ABSTRAK

 

Kajian ini telah dijalankan untuk menentukan kesan tepung gandum, tepung beras dan tepung sagu pada dua nisbah tepung : air yang berbeza terhadap kelikatan dan parameter pemprosesan produk goreng bersalut. Cecair penyalut telah disediakan dengan mencampurkan tepung gandum, tepung beras dan tepung sagu dengan air pada dua nisbah tepung: air iaitu 1 : 1 dan 1 : 2. Pisang nipah (Musa sapientum) sebagai substrat telah disalut dan digoreng pada suhu 180oC selama 3 minit. Keputusan menunjukkan tepung gandum menghasilkan kelikatan, peratus lekatan salutan dan hasil akhir penggorengan yang tertinggi manakala tepung sagu yang terendah sama ada pada nisbah 1 : 1 ataupun 1: 2 (tepung : air). Terdapat perbezaan yang bererti (p<0.05) bagi peratus kehilangan penggorengan di antara jenis tepung yang berbeza bagi kedua-dua nisbah tersebut. Untuk cecair penyalut dengan nisbah 1:2 (tepung : air), tepung gandum menghasilkan peratusan bagi parameter kehilangan penggorengan yang terendah manakala tepung beras yang tertinggi.

 

Kata kunci: Tepung gandum, tepung beras, tepung sagu, kelikatan, parameter pemprosesan.

 

 

ABSTRACT

 

This study was done to determine the effect of using wheat, rice and sago flour at two different flour: water ratio on the viscosity and processing parameters of battered, fried banana. Batter was prepared by mixing wheat, rice and sago flour with water at two ratios of 1 : 1 and 1 : 2 (flour: water). Banana (Musa sapientum) from the Nipah variety were battered and deep-fat fried at an initial temperature of 180oC for 3 minutes. Results showed that wheat flour batter produced the highest while sago flour batter produced the lowest viscosity, coating pickup and cooked yield for both flour: water ratios. A significant difference (p<0.05) was observed between batters from the different flour types in cooking loss at both flour: water ratio of 1 : 1 and 1 : 2. For batters with a flour: water ratio of 1 : 2, wheat flour batter resulted in the lowest cooking loss while sago flour batter the highest.

 

Keywords: Wheat flour, rice flour, sago flour, viscosity, processing parameters.
