The purpose of this study was to investigate food preference of the elderly for the development of taurine-containing elderly-friendly foods (TEF). The subjects in this study were 278 elderly people who were over 65 years old. All data were collected by face to face interview. Statistical analysis was performed by using SPSS 20.0 for Windows. The 'low-salt diet', 'nutritional enriched diet', and 'swallow able diet' were diets that all subjects preferred. All subjects preferred a diet to be sold as three items in separate packaging, as a semi-cooked type. The food types and cooking methods that showed high preference and had a high intention to purchase were cooked rice, porridges, soups and stews, meat side dishes, fish side dishes, kimchi, and vegetable dishes and steaming Among the taurine-containing foods, whip-arm octopus, manila clam, dried anchovy, flatfish, pollack, laver, green laver, sea tangle, seaweed, cod, croaker, and cutlassfish were the preferred foods of most subjects. Elderly females preferred significantly more squid, octopus, eel, mudfish, and sea cucumber than that of elderly males (p < 0.05). Elderly males preferred and consumed significantly more taurine-supplement than did elderly females (p < 0.05). These results will be used as baseline data for development of a customized TEF for Korean elderly.
