ABSTRACT
EFFECT OF CONCENTRATION RATIO NATRIUM ALGINATEGELATINE ON CHARACTERISTIC OF MICROSPHERE
(Prepared By Ionotropic Gelation Methods Aerosolization Technique)
Rico Andre Satriawan
The aim of research was to investigate effect of concentration ratio
natrium alginate-gelatine on characteristic of microsphere. Microsphere
were prepared by ionotropic gelation methods aerosolization technique and
then dried use freeze dryer. Concentration ratio natrium alginate-gelatine,
were used to make microsphere, were F1: (2,25 : 0,25)%, F2: (1,75:0,75)%,
and F3: (1,25:1,25)%. Resulting microsphere were characterised in terms of
characteristic (yield, particle size, and swelling index). The result show that
yield and particle size was increased as natrium alginate concentration
increased on formula. Statistical test show concentration ratio natrium
alginate-gelatine was significant different to yield and particle size.
Swelling index show that peak swelling of microsphere became more
quickly with increased natrium alginate concentration.
