Abstract:
Beeswax, a valuable by-product of apiculture, has often been overlooked and
underutilized in local beekeeping practices due to a lack of effective wax extraction
methods. Although various techniques exist globally, their adoption by local
beekeepers has been limited. This research aimed to evaluate the quality and quantity
of beeswax from two different sources and to compare the effectiveness of various
extraction methods in producing high-quality beeswax. Old bee comb samples of Apis
cerana and A. dorsata were randomly collected from beekeepers and honey hunters
in the Anuradhapura district were used. Four extraction methods, solar extractor,
steam extraction, manual extraction and submerged extraction method were used to
extract beeswax with three replicates in each treatment. The efficiency of the melting
and the time taken for the extraction were compared. Laboratory analysis was
performed to evaluate the physicochemical parameters i.e. color, acid value, melting
point, total volatile matter of the extracted beeswax in comparison to the
commercially available beeswax. According to the results, the effect of extraction
method, the species, or their interaction did not exhibit a significant difference in the
efficiency of melting, acid value and total volatile matter content (p>0.05). However,
the study revealed significant differences (p<0.05) in time taken to wax extraction,
melting point, and color among different beeswax sources and extraction methods.
The solar extraction took significantly longer time than manual and submerged
methods for the extraction. The beeswax obtained in this study exhibited similar
characteristics to that of beeswax available in the local market in terms of acid value,
total volatile matter content, and colorimeter values. Market-available beeswax
samples and A. cerana beeswax samples exhibited significantly similar melting
points, respectively 66.22±1.00℃ and 63.94±0.50℃, both of which were
significantly higher than that of A. dorsata beeswax samples (60.03±0.50℃).
