A Study on Structure (Micro, Ultra, Nano), Mechanical, and Color Changes of Solanum lycopersicum L. (Cherry Tomato) Fruits Induced by Hydrogen Peroxide and Ultrasound
Changes in the epidermis structure (micro, ultra, and nano), mechanical properties, and surface color of Solanum licopersicum L. fruits (cherry tomatoes) due to hydrogen peroxide (HP) and high-power ultrasound (US) treatments were examined. Both treatments induced small alterations in the epicuticul...
