The aim of this study was to evaluate the effect of treatment with ascorbic acid or calcium chloride on the quality parameters of fresh-cut kiwifruit prepared from fruit previously stored for 3 months, either treated or not treated with 1-methylcyclopropene (1-MCP) before storage. Harvested fruit were treated with 1 microL\/L 1-MCP for 20 h at room temperature ( approximately 20 degrees C) (MCP) or had no treatment (C) and were then stored at 0 degrees C. After 3 months, fruit were removed from storage, peeled, and cut longitudinally in quarters, dipped in 2% ascorbic acid (Asc), 2% calcium chloride (Ca), or just water (cont), and kept at 2 degrees C for 8 days. Measurements of firmness, soluble solids content (SSC) ( degrees Brix), color (CIE L*, a*, b*), electrolyte leakage, sugars, organic acids, total phenolics, and antioxidant activity (DPPH and ABTS) were performed at 0, 4, and 8 days. A taste panel was performed on the seventh shelf life day. It was shown that whole MCP-treated kiwifruit kept better than the control through the 3 months storage, this effect being lost through the fresh-cut shelf life period. Furthermore, the postcut dip on 2% CaCl(2) was effective on delaying softening and browning of fresh-cut kiwifruit, which were also the fruit preferred by panelists. Both ascorbic acid and CaCl(2) were effective on preserving or improving nutritional properties (phenolics, ascorbic acid, DPPH, and ABTS) mainly in the first 4 days of shelf life. The CaCl(2) had a further beneficial effect until 8 shelf life days. It is suggested that CaCl(2) is better in keeping overall quality through 8 days of shelf life at 2 degrees C in fresh-cut kiwifruit followed by Asc, and 1-MCP has negligible effect in the conditions of this experiment.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-40850","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Faculdade de Ci\u00e9ncias e Tecnologia, Universidade do Algarve, IBB, Centro de Biotecnologia Vegetal, Ed 8, Campus de Gabelas, 8005-139 Faro, Portugal. mantunes@ualg.pt","annee":"2010","mois":"5","numero":"58:10","page":"6173-81","auteurs":[{"ID":40846,"post_author":"0","post_date":"2018-12-04 02:23:02","post_date_gmt":"2018-12-04 01:23:02","post_content":"","post_title":"Antunes","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"antunes","to_ping":"","pinged":"","post_modified":"2018-12-04 02:23:02","post_modified_gmt":"2018-12-04 01:23:02","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/antunes\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":40847,"post_author":"0","post_date":"2018-12-04 02:23:02","post_date_gmt":"2018-12-04 01:23:02","post_content":"","post_title":"Dandlen","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"dandlen","to_ping":"","pinged":"","post_modified":"2018-12-04 02:23:02","post_modified_gmt":"2018-12-04 01:23:02","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/dandlen\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":40848,"post_author":"0","post_date":"2018-12-04 02:23:03","post_date_gmt":"2018-12-04 01:23:03","post_content":"","post_title":"Cavaco","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"cavaco","to_ping":"","pinged":"","post_modified":"2018-12-04 02:23:03","post_modified_gmt":"2018-12-04 01:23:03","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/cavaco\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":40849,"post_author":"0","post_date":"2018-12-04 02:23:03","post_date_gmt":"2018-12-04 01:23:03","post_content":"","post_title":"Miguel","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"miguel","to_ping":"","pinged":"","post_modified":"2018-12-04 02:23:03","post_modified_gmt":"2018-12-04 01:23:03","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/miguel\/","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":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
