Antimicrobial efficacy of Thymbra capitata (L.) Cav. essential oil loaded in self-assembled zein nanoparticles in combination with heat

•Carvacrol was identified as the major compound of Thymbra capitata oil (TCEO).•Zein, a plant protein isolated from maize, is proposed as biocompatible carrier.•Novel self-assembled zein nanocapsules loaded with TCEO (zn-TCEO) are described.•Valuable synergistic effects were obtained when combining mild heat and zn-TCEO.•The use of zn-TCEO might improve product higienization or surface disinfection.
