Resumo

Starch is a promising source of biopolymers and the incorporation of essential oils (EOs) into it can improve some biological properties of films.This study aimed at developing and characterizing barrier, biodegradability and optical properties of biopolymeric films made from arrowroot starch and at incorporating EOs from Piper aduncum leaves and inflorescences in order to analyze their antifungal activity against Rhizopus microsporus and Colletotrichum gloeosporioides.The casting method was used for developing arrowroot starch films and incorporating EOs into them.Resulting films exhibited satisfactory barrier properties, low water vapor permeability (WVP), transparency and good barrier property against UV-vis light, besides being 100% biodegradable.In addition, films enriched with EOs at 0.75% and 1.0% revealed promising antifungal activity.Results showed, for the first time, that arrowroot starch enriched with EOs from P. aduncum can potentially be used as an active film due to its excellent physicochemical properties and antimicrobial activity.
