Alternative methodology of special coffee roasting in the electric popcorn maker

The aim was to develop and evaluate an alternative method for roasting coffee, using a domestic electric popcorn machine, estimating an ideal roasting time to obtain a drink of high quality. The experiment was conducted under laboratory conditions, with 10 treatments, with roasting times ranging from 3 to 8 minutes. Grain mass reduction and roasting color classification, according to the ABG Agtron scale, were evaluated. Roasting was carried out in a domestic electric popcorn maker, from Mondial brand, model PP-04, with a power of 1200W. Time intervals of five to six minutes showed better coffee characteristics, medium roasting point, ideal for specialty coffees. The use of the popcorn machine as a coffee roaster showed a satisfactory result, since in a short period of time, it provided a uniform roast, which attributes superior quality, compared to conventional coffee found on the market.
