The antimicrobial effects of apple‐, carrot‐, and hibiscus‐based edible films containing carvacrol and cinnamaldehyde against Escherichia coli O157:H7 on organic leafy greens in sealed plastic bags were investigated. Fresh‐cut Romaine and Iceberg lettuce, and mature and baby spinach leaves were inoculated with E. coli O157:H7 and placed into Ziploc® bags. Edible films were then added to the bags, which were stored at 4°C. The evaluation of samples taken at days 0, 3, and 7 showed that on all leafy greens, 3% carvacrol‐containing films had the greatest effect against E. coli O157:H7, reducing the bacterial population by about 5 log CFU/g on day 0. All three types of 3% carvacrol‐containing films reduced E. coli O157:H7 by about 5 log CFU/g at day 0. The 1.5% carvacrol‐containing films reduced E. coli O157:H7 by 1–4 logs CFU/g at day 7. Films with 3% cinnamaldehyde showed reduction of 0.6–3 logs CFU/g on different leafy greens.

含有香芹酚和肉桂醛的可食用薄膜可在密封塑料袋中的有机绿叶蔬菜上灭活大肠杆菌O157：H7。

研究了含有香芹酚和肉桂醛的苹果，胡萝卜和芙蓉基可食膜对大肠杆菌O157：H7的密封塑料袋中的绿叶蔬菜的抗微生物作用。将新鲜切碎的长叶莴苣和卷心莴苣以及成熟的菠菜叶和嫩菠菜叶用O157：H7大肠杆菌接种，并放入Ziploc®袋中。然后将可食用的薄膜添加到袋中，将其保存在4°C下。在第0、3和7天对样品进行的评估显示，在所有绿叶蔬菜上，含3％香芹酚的薄膜对大肠杆菌O157：H7的影响最大，当日细菌数量减少约5 log CFU / g。第0天。所有三种含3％香芹酚的薄膜均能减少大肠杆菌在第0天，O157：H7降低约5 log CFU / g。在第7天，含1.5％香芹酚的薄膜使大肠杆菌O157：H7降低1-4 log CFU / g。含有3％肉桂醛的薄膜显示降低0.6- 3在不同的绿叶蔬菜上记录CFU / g。
