Abstract

Model gel food samples of yanggaeng (Y) were prepared for the elderly with various gelling agents, including agar (AG), low acyl gellan (GL), ${\kappa}$-carrageenan (CA), locust bean gum (LB), glucomannan (GM), and xanthan gum (XA) in different combinations as follows (in 1:1 ratio): LB+CA, GM+XA, and GM+CA. The quality characteristics of the different combinations were compared. The results revealed that water loss was highest for Y-GL, whereas there was no significant difference among the other samples. Y-GL showed the highest values for lightness in color, whereas Y-AG showed the lowest. Regarding textural properties, Y-LB+CA had the highest hardness value, whereas Y-GL had the lowest; the hardness of Y was related to the cross-section of the added gel. Finally, Y-GM+XA exhibited the highest score in overall acceptability in the sensory test by elderly, indicating that the preferable texture by elderly is slightly chewy, but not adhesive.

겔화제의 종류에 따른 겔상식품의 특성을 알아보고자 대조군인 한천첨가 양갱과 다양한 겔화제를 혼합 사용한 양갱을 제조하고 그 특성을 비교하였다. 첨가되는 겔화제의 특성은 최종 제품의 수분손실량, 색, 조직감 등의 물리적 특성에 크게 영향을 미치는 것으로 나타났다. 덜 조밀하고 가장 불규칙적인 단면특성을 보이는 gellan 첨가 양갱은 수분 손실이 가장 크고, 가장 부드러우면서도 입에 들러붙는 부착성이 큰 특성을 보였다. 반면, LBG+carrageenan 겔의 혼합은 두 겔의 상호작용으로 단단한 겔을 만들기 때문에 이를 첨가한 양갱 역시 가장 단단한 경도를 보였다. 본 연구결과 고령자들은 너무 단단하지 않으면서도 응집성이 높고 탄력성이 있어 씹을 수 있는, 그러나 입에 들러붙는 부착성이 낮은 겔상 식품을 선호하는 것으로 나타났다. 두 종류의 겔을 혼합하여 적절한 농도로 겔을 제조하면 경도, 부착성, 및 응집성 등의 조직감 특성을 다양화 할 수 있으므로 적절한 겔화제의 선택, 농도조절 등으로 고령자의 저작능력에 맞는 다양한 물성을 갖는 식품제조가 가능할 것으로 생각된다.
