건시의 품질향상을 위하여 국내 유명산지의 건시를 시료로 하여 건시의 제조시험과 품질평가에 관한 기초자료로서 그 품질요소를 조사하였다. 건시의 수분함량은 30-36%였으며, 탄닌함량은 0-20%로 무처리구는 $CO_2$와 alcohol 처리구보다 그 함량이 높게 나타났다. 전당함량은 55-60%였고 그 구성은 glucose와 fructose로 구성되어 있었다. 열풍건조에 의한 건시의 제조는 천일건조보다 그 품질이 전반적으로 우수하였으며 특히 slice 한 제품의 품질은 전과의 경우보다 비교적 우수하였다.
This study was performed to improved the quality of dried persimmon. For this, the investigation of quality factor and processing experiments were performed. The moisture contents of dried persimmons were 30 to 36% and it was the most important component of the quality. Tannin contents were 0 to 20% and non-treated persimmon had higher tannin contents than treatment of carbon dioxide and alcohol. Total sugar contents were 55 to 60% and it was composed in glucose and fructose. Processing of dried persimmon by artificial-drying seemed to be useful when it needed to shorten the drying time or it continued rainy day during sun-drying. From the result of quality evaluation, sliced dried persimmon was better than whole dried persimmon in quality, so the sliced dried persimmon was expected that it has a little marketability.
