Pectin-based microspheres: a preformulatory study

Ann N Y Acad Sci. 2001 Nov:944:160-79.

Abstract

This paper reports on (a) the production of pectin microspheres and (b) the influence of different experimental parameters and ionic crosslinking on morphological and dimensional characteristics of pectin microspheres. Morphological and dimensional characteristics of pectin were analyzed as a function of the type of pectin, the dispersing phase, the stirring speed, and the emulsifying agent. Crosslinking by calcium chloride and the encapsulation of antibiotics (i.e., metronidazol and tetracycline) gave particles morphologically similar to empty particles but with slower swelling kinetic.
