초록
The objective of this study was to evaluate the effect of dietary lycopene supplementation on meat quality in Longissimus Muscle of Korean native pigs. Meat samples were obtained from pigs which had been fed with finishing pig diets containing basal diets(C), 200 ppm lycopene (T1), 400 ppm lycopene (T2), and 800 ppm lycopene(T3). Longissimus muslce pH was not influenced by feeding lycopene. Total microbial counts of treatments were significantly lower than those of control at 0 day of storage (p<0.05). Counts of lactic acid bacteria and coliform of T2 and T3 were significantly lower than those of control and T1 at 0 day of storage(p<0.05). Regardless of packaging, microbial counts increased as the storage period increased(p<0.05). While water-holding capacity (WHC) values of the treatments were lower than those of control, cooking losses values of treatments were higher than those of control (p<0.05). Therefore, it can be concluded that Korean native pigs fed lycopene supplemented diets affect the microbial counts and meat quality (volatile basic nitrogen, WHC and cooking loss) compared with conventional ones. These results may show a fundamental data on production of Korean native pork.
