Microgreens (seedlings of edible vegetables and herbs) have gained popularity as a new culinary trend over the past few years. Although small in size, microgreens can provide surprisingly intense flavors, vivid colors, and crisp textures and can be served as an edible garnish or a new salad ingredient. However, no scientific data are currently available on the nutritional content of microgreens. The present study was conducted to determine the concentrations of ascorbic acid, carotenoids, phylloquinone, and tocopherols in 25 commercially available microgreens. Results showed that different microgreens provided extremely varying amounts of vitamins and carotenoids. Total ascorbic acid contents ranged from 20.4 to147.0 mg per 100 g fresh weight (FW), while β-carotene, lutein\/zeaxanthin, and violaxanthin concentrations ranged from 0.6 to 12.1, 1.3 to 10.1, and 0.9 to 7.7 mg\/100 g FW, respectively. Phylloquinone level varied from 0.6 to 4.1 μg\/g FW; meanwhile, α-tocopherol and γ-tocopherol ranged from 4.9 to 87.4 and 3.0 to 39.4 mg\/100 g FW, respectively. Among the 25 microgreens assayed, red cabbage, cilantro, garnet amaranth, and green daikon radish had the highest concentrations of ascorbic acids, carotenoids, phylloquinone, and tocopherols, respectively. In comparison with nutritional concentrations in mature leaves (USDA National Nutrient Database), the microgreen cotyledon leaves possessed higher nutritional densities. The phytonutrient data may provide a scientific basis for evaluating nutritional values of microgreens and contribute to food composition database. These data also may be used as a reference for health agencies’ recommendations and consumers’ choices of fresh vegetables.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-37345","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Nutrition and Food Science, University of Maryland , College Park, Maryland 20742, United States.\r\n\r\n","annee":"2012","mois":"8","numero":"60:31","page":"7644-7651","auteurs":[{"ID":37343,"post_author":"0","post_date":"2018-12-04 01:15:14","post_date_gmt":"2018-12-04 00:15:14","post_content":"","post_title":"Lester","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"lester","to_ping":"","pinged":"","post_modified":"2018-12-04 01:15:14","post_modified_gmt":"2018-12-04 00:15:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/lester\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":30641,"post_author":"0","post_date":"2018-12-03 23:34:32","post_date_gmt":"2018-12-03 22:34:32","post_content":"","post_title":"Qianxin Wang","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"qianxin-wang","to_ping":"","pinged":"","post_modified":"2018-12-03 23:34:32","post_modified_gmt":"2018-12-03 22:34:32","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/qianxin-wang\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":37344,"post_author":"0","post_date":"2018-12-04 01:15:15","post_date_gmt":"2018-12-04 00:15:15","post_content":"","post_title":"Xiao","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"xiao","to_ping":"","pinged":"","post_modified":"2018-12-04 01:15:15","post_modified_gmt":"2018-12-04 00:15:15","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/xiao\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":8546,"post_author":"0","post_date":"2018-12-03 18:01:23","post_date_gmt":"2018-12-03 17:01:23","post_content":"","post_title":"Yinghua Luo","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"yinghua-luo","to_ping":"","pinged":"","post_modified":"2018-12-03 18:01:23","post_modified_gmt":"2018-12-03 17:01:23","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/yinghua-luo\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":34177,"post_author":"0","post_date":"2018-12-04 00:24:14","post_date_gmt":"2018-12-03 23:24:14","post_content":"","post_title":"J AGRIC FOOD CHEM","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"j-agric-food-chem-2","to_ping":"","pinged":"","post_modified":"2018-12-04 00:24:14","post_modified_gmt":"2018-12-03 23:24:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/j-agric-food-chem-2\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nAssessment of vitamin and carotenoid concentrations of emerging food products: edible microgreens. -
