Blackberry wine as a good source of essential mineral nutrients

Blackberry wine is a popular alcoholic beverage in Croatia and mainly produced in the continental part of the country. Traditionally, this fruit wine has been used as a popular medicine for anaemia and the iron deficiency. The aims of this study were to evaluate the mineral content in Croatian blackberry wines and investigate whether this kind of wines are a good source of essential mineral nutrients. Fifteen samples were collected during 2006 - 2007 and classified into two groups according to blackberry growing: conventional and organic samples. The mineral content of investigated blackberry wines was determined using FAAS/FAES after dry ashing procedure. The concentrations of potassium, sodium, calcium, magnesium, iron, copper, manganese and zinc were between (in mg/L) 564 - 2014, 57.84 – 212.60, 109.7 – 205.1, 69.6 – 175.5, 1.10 – 8.41, 0.085 – 0.490, 0.96 – 8.03 and 0.557 – 3.569, respectively. According to the content found, minerals were classified in two categories: the main group including K, Na, Mg, Ca, and the secondary set consisting of Fe, Mn, Cu and Zn. In regard to the obtained results, Croatian blackberry wines could be considered health safe and as a good additional source of investigated essential nutrients.
