Abstract

Beebread is important protein source for
honeybees in early spring. Chemical composition of beebread may vary according
to geographical origin. In this
study, proximate and fatty acids composition of five Citrus beebread samples
were determined obtained from different geographical origins. Moisture content
of citrus beebread samples varied between 11.0-16.4 %, ash 1.86-2.4 %, fat
7.0-13.4 %, and protein between 18.6-21.6 %. A total of thirty-seven fatty acids (FAs) were
identified and of these palmitic, stearic, arachidic, oleic, eicosenoic, erucic,
and linoleic acids were the most abundant in all of the samples. Beebread
sample ratios of unsaturated/saturated FAs were ranged between 1.28 and 2.23
indicating that citrus beebread is a good source of unsaturated FAs. The
pollen, proximate and fatty acid composition of beebread may vary significantly
according to its geographical origin and citrus beebread is good source
of unsaturated fatty acids.
