Abstract: A PROCESS FOR THE PROPARATION OF STRAIGHT-CHAIN AMYLOSES HAVING MOLECULAR CHAIN LENGTHS OF 20 TO 30 THAT HAVE NEVER BEEN OBTAINABLE HITHERTO. STRAIGHT-CHAIN LOW MOLECULAR WEIGHT AMYLOSES WHEREIN THE MOLECULES HAVE RELATIVELY UNIFORM CHAIN LENGTH ARE OBTAINED BY LIQUEFYING A STARCH SLURRY TO A RELATIVELY LOW EXTENT, RAPIDLY COOLING THE LIQUEFIED SLURRY BEFORE THERE OCCURS A SUBSTANTIAL RETROGRADATION AND SELECTIVELY DECOMPOSING AND CUTTING THE A-1,6-GLUCOSIDE BONDS OF AMYLOPECTIN CONTAINED IN THE STARCH.

Abstract: ACCORDING TO THE PRESENT INVENTION, STARCH IS FIRST LIQUIFIED WITH ACID OR ENZYME, THE PH OF THE RESULTING LIQUIFIED STARCH IS ADJUSTED TO ABOUT 6, THE LIQUIFIED STARCH IS SACCHARIFIED BY THE USE OF BETA-AMYLASE AND ALPHA-1, 6GLUCO-SIDASE OR IN ADDITION ALPHA-AMYLASE DURING THE SACCHARIFYING STEP TO PRODUCE A MALTOSE WITH PURITY OF ABOUT 99%.

Abstract: THE PRODUCTION OF ALPHA-1,6-GLUCOSIDASE BY THE CULTURE OF AN ALPHA-1,6-GLUCOSIDASE PRODUCTIVE BACTERIUM IS CARRIED OUT BY USING A CULTURE MEDIUM CONTAINING STARCH HYDROLYZATE AS A CARBON SOURCE AND A MEMBER SELECTED FROM THE GROUP CONSISTING OF SOYBEAN CAKE HYDEOLYZATE AND A MIXTURE THEREOF WITH AN AMMONIUM SALT AS A NITROGEN SOURCE.
