Abstract(s)
Because blueberries are worldwide recognized as a
good source of beneficial components, their consumption has
increased in the past decades, and so have the scientific works about
their properties. Hence, this work was undertaken to evaluate the
effect of some production and conservation factors on the properties
of blueberries from cultivar Bluecrop. The physical and chemical
analyses were done according to established methodologies and then
all data was treated using software SPSS for assessment of the
possible differences among the factors investigated and/or the
correlations between the variables at study. The results showed that
location of production influenced some of the berries properties
(caliber, sugars, antioxidant activity, color and texture) and that the
age of the bushes was correlated with moisture, sugars and acidity, as
well as lightness. On the other hand, altitude of the farm only was
correlated to sugar content. With regards to conservation, it
influenced only anthocyanins content and DPPH antioxidant activity.
Finally, the type of extract and the order of extraction had a
pronounced influence on all the phenolic properties evaluated.
