Process for preparing glucans having a cyclic structure

摘要

The present invention provides glucans and derivatives thereof which are useful as raw materials in the starch processing industries, food and drink compositions, food additive compositions, and starch substitutes for biodegradable plastics, and processes for preparing the same. Particularly, it provides glucans and derivatives thereof having excellent properties such as higher solubility in water than conventional starches, lower viscosity and the glucans are not subject to retrogradation which is observed in conventional starches, and which are capable of preventing the retrogradation of starches.
