Résumé:
The cowpea (Vigna unguiculata L. Walp), known as string bean, is a crop of great socioeconomic importance for the Northeast Region, with vast genetic variability available. Therefore, the objective was to evaluate the postharvest quality of four green cowpea genotypes. The genotypes were collected in the experimental area of the Center for Agro-Food Science and Technology of the Federal University of Campina Grande, in Pombal-PB, transported to the Laboratory of Chemistry, Biochemistry and Food Analysis and analyzed for physical, physical-chemical and compound parameters bioactive. The experimental design used was completely randomized, consisting of four cowpea genotypes (costela de vaca, pingo de ouro, paulistinha and BRS marataoã) evaluated in 4 replications and submitted to the Tukey test at a 5% probability level. The genotypes costela de vaca e marataoã stood out in terms of soluble solids, titratable acidity, chlorophyll, carotenoids, flavonoids, anthocyanins and ascorbic acid. While the pingo de ouro genotype had the lowest concentrations. The cow rib genotype showed good physical and bioactive attributes, contributing to the maintenance of post-harvest quality.
