Different packaging and storage conditions of water activity in dried moringa under rotary dryer

I. P. Sudagar, P. Aruna

Abstract :

 Drumstick (Moringa oleifera Lam) is belongs to the moringa family Moringaceae. The shelf life of fresh moringa pods ranged between 3–5 days. This leads to heavy post harvest losses during peak season. Fresh moringa pods (Annual Moringa type cv PKM–1) handpicked from Horticultural College and Research Institute, TNAU, Periyakulam, Tamil Nadu were used for the study. Pretreatment was given by dipping in boiling water with magnesium oxide (0.1%) for 15 seconds. Moringa pods were cut into chewable size of 5.0cm length and used in rotary dryer. Moringa pods 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 5.0 cm 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 water activity value in multilayer packaging material and among two storage conditions adopted, cold storage recorded minimum increase in water activity value as compared to NTP storage.
