摘要： 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 DEG C, eluting the low molecular amyloses, and then removing the retrograded starch thus formed in order to purify the macromolecular amyloses.

摘要： The present invention makes it possible to separate short-chain-length 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 -1,6-glucosidase 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.

摘要： 1357126 Fractionation of amyloses K HAYASHIBARA 26 Aug 1971 [28 Aug 1970] 40101/71 Heading C3U A process for the fractionation of macromolecular amylose and low molecular weight amylose (lower than D.P. 50) involves extracting amylose in the form of fine powder ( - 100 mesh air dried or 20-100 mesh spray dried powder) with a solvent and separating the dissolved low molecular weight amylose solution from the undissolved residual macromolecular amylose. Solvents mentioned are warm water and mixtures of water with C 3 -C 6 alkanols such as propanol and n-butanol, acetone or fatty acids. The amylose material may, for example, be the mixture resulting from the hydrolysis by α-1, 6-glucosidase of corn starch or amylomaize starch. Other starches are also mentioned. The insoluble residual macro-molecular amylose may be re-extracted in powder form after gelatinizing it by heating, drying and pulverizing. Similarly, the solution obtained by the original extraction may be concentrated, dried and pulverized and the resulting powder reextracted.

摘要： To prepare maltopentaose, the following multistage process is used: - preparation of a solution of amylose in an organic solvent, - mixing of the solution with an aqueous acid, - heating of the new solution and mixing thereof with a second organic solvent which is able to remove the first organic solvent from the hydrolysed amylose and allows the formation of a precipitate in the solution thus obtained, and - isolation of the precipitate, as a result of which water-soluble amylose is obtained. Amylase obtained from Bacillus licheniformis is then added to the soluble amylose and a fourth solution is thus formed, the fourth solution is incubated, the amylase is deactivated and the solution thus obtained is fractionated and in this way the solution is obtained which is rich in maltopentaose. Maltopentaose is a polysaccharide which is useful as a substrate in diagnostic serum analyses.
