AKTIVASI KIMIAWI ZEOLIT ALAM UNTUK PEMURNIAN MINYAK IKAN DARI HASIL SAMPING PENEPUNGAN IKAN LEMURU (Sardinella longiceps)
ABSTRACT: Omega-3 fatty acid
has health benefits. Indonesia has some
species of fish that contain this kind of fatty acid such as lemuru. However its utilization as -3 fatty acid source is still limited. Fish oil from lemuru meal processing
has poor quality because of its color and peroxide value, besides its free
fatty acid content. Therefore purification process should be employed to
improve its quality.This research was conducted to elucidate the performance of
natural zeolite in purification of fish oil from lemuru meal processing.
Acitivation of natural zeolite was employed to increase its adsorption
capacity. One technique to activate natrural zeolite was
chemical activation by strong acid (HF, H2SO4, dan HCl). Concentration level of
activated zeolite in purification was also defined. The best result was natural
zeolite activated by HCl and concentration level of 15%. The characteristics of purified lemuru oil
were as followed: absorbance at 430 nm of 0,24, free fatty acid content 4,12,
ω-3 fatty acid content of 20,34%, and peroxide value of 93,6 meq/kg.
