摘要：The stability of jaboticaba skin fl our was evaluated during 12months of storage, for the purpose of extending the use of this fl ourthroughout the year, because jaboticaba production is seasonal.Ripe Plinia jaboticaba (Vell.) Berg fruits, of the Sabará genotype,were collected and the separated skins were dried at a temperatureof 45 oC. They were then ground and stored in hermetically sealedfl asks and protected from light at room temperature for 0, 3, 6, 9 and12 months. At each storage time, analyses of proximate composition,vitamin C, phenolic compounds, anthocyanins, soluble solids, wateractivity, color, pH and microbiological analysis were conducted.It was possible to observe a signifi cant increase in the followingparameters during the 12 months of storage: humidity, 34 %; wateractivity, 31.23 %; a color coordinates,12.37 % and b colorcoordinates, 24 %; pH, 7.35 %. There was a decrease in phenoliccontent of 9.91 %; anthocyanins 29 % and vitamin C 20 %. Therewas no signifi cant difference in the levels of lipids, protein, ash, fi berand soluble solids, and the presence of microorganisms was notdetected for any storage period. Therefore, it is possible to concludethat the jaboticaba skin fl our did not show signifi cant changes innutritional parameters, and showed a small reduction in antioxidantcompounds when stored for periods up to 12 months. This fl our cantherefore be considered as an alternative for the enrichment of foodproducts throughout the year
