Abstract :In this study, the aim was to produce functional fruit leathers using wild cornelian cherry and blackthorn enriched with grape seed powder added at different rates (0%, 1% and 10%). Some physicochemical, bioactive, color and sensory properties of the produced fruit leathers were investigated. According to the results for physicochemical features of fruit leathers, % ash amount was 1.68-2.00%, % dry matter was 82.75-91.03, protein amount was 3.52-5.71%, pH was 3.04-3.43. While dry matter values were statistically significant between samples, the fruit leather samples richest in terms of ash amount were cornelian cherry and blackthorn fruit leathers containing 10% grape seed powder. The highest protein values were determined for blackthorn fruit leather containing 10% grape seed powder. The total phenolic content of Cornelian cherry fruit leather samples was 90.7-1164.0 mg GAE/100 g, while blackthorn fruit leather samples contained 52.4-1545.6 mg GAE/100 g. Fruit leather samples were determined to have significant increases in antioxidant capacity. The highest antioxidant capacity was determined in blackthorn and cornelian cherry fruit leathers containing 10% grape seed powder with values of 1969.0 mg TE/100 g and 1463.3 mg TE/100 g according to the DPPH method and 7414.1 mg TE/100 g and 4982.4 mg TE/100 g according to the CUPRAC method, respectively. The phenolic content and antioxidant capacity of wild fruit leather significantly increased with the addition of grape seed powder. While grape seed powder added to the formulation thickened the samples, the redness of the cornelian cherry fruit leathers increased, while the blueness of blackthorn fruit leathers increased. In terms of sensory features, the general approval scores between fruit leathers were affected at a statistically significant level. The 10% grape seed proportion reduced sensory approval, while the 1% rate was liked more. The highest approval was obtained for cornelian cherry fruit leather containing 1% grape seed powder.
