Use of Triple Bagging Systems and Lippia Multilora Leaves for the Protein-Energy Quality Preservation of Cowpea Seeds (Vigna unguiculata L. Walp).
Abstract— Cowpea is a food legume highly appreciated in the traditional diet of the populations in Ivory Coast. It is confronted with storage and / or preservation problems which prevent his production in large quantity. This experiment carried out in Ivory Coast, made it possible to evaluate the effectiveness of the triple bagging systems combined or not with the use of Lippia multiflora leaves on maintaining the cowpea seeds protein-energy quality during preservation. Thus, a 6x6 factorial design was considered to evaluate the cowpea seeds protein-energy quality. The first factor consisted to six types of packaging namely: one control with polypropylene bag (TST), one triple bagging batch (composed of 2 internal layers in independent high density polyethylene 80 mm thick and a woven bag polypropylene) without biopesticide (H0), and four batches (H1, H2, H3 and H4) containing respectively (0.7%; 2.5; 4.3%; and 5%) biopesticide. And second factor storage time, it included six periods of observation (0; 1; 2; 4.5; 7 and 8 months). Results showed significant influence of the interaction between types of treatments and storage time upon protein-energy quality of cowpea. Indeed, the polypropylene control was destocked at 4.5 months and very significant changes were recorded in the protein-energy quality of the cowpea seeds. Also, in the triple bagging systems without biopesticide significant changes were observed to seven months of storage in the contents of moisture (10.03% to 12.55%); ash (2.73% to 2.40%); fiber (5.15% to 4.37%); lipids (1.86% to 1.40%); proteins (22.75% to 15.21%); starch (53.80% to 42.27%); total carbohydrates (62.62% to 68.44%); total sugars (15.89% to 8.15%); reducing sugars (3.12% to 2.20%) and energy value (358% to 347.20%). However, cowpea seeds stored in triple bagging systems with biopesticide retain protein energy characteristic better for eight months period. The average values of analysis tests remained around: 12.06% humidity; 2.60% ash; 4.98% fiber; 18.50% proteins; 1.73% lipids; 52.13% starch; 65.13% total carbohydrates; 14.10% total sugars; 3.00% reducing sugars and finally 350.05% energy value. The results of the multivariate analysis indicate that the 0.7% biopesticide concentration is effective and maintains the protein-energy quality of the cowpea seeds for up to 8 months.
