In this context, the objective of the present work was to evaluate the extraction of phenolic compounds from the peel of Jabuticaba (Myrciaria jaboticaba (Vell.) O. Berg), Sabará. Initially, the parameters of power amplitude (40 and 80%) and granulometry (9, 16 and 32 mesh) of the dehydrated peel were evaluated in anthocyanin extraction. Then, the experiment planning methodology was used to maximize anthocyanin extraction, evaluating the influence of time (11.55 to 138 min) and temperature (16.67 to 53.3 ºC), keeping the amplitude of the potency (40%), solid-ethanol ratio (1:25, m/v), quantity of lyophilized peels (moisture of ~3.5%) crushed (10 g) and volume of acidified ethanol pH 1 (250 mL). A second-order model allowed to maximize the ultrasound-assisted extraction, obtaining a maximum content of 700.94 mg/100g of total anthocyanins, under conditions of 48 ºC and 30 min, power amplitude of 40%, solid-ethanol (1:25, 10 g of peel and 250 mL of ethanol).pt-BREngenharia de AlimentosJabuticabaCompostos fenólicosExtração assistida por ultrassomExtração assistida por ultrassom de antocianinas da casca de jabuticaba (Myrciaria cauliflora)Trabalho de Conclusão de Curso
