Abstract
Bael or Aegle marmelos is a spiritual, religious and medicinal plant. The pulp of the
bael fruit contains many functional and bioactive compounds such as carotenoids, phenolics,
alkaloids, coumarins, flavonoids, terpenoids and other antioxidants which may protect against
chronic diseases. Bael is also effective against cancer, cardiovascular diseases and ulcer.
Drying is the process of removal of most of the moisture present in the food. The removal of
moisture from the food materials prevents the growth and reproduction of spoilage
microorganisms, slows down the action of enzymes and minimizes many of the physical and
chemical reactions. Therefore the present research work was undertaken to studies on drying
characteristics of bael fruit pulp.
Bael fruit was procured from nearest local market and decayed fruits were discarded.
The pulp of bael fruit was extracted. The crude mass, containing seed, pulp and fibre was
added with water having equal quantity, mixed and heated for 1 min at 80°C. pH was
maintained with the help of citric acid solution. The mixture was passed through 20 mesh
sieves to separate out the seeds to obtain pulp for drying purpose. Bael fruit pulp weighing
200 g were dried in tray dryer at three drying temperatures viz. 55, 60 and 65°C and four
thickness of pulp on the tray (2, 4, 6 and 8mm). All the data were statistically analysed.
Drying took place in falling rate period and constant rate period was absent in drying
experiments. Moisture diffusivity varied in the range of 1.21 ×10-9 to 5.84×10-8.
Water activity of bael fruit pulp powder was found in the range of 0.299 to 0.460.
Ascorbic acid was found to be maximum at minimum temperature and maximum thickness
(12.3 mg/ 100g). Bael fruit powder dried at 60ºC with 2mm layer thickness, shown higher
colour value b* (39.5) and it was extremely liked by panelist than the other sample.
