초록
본 연구는 양념돈육에 분자량 약 120kDa의 키토산을 0.05에서 1.0%까지 첨가하여, 양념돈육의 보존성 및 품질에 미치는 영향에 대해 알아보기 위하여 생균수, 지질 산화도, pH, 색도와 보수력을 측정하였다. 저장기간이 경과함에 따라 양념돈육의 생균수는 증가하였으나, 키토산을 첨가한 양념돈육은 첨가하지 않은 것에 비해 생균수가 효과적으로 억제되었으며, 키토산을 0.10%. 0.50%, 1.00% 비율로 첨가했을 때는 저장 10일 동안 저장성이 상당히 유지되었다. 또한 키토산의 첨가량이 증가함에 따라 저장성도 향상되었다. 키토산을 첨가하지 않은 양념돈육은 저장기간이 경과함에 따라 TBARS의 함량이 점차 증가하였으며, 키토산을 첨가한 경우는 첨가하지 않은 것에 비해 TBARS의 함량이 대체로 낮게 나타나 지질 산화를 억제하는 것으로 나타났다. 또한 키토산의 첨가 농도가 증가할수록 지질산화 억제효과가 큰 것으로 나타났다. 양념돈육의 pH 변화를 측정한 결과 키토산을 첨가한 것이 pH가 낮았으나 저장기간 동안 거의 일정하게 유지되었다. 저장기간에 따른 양념돈육의 색의 변화를 살펴보면 키토산을 첨가한 구의 명도(L*), 적색도(a*), 황색도(b*)가 키토산을 첨가하지 않은 것에 비해 모두 높은 수치를 나타냈다. 보수력은 키토산을 첨가한 양념돈육에 있어 초기에는 낮았으나 저장 10일까지 보수력이 비교적 안정한 것으로 나타났다.
Abstract
This study was carried out to investigate the effect of chitosan on shelf-life and quality of vaccum-packaged seasoned pork. Chitosan was used 120 kDa and various concentration such as 0.05~1.0%. The total bacterial counts, pH, oxidation of lipid, surface color and water holding capacity of the sample were determined during storage periods. The total bacterial counts of seasoned pork without chitosan were increased the latter period of storage, but that of seasoned pork with chitosan was decreased such as inhibition of bacterial growth effectively. Effect on shelf-life of seasoned porks when added 0.10%, 0.50% and 1.00% of chitosan, respectively were maintained pretty well during 10 days of storage. Content of TBARS in seasoned pork without chitosan was increased than that of seasoned pork with chitosan during period of storage. And also effect of self-life and inhibition of lipid oxidation were increased with following concentration of chitosan. The variation of pH was low and stable in seasoned pork with chitosan during periods of storage. The change of color such as lightness(L*), redness(a*), yellowness(b*) in seasoned pork with chitosan was detected higher than that seasoned pork without chitosan. Water holding capacity of seasoned pork with low in the early period of storage. These colors and water holding capacity were very stable untill 10 days of storage.
