Van De Velde, F.; Tarola, A.M.; Güemes, D.; Pirovani, M.E. Bioactive Compounds and Antioxidant Capacity of Camarosa and Selva Strawberries (Fragaria x ananassa Duch.). Foods 2013, 2, 120-131.
Abstract
Strawberries represent an important source of bioactive compounds due to their vitamin C and phenolic compound levels, which present high antioxidant effects, beneficial for the maintenance of consumer’s health. Argentina is the second largest strawberry producer in The Common Market of the Southern Cone (MERCOSUR), covering the main export destinations of Argentinian strawberries, i.e., Canada, United States, and European Union. Information about the bioactive compound occurrence and antioxidant capacity of these fruits is scarce or not available. Health related compounds of strawberry cultivars (Camarosa and Selva) from different zones of Argentina were investigated. Vitamin C content was in the same range for both studied cultivars. However, Camarosa strawberries, which are the most cultivated, consumed, and exported berries in Argentina, presented higher total phenolic and anthocyanins content, and consequently better in vitro antioxidant capacity. Moreover, there were differences in the occurrence and concentration in the phenolic compound profiles for both cultivars. Camarosa cultivar presented higher content of anthocyanidins, and Selva showed higher total ellagic acid content. The research shows that Argentina’s strawberries are an interesting source of bioactive compounds comparable to those in other parts of the world.
Conclusions
The study of two strawberry cultivars from Argentina (Camarosa and Selva) indicated that there were differences in the bioactive compounds content and antioxidant capacity, but both were in the range of other varieties from others countries. The Camarosa cultivar presented higher total phenolic and anthocyanins content, and presented consequently a better antioxidant capacity for DPPH* and FRAP assays. However, the vitamin C content for both cultivars was in the same range. The results indicated that Camarosa strawberries, which are the most cultivated, consumed, and exported berries in Argentina, presented suitable bioactive compound levels with beneficial effects for human health. Moreover, the research points out that the strawberry varieties from Argentina are an interesting source of bioactive compounds comparable to those in other parts of the world.
