Title: Antioxidant activity and storage regime of grape seeds flakes – a waste product in wine elaboration
Keywords: grape; grape seeds flakes; grape seeds; antioxidants; winery

Abstract: The current scientific research is focused on the grape seeds – a waste product retrieved after alcoholic fermentation of wine, in the form of grape seeds flakes. Recently, the grape residue has been considerated as a functional food product, a source of bioactive compounds (BAC) including antioxidants. The present study presents data about the antioxidant activity of grape seeds flakes of different grape varieties of Bulgarian origin, analysed via four analytical methods differ in mechanism and reaction conditions, namely DPPH, ABTS, FRAP and CUPRAC. The obtained results were expressed as mM TE/g extract (842.50 ± 34.75; 959.63 ± 65.05; 94.73 ± 10.42 and 200.24 ± 48.60, respectively) and mM TE/g flakes (as follows 141.40 ± 5.83; 161.06 ± 10.92; 94.89 ± 10.44 and 200.56 ± 48.68). The grape seeds flakes were stored at room temperature – 25°С and relative air humidity of 75%. The storage regime was optimized to one month by means of packaging the product in a co-extruded barrier film wi
