Abstract:
The present invention makes it possible to separate short-chainlength amyloses and long-chain-length amyloses from starches by decomposing and cutting off the Alpha -1,6-glucoside bonds of amylopectin contained in starches by means of an Alpha -1,6glucosidase to form short-chain-length amyloses differing in molecular weight from the naturally occuring amyloses and making use of the difference in molecular weight in those two shorts of amyloses.
Abstract:
Process for producing powdery amyloses having excellent solubility, adsorption and other properties, by hydrolyzing a gelatinized starch solution with isoamylase to a straight-chain amylose solution, slowly cooling said solution thereby forming a crystalline precipitate, and then drying the precipitate by spraying at a low temperature.
Abstract:
A CULTURE MEDIUM, WHICH CONTAINS APPROPRIATE SOURCES OF CARBON AND NITROGEN AND MINERAL MATERIALS, IS INOCULATED WITH PSEUDOMONAS AMLYODERAMOSA (ATCC NO. 21,262) AND THE STRAIN IS CULTURED WITH SHAKING AT ABOUT 30*C. AFTER THE CULTURE, THE CULTURE FLUID OBTAINED IS CENTRIFUGED AND COLD ACETONE IS ADDED TO THE SUPERNATANT FLUID TO PRECIPITATE ISOMYLASE. THE ISOAMYLASE PRECIPITATED IS CENTRIFUGALLY COLLECTED AND DRIED IN VACUO TO YIELD THE ISOAMYLASE IN POWDERY FORM.
Abstract:
According to the present invention, a strain of Aerobacter aerogenes is engaged in a preliminary culture upon a streak culture and then one platinum loop of the resulting seed culture is inoculated into a liquid medium sterilized as usual, which medium contains ammonium salt as a nitrogen source and liquefied starch as a carbon source, and is cultured under the condition of pH 5-8 to produce a large amount of isoamylase.
Abstract:
LIQUIFIED STARCH SOLUTION IS SUBJECTED TO THE ACTION OF AN ALPHA-1,6-GLUCOSIDASE AND SACHARAIFIED. THE RESULTING LINEAR CHAINED MIXED SACCHARIFICATION PRODUCT IS HYDROGENATED TO PRODUCE A NON-DIGESTIVE LINEAR CHAINED SWEETENER MIXTURE OF MALITOL AND MALTOTRIIOL. THE SWEETENER MIXTURE IS ADDED TO VARIOUS FOODS AND DRINKS.
Abstract:
PROCESS FOR THE PRODUCTION OF STARCH SYRUPS WHICH HAVE OLIGO-GLUCOSYL-FRUTOSE AS THEIR MAIN CONSTITUENTS BY SUBJECTING AMYLASE OF BACILLUS MACERANS TO A MIXTURE OF SOLUTIONS OF LIQUEFIED STARCH AND SUCROSE.
Abstract:
PROCESS WHICH COMPRISES PREPARING A HIGH-PURITY MALTOSE SOLUTION BY THE USE OF B-AMYLASE FOR THE AMYLOYLIS AND ALSO A-1,6-GLUCOSIDASE WHICH CAN ELIMINATE FROM STARCH THE A-1,6-GLUCOSIDE BOND THAT HAMPERS THE AMYLOLYSIS BY THE ACTION OF B-AMYLASE, CONCENTRATING THE RESULTING SOLUTION TO A MASSECUITE CONTAINING MALTOSE CRYSTALS, AND THEN SPRAYING THE MASSECUITE IN A DRYING COLUMN TO OBTAIN THE FINAL PRODUCT.
