Abstract

This study investigated the optimal mix ratio of frozen-dried loquat fruit powder and the optimun conditions for making Seolgidduk by analyzing chemical properties, rating moisture contents, color, mechanical quality characteristics and sensory characteristics Seolgidduk was made with 0, 2, 4, 6 and 8% frozen-dried loquat fruit powder, which contains functional components. Chemical analysis showed that loquat fruit powder contained of 12.87% water, 2.23% crude protein, 0.55% crude fat, 3.57% crude ash and 3.89% crude fiber. Water content of Seolgidduk containing loquat fruit ranged from 36.58~39.18%. With more loquat fruit powder L value decreased, while the 'a' value and 'b' values increased. According to scanning electronic microscopy, Seolgidduk containing frozen-dried loquat fruit powder showed weak coherence. Hardness decreased with more frozen-dried loquat fruit powder. In the sensory test, Seolgidduk with 4% loquat fruit powder was the most preferred with less sourness, proper softness, moisture and chewiness. Based on the results of this experiment, Seolgidduk with 4% loquat fruit powder showed less hardness than the control group. These results show that quality and preference increased when 4% loquat fruit powder was added to Seolgidduk. Therefore, Seolgidduk with 4% of loquat fruit powder is expected to increase quality and preference of Seolgidduk.
