Abstract

Setting is an important process for the control of surimi quality in industry because it can improve the gel texture and water-holding capacity of surimi-based products. Therefore, the effect of setting on giant squid surimi-based product was analyzed via a mixture model. Konjac flour and microbial transglutaminase were used as texture enhancers. Both texture enhancers improved the texture and water retention ability (WRA) of giant squid surimi-based products, while decreasing the whiteness. Setting also improved the gel texture and WRA, while having no effect on the whiteness. Based on the sensory evaluation, the product with gel texture enhancers was better than the control and similar to commercial surimi products. Therefore, the applications of gel texture enhancers and setting are very important for the manufacture of giant squid surimi-based products.

본 연구는 자원량이 감소하고 있는 명태 등의 백색육 어류를 대체하기 위하여 백색도가 높고 잠재 자원량이 많지만 특유의 비린내가 있고 겔화가 어려운 대왕오징어에 겔 강화제를 첨가하여 품질이 향상되고 비린내를 줄인 대왕오징어 어묵의 개발과 setting의 영향을 분석하였으며, 결과를 요약하면 다음과 같다. Mixture model로 설계한 14개의 실험구에서 konjac flour와 MTGase의 양이 많을수록 gel texture는 크게 향상되었으며, 대조구에 비하여 setting을 적용한 제품의 gel texture가 더 높아 대왕오징어 어묵의 제조에 setting 공정은 반드시 필요하다고 생각된다. 대왕오징어육, 수분, konjac flour 및 MTGase의 비율이 각각 45, 40.6, 10 및 0.2%일 때 gel texture가 가장 높아 최적 배합비로 설정하였다. 본 연구에서 제조한 대왕오징어 어묵은 감자전분을 첨가한 대왕오징어 어묵에 비하여 맛과 향에서 유의적으로 높아(p<0.05) 대왕오징어 특유의 비린맛과 향을 줄일 수 있다고 생각되며, 시판 어묵과 맛과 색에서 유의적인 차이가 없어(p<0.05) 산업적으로 백색육 어류를 대체하여 활용하는 것이 가능하다고 판단된다.
