Abstract
도체등급과 쑥 분말이 돼지고기 수육의 저장안정성에 미치는 영향에 대한 연구를 위하여 B등급육 또는 E등급육 (경산모돈육)에 쑥 분말을 0.3% 첨가하거나 첨가하지 않은 수육을 제조하였다. 제조된 수육은 <TEX>$4\pm1^{\circ}C$</TEX>에서 8주 동안 냉장하면서 pH, 휘발성염기질소(VBN) 함량, TBARS 값, 일반세균수 및 아질산이온 잔류량에 대하여 실험하였다. 수육의 pH는 원료육의 등급과 쑥 분말 첨가여부에 관계없이 냉장 4주까지 감소하다가 6주부터 증가하였으며, 이때에 쑥 분말을 첨가한 것이 변화의 폭이 적었다. VBN 함량은 원료육과 쑥 분말 첨가에 의한 현저한 차이가 없었다. 수육의 TBARS 값, 일반세균수 및 아질산이온 잔류량은 원료육의 등급에 따라 유의적인 차이를 나타내지 않았다. 쑥분말 첨가에 의하여 수육의 TBARS 값은 낮아지고, 일반세균수가 적게 나타났으며, 아질산이온 잔류량이 감소되었다. Addition effect of mugwort powder on storage stability of boiled carcass grade(B and E) during storage at <TEX>$4\pm1^{\circ}C$</TEX>for 8 weeks were investigated. The pH value and volatile basic nitrogen(VBN) content of boiled pork with mugwort powder were not significant difference(p>0.05) depending on the carcass grade as compared to boiled pork without mugwort powder. The thiobarbituric acid reactive substances(TBARS) values of boiled pork with mugwort powder were significantly lower than those of boiled pork without mugwort powder up to 8 weeks of the chilling process. The boiled pork with mugwort powder showed to have lower numbers of bacteria and residual nitrite than those without mugwort powder depending on the carcass grade.
