Abstract

A surimi like material was made from fresh pig hearts and used to manufacture emulsion-type sausages for the improvement of quality characteristics. The heart muscles were diced and frozen at -60$^{\circ}C$ until processed. Then, the frozen diced heart muscles were thawed, chopped, filtered, and washed to extract myofibrillar proteins. The residue was centrifuged to take a surimi-like material. Emulsion-type sausages were made different levels of surimi-like material(5∼15%) and compared to the control. Cooking loss(CL, %) and water-holding capacity (WHC, %) were measured on raw meat batter, whereas shear force, hardness, color and panel test were measured after cooking. The addition of the surimi-like material up to 15% level in the sausage formulation reduced CL and increased WHC, as compared to the control. Shear force and hardness values of the control had the highest value, however sausages containing 15% surimi-like material had the lowest value(p<0.05). Increased surimi-like material became darker in color. Although no differences in panel scores of flavor and off-flavor were observed, panellists prefer to select sausages having 15% surimi-like material(p<0.05). These results indicated that a surimi-like material, which was a myofibrillar protein extracted from pig hearts, could be used to manufacture emulsion-type sausage up to 15% to improve cooking yield and textural characteristics without color and flavor defects.

본 연구는 유화형 소시지 제조시 이용되는 원료육에 대해 돼지 심장근으로부터 획득한 근원섬유 단백질 추출물인 수리미 유사물의 대체첨가가 제품의 품질특성에 미치는 영향을 구명하고자 수행하였다. 그 결과, 원료육에 대해 15% 수리미 유사물을 대체한 처리구가 대조구에 비해 가열감량은 유의적(p<0.05)으로 낮게 나타났고, 보수력은 유의적(p<0.05)으로 높게 나타났다. 전단가 및 경도에 있어서도 수리미유사물의 대체처리구가 대조구에 비해 유의적(p<0.05)으로 낮게 나타났다. 육색에 있어 명도(L)는 수리미유사물을 대체한 처리구가 대조구에 비해 유의적(p<0.05)으로 낮게 나타났으며, a, b값은 유의적인 차이가 나타나지 않았다(p>0.05). 한편, 관능검사 결과 대조구와 처리구간에 향미와 불쾌취에 있어 유의적인 차이가 나타나지 않았지만, 전체적인 기호도에 있어 15% 수리미유사물 대체처리구가 유의적(p<0.05)으로 높은 점수를 얻었다. 이상의 결과를 종합해 볼 때, 유화형 소시지제조시 돼지 심장근에서 획득한 근원섬유 단백질 추출물을 원료육 대비 15%까지 대체하더라도 가열감량을 낮춰 제품 수율을 높일 뿐만 아니라 보수력을 높이고 조직감을 부드럽게 하여 기호성을 증진시키는 효과를 얻을 수 있을 것으로 사료된다.
