Abstract

Coffee productivity and quality depend on the interaction among several factors, such as genetic characteristics of the plant cultivars, environmental conditions, management techniques and technologies from the beginning of development to the beverage production. We intend to understand such relationships using the "Internet of Things" to process data and find patterns related to the highest quality of the drink "in the cup". The candidate is expected to: evaluate, by digital image processing, the quality of the coffee harvest, determining the proportion of ripe x green beans; evaluate, through sensors and digital images, the drying conditions of the grains with humidity, temperature and intensity of sunlight; evaluate controlled fermentation conditions using sensors during the development of metabolites in specialty coffees; measure roasted and ground grain quality parameters, such as organic acid, volatile compounds, through sensors, chromatography, electronic nose and other techniques; understand how parameters related to agricultural inputs, soil, harvested and processed beans impact the sensory quality of the coffee beverage and consumer perception; collaborate with graduate students; discussion of data and writing of reports, patents and scientific articles.
