머루주 박의 급여가 돈육 등심의 품질에 미치는 영향

This study was carried out to investigate the feeding effect of wild grape wine by-products on pork qualities. The chemical composition, volatile basic nitrogen, thiobarbituric acid reactive substances and pH were not significantly different between control and wild grape pork, but the cholesterol and roast loss of wild grape polk. were lower than those of the control, and 1l1e salt soluble protein extractability of the control was lower than that of the wild grape pork. The Hunter's $a^{\ast}$ and $b^{\ast}$ value of wild grape polk. meat were higher than the control, the $a^{\ast}$ value of wild grape polk. meat was higher than the control, but the $L^{\ast}$ value of meat and fat were not significantly different between control and wild grape pork. The cohesiveness, gumminess and chewiness of control(respectively $66.2\%$ 428kg and 189g) were higher than wild grape polk. (respectively $61.4\%$ 357 kg and 154 g). The total amino acid composition of polk. were not significantly different between control and wild grape wine, The glutamic acid, leucine, arginine and aspartic acid were major amino acids in control and wild grape pork. The arachidonic acid $(C_{20:4})$, EPA $(C_{20:5})$ and DHA $(C_{22:6})$ of wild grape polk. were higher than those of the control. The taste (p
