MIKROENKAPSULASI EKSTRAK KAROTEN DARI SPORA KAPANG ONCOM MERAH (Neurospora sp.) DENGAN BAHAN PENYALUT BERBASIS PROTEIN MENGGUNAKAN METODE PENGERINGAN SEMPROT
ABSTRACT: Neurospora sp.
produces intracellular carotenoids pigment stored in its conidia, makes orange
color appearance. Carotene was extracted from spores using acetone-hexane (2:1)
as solvent and virgin coconut oil (VCO) was used to facilitate dilution of
carotene extract. The objective of this research was to obtain the appropriate
type of encapsulant and proportion of core material to obtain good quality
carotene microcapsules for food industry and health purposes.This research was
conducted by randomized block design with 2 factors. The first factor was type
of encapsulant (soy proteinate isolate, sodium caseinate, and whey protein
isolate) and the second factor was proportion of carotene extract (20, 30 and
40% w/w on encapsulant basis).The result of this study showed that microcapsule
with sodium caseinate as encapsulant and 30% proportion of carotene extract had
the highest microencapsulation efficiency, total carotenes, and carotenes
retention values. Whereas microcapsule with soy proteinate isolate and 20% proportion
of carotene extract had the highest water content and microcapsule yield.
Microcapsule with soy proteinate isolate had the highest red and yellow value,
and sodium caseinate had the highest lightness value. The most stable
microcapsule during storage at temperature of 70oC was microcapsule with sodium
caseinate as encapsulant and 20% proportion of carotene extracts.
