摘要: 本文以北高丛蓝莓中的栽培品种埃利奥特为原料,通过L16(43)正交实验,分析比较了16种提取物对副溶血性弧菌的抑菌效果及各提取物的pH值。结果表明:在30 ℃下,以65%乙醇(w/w)为溶剂,超声提取25 min为最优提取条件。采用此条件得到的提取物具有最低的pH值,在浓度为100 mg/mL和40 mg/mL时,对副溶血性弧菌的抑菌率分别达100%和81.3%。

Abstract: The bacteriostasis effect on Vibrio parahaemolyticus ATCC33847 and its pH value of 16 extracts of China blueberry (North High Bush, Alliot) were examined by L16(43) orthogonal design with the use of combinations of ethanol concentration, ultrasound time and ultrasound temperature levels. The optimal extraction conditions were 65% (w/w) ethanol and ultrasound 25 min at 30 ℃. Under this condition, the extract had the lowest pH value. When their concentrations were 100 mg/mL and 40 mg/mL, the inhibitory rate of Vibrio parahaemolyticus was 100% and 81.3%, respectively.

Key words: blueberry, extraction condition, Vibrio parahaemolyticus, ultrasound, bacteriostasis
