  • Publication number: 20130203140
    Abstract: Embodiments of the present disclosure relate to a process for producing isoprenoid precursor molecules and/or isoprenoids from a starch substrate by saccharification and/or fermentation. The saccharification is effectively catalyzed by a glucoamylase at a pH in the range of 5.0 to 8.0. At a pH of 6.0 or above, the glucoamylase possesses at least 50% activity relative to its maximum activity. The saccharification and fermentation may be performed as a simultaneous saccharification and fermentation (SSF) process.

  • Publication number: 20130142903
    Abstract: Rice protein concentrates prepared at low temperature exhibit improved functionality and beneficial physiological benefits, including lowered cholesterol and enhanced lactic acid dehydrogenase activity, without an increase in blood urea nitrogen. The rice protein concentration could be made into a wet dough with comparatively less water than a soy protein concentrate. Use of the rice protein concentrate thus improved processing steps in the formulation of a food article containing the concentrate. The food product advantageously shows an extending shelf life and improved palatable texture.

  • Patent number: 8318157
    Abstract: A maltogenic ?-amylase from Trichoderma reesei (TrAA) and variants thereof in the presence of a glucoamylase are useful in the production of high-glucose syrups from liquefied starch, where the high-glucose syrups produced thereby contain at least about 97% glucose. In this process, TrAA advantageously suppresses the reversion of glucose to malto-oligosaccharides. Expression hosts and encoding nucleic acids useful for producing TrAA and its variants also are provided.

  • Publication number: 20120135108
    Abstract: Methods for the production of substrate, tuber, and grain compositions containing isomalto-oligosaccharides are described. The methods comprise (a) contacting a substrate, tuber or grain containing ungelatinized starch with a maltogenic enzyme and a starch liquefying enzyme to produce maltose; (b) contacting said maltose with a transglucosidic enzyme, wherein said steps (a) and step (b) occur at a temperature less than or at a starch gelatinization temperature; and (c) obtaining a substrate, grain or tuber composition having an enzymatically produced isomalto-oligosaccharide, wherein the oligosaccharide is derived from the grain. The maltogenic enzyme can be either exogenous or endogenous to the grain. The contacting steps can be sequential or concurrent. The present invention also describes flour, oral rehydrating solutions, beer adjuncts, food, feed, beverage additives incorporating the grain compositions made as described.
