Abstract
AbstractConsumption of fruits and vegetables is shown to be beneficial for protecting health and preventing some chronic diseases such as cancer, cardiovascular disease, and stroke. The positive health effects have been mainly due to the contributions of their natural antioxidant capacity. Chokecherry (Prunus virginiana), a unique fruit, is a member of the Rose family and native to North America. Here we demonstrate that chokecherry fruit with strong antioxidant capacity is available in Manitoba, and that its potent antioxidant potential can be developed for health benefits in value-added applications.These findings are useful for developing novel value-added antioxidant products from chokecherry because of its phytochemical profile associated with health protection and prevention of disease. The results provide evidence essential for breeding novel cultivars of fruit plants with strong natural antioxidants.
Highlights
Consumption of fruits and vegetables is shown to be beneficial for protecting health and preventing some chronic diseases such as cancer, cardiovascular disease, and stroke[1,2]
Almost all of the total antioxidant capacity is attributed to the phytochemicals present in fruits, such as phenolic acids, anthocyanins, proanthocyanidins, vitamin C et al Significant differences in phenolic acid composition and levels were found between chokecherry and other Manitoba fruits (Table 1)
Caffeic acid levels decreased in the order: saskatoon berry > wild blueberry > red strawberry > raspberry > seabuckthorn
Summary
Consumption of fruits and vegetables is shown to be beneficial for protecting health and preventing some chronic diseases such as cancer, cardiovascular disease, and stroke[1,2]. The positive health effects have been mainly due to the contributions of their natural antioxidant capacity[3]. We demonstrate that chokecherry fruit with strong antioxidant capacity is available in Manitoba, and that its potent antioxidant potential can be developed for health benefits in value-added applications.
