Abstract
The effect of conditioning process (accelerated drying and sterilization) on safe storage of high moisture rough rice was studied. The optimum time-temperature combination of 150°C and 6 mins and a feed rate of 2.5 kg/pitch was selected for conditioning high moisture rough rice (24±1% w.b.) using a full-scale conduction heating rotary dryer (El-Sahrigi et aL, 1999). The obtained final grain moisture content and the fungal mortality level after the conditioning process were 18.23 (% w.b.) and 79.8% respectively. The conditioned grain was stored for 8 months under different storage conditions of aerated silos, non-aerated silos and sack storage method and compared with the grains dried in the open to a similar level of final moisture content. The results showed that, storage of the conditioned high moisture rough rice resulted in a grain moisture reduction up to a final level of 14% w.b. after 13 and 115 days for the aerated silos and burlap sacks storage methods respectively. However, the grain moisture content was approached about 16.8% at the end of storage period for the grain stored in non aerated silos. The drying effect of grain during storage process was greatly contributed to keep the grain without deterioration during long term storage in both aerated silos and burlap sacks. Under all storage conditions, heat-treated and sterilized grain exhibited lower broken and discolored kernels in comparison with the naturally dried grains stored under similar storage condition. The percentage of broken and discolored kernels was the lowest for grains stored in aerated silos followed by sack storage method and non-aerated silos respectively.
