Abstract

A method for preparation of microcapsules from hemicellulosic substance comprises - dispersing hemicellulosic substance together with a gaseous medium in a liquid medium comprising water, organic solvent and surfactant so that microbubbles are formed in the liquid medium with the hemicellulosic substance gathered at interface of the microbubbles, and - forming the microcapsules from the dispersed hemicellulosic substance gathered at the interface of the microbubbles and the liquid medium.
