Pectin-gelatin complex coacervates I: Determinants of microglobule size, morphology, and recovery as water-dispersible powders.

The pectin-gelatin complex coacervate system was evaluated and characterized. The effects of final pH, mixing pH, colloid ratio, and solution concentration were investigated. A recovery procedure yielding microglobules of a controlled and uniform size in dry powder form which were readily revertible in water to a polydispersed suspension was developed. The effect of various conditions and additives on the recovery morphology and size of the microglobules was evaluated.
