Abstract


Multifloral honey of indigenous giant honeybee A. dorsata (wild) and Indian hivebee, A. cerana indica (apiary) were collected in and around Bangalore rural and urban districts and its physical characteristics of refractive index, optical density, viscosity and surface tension in raw, processed and stored honey were determined during February 2011 to March 2012. All the four physical characteristics tested in three grades of honey samples exhibited quantitative variations. The refractive index of A. dorsata and A.cerana raw honey was 1.47 and 1.48 respectively. Similarly optical density of processed honey of A. cerana and A.dorsata was 0.61 and 0.64 respectively. . The viscosity of A. dorsata and A.cerana stored honey was 76.82 poise and 78.94 poise respectively. Further, surface tension of A. dorsata and A.cerana stored honey was 102.31 dynes/cms and 104.13 dynes/cms respectively. The refractive index of A.dorsata raw honey was less than that of stored honey of A.dorsata. The optical density of processed honey of A.dorsata was more than of processed honey of A. cerana. Viscosity and surface tension of processed honey was less than raw and stored honey in A.dorsata and A.cerana. The analysis of variance (ANOVA) of viscosity and surface tension of raw, processed and stored honey of A.dorsata and A.cerana was significant at p
