| dc.description.abstract | The effects of packages, storage conditions and the length of storage on the physicochemical and chemical properties of ogi powder produced fromyellow maize grain were investigated. Ogi was produced using the traditional method, dried at 55°C to a powder in a cabinet drier, milled, cooled andpacked in high-density polyethylene bag (HDPE), a polypropylene woven sack (PP), and a polyvinyl chloride container (PVC). The samples werestored under different conditions for 12 weeks and sampled at three-week intervals for analysis. Significant differences were observed for all thephysicochemical and chemical properties of the ogi powder investigated except for the water absorption capacity and the ash content. At the end ofthe storage period, PVC-packed ogi powder stored in the dark compartment of the storage box had the highest degree of yellowness (2632.33) andHDPE bag-packed ogi powder stored in the lighted compartment had the least one(2424.33). Ogi powder packed in PVC stored in the darkcompartment had the highest final viscosity (193 RVU) and that packed in PP woven sack stored in the dark compartment had the lowest one(185RVU). Ogi powder packed in PP woven sack stored in the lighted compartment had the highest setback (89 RVU) while that packed in PP woven sackand stored in the dark compartment had the lowest one (82 RVU). The overall mean of the sugar content at the end of the 12 weeks of storage was1.14%; PP woven sack (2%) and PVC (0.59%) packed ogi powder stored in the lighted compartment of the storage box had the highest and lowestvalue, respectively. The overall mean of the starch content at the end of the 12 weeks storage period was 53.81%; ogi powder packed in PP woven sackand stored in the lighted compartment had the highest (66.1%) and ogi powder packed in PP woven sack stored in the dark compartment had the least(42.86%) value. After 12-weeks of storage, moisture content increased from 5.5% before storage to 10.23% in ogi powder packed in PP woven sacks andstored in the dark compartment. Therefore, HDPE bag could be used to store ogi powder at a temperature of 26.10-27.90°C and relative humidity rangeof 63-75% and ogi powder packed in PVC can be stored at a temperature and relative humidity range of 27.20-30°C and 58-66%, respectively, for goodproduct quality. | |
