Abstract:
The aim of this study was to investigate some physicochemical properties of various
honey samples collected from beekeepers maintainig Apis mellifera hives in different
regions of Bangladesh during 1
st
january 2019 to 30 december 2019: The study was
conducted in the disease identification and analysis laboratory under department of
entomology In Sher-e-Bangla Agricultural University (SAU). Honey samples were
analyzed for determining pH, moisture, optical rotation, brix and fructose content. The
study revealed that all honey samples had pH, moisture, optical rotation, brix and fructose
content were ranging within 1 to 6; 15.47 to 28.13%; -1.84 to -5,deg cm2 g-1; 69.9 to
82.77% and 34.03 to 64.33 % respectively. Considering the pH, the highest pH (6) was
recorded in Mustard honey & Foreign honey (sample no.15 & 20) and lowest pH (1) was in
Fake honey (sample no. 18). In terms of moisture, the highest moisture content (29 %) was
obtained in Olive honey (sample no. 13.) and lowest moisture content (15.47 %) was
found in Mustard honey (sample no. 15.). Regarding the optical rotation,the highest
specific rotation (- 5, deg cm2 g-1) was recorded in Mustard honey. And the lowest
specific rotation (-1.84, deg cm2 g-1) was in Litchi honey (table 4). Considering of brix,
the highest amount of brix (82.77) was found in Mustard honey (sample no.15) and
lowest (69.9) was in Olive honey (sample no. 13). Regarding fructose, the highest
amount of fructose (64.33 %) was recorded in Khoilsa (Alwoan) (sample no. 6.) and the
lowest amount of fructose (34.03 %) was in Mustard honey (sample no. 15.) (Figure 3).
All samples were significantly difference of each otherat 5% level.
