BRANCHED α-GLUCAN, α-GLUCOSYL TRANSFERASE PRODUCING THE SAME, AND PRODUCTION METHOD AND USE THEREOF

Japanese Patent JP2014218677

A

PROBLEM TO BE SOLVED: To provide glucan useful as a water-soluble dietary fiber, and a production method and use thereof.SOLUTION: Branched α-glucan comprises glucose as constituent sugar, and is characterized by methylation analysis as follows: (1) Ratio of 2,3,6-trimethyl-1,4,5-triacetyl-glucitol to 2,3,4-trimethyl-1,5,6-triacetyl-glucitol is in the range of 1:0.6 to 1:4; (2) Total content of 2,3,6-trimethyl-1,4,5-triacetyl-glucitol and 2,3,4-trimethyl-1,5,6-triacetyl-glucitol is 60% or higher in the partially methylated glucitol acetate; (3) Content of 2,4,6-trimethyl-1,3,5-triacetyl-glucitol is 0.5% or higher but less than 10% in the partially methylated glucitol acetate; and (4) Content of 2,4-dimethyl-1,3,5,6-tetraacetyl-glucitol is 0.5% or higher in the partially methylated glucitol acetate. The present invention also provides a novel α-glucosyl transferase which forms the branched α-glucan, and a production method and use thereof.
