Abstract

미역, 파래, 톳 등 해조류의 우수한 기능성을 육제품에 활용하기 위한 기초 자료를 얻기 위하여 이들의 첨가(1, 2, 4%)가 돈육 패티의 물리 화학적 특성과 저장성 및 관능에 미치는 영향을 살펴보았다. 파래, 미역, 톳 등 모든 해조분말 첨가 패티에서 해조 첨가량이 많을수록 조회분함량이 증가하고, 패티의 CIE <TEX>$L^*$</TEX>, <TEX>$a^*$</TEX> 및 <TEX>$b^*$</TEX> 값이 감소하였다. 패티를 중심온도 <TEX>$72^{\circ}C$</TEX>에서 15분간 가열하였을 때 가열 감량을 측정한 결과 해조 분말 첨가량이 증가할수록 돈육 패티의 가열감량이 감소하는 결과를 보였으며, 특히 미역 첨가가 가장 큰 폭의 가열감량 감소를 보였다. VBN 값은 파래, 미역, 톳 등 모든 해조류 첨가군이 대조구 패티에 비해 낮았다. 해조류 분말 첨가는 패티의 다즙성을 증가시켰으며, 향미와 종합기호도에는 큰 영향을 미치지 않았다. 이상의 결과로 보아 돈육 패티 제조 시 해조류의 첨가는 패티의 회분함량을 증가시켜 돈육에 부족한 무기질 함량을 보충해주며, 패티의 가열감량 감소, 다즙성 증가 및 VBN 감소 등 긍적적 효과가 기대된다. Physicochemical properties and palatability of pork patties prepared with 3 levels (1%, 2%, and 4%) of seaweeds, sea mustard, green laver, and seaweed fusiform were studied. The addition of seaweed powders to pork patties increased crude ash content of the patties. When the patties were heated at an internal temperature of <TEX>$72^{\circ}C$</TEX> for 15 min, cooking loss was decreased as the amount of seaweed increased. Also, the addition of sea mustard showed the lowest cooking loss. Volatile basic nitrogen (VBN) of patties stored at <TEX>$4^{\circ}C$</TEX> was lower in patties containing seaweed than in the control patties. Juiciness of the cooked patties was increased in patties with seaweeds, while springiness was decreased. The addition of seaweed did not affect flavor preference and overall acceptance scores in spite of sensing seaweed flavor. In summary, the addition of seaweed in preparation of pork patties is expected to have positive effects in supplementing minerals, a reduction in cooking loss, a decrease in VBN, and an increase in juiciness.
