The objective of the current investigation was to evaluate the okra before cooking (fresh) and after cooking to determine the best cooking method by using compositional analysis, colour, texture, sensory evaluation and pesticide residues reduction. The cooking methods used were steam blanching, simmering, baking and sautéing. Cooking treatments resulted in a momentous increase (p < 0.05) in crude fibre and fat content during sautéing and total carbohydrate in baking in comparison to control. The CIE lab coordinates (L* and b*) significantly decreased while a* increased in all cooking treatments except in baking. The texture analysis revealed a significant (p < 0.05) reduction in shear force N (Newton) due to contact of the heating medium in moist cooking i.e. steam blanching and simmering. Sautéing and steam blanching scored better and showed acceptance of the consumers except simmering that exhibited lower acceptability (p < 0.01). Moreover, among the analyzed pesticide residues, minimum reduction occurred in cypermethrin (8.57-37.14-%), while the chlorpyrifos was completely removed in case of baking and sautéing. Among all cooking treatments, only sautéing resulted in maximum pesticide residues reduction. The study revealed that the sautéing cooking treatment was best to preserve the vegetable nutrients compounds, maximum pesticide residues reduction and maybe among preferred cooking treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
