPROVED FRUCTOSE PRODUCTION Fructose productivity and isomerase activity in immobilized beds or column operations employing isomerases obtained from Bacillus organisms are significantly improved by isomerizing a high solids feed syrup at pH 7.0-7.5 and 55.degree.C to 60.degree.C. Without adding cobalt to the feed streams continuous column operation in excess of 4,000 hours and yielding greater than 3,500 pounds of a 42% fructose syrup for each pound of isomerase can be achieved.
