Abstract

The problem of pesticide residues in vegetables, especially leafy vegetable is the big concern to both customers and exporters. These days, plants, where people use postharvest technologies, are located in Cu Chi, Hoc Mon và Binh Chanh. Due to their simple and obsolete features, those technologies are in need of significant investment with a view to serving manufacture and accommodating customers' demand. This research aims at proposing a fresh vegetables handling process based on elements affecting the process by ultrasonic, micro bubbles and Ozone. The result of research is concentrated on studying, designing and implementing the equipment in line 200 kg/h productivity. It demonstrates an effective combination of cleaning and removing pesticide residues to the extent that is regulated by of Ministry of Health’s Food safety standards.
