中文摘要: 研究竹叶抗氧化物对三文鱼贮藏过程中品质变化的影响。将三文鱼片浸渍于 0.2 %竹叶抗氧化物溶液中, 0 ℃条件下贮藏。以感官评定、菌落总数、挥发性盐基氮(TVB-N)、pH 值、K 值及 TBA 为评价指标,研究竹叶抗氧化物 对冷藏三文鱼的保鲜效果。结果显示:在贮藏期间,三文鱼片的感官评分值呈下降趋势;菌落总数、挥发性盐基氮
(TVB-N)及 K 值均随时间的延长呈上升趋势;TBA 虽规律性不强,但大体呈上升趋势;pH 值呈先降低后上升的趋 势。浸泡 0.2 %竹叶抗氧化物的三文鱼片各项评价指标均低于对照组,感官评分值优于空白对照组,可使三文鱼片的 冷藏货架期延长 2 d~4 d。
Abstract:The effects of antioxidant of bamboo-leaf on quality changes of Salmonida slices. Salmonida slices were immersed in 0.2 % antioxidant of bamboo -leaf solution. Organoleptic evaluation,the total number of colonies, volatile basic nitrogen (TVB-N)value, pH value, K value and TBA value was periodically assessed. The resulted showed organoleptic evaluation has been showed a trend of decrease; The total number of colonies, TVB-N value,and K value of Salmonida slices stored increase with the extension of storage time; TBA value in- crease; pH value increased after cut first. 0.2 % antioxidant of bamboo-leaf could significantly decrease the to- tal number of colonies, TVB-N value , K value and TBA value and defect scores compared with the control. Antioxidant of bamboo-leaf could extend the shelf life by 2 to 4 days compared with the cotrol group .
