This project aimed to contribute to the understanding of the interference of synthesis parameters on the properties of the nanomaterials obtained, allowing the integration of new variables into the photocatalyst project. The bench-scale testing of photocatalytic efficiency was performed using ultraviolet and visible radiation, observing the degradation of the dye and pesticide molecules through spectroscopic measurements in the UV-Vis range, electrochemical measurements, and measuring the genera

One of the main post-harvest problems is the emergence of spoilage in oranges caused especially by fungi that depreciate the quality and decrease shelf life and may also compromise food safety. Various treatment technologies such as: modified atmosphere, irradiation, anti-microbial ice and high pressure, among others, have been studied in the quest to eliminate food pathogens. Thus, understanding mechanisms of microorganism control in foods have been the topic of intense research with the use of
