Abstract

We investigated the quality properties of pork jerky prepared with various humectants (Konjac, egg albumin, isolated soy protein). Jerky was prepared as follows; control with no humectants, treatments with 0.05, 0.1, and 0.2% humectants, respectively. Humectant treatments had higher drying yields of pork jerky than the control (p<0.05), Konjac treatment produced the the highest drying yields among the humectants tested. CIE a-and b-value were lowest in isolated soy protein treatments. b-value in 0.2% egg albumin treatments were higher than other treatments (p<0.05). Jerky water content increased as humectant content increased. Water activity (Aw) in 0.2% Konjac treatments was higher than controls and 0.05% Konjac (p<0.05). In textual profile evaluations, control samples had greater hardness, cohesiveness, gumminess, and chewiness values than other treatments, but very low springiness (p<0.05). Control had significantly (p<0.05) lower scores than the other treatments in sensorial texture, juiciness and overall acceptability. Based on our findings, we conclude that 0.05% Konjac was the most effective humectant among those we tested in this study.

본 연구는 돼지 후지육을 이용하여 Konjac, egg albumin 및 isolated soy protein를 다양한 수준으로 첨가하여 제조한 육포의 품질특성을 측정하여 조직감을 개선한 육포를 제조하기 위해 실시하였다. 보습제를 첨가한 처리구가 대조구에 비해 높은 건조수율을 나타내었으며(p<0.05), 그중 Konjac 처리구가 다른 보습제 처리구보다 높은 건조수율을 보였다. 명도(lightness)를 나타내는 L값은 처리구 간에 유의적인 차이가 없었으며, 적색도(redness)를 나타내는 a값은 isolated soy protein 처리구가 다른 처리구에 비해 유의적으로 낮았다. 또한 황색도(yellowness)를 나타내는 b값은 egg albumin 0.2% 처리구가 가장 높게 나타났으며, isolated soy protein처리구가 다른 처리구에 비해 유의적으로 낮게 나타났다. 보습제를 첨가한 처리구가 대조구에 비해 유의적으로 높은 수분함량을 나타내었으며, Konjac 0.2% 처리구가 대조구와 Konjac 0.05% 처리구에 비해 유의적으로 높은 수분활성도를 나타내었다. 각 육포의 물성 측정 결과, 대조구가 다른 처리구들에 비해 가장 높은 hardness, cohesiveness, gumminess, chewiness값과 가장 낮은 springiness값을 나타내었으며. 관능평가에서는 연도, 다즙성 및 전체적인 기호도에서 대조구가 보습제 처리구보다 유의적으로 낮은 평가를 받았다. 따라서, 보습제로 Konjac을 첨가하여 제조한 육포가 다른 처리구에 비하여 품질특성상 우수하였으며, 첨가수준 간에 차이가 없어 최종적으로 Konjac 0.05%를 사용하여 제조한 육포가 가장 효과적인 것으로 사료된다.
