This study was performed to investigate the perception and preferences regarding commercial universal design foods (UDF) made with different ingredients. A one-to-one interview was used for data collection and the survey was conducted on 41 elderly people (over age 65; males: 11, females: 30) attending senior welfare centers in Seoul. Twelve UDF samples were collected, which were widely sold in Japan. Majority of respondents prepared meals (53.7%) and ate alone (43.9%), respectively. The preferred cooking level of elderly food was "ready to eat (RTE)" (43.9%) or "ready to heat (RTH)" (43.9%) rather than fresh cut product. In most, the elderly had no problem with chewing-action (90.2%). Generally, food ingredients such as grain, meat, seafood and fruits showed higher preference than vegetable and nuts. Among 12 UDF samples, pumpkin gratin (4.17) and peach flavored jelly (4.27) showed higher preferences among tested samples on a 5-point facial hedonic scale. There were no significant differences in overall preferences of all samples by difficulty in terms of chewing and swallowing of respondents. Demi-glace sauce hamburger and pot sukiyaki were more preferred as age increased (p<0.05).

본 연구에서는 육류와 어류의 효소 처리 및 재구성에 의해 물성 조절 고령친화식품을 이용하여 이화학적 및 감각특성과 기호도 분석을 통해 다각적으로 고령친화식품의 개발 방향성을 연구하였다. 효소 처리 고령친화식품의 이화학적 성분 분석 결과 가용성 고형분, 염도, pH에서 효소 처리와 대조군 사이의 유의적인 차이가 나타나지 않았다. UDF 기준에 따른 경도 측정 결과 대조군인 CBS, CSS 모두 일반식에 해당하는 경도를 나타내었고, ESS는 UDF 2단계, ESS는 UDF 1단계에 해당하는 경도로 측정되었다. 재구성 고령친화식품인 TES, TMR의 경우 모두 UDF 2단계 기준에 해당하는 경도를 나타내었다. 소비자 조사에서 외관과 경도, 씹힘성에서 효소 처리 시료가 대조군 보다 낮은 강도를 나타내며 효소 처리를 통한 경도 저하 효과를 확인할 수 있었다. 재구성 시료 모두 낮은 경도와 씹힘성을 나타내고, 7점대의 높은 목넘김성으로 평가되어 연하 및 저작장애 고령자를 대상으로 한 고령친화식품으로서의 조건에 부합하는 결과를 나타냈다. 향후 고령인구의 증가와 함께 고령자의 먹는 즐거움과 더불어 기능적, 영양적으로 충족되는 고령친화식품이 개발되어 앞으로 다가올 초고령화 시대에 대비해야 할 것이다.

Korea has entered into an aged-society in 2018. If this trend continues to increase, it is expected that a super-aging society will take place by 2026. Therefore, Korea is placed in the situation of becoming the world's fastest aging nation as it becomes a super-aging society from an aged-society in twenty-six years. In order to provide an effective supply of nutrition for the socially weak, Japan developed a variety of foods with food texture improvements. Germany improved accessibility for meal service development. Senior-friendly food is a softened food or a highly concentrated drink, which is considered a texture-modified food, for the elderly with eating disorders to digest food more easily by making food particles smaller. Varying food processing techniques such as freeze-thawing enzyme impregnation, high-pressure processing, super-heated steam processing, 3D food print, and others used to produce texture-modified foods.
