Cowpea (Vigna unguiculata L. Walp.) is a nutritionally important crop and has the particularity that the aerial section of the plant is entirely edible. The current research determines the nutritional composition of the alternative cowpea food sources immature pods and grains comparatively to dry grains through the evaluation of protein, minerals and different polyphenolic contents, and antioxidant capacity. Ten cowpea genotypes were analyzed during two harvest seasons. Cowpea immature pods and grains revealed high levels of total protein and K, Ca, Zn and Fe contents. In general, most of the genotypes produced cowpea of high nutritional value, with a high variation observed between them. Our results showed the potential of the introduction of new cowpea new products in the market allowing a healthy and variable diet and at the same time a better use of the crop under the scenario of climate change.<\/jats:p>","DOI":"10.3390\/plants11162079","type":"journal-article","created":{"date-parts":[[2022,8,10]],"date-time":"2022-08-10T04:20:32Z","timestamp":1660105232000},"page":"2079","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Cowpea Immature Pods and Grains Evaluation: An Opportunity for Different Food Sources"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1108-8389","authenticated-orcid":false,"given":"M\u00e1rcia","family":"Carvalho","sequence":"first","affiliation":[{"name":"Centre for Research and Technology of Agro-Environment and Biological Sciences (CITAB), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Institute for Innovation, Capacity Building and Sustainability of Agri-Food Production (Inov4Agro), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"given":"Valdemar","family":"Carnide","sequence":"additional","affiliation":[{"name":"Centre for Research and Technology of Agro-Environment and Biological Sciences (CITAB), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Institute for Innovation, Capacity Building and Sustainability of Agri-Food Production (Inov4Agro), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5614-0008","authenticated-orcid":false,"given":"Carla","family":"Sobreira","sequence":"additional","affiliation":[{"name":"Centre for Research and Technology of Agro-Environment and Biological Sciences (CITAB), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3082-4214","authenticated-orcid":false,"given":"Isaura","family":"Castro","sequence":"additional","affiliation":[{"name":"Centre for Research and Technology of Agro-Environment and Biological Sciences (CITAB), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Institute for Innovation, Capacity Building and Sustainability of Agri-Food Production (Inov4Agro), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6303-9549","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Coutinho","sequence":"additional","affiliation":[{"name":"Chemistry Centre (CQ), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5834-6141","authenticated-orcid":false,"given":"Ana","family":"Barros","sequence":"additional","affiliation":[{"name":"Centre for Research and Technology of Agro-Environment and Biological Sciences (CITAB), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Institute for Innovation, Capacity Building and Sustainability of Agri-Food Production (Inov4Agro), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"given":"Eduardo","family":"Rosa","sequence":"additional","affiliation":[{"name":"Centre for Research and Technology of Agro-Environment and Biological Sciences (CITAB), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Institute for Innovation, Capacity Building and Sustainability of Agri-Food Production (Inov4Agro), University of Tr\u00e1s-os-Montes e Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,9]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Protein-Rich Vegetal Sources and Trends in Human Nutrition: A Review","volume":"17","author":"Rawel","year":"2016","journal-title":"Curr.
