Abstrakt
European cranberry (
Vaccinium
oxycoccos
L.) and European bilberry (
Vaccinium
myrtillus
L.) are among the most popular wild
-
harvested fruits in Latvia, traditionally used in
folk
-
medicine and food. The commercial cultivation of American cranberry (
Vaccinium
macrocarpon
Ait.) and highbush blueber
ry (
Vaccinium corymbosum
L.) was successfully started
during last 20 years.
With a
berry production increase due to considerable hectarage of plantings
and growing consumer interest in health
-
improving foods cultivated blueberries and cranberries
have foun
d a place in a daily intake as an
excellent
source of phenolic and nutritive compounds,
vitamins and minerals. As the chemical composition of
Vaccinium spp
. has an
important
implication on human health, detailed information on the nutritional content of berries are of
special importance. The aim of this study was to compare the contents of twelve biologically
essential elements (N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, Mo, B) in b
erries of four
Vaccinium
species: cultivated and wild blueberries (
Vaccinium corymbosum
and
Vaccinium
myrtillus
) and
cranberries (
Vaccinium macrocarpon
and
Vaccinium oxycoccus
). Together 136 (leaf and berry)
samples were collected from 7 main cranberry and
blueberry producing sites and 17 native
woodland areas and bogs in Latvia. A comparison of wild and cultivated species showed similar
concentrations for the macroelements K, Ca and S in cranberry and N, P in blueberry fruits. While
statistically significa
nt differences were found for N, P and Mg in case of cranberries and Ca, K,
Mg and S for blueberries. The research revealed statistically significant differences of most
micronutrients in cultivated and wild berries. Plant leaf and fruit analysis revealed
the
organ
-
specific
distribution of mineral elements in all species
studied.
In most of the
cases,
leaf analysis
supported concentration differences in fruits.
