Abstract

Proposed is a process for the production of spherical alginate pellets from drops of alginate solution delivered by a nozzle, the drops being solidified by dropping them into an ionic solution and subsequently removing the pellets and rinsing them. The alginate solution is converted into drops by vibrational stimuli, and the drops subsequently allowed to remain substantially free in the ionic solution until the required degree of solidification has been reached.
