Abstract

This study was conducted to investigate the effect of dietary mugwort pelleted on the storage stability of pork. barrow (T1) and boar (T2) were alloted into six treatments: 1) control (commercial feed) 2) T1-1 and T2-1(commercial feed supplemented with 3.0％ mugwort pelleted) 3) T1-2 and T2-2 (commercial feed supplemented with 5.0％ mugwort pelleted). They were fed with the experimental diets for 60 days and slaughtered. Meat samples were in wrap package and stored at 4${\pm}$1$^{\circ}C$ for 10 days. pH, WHC and cooking loss were not siginificanly different in all treatment. But these values were tended to increase during storage for all treatment groups (p＜0.05). Thiobarbituric acid reactive substances (TBARS) and Volatile Basic Nitrogen (VBN) values were low for pork samples prepared from pigs supplemented mugwort pelleted diet and the values were increased as storage period increased for all treatment groups (p＜0.05). But L value was highest for pork samples prepared from pigs supplemented of 3.0％ mugwort pelleted diet among treatments group.

본 연구는 쑥 펠렛 사료를 거세돈과 비거세돈에게 각각 0, 3, 5%를 배합사료에 첨가급여 한 후 도축하여 등심부위를 4$\pm$1$^{\circ}C$에서 보관하면서 저장성을 분석한 결과는 다음과 같다. 돈육의 pH는 시험구에서 거세돈이 대조구에 비하여 약간 낮았지만 비거세돈은 차이가 없었으며, 가열감량과 보수력은 시험구가 대조구에 비하여 약간 높았다. 저장기간 중 돈육의 pH나 가열감량 보수력은 저장기간이 증감함에 모든 처리구에서 증가하였다.(p＜0.05). 육색의 명도(L)는 쑥 펠렛 3%첨가구가 모든 처리구 중에서 가장 높은 값을 나타내었다.
