ABSTRAK
Kajian ini dijalankan untuk menentukan kesan hidroksipropil
metil selulosa (HPMC) dan jangka masa penggorengan yang berbeza ke atas
pemindahan eugenol dalam produk nuget ayam bersalut. Tiga kepekatan HPMC
digunakan iaitu 0, 0.75 dan 1.5% serta tiga jangkamasa penggorengan iaitu 210,
240 dan 270 saat. Sampel nuget ayam ditambah 0.5% kandungan eugenol, disalut
dengan kepekatan HPMC yang berbeza dan digoreng pada suhu 180˚C. Di akhir
penggorengan selama 210, 240 dan 270 saat, kandungan eugenol bahagian salutan
nuget meningkat secara signifikan (p<0.05) berbanding sebelum penggorengan.
Untuk setiap jangkamasa penggorengan selama 0, 210 dan 240 s, tiada kesan penggunaan
HPMC yang signifikan didapati ke atas kandungan eugenol dalam salutan. Tetapi
penggorengan selama 270 saat, menunjukkan kandungan eugenol yang lebih tinggi
dengan penggunaan HPMC. Peningkatan jangkamasa penggorengan menghasilkan
penurunan kandungan eugenol dalam substrat pada setiap kepekatan HPMC. Manakala,
peningkatan kepekatan HPMC menghasilkan peningkatan kandungan eugenol dalam
substrat.
Kata kunci: Eugenol;

ABSTRACT
This study was conducted to determine the effects of hydroxypropylmethyl
cellulose (HPMC) and different frying period on the migration of eugenol in
coated fried nuggets. Three HPMC concentrations, 0, 0.75 and 1.5%, along with
three frying periods of 210, 240 and 270 sec were used. Samples of chicken
nuggets were added with 0.5% eugenol, coated with different HPMC concentration
and fried at 180˚C. At the end of 210, 240 and 270 sec of frying, eugenol content in the coating increased
significantly (p<0.05) compared to before frying. For each frying period of 0, 210 and 240 s, no
significant effect of using HPMC on eugenol content in the coating was found.
However, frying for 270 s showed a higher eugenol content when HPMC was used. Increasing
the frying period resulted in a decrease of eugenol content in the substrate
for each HPMC concentration. Increased HPMC concentration resulted in an
increased eugenol content in the substrate.
