초록

저지방 소시지에 키토산(30-50 kDa)을 0.3과 0.6%를 첨가하여 pH및 일반성분을 분석한 결과 키토산의 첨가에 의해 pH는 감소하였으나 키토산의 첨가량의 증가에 의한 유의적 차이는 나타나지 않았다. 수분과 지방, 단백질, 가열감량에서는 키토산의 첨가에 의한 영향이 나타나지 않았으며 보수력에서는 유화형 소시지와 비교했을 때 키토산을 첨가한 소시지가 유리수분의 양이 많아짐으로써 낮은 보수력을 나타냈다. 조직적 검사에서는 부서짐성을 제외한 모든 항목에서 키토산의 첨가에 의해 조직감이 상승하였고, 견고성의 경우 키토산의 첨가에 의해 값이 크게 상승하였으나 키토산의 함량의 증가에 의한 유의적 차이는 보이지 않았다. 점도는 저지방 소시지의 경우 키토산의 첨가에 의해 변화가 없었으나, 유화형 대조구와는 유의차를 보였다. 관능검사는 모든 항목에서 유화형 소시지의 선호도가 가장 높았으며 키토산의 첨가에 의한 기호도는 약간 감소하는 것으로 나타났다. 결과적으로 저지방 소시지에 키토산을 첨가함으로써 소시지의 pH와 보수력를 저하시켰고, 조직감의 수치를 상승시켰으나 관능적으로 0.3%이하로 첨가 시 저지방 소시지의 품질에 큰 영향을 주지 않는 것으로 평가된다.

Physicochemical and textural properties, and sensory evaluation of low-fat sausages (LFSs) manufactured with 0.3 and 0.6% chitosan were investigated and compared with those of regular-fat sausages (RFSs). Although the batter pH was not changed with the addition of chitosan (p>0.05), product pH was reduced (p>0.05) with the addition of chitosan up to 0.6%. Proximate composition and cooking loss (%) were not affected by the addition of chitosan. Expressible moisture 1r91ues (EM, %) of LESs were lower (p<0.05) than those of RFSs, but not affected by the addition of chitosan. The addition of chitosan in the sausage formulation became harder, springier and more cohesive (p<0.05), whereas, no differences were observed (p>0.05) in these values of sausages containing between 0.3 and 0.6%. Batter viscosity was not affected by the addition of chitosan, but LESs with or without chitosan had lower viscosity than RFSs due to high moisture (%). Sensory evaluation results showed that LFSs containing 0.3% chitosan had most parameters similar to those of low-fat control. These results indicated that chitosan at the level of 0.3% can be used for the manufacture of LFSs without quality defect.
