The total phenolics and the main flavonoids of the hydrolysed onion and garlic samples were also analysed. The antioxidant activities obtained by the two methods were compared. Both methods gave similar antioxidant activities for pure compounds and Allium extracts. However, the radical scavenging method had many benefits compared to the lipid peroxidation method, being easier, cheaper, more specific and reproducible. The radical scavenging activities also correlated positively with the total phenolics of the extracts. Onions had clearly higher radical scavenging activities than garlic, red onion being more active than yellow onion. The skin extracts of onion possessed the highest activities.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54256","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"NUUTILA AM,VTT BIOTECHOL;POB 1500;FIN-02044 ESPOO, FINLAND.anna-maria.nuutila@vtt.fi","annee":"2003","mois":"5","numero":"81:4","page":"485-493","auteurs":[{"ID":39177,"post_author":"0","post_date":"2018-12-04 01:50:38","post_date_gmt":"2018-12-04 00:50:38","post_content":"","post_title":"Puupponen-pimia","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"puupponen-pimia","to_ping":"","pinged":"","post_modified":"2018-12-04 01:50:38","post_modified_gmt":"2018-12-04 00:50:38","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/puupponen-pimia\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53279,"post_author":"0","post_date":"2018-12-04 06:16:44","post_date_gmt":"2018-12-04 05:16:44","post_content":"","post_title":"Aarni","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"aarni","to_ping":"","pinged":"","post_modified":"2018-12-04 06:16:44","post_modified_gmt":"2018-12-04 05:16:44","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/aarni\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53280,"post_author":"0","post_date":"2018-12-04 06:16:45","post_date_gmt":"2018-12-04 05:16:45","post_content":"","post_title":"Nuutila","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"nuutila","to_ping":"","pinged":"","post_modified":"2018-12-04 06:16:45","post_modified_gmt":"2018-12-04 05:16:45","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/nuutila\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53281,"post_author":"0","post_date":"2018-12-04 06:16:45","post_date_gmt":"2018-12-04 05:16:45","post_content":"","post_title":"Oksman-caldentey","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"oksman-caldentey","to_ping":"","pinged":"","post_modified":"2018-12-04 06:16:45","post_modified_gmt":"2018-12-04 05:16:45","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/oksman-caldentey\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":2399,"post_author":"0","post_date":"2018-12-03 16:55:16","post_date_gmt":"2018-12-03 15:55:16","post_content":"","post_title":"Food chemistry","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"food-chemistry","to_ping":"","pinged":"","post_modified":"2018-12-03 16:55:16","post_modified_gmt":"2018-12-03 15:55:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/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) -
