ABSTRACT

Background: Stakeholders in the corn sector are faced with a storage and / or conservation problem, which affects the quality of the fat in the grains. Objectives: to evaluate, during storage, the quality of the oil from corn kernels stored in a triple bagging system, whether or not associated with the leaves of aromatic plants. Methods: Ten batches including one control in polypropylene bag, one batch in triple bagging without biopesticides and eight batches in triple bagging with variable proportions and / or combination of Lippia multiflora and Hyptis suaveolens (between 1.01% and 5% and a combination 0 to 100% Lippia) were set up to follow the evolution of the quality indicators of the grains and oils extracted during six observation periods (0 ; 1 ; 4.5 ; 9.5 ; 14.5 and 18 months). Results: storage time and type of packaging have a significant effect on lipid quality. After 18 months of grains storage, the oil obtained from the grains of the triple bagging systems associated with at least 2.5% of biopesticides exhibits better physicochemical characteristics. These values are of the order of 0.912 (density), 52.65 mPa.s^-1 (viscosity), 1.465, 110 g I2 / 100g, 4.07 meq O2 / kg and 190 mg KOH / g (respectively for refractive, iodine, peroxide and saponification indices), 3.31% (acidity) and 1.14% (unsaponifiable content). On the other hand for the oil obtained from the grains of the triple bagging system without biopesticides, these indices have respective values of 0.941 and 47.34 mPa.s^-1, 1.462, 90.04 g I2 / 100g, 10.70 meq O2 / kg 170.43mg KOH / g, 7.92 % and 0.80 %. In addition, in the triple bagging systems associated with biopesticides, the moisture and oil levels of the grains are around 12.35 % and 5 % against 13 % and 4 % for the triple bagging lot without biopesticides at the end of storage. Conclusions: a proportion of 2.5 % of Lippia multiflora and / or Hyptis suaveolens leaves is sufficient to preserve the quality of the oil obtained from the corn stored for 18 months.
