The sample preparation procedure included both acid and alkaline hydrolysis to liberate sterols from their conjugates. The plant sterol contents of fresh vegetables ranged from 51 to 370 mg\/kg fresh weight (fw) in samples obtained from retail sale. The highest contents (&gt;300 mg\/kg) were measured in broccoli, Brussels sprouts, cauliflower and dill and the lowest (51 mg\/kg) in potato. The range of sterol contents on a dry weight (dw) basis was high, 246-4100 mg\/kg dw. Considerable variation was also observed when individual samples of some vegetables were compared. Sitosterol was the main sterol (proportion 43-86%) in all vegetables except cucumber and spinach, in which Delta(7)-sterols dominated. The total sterol contents were in the range 116-228 mg\/kg fw in all fresh fruits except avocado, which contained more sterols, 752 mg\/kg fw. In fresh berries the corresponding range was 60-279 mg\/kg fw. The wild berries lingonberry and blueberry were better plant sterol sources than the cultivated berries blackcurrant, redcurrant and strawberry. In fruits and berries the proportion of sitosterol ranged from 61-93% total sterols. On the basis of the results, the contribution of vegetables, fruits and berries to the total average daily plant sterol intake was estimated to be ca 60 mg.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54548","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"PIIRONEN V,UNIV HELSINKI,DEPT APPL CHEM & MIRCOBIOL;POB 27 LATOKARTANONKAARI 11;FIN-00014 HELSINKI, FINLAND.vieno.piironen@helsinki.fi","annee":"2003","mois":"3","numero":"83:4","page":"330-337","auteurs":[{"ID":53277,"post_author":"0","post_date":"2018-12-04 06:16:43","post_date_gmt":"2018-12-04 05:16:43","post_content":"","post_title":"Piironen","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"piironen","to_ping":"","pinged":"","post_modified":"2018-12-04 06:16:43","post_modified_gmt":"2018-12-04 05:16:43","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/piironen\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53278,"post_author":"0","post_date":"2018-12-04 06:16:44","post_date_gmt":"2018-12-04 05:16:44","post_content":"","post_title":"Lampi","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"lampi-2","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\/lampi-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"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":54547,"post_author":"0","post_date":"2018-12-04 06:46:21","post_date_gmt":"2018-12-04 05:46:21","post_content":"","post_title":"Toivo","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"toivo","to_ping":"","pinged":"","post_modified":"2018-12-04 06:46:21","post_modified_gmt":"2018-12-04 05:46:21","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/toivo\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1390,"post_author":"0","post_date":"2018-12-03 15:58:56","post_date_gmt":"2018-12-03 14:58:56","post_content":"","post_title":"Journal of the science of food and agriculture","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-the-science-of-food-and-agriculture","to_ping":"","pinged":"","post_modified":"2018-12-03 15:58:56","post_modified_gmt":"2018-12-03 14:58:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-the-science-of-food-and-agriculture\/","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) -
