Abstract：
Meat from dairy goats is less tender than that from meat goats since generally they are of an older age when culled. The objective of this study was to improve the quality of barbecued culled-dairy-goat by using juices (ginger and pineapple) and sodium bicarbonate (SB). The optimum time (30, 60, 90 min) for marinating the goat meat with ginger and pineapple juices was evaluated. Then, the optimum levels of SB (0, 1, 3, 5%) and the optimum marinating procedure for the application of SB was studied. The results showed that the ginger-marinated samples had a lower cooking loss than the pineapple-marinated samples. The optimum time for marinating the samples with plant juices was 60 min indicated by the lower hardness and chewiness as compared to those of the samples marinated with plant juices for 30 and 90 min. The cooking loss and L* values of the marinated samples significantly decreased with increasing concentrations of SB. The lowest hardness were observed in the samples marinated with pineapple juice containing 3% SB and ginger juice containing 5% SB. The samples marinated with pineapple juice for 60 min and then marinated with a barbecue sauce containing 3% SB for 60 min had a lower cooking loss and hardness as well as higher scores for all sensory attributes compared to the non-juice-marinated meat with SB and the ginger-marinated meat. The results indicate that pineapple juice and SB (3%) can improve the quality of culled dairy-goat-meat, and in particular its texture.
