The ogi powder produced was packaged in a high-density polyethylene bag (HDPE), a polypropylene woven sack (PP), and a polyvinyl chloride container (PVC), and stored in different conditions for 12 weeks with sampling done at three-week intervals for pVACanalysis. At the end of the storage period, ogi powder packaged in HDPE stored outside the storage box had the highest percentage retention (31.32%) of trans-β-carotene and that packaged in PVC container stored in the lighted compartment had the least (21.57%). Therefore, HDPE could be a good package for the retention of trans-¦-carotene (which is the most bioactive) in ogi powder when stored at a temperature of 27°C and relative humidity of 73%. http://pubs.sciepub.com/jfnr/4/2/4/jfnr-4-2-4.pdf packaging materials storage conditions ogi powder pro-vitamin A carotenoids
