摘要: The present teachings provide direct conversion of granular starch into a soluble sugar composition comprising a high, very high, and/or ultra high maltose content. The method involves contacting an aqueous slurry of granular starch with an enzyme composition comprising an appropriate ratio of an alpha-amylase and a maltogenic enzyme to produce a soluble starch substrate that is enzymatically converted to a sugar composition containing higher maltose. The process may use more than one temperature to achieve the same. 1

摘要: The present teachings provide a method for making a high glucose syrup at a low temperature. In some embodiments, the syrup contains reduced reversion reaction products. The method comprises contacting a starch substrate at a temperature below the starch gelatinization temperature with an enzyme blend comprising a high dose of alpha-amylase and a low dose of glucoamylase. In some embodiments, a blend of two glucoamylases is employed. In some embodiments, a debranching enzyme such as a pullulanase is employed. In some embodiments, the enzymes are staged by adding at different times, or at different temperatures. The present teachings provide for high glucose syrups with fewer reversion products, and allow for higher starch solubilization.

摘要: Provided herein are compositions and methods related to the direct conversion of the starch in a ground or fractionated grain into a fermentable sugar feedstock capable of serving as a carbon source for the industrial production of one or more products by a fermenting organism. Such conversions may be performed at temperatures at or below the initial gelatinization temperature of the starch present in the grain and may utilize one or more isolatable endogenous enzymes present in certain unrefined grains.
