The concentrations of total phenolics significantly differed among the cultivars examined, with Lady Williams peel having significantly more phenolics (over 4000 &micro;g\/g peel fresh weight) than Crofton; (2668 &micro;g\/g peel fresh weight) and Granny Smith, which had the lowest concentration of total phenolics (1275 &micro;g\/g peel fresh weight). There were also significant differences in individual phenolics among cultivars and during storage. Quercetin glycosides were the only flavonols identified, with quercetin rhamnoglucoside being the most abundant phenolic in the peel. Chlorogenic acid was the major cinnamic acid derivative, with high concentrations, up to 412 &micro;g\/g peel fresh weight, in Crofton peel. A pre-storage diphenylamine (DPA) treatment had few significant effects on peel phenolic metabolism. Where differences did occur, fruit treated with DPA retained higher concentrations of total peel phenolics during storage than fruit not treated with DPA. Storage of all cultivars for up to 9 months in air at 0 degreesC induced few significant changes in the peel phenolic concentrations. This indicates that phenolic metabolism in apple peel is relatively stable, and the health benefits of phenolics in apple peel should be maintained during long-term-storage.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56798","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"GOLDING JB,MICHIGAN STATE UNIV,DEPT HORT; E LANSING MI 48824, USA. jbgolding@hotmail.com","annee":"2001","mois":"5","numero":"49:5","page":"2283-2289","auteurs":[{"ID":56794,"post_author":"0","post_date":"2018-12-04 07:28:59","post_date_gmt":"2018-12-04 06:28:59","post_content":"","post_title":"Golding","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"golding","to_ping":"","pinged":"","post_modified":"2018-12-04 07:28:59","post_modified_gmt":"2018-12-04 06:28:59","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/golding\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":56795,"post_author":"0","post_date":"2018-12-04 07:29:00","post_date_gmt":"2018-12-04 06:29:00","post_content":"","post_title":"Leach","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"leach","to_ping":"","pinged":"","post_modified":"2018-12-04 07:29:00","post_modified_gmt":"2018-12-04 06:29:00","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/leach\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":56796,"post_author":"0","post_date":"2018-12-04 07:29:00","post_date_gmt":"2018-12-04 06:29:00","post_content":"","post_title":"Mcglasson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"mcglasson","to_ping":"","pinged":"","post_modified":"2018-12-04 07:29:00","post_modified_gmt":"2018-12-04 06:29:00","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/mcglasson\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":56797,"post_author":"0","post_date":"2018-12-04 07:29:01","post_date_gmt":"2018-12-04 06:29:01","post_content":"","post_title":"Wyllie","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"wyllie","to_ping":"","pinged":"","post_modified":"2018-12-04 07:29:01","post_modified_gmt":"2018-12-04 06:29:01","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/wyllie\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1648,"post_author":"0","post_date":"2018-12-03 16:01:16","post_date_gmt":"2018-12-03 15:01:16","post_content":"","post_title":"Journal of agricultural and food chemistry","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-agricultural-and-food-chemistry","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:16","post_modified_gmt":"2018-12-03 15:01:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-agricultural-and-food-chemistry\/","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) -
