Abstract:
The mineral profile of fruits is allied to their nutritional value, although studies on the influence of cultivars on the profile of these micronutrients in blackberries are scarce. Therefore, the present study aimed to verify if the different blackberry cultivars (‘Tupy,’ ‘Guarani,’ ‘Xavante,’ and ‘BRS Xingu’) influence their mineral profiles. Fourteen minerals were evaluated (Al, Ba, Ca, Cu, Fe, Cr, K, Mg, Mn, Mo, Na, Ni, Sr, and Zn), and the macrominerals were: potassium (majority), calcium, magnesium, and sodium. The results showed that the type of cultivar influenced the profile of the microminerals. ‘Guarani’ presented high chromium and copper content, while ‘BRS Xingu’ presented higher manganese content than the other cultivars in both harvest periods (2016 and 2017) studied. Three of the blackberry cultivars studied can supply the lack of some microminerals, being ‘Tupy’ a source of copper and manganese, ‘Guarani’ a source of chromium and copper, and ‘BRS Xingu’ a source of manganese, chromium, and copper.
