Developing a polymeric membrane containing the essential oil of Tagetes minuta (Asteraceae)

• Development and characterization of a biodegradable film based on arrowroot starch and T. minuta essential oil.
• The essential oil of T. minuta was extracted through hydrodistillation, and the main compound was monoterpene (Z)-tagetone.
• The membranes were obtained through casting using arrowroot as a source of starch and glycerol as a plasticizer.
• The membranes obtained were translucent, flexible, homogeneous, easy to handle, and water soluble.
