본 연구는 건조 연근을 포장방법(PE 필름, PP 필름, 마대, 종이봉투)과 저장온도(-5, 0, 10, )를 달리하여 품질의 변화를 알아보기 위해서 수분함량, 경도변화, 색도를 조사하였다. 저장기간 동안 수분의 함량은 PE, PP 포장재에서 종이봉투 및 마대 처리구 보다 수분함량이 높았으며, 저장온도가 낮을수록 수분함량이 낮게 나타났다. 한편, 마대와 종이봉투 포장재는 온도에 따 시료간의 수분함량 차이에 있어서 PE와 PP의 포장재와 달리 큰
The effects of packaging materials and storage temperature on the quality of dried lotus roots (NelumbonuciferaG.) were studied during 330 days of storage. Using four commercial types of packaging, (PE [polyethylene] film bags, PP [polypropylene] film bags, gunny roll, and paper bags), and four different storage temperatures (-5, 0, 10, and ), changes in moisture content, hardness, color, and sensory qualities of dried lotus roots were investigated. The moisture contents of dried lotus roots stored in PE and PP film bags were higher than those of roots stored in gunny and paper bags. A major difference in moisture content was apparent when roots stored in gunny bags and paper bags were compared. Hue angle values were stable in roots stored in gunny and paper bags at all temperatures. Hardness decreased slightly with increased storage time in PE and PP film bags. Decay rate and marketability of roots stored in PE and PP film bags at were acceptable. The results showed that dried roots packaged with PE and PP were stable in quality, in contrast to roots stored in gunny and paper bags.
