Abstract:
A SOLVENT EXTRACTION PROCESS FOR FRACTIONATING AN AMYLOSE POWDER HAVING A RANGE OF D.P. VALUES INTO A FRACTION HAVING D.P. VALUES ABOVE 50 AND A FRACTION HAVING D.P. VALUES BELOW 50. SOLVENTS WHICH MAY BE USED ARE WARM WATER, AN AQUEOUS 3-6 CARBON ALKANOL, AQUEOUS ACETONE AND AN AQUEOUS SOLUTION OF A FATTY ACID.
Abstract:
THE INVENTION DEALS WITH A METHOD OF PREPARATION OF AMYLOSE WHICH GIVES AN EXCELLENT SUBSTRATE FOR THE QUANTITATIVE ANALYSIS OF AMYLASE, ESPECIALLY FOR THAT IN BLOOD SERUM. THE OUTLINE OF THE PREPARATION PROCESS IS THAT THE GELATINIZED STARCH OR WAXY-STARCH IS CONVERTED INTO LINEAR CHAIN AMYLOSES BY THE AID OF ALPHA-1,6-GLUCOSIDASE, AND THROUGH PRECIPITATION AND FRACTIONATION THE LINEAR CHAIN AMYLOSE, WHICH IS WATER-SOLUBLE AND VERY SENSITIVE TO AMYLASE, IS SEPARATED FROM THE ONLY SLIGTLY SOLUBLE MACROMOLECULES AND OLIGOSACCHARIDES.
Abstract:
Purified macromolecular amyloses are prepared by debranching the branched fraction present in starch, namely amylopectin, with the employment of alpha-1,6-glucosidases after gelatinizing the starch by heating, freezing the resultant, thawing the frozen product, heating the thawed product to a temperature lower than 70*C, eluting the low molecular amyloses, and then removing the retrograded starch thus formed in order to purify the macromolecular amyloses.
Abstract:
THE PRESENT INVENTION RELATES TO A PROCESS FOR THE PRODUCTION OF VARIOUS FOODS AND DRINKS UTILIZING PREVIOUSLY UNKNOWN SWEETENERS, COMPRISING THE ADDITION OF SUCROSE OR SUGARS CONTAINING FRUCTOSE TO STARCH HYDROLYZATE, SUBJECTING THE MIXTURE TO ACTIONS OF BACILLUS MACERANS AMYLADE, BACTERIAL SACCHALOGENIC -A-AMYLASE (B.S.A), FUNGAL A - AMYLASES, OR PANCREAS AMYLASE, PRODUCING OLIGOSACCHARIDE SYRUPS CONTAINING TRANSFERRED FRACTOSE AND THEN UTILIZING THE SYRUPS AS A MATERIAL FOR THE PRODUCTION OF THE SAID FOODS AND DRINKS.
Abstract:
A process for producing starch sugars involves subjecting starch slurries to the action of acids or combinations of various amylases and converting dextrins, produced by saccharification of starch, into straight-chain malt dextrins using an Alpha -1,6glucosidase that decomposes the Alpha -1,6-glucoside bonds, or the branching bonds of starch, thereby facilitating the saccharifying reaction and, at the same time, converting the oligosaccharides or dextrins into straight-chain malt dextrins or oligosaccharides, and thereby preparing a starch sugar solution of a composition different from that of ordinary starch syrups and which is less viscous, and then finishing the liquor easily by spray drying to a powdery product.
