KARAKTERISASI DAN SIFAT FISIK SISTEM KOASERVASI GELATIN - GUM AKASIA
ABSTRACT: Complex coacervation
system of gelatin solution of 1% and acacia gum of 1% could be developed for
encapsulation of bio-active materials. The system had been developed to
measured optimum pH of coacervate formation, coaservate recovery, viscosity and
density of the solution sistem for predicting its membran thickness on covering
the bio-active materials. Results showed that using turbidity measurement, pH
of the system could recovery of the coacervate of the sistem was 3,5 and the
dried coacervate recoveri was 81±4%. The mixture of gelatin solution of 1% and
gum acacia solution of 1% were measured for density and viscosity and the
results were 1,0876 ± 0,0045 g/ml and 0,986±0,025 mPa.s, respectively. This
physical characteristics could be used for calculating membran thickness for
certain bio-active material to be coated.
