Horticultural practices and breeding efforts hold the potential to enhance antioxidant content in tomato fruit, but which antioxidants are most important? Lycopene content, total phenolic content, and radical scavenging capacity were examined in yellow, orange, red, and black-fruited tomato cultivars using lyophilized samples. Color was generally an accurate indicator of lycopene content, with a yellow cultivar containing less lycopene than red cultivars, and two of three red cultivars containing more than an orange cultivar. However, black cultivars as a group did not contain more lycopene than red. Tomato fruit harvested green-mature and exposed to 24 It light during ripening at 25degreesC in a growth cabinet had a higher lycopene concentration than green-mature fruit exposed for 8 h. 2,2&prime;-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid (ABTS) radical scavenging activity did not vary among different colored cultivars, and was no different in stored (2 yr) or freshly prepared lyophilized samples. Total phenolic concentration was higher in orange, red, and black fruited cultivars than in yellow. Total phenolic concentration was lower in Iyophilized powder samples of orange, red, and black cultivar fruit stored for 2 yr at -20degreesC relative to freshly prepared samples. Neither lycopene nor total phenolic concentration was well correlated to antioxidant capacity.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-52829","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"COX SE,COLORADO STATE UNIV,DEPT HORT & LANDSCAPE ARCHITECTURE; FT COLLINS CO 80523, USA. scox@npa.ars.usda.gov  \"","annee":"2003","mois":"10","numero":"83:4","page":"913-919","auteurs":[{"ID":52825,"post_author":"0","post_date":"2018-12-04 06:09:29","post_date_gmt":"2018-12-04 05:09:29","post_content":"","post_title":"Cox","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"cox-2","to_ping":"","pinged":"","post_modified":"2018-12-04 06:09:29","post_modified_gmt":"2018-12-04 05:09:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/cox-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":52826,"post_author":"0","post_date":"2018-12-04 06:09:30","post_date_gmt":"2018-12-04 05:09:30","post_content":"","post_title":"Sampson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sampson","to_ping":"","pinged":"","post_modified":"2018-12-04 06:09:30","post_modified_gmt":"2018-12-04 05:09:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sampson\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":52827,"post_author":"0","post_date":"2018-12-04 06:09:31","post_date_gmt":"2018-12-04 05:09:31","post_content":"","post_title":"Stushnoff","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stushnoff","to_ping":"","pinged":"","post_modified":"2018-12-04 06:09:31","post_modified_gmt":"2018-12-04 05:09:31","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stushnoff\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":52828,"post_author":"0","post_date":"2018-12-04 06:09:31","post_date_gmt":"2018-12-04 05:09:31","post_content":"","post_title":"CANADIAN JOURNAL OF PLANT SCIENCE","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"canadian-journal-of-plant-science","to_ping":"","pinged":"","post_modified":"2018-12-04 06:09:31","post_modified_gmt":"2018-12-04 05:09:31","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/canadian-journal-of-plant-science\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
