1,268,081. Enzyme composition; starch conversion syrups. A. E. STALEY MFG. CO. 8 Aug., 1969 [26 Aug., 1968], No. 39803/69. Headings C3H and C3U. An enzyme composition comprises a mixture of diastase, glucoamylase and amylo-1,6-glucosidase having an ability to saccharify starch to a syrup having a minimum dextrose equivalent value of 68%, a minimum fermentable extract of 77% and a maximum dextrose content of 47 %; diastase is defined as an enzyme capable of hydrolysing starch to maltose and higher saccharides, and includes inter alia α-amylase, #-amylase and barley malt. The three enzymes may alternatively be added to the starch sequentially. Diastase containing α- and #- amylase may be obtained from fungi, barley malt or animal sources; α-amylase may also be obtained from bacteria or Aspergillus oryzae; the gluco-amylase must be free from transglucosidase; the α-1,6-glucosidase may be obtained from Aerobacter aerogencs. |
