초록

본 연구에서는 고품질의 곤드레 제품을 얻기 위한 방법으로 데치기 처리에 따른 곤드레의 품질 특성을 비교 분석함으로써 건제품 개발을 위한 전처리 조건 및 가공기술에 대한 기초자료를 제시하고자 수행하였다. 데치기 조건과 식염 첨가량에 따른 곤드레에 대한 색도의 변화는 데치기를 실시하는 동안 곤드레의 색도는 온도에 영향을 나타내었고, 데치기 온도가 증가할수록 a값과 b값은 감소하는 경향을 나타내었으나, L값은 증가하는 경향을 나타내었다. 또한, 첨가되는 식염에 따른 표면 색도는 b값은 높아짐을 나타내었으며, a값은 낮아지는 수치를 나타내었지만 유의적인 차이를 나타내지 않았다. L값은 식염 첨가에 따라 변화를 나타내지 않았다. 데치기 온도가 높아질수록, 시간이 길어질수록 곤드레의 경도가 감소하므로 데치기 처리에 의해 곤드레 조직이 부드럽게 되는 것을 확인할 수 있었다. 또한, 식염의 첨가에 의해서 경도가 증가하는 경향을 보였으나, 유의수준(p<0.05)에서 차이를 나타내지 않았다. 온도가 증가함에 따라 총 chlorophyll 함량은 증가하는 반면, chlorophyll a 및 b의 비율(Ca/Cb)은 감소하는 경향을 나타내었다. 총 폴리페놀함량은 신선한 곤드레에 비하여 데치기 온도가 증가함에 따라 감소하는 경향을 나타내었지만, 첨가되는 염의 양에 따라 약간의 증가를 나타내었으나 유의적인 차이는 없는 것으로 나타났으며, 전반적인 관능검사는 데치기 처리 온도가 높아짐에 따라 기호특성이 증가하는 경향을 나타내었다. 따라서 우수한 곤드레의 생산을 위해서는 관능적인 기호특성이 가장 우수한 것으로 나타난 데치기 공정($100^{\circ}C$, 3% 염첨가)에서 실시하는 것이 좋을 것으로 판단된다.

This study was carried out to investigate the change of the quality of wild edible plants, Cirsium setidens Nakai, blanched at various conditions. Samples were blanched under blanching conditions of $90^{\circ}C/25min$, $95^{\circ}C/15min$, and $100^{\circ}C/5min$, with salt concentrations of 0%, 1%, 2%, 3%, 4% and 5%. The color, texture (hardness), chlorophyll and total polyphenols were analyzed. The contents of polyphenol and hardness in Cirsium setidens Nakai were found to be decreased in relation to blanching time. With respect to sensory evaluation, the 3% treatment had a higher overall acceptability than other treatments. The optimal blanching condition was found to be $100^{\circ}C/5min$ and 3% salt.
