호정화시간을 달리하여 제조한 레토르트 떡의 품질 특성

In this study, the quality characteristics of retort Tteok (Korean rice cake) prepared with various dextrinization times were investigated during storage. The moisture content of the retort Tteok made with dextrinized rice was 43.19-43.34% at 0 day and there were no differences in the samples during storage. As dextrinization time increased, the L value of the retort Tteok decreased, and the a and b values increased. Again there were no differences in the samples during storage. In the texture profiles, the hardness, gumminess and chewiness of the retort Tteok increased with increasing dextrinization time for all the samples, except the ones that were dextrinized for 32 minutes. The adhesiveness of the retort Tteok increased with decreasing dextrinization time, and springiness and cohesiveness did not differ among the samples. Also, the quality characteristics showed no differences after 15 days of storage. In the sensory evaluation, color, smell and delicate taste were significantly different between the retort Tteok made with rice dextrinized over 16 minutes and that made with no dextrinized rice. The retort Tteok with rice dextrinized for 16 minutes showed the highest score in the softness. Storage times up to 120 days made no differences in the sensory evaluation measurements. These results indicate that a dextrinization time of 16 minutes seems to give the best quality to retort Tteok made with dextrinized rice.
