70. The Effect of Grilling and Frying on the Chemical, Sensory and Microbial<br />

Properties of Frozen Frankfurter and Kebab (2003)<br />

Ola Darweesh A1-Maseimi\ University of Jordan<br />

Supervisor: Dr. Basem A1-Abduflah<br />

The effect of grilling and frying at different temperatures and for different times<br />

on the chemical, sensory and microbial properties of frankfurter and kebab was<br />

assessed. Frankfurter and kebab were stored at -18°C and some tests were carried out<br />

during the storage period. The two products were fried at 150 and 170°C for different<br />

times, and grilled at 95 and 115°C for different times. Significant differences in the<br />

proximate composition of some treatments were observed. The cooking loss for<br />

frankfurter ranged between (6.99-15.06%) and (1 3.65-32.25%) for kebab.<br />

The Aerobic Plate Count (APC) for the raw frankfurter was (3.40 logCFU/g) and<br />

for cooked treatments ranged between 0.89 and 1.73logCFU/g, whereas, APC for<br />

cooked kebab was (2.65-3.25logCFU/g) and for the raw (4.14 logCFU/g). In terms of<br />

thiobarbitunc acid value (TBA)-which indicates the oxidative rancidity of meatcooked<br />

frankfurter showed higher values than that of the raw ones and ranged between<br />

0.75 and 1.16 mg/kg, while for kebab the value ranged between 1.26 and 1.72mg/kg.<br />

In general, for both products, it was observed that with increasing the time of<br />

cooking at any temperature, the moisture content and the APC of the samples<br />

significantly decreased. Whereas the cooking loss arid the TBA number were<br />

significantly increased.<br />

In comparison between grilling and frying, it was found that grilling of<br />

frankfurter and kebab was superior regarding sensory scores, also resulted in a<br />

decreased cooking loss and TBA values indicating oxidative rancidity.<br />
