Abstract
The present work was undertaken to investigate the effect of different packaging materials namely polyethylene terephthalate (PET) and aluminium laminated polyethylene (ALP) on the physicochemical properties and microbiological stability of spray-dried honey jackfruit powder over seven weeks of storage at 38 2C and 90 relative humidity. The moisture content of honey jackfruit powder packaged in PET was doubled (12.32) than of those packaged in ALP (5.31). The water activity (aw) of the powders were lower than 0.6 for both packaging materials thus considered shelf-stable. Hygroscopicity increased up to 42.44 and 39.84 for powder packaged in PET and ALP respectively. The angle of repose for powders flowability increased to 19 (ALP) and 28 (PET) which indicated that the powders flowability significantly decreased upon storage. The degree of caking for powder packaged in ALP (43.69) was much less severe than that of PET (84.51). Powder packaged in ALP showed good solubility (81.07 - 99.01) and satisfactory microbiological results ( log 2.58 CFU/g). The results recommended that ALP packaging was better suited for keeping spray-dried honey jackfruit powder.
