레몬과 크랜베리즙이 닭 다리육의 저장품질에 미치는 영향

초록

This study was performed to evaluate the effect of lemon and cranberry juice on meat quality of chicken thighs during cold storage. Experimental groups were chicken thigh meat dipped into distilled water (CON), 1% lemon juice (LJ), 1% cranberry juice (CJ), and a mixture of 0.5% lemon juice and 0.5% cranberry juice (LCJ). The meat quality traits were determined at day 0, 3, 6, and 9 during cold storage at 4℃. The pH value of all treatments was lower than that of the control (P<0.05). Total microorganisms of CJ and LCJ at day 9 was 6.94 and 6.76 log CFU/g, respectively, whereas that of the control was 7.51 log CFU/g. The a* value of CJ and LCJ was higher than that of CON and LJ during storage (P<0.05), whereas the b* value of LJ, CL, and LCJ was lower than that of CON at day 6 and 9 (P<0.05). Overall acceptability of all treatments was significantly higher than that of CON after day 3. Thiobarbituric acid reactive substances and volatile basic nitrogen values were lower than those of the CON after day 3 (P<0.05). Principle component analysis (PCA) of the aroma pattern of all treatments was closer together, whereas PCA of the CON was scattered with the increase in storage days. This result suggests that dipping the chicken thigh meat into the lemon and cranberry juice could be beneficial to enhance chicken thigh meat quality by retardation of total microbes, lipid oxidation, and protein decomposition.
