— Corn is the second most cultivated cereal in Ivory Coast after rice. The grain germ represents an important source of quality fat, which could fill the deficit in fat both in populations and in industries. Unfortunately, grain production and the quality of fat are affected by storage methods that are often harmful to health. It is in this context that in the present study carried out in Ivory Coast. Surface response methodology (3-factor Central Composite Design) was conducted to monitor the effectiveness of triple bagging system and biopesticide (leaves of Lippia multiflora and Hyptis suaveolens) on the stability of some alteration parameters of the grains intended for use in oil mills. Thus, humidity, peroxide index and acidity were assessed during storage. The independent variables considered were the storage duration (1 to 18 months), the biopesticide / corn ratio (0 to 5%) and the combination of biopesticides (0 to 100% Lippia). Predictive regression equations were constructed for the estimation of each parameter studied (R2 > 0.70). An increase in grain moisture, peroxide index and acidity (P 0.05) equal to those predicted by the mathematical model. |
