摘要: The worldwide tendency for growing more small fruits, including raspberries, shows permanent increase because this group of fruits has a relatively higher content bioactive nutrients. To study the health benefits red raspberry 11 preselected wild-grown and 1 well-known cultivar, Heritage, were evaluated some their physicochemical properties such as fruit weight, total antioxidant capacity (measured by beta-carotene bleaching FRAP assays), phenolics, ascorbic acid, soluble solid (SSC), acidity. Fruit SSC, acid contents between 1.47 2.32 g, 10.87% 13.60%, 21 36 mg/100 respectively. Antioxidant activity phenolic varied among genotypes ERZ5 genotype had highest ascertained both methods. This also (2031 microg GAE/g FW) content. There are linear relationships capacities phenols. present demonstrates potential certain wild genotypes, notably ERZ5, improving nutritional value through germplasm enhancement programs.
