ABSTRACT
The shelf-life of fresh moringa pods ranged between 3-5 days. This leads to heavy post-harvest losses during peak season. Moringa pods were cut into chewable size of 5.0 cm length and used in rotary dryer and filled to 65 and 80 per cent of dryer volume. Dried samples were packaged using polypropylene and multilayer packaging materials under vacuum and as normal air packaging condition and were stored at ambient (Normal temperature pressure (NTP) and at cold storage condition for three months. Moringa pods of 5.0cm length dried at 50?C, filled to 65 per cent dryer volume in a rotary dryer, packaged in multi layer film, sealed under vacuum and stored at cold storage condition recorded minimum microbial load (2x103 cfu g-1) in multilayer packaging material. Among two storage conditions adopted, cold storage recorded minimum increase in microbial loadvalue as compared to NTP storage.
Key words :
Moringa pod, Microbial load, Packaging material, Rotary dryer, Storage.
