The purpose of this study was to investigate the qualitative changes of the citron by identifying the type of solution and addition of the solution to prevent the browning reaction of the citron in a way that inhibits the browning of the citron. The browning inhibitor solution was investigated using...

본 논문에서 유자 표면의 색도는 무엇을 이용하여 측정하였는가? | 유자 표면의 색도는 색차계(CR-400m Konica, Minolta, Japan)를 이용하여 측정하였다. 색도는 명도(light)를 나타내는 L값, 적색도(redness)를 나타내는 a값과 황색도(yellowness)를 나타내는 b값을 측정하였으며, 총 색도는 △E 값으로 나타내었다. | |
본 논문에서 유자의 갈변도를 측정하기 위해 어떤 파장에서 흡광도를 측정하였는가? | 1 N NaOH 용액으로 적색이 될 때까지 적정하여 NaOH 용액의 소비된 용량(mL)을 구한 다음 구연산으로 환산하였다. 갈변도는 시료를 420 nm의 파장에서 흡광도를 측정하였다. | |
유자의 생산량과 재배면적은 해마다 증가하고 있으나 낮은 소비량을 갖는 이유는 무엇인가? | 유자나무는 일반 감귤에 비해 내한성 및 내건성에 강하여 겨울철 온난한 기후에서 재배가 가능하므로 국내의 제주도, 고흥, 거창, 장흥, 완도, 거제 등 주로 남해안 일대에서 재배되어 왔다(Shin 등 2005). 국내에서 유자의 생산량과 재배면적은 해마다 증가하고 있으나, 낮은 저장성과 짧은 수확기간으로 생과실로서의 이용이 어려워, 생산량에 비하여 낮은 소비량을 나타내고 있다(Kang 2006; Lee 등 2010). |
