A branched α-glucan, which is formed by glucose molecules and is characterized by methylation analysis as follows: (1) the ratio between 2,3,6-trimethyl-1,4,5-triacetyl-glucitol and 2, 3,4-Trimethyl-1,5,6-triacetyl-glucitol is in the range of 1: 0.6 to 1: 4; (2) The 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 more in the partially methylated glucitol acetates; (3) The content of 2,4,6-trimethyl-1,3,5-triacetyl-glucitol is 0.5% or more, but less than 10% in partially methylated glucitol acetates; and (4) the content of 2,4-dimethyl-1,3,5,6-tetraacetyl-glucitol is 0.5% or more in partially methylated glucitol acetates. |
