ABSTRACT
This research work is on the effect of packaging materials on the functional properties of white garri. in the research work ,three packaging materials were used, namely rice bag, baco bag and plastic bowl. The functional properties that were tested for in this research work were bulk density wettability, gelation capacity, pH, gelatinization temperature, oil absorption capacity, and water absorption capacity.
The result of the experiment gave the following bulk density, the value varies from [0.53/ml] for plastic bowl,[0.56/ml] rice bag and[0.61/ml] baco bag, for the wettability it was found out that the garri will dissolve at a time of 11.48sec.for baco bag,15.48sec,plastic bag,and19.67sec for rice bag.
The gelation capacity for the garri stored in all the three packaging materials was gotten to be 0.1 the ph test for the garri stored with the three packaging materials gave 2.80,3.2,7.8 for rice bag, baco bag, and plastic bowl respectively. Also for water absorption capacity test, the garri packaged with rice bag gave [0.5], baco bag[0.2] and plastic bowl[1.5g].
Finally for the oil absorption capacity test, the garri packaged with rice bag gave[0.457],baco bag[0.730],and plastic bowl[1.370].
Generally the study has shown that rice bag and baco bag are not moisture proof or air tight, while the plastic bowl will make the garri vulnerable to fungi growth and deterioration cause of lack of aeration in the plastic bowl.
