Summary

Dill is an important aromatic herb, which is used for flavouring and seasoning of various foods and meals. As many other herbs, this product shows a high metabolism and rate of ethylene production which results in a short shelf life, lower than 10-15 days. In addition, aromatic herbs often contain pathogens such as Escherichia coli due to agricultural practices or packaging operations. In this study, a new disinfection system (based on essential oils –EOs- vapors) and active flow-pack (based on bio-polymeric film with ethylene adsorption characteristics) are proposed to maintain the quality and food safety of fresh dill in refrigerated storage at 4°C. After pretreatment with EOs vapors, a reduction of 1.5 log CFU / g was achieved for E. coli, and ethylene production in flow-packed dill was significantly lower. Thus, a shelf life of 24 days was obtained with this active packaging system.
