본 연구예서는 1 및 의 냉수를 이용하여 세척한 후 PP film bag과 PETE tray로 포장하여 4및 에서 9일간 저장하며 품질을 비교하였다. 에서 9일간 저장한 경우 1 및 에서 세척하고 PEIE tray로 포장한 청경채에서 감모가 거의 일어나지 않았다. 저장고에서 9일째 저장한 경우 무처리하고 PP film bag으로 포장한 청경채의 감모율 0.37 %에 비하여 로 세척하고 PETE tray로 포장한 경우 감모율은 0.19 %로 낮
Quality attributes of fresh-cut pak-choi (Brassica campestris var. chinensis) as affected by hydrocooling and packing were investigated in terms of weight loss, respiration, vitamin C content, total chlorophyll content, microbial load and sensory properties during storage at 4 and . Fresh pak-choi was trimmed and washed with cold water as well as tap water for 30 sec 3 times and then packaged in PP (polypropylene) film bag and PETE (polyethylene terephthalate) bay, and stored for 9 days at 4 and . Weight loss was decreased by washing and packing generally. Respiration rate was increased slowly over the storage at . Vitamin C content and total chlorophyll contents of pak-choi packaged within PETE bay decreased gradually during storage. Hydrocooling and packing within PETE bay treatments resulted in approximately 1-2 log CFU/g reduction of microbial load.
