Structure (micro, ultra, nano), color and mechanical properties of Vitis labrusca L. (grape berry) fruits treated by hydrogen peroxide, UV-C irradiation and ultrasound

Main structural (micro, ultra, and nano) alterations occurred in the outer tangential epidermal cell wall of Vitis labrusca L. fruits (grape berry) due to hydrogen peroxide, UV-C irradiation and ultrasound treatments were examined, and described using light microscopy, scanning electron microscopy,...
