摘要: 为了解不同贮藏温度下不同品种蓝莓果实品质特性,以天津市蓟州区主栽的8个蓝莓品种为试材,观测了10、4、0、-1 ℃条件贮藏下的果实品质变化。结果显示:Vc、花青素、可溶性糖随着温度降低下降速率逐渐变慢,总酚、类黄酮含量因品种不同变化差异较大。10 ℃贮藏中部分品种总酚含量出现先增加后降低的趋势,如‘蓝金’‘北陆’‘奥尼尔’;4 ℃贮藏中类黄酮、总酚出现先增加后降低的趋势,Vc、花青素、可溶性糖下降速率在32.94%~67.89%;0 ℃贮藏中较多品种总酚、类黄酮在贮藏到14~28 d时出现峰值,较-1 ℃贮藏21~35 d出现峰值的时间提前了7 d,如‘蓝金’‘北陆’‘莱克西’‘瑞卡’。0、-1 ℃贮藏70 d时8个品种的Vc、花青素下降速率在16.26%~65.65%。隶属函数综合分析显示,不同温度下‘布里吉塔’‘蓝金’‘北陆’的果实品质变化较小,较耐贮藏。

Abstract: In order to understand the quality among different varieties of blueberries under different storage temperatures, dynamic changes of 8 blueberries from Jizhou District of Tianjin were measured under storage of 10、4、0、-1 ℃. The results showed that with the decrease of temperature the contents of Vc, anthocyanins decreased slowly, and the content of total phenols and flavonoids varied greatly with different varieties. Total phenol of part varieties reduced after increasing, such as the ‘Bluegold’, ‘Northland’, ‘O’Neal’storage at 10 ℃; The trend of flavonoids andtotal phenols was reducing after increasing while Vc and anthocyanin decline rate was from 32.94% to 67.89% at 4 ℃; when storage for 14 to 28 days, total polyphenols and flavonoids of more varieties, appeared peak at 0 ℃ and the peak advanced 7days than at -1 ℃, such as ‘Bluegold’, ‘Northland’, ‘Legacy’ and ‘Reka’. When storage to 70 days, decline rate of Vc and anthocyanins of 8 varieties was from 20.41% to 65.65% at 0 ℃ and -1 ℃. According to the membership function, varieties with slow rate of quality decline under different temperatures were ‘Brigitta’, ‘Bluegold’ and ‘Northland’.
