ABSTRACT
Formulation
models of brick margarine prepared from the interesterified of a fully
hydrogenated palm stearin (POS)
and palm kernel oil (PKO), POS of low iodine values and sunflower oil (SFO) were characterised, physically and chemically. Formulations
with low trans fatty acid content were used in the margarine preparation and
the products were evaluated for 25 days at storage temperatures of 5, 10 and 15oC.
The study had shown that formulations of POS in the form of simple blend with PKO and SFO (sample
900), blend of interesterified fully hydrogenated POS with PKO and SFO (sample 905) and simple blend of fully hydrogenated POS with PKO and SFO (sample 904) could achieve similar fatty acid composition, but
not SFC profile. The results showed
that POS was not only a suitable hard
stock in trans-free brick margarine formulations but provided functional
property in product texture. The formulations, with saturated fatty acid
content < 36% and < 1% trans fatty acid had produced brick margarine with
the desired spreadability at refrigerator temperature (5-15oC).
Keywords:

ABSTRAK
Model
formulasi untuk marjerin berbentuk bata telah disediakan dari stearin sawit (POS) yang telah dihidrogenankan sepenuhnya dan dinteresterifikasikan
dengan minyak isirong sawit (PKO), POS yang rendah nilai iodinnya (IV) dan minyak bunga matahari (SFO). Minyak dan lemak ini telah perincikan daripada segi sifat
kimia dan fizikalnya. Formulasi yang rendah asid lemak transnya telah digunakan
dalam penyediaan dan pembuatan marjerin ini dan hasilnya telah dinilai selama
25 hari pada suhu penyimpanan 5, 10 dan 15oC. Kajian telah
menunjukkan bahawa formulasi adunan mudah POS dengan PKO dan SFO (sampel 900), adunan POS terhidrogenat sepenuhnya dan PKO yang diinterestrifikasi dan SFO (sampel 905) dan adunan mudah POS terhidrogenat sepenuhnya dengan PKO dan SFO (sampel
904) boleh menghasilkan masing-masing komposisi asid lemak (FAC) yang serupa, tetapi tidak serupa daripada segi profil kandungan
lemak pepejal (SFC).
Keputusan ujian produk menunjukkan bahawa POS bukan sahaja sesuai sebagai asas minyak keras dalam formulasi
marjerin berbentuk bata yang bebas trans, tetapi boleh menghasilkan sifat
kefungsian yang diperlukan untuk tekstur marjerin yang baik. Formulasi yang
mengandungi jumlah asid lemak tepu < 36% dan <1% asid lemak trans telah
berjaya digunakan dalam penghasilan marjerin bentuk bata yang mempunyai
keupayaan sapuan yang baik pada suhu peti sejuk (5-15oC).
