Drying characteristics and some properties of spouted bed driedn semi-refined carrageenan

摘要

The study was focused on the evaluation of spouted bed drying as a method for achieving dried carrageenan gels suitable for grinding, in order to obtain a final product in the form of a powder. Cubes formed from semi-refined carrageenan gels K12, K73, and their blends with carrageenan 92S (iota) were dried in a spouted bed at three temperatures: 60, 100, and 150 degrees C. Functional properties of the dried product were assessed in terms of density (bulk, apparent, and true), water activity, col
