캠벨' 포도주스의 이화학적 및 관능적 품질특성에 저온 안정화 처리기간이 미치는 영향을 조사하기 위하여, 포도 과실로 압착 주스를 제조하여 에서 30일간 보관하면서 주스의 각종 품질특성 변화를 조사하였다. 주스의 당/산비와 pH는 증가하였으나 적정산도와 가용성 고형분 함량은 경시적으로 감소함을 보였다. 주스의 명도( 값)와 황색도( 값)는 증가하는 경향을 보였으며 적색도( 값)는 감소하는 경향을 각각 나타내었다. 주스의 총페놀, 안토시아닌, 플라보

The demand of packaged baby leaves has been increased for its convenient use as fresh-cut produce. This investigation was aimed to explore the effects of different sanitizers on the quality parameters of 'Tah Tasai' Chinese cabbage (Brassica campestris var. narinosa) baby leaves. Thirteen days old baby leaves were harvested and washed in tap water (TW), 100 ppm chlorine solution (Cl), 2 ppm ozonated water (), 15 ppm chlorine dioxide solution () and washing with 0.2% citric acid solution followed by 50% ethanol spray (CA+Et). The samples were then packaged in 50 polyethylene bags and stored at for 10 days. Off-odor of packaged baby leaves was not detected during storage. There was no significant difference in color parameters among the treatments. Samples treated with showed substantially higher electrolyte leakage throughout the storage. This treatment also rendered a higher accumulation of in the packages. Samples treated with Cl and CA+Et maintained good overall visual quality with higher scores compared to that of and . Although Cl treatment showed lower number of total aerobic count at the beginning of storage, citric acid in combination with ethanol treatment was more effective until the end of storage. The combined treatment also showed comparatively lower coliform plate count. This result indicates that citric acid wash followed by ethanol spray could be an alternative to chlorine for environment friendly sanitization of baby leaves.
