Abstract
This study was conducted to investigate the changes of pH, TBA, meat color and sensory evaluation on duck meat fed supplemental Bamboo vinegar during storage period at 4$^{\circ}C$ . Experiment animals (five-wk-old, Cherry Valley F$_1$, 100 chicks) were randomly assigned in four treatment groups. Treatments were control, 1%, 2% and 4% based on Bamboo vinegar addition. There was no PH difference in breast meat between groups on day 1 of storage, while pH of bamboo vinegar supplemented group was sustained hi호 after 3 days. TBA values of Bamboo vinegar treated groups were significantly lower than control group (P<0.05) and were steady change during storage. The color value in lightness no difference between groups during the storage. The control was significantly increased in 6 d and 9 d, while the bamboo vinegar treated groups no difference during storage. The redness and yellowness in bamboo vinegar treatment were decreased in 3 d and 9 d storage. The decrease in yellowness was outstandingly observed in bamboo vinegar 1% and 2% treatment (P<0.05). The odor in terms of sensory evaluation was improved by supplemental bamboo vinegar treatment. The significant differences were observed on 1 d, 3 d and 6 d storage (P<0.05). The appearance of sensory evaluation of supplemental Bamboo vinegar treated groups (P<0.05) was significantly different in 1 d and 3 d storage. The results of this study indicate that the supplemental Bamboo vinegar 1% and 2% may improve meat quality during storage period in duck meat.
