摘要
试验研究了生姜提取液对马铃薯淀粉膜和玉米淀粉膜的抑菌作用。试验结果表明,淀粉膜的平均水溶率为34.92%。微生物试验结果表明,生姜提取液-马铃薯淀粉膜和生姜提取液-玉米淀粉膜均对大肠杆菌和酵母菌有一定抑菌作用,抑菌效果与提取液浓度有关,即随着生姜提取液添加量的增加,淀粉膜抑菌效果越显著;对比同浓度生姜提取液的马铃薯淀粉膜、玉米淀粉膜对大肠杆菌抑制作用:马铃薯淀粉复合膜>玉米淀粉复合膜;对比同浓度两种复合膜对酵母菌抑制作用:玉米淀粉复合膜>马铃薯淀粉复合膜。
The effect of ginger extract on the potato starch film and corn starch film was studied. The starch membrane prepared under this parameter was 34.92%. The microbiological showed that the ginger extracts of potato starch and corn starch film on Escherichia coli and Saccharomycetes all have certain bacteriostatic action, and bacteriostatic effects were related to the extract concentration. As the amount of ginger extract increased, the effect of starch film was more pronounced. The starch membrane of potato starch and the starch membrane of corn starch in the same concentration was inhibited by Escherichia coli： potato starch complex film〉corn starch complex film; Inhibition of Saccharomycetes： corn starch complex film〉potato starch complex film.
