The physiochemical characteristics and microbiological study of spray-dried papaya powder
kept in aluminium laminated polyethylene (ALP) and polyethylene terephthalate (PET) at
accelerated storage (38 ± 2°C, 90% relative humidity (RH)) for 7 weeks were evaluated. The
final water activity (Aw) of the spray-dried papaya powder did not exceed 0.6 for both packaging
materials, which showed that the powder was shelf-stable. The overall adsorbed moisture of
spray-dried powder was significantly (p
