숙주나물의 선도유지를 위해 포장필름(PP, OPP), 포장무게(200, 250, 300 g) 그리고 저장온도(4, 8, )를 달리하여 밀봉 포장한 후 저장기간 동안 품질변화를 살펴보았다. 포장내 기체조성은 포장무게에 관계없이 PP필름과OPP필름으로 포장한 시험구에서 및 농도가 차이를 보였으며, PP밀봉포장은 저장온도와 포장무게에 관계없이 정도의 농도를 보였으며, 농도는 온도가 높을수록 높았다. 중량 감소율의 경우 에서는 에서는 에서는 의 감소
Effects of packaging and storage temperature on the quality and shelf life of mungbean sprouts(vigna radiata (L.) Wilczek) were studied Mungbean sprouts were packaged in polypropylene films(PP) and oriented polypropylene films(OPP) with 200 g, 250 g, and 300 g and stored at and , respectively. The deterioration of quality of mungbean sprouts during storage was caused by wilting of hypocotyl, abscission of cotyledon and softening of tissue. Total weight loss never exceeded and no visible signs of shrivelling of mungbean sprouts were observed. At of OPP film per 250 g mungbean sprouts provided the optimal atmosphere composition(i.e. ). A shelf life of 6 days was achieved with these conditions. Hardness of hypocotyl, when deterioration in freshness began, was about 1,027.2 g when considerably deteriorated Hunter b value was 13 in deteriorated hypocotyl, vs. 11 for hypocotyl of fresh mungbean sprouts was accelerated by fluctuating storage temperature by the increment of storage time. It also was found that the optimum shelf life period was estimated to be 6, 2 and 2 days for 4, 8 and , respectively.
