The sensory and chemical shelf-life of UHT-milk stored at room temperature and at 6 degrees C in aluminium-foil, non-foil barrier (X-board) and PE cartons were investigated. UHT milk in aluminium-foil stored in the dark has a minimum shelf-life of 6 months, while the shelf-life is 4-5 months in X-board and PE cartons. When PE cartons and X-board cartons are stored with strong light exposure at 6 degrees C, a development of light-induced off-flavour is detected after 2 and 8 weeks, respectively. The light-induced off-flavour effect is more pronounced than the effect of non-light induced oxidation of unsaturated lipids.
研究了超高温灭菌牛奶在室温以及6摄氏度条件下，分别储存在铝箔包装、非箔阻隔包装（X板）和聚乙烯纸盒中的感官和化学保质期。储存在暗处的铝箔包装超高温灭菌牛奶的最短保质期为6个月，而X板和聚乙烯纸盒包装的保质期为4至5个月。当聚乙烯纸盒和X板纸盒在6摄氏度下受到强光照射储存时，分别在2周和8周后检测到光诱导异味的产生。光诱导异味的影响比不饱和脂质非光诱导氧化的影响更明显。
