Abstract

|
|
This study was carried out to investigate the physico-chemical properties of imported beef and Hanwo beef tenderloin steak in proximate composition, pH, myofibril Fragmentation Index (MFI), meat color, cooking loss, rheology and panel test by various cooking methods (grilling, pan-frying, oven-roasting and microwaving). moisture content of microwaving steak was lower than steak by other cooking method, and fat content of microwaving steak was higher than those of other cooking method was showed. In general, the pH values were increased with cooking, but there were no significant differences among pH values by various cooking method. The highest level of MFI in oven-roasting was showed, but no significant difference could be found among various cooking method. L* and b* -values of microwaving and pan-frying were higher than those of grilling and oven-roasting, also a* -value of microwaving was the lowest. Cooking loss was affected by cooking method. Microwaving method resulted in the highest cooking loss. Generally higher value of hardness and brittleness in microwaving than those of other cooking method were showed, and microwaving had the lowest cohesiveness, but there was no significant difference among the elasticity by the cooking method. Grilling, pan-frying and oven-roasting had high score of sensory evaluation, while microwaving had the lowest score in all sensory profile scores.
