\u00ab\u00a0Many orange-coloured fruits contain beta-cryptoxanthin in its non-esterified as well as its esterified form. Information concerning the absorption of beta-cryptoxanthin, especially with regard to the metabolism of its fatty acid esters, is rather scarce. The present study assessed the plasma concentration reached after consumption of a single dose of native beta-cryptoxanthin esters from papaya (Carica papaya L.) or non-esterified beta-cryptoxanthin in equal total amounts. In a randomized, single-blind crossover study, twelve subjects were served a portion of yoghurt containing esterified or non-esterified beta-cryptoxanthin (1.3 mg absolute) together with a balanced breakfast. Between the two intervention days, there was a 2-week depletion period. After a fasting blood sample had been taken, futher samples were taken from the subjects at 3, 6. 9, 12 and 24h. The concentration of non-esterified beta-cryptoxanthin in the whole plasma was determined by HPLC; beta-cryptoxanthin identification was confirmed by liquid chromatography-atmospheric pressure chemical ionization-MS analyses. Irrespective of the consumed diet, the plasma beta-cryptoxanthin concentrations increased significantly (P=0.05) and peaked after 6-12h. The concentration curves, as well as the areas under the curves, were not distinguishable according to two-sided F and t tests (P=0.05). Standardization of beta-cryptoxanthin concentrations to plasma triacylglycerol and cholesterol had no impact on the results. Thus, the present study indicates comparable bioavailability of both non-esterified beta-cryptoxanthin and mixtures of beta-cryptoxanthin esters. The results support the existence of an effective enzymatic cleavage system accepting various beta-cryptoxanthin esters. \u00ab\u00a0<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-53419","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"BREITHAUPT DE,UNIV HOHENHEIM,INST FOOD CHEM;GARBENSTR 28;D-70593 STUTTGART, GERMANY.breithau@uni-hohenheim.de \"","annee":"2003","mois":"10","numero":"90:4","page":"795-801","auteurs":[{"ID":53417,"post_author":"0","post_date":"2018-12-04 06:18:53","post_date_gmt":"2018-12-04 05:18:53","post_content":"","post_title":"Breithaupt","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"breithaupt","to_ping":"","pinged":"","post_modified":"2018-12-04 06:18:53","post_modified_gmt":"2018-12-04 05:18:53","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/breithaupt\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":29231,"post_author":"0","post_date":"2018-12-03 23:16:20","post_date_gmt":"2018-12-03 22:16:20","post_content":"","post_title":"Lisa A Hahn","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"lisa-a-hahn","to_ping":"","pinged":"","post_modified":"2018-12-03 23:16:20","post_modified_gmt":"2018-12-03 22:16:20","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/lisa-a-hahn\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53418,"post_author":"0","post_date":"2018-12-04 06:18:54","post_date_gmt":"2018-12-04 05:18:54","post_content":"","post_title":"Weller","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"weller","to_ping":"","pinged":"","post_modified":"2018-12-04 06:18:54","post_modified_gmt":"2018-12-04 05:18:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/weller\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":3877,"post_author":"0","post_date":"2018-12-03 17:10:14","post_date_gmt":"2018-12-03 16:10:14","post_content":"","post_title":"Maike Wolters","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"maike-wolters","to_ping":"","pinged":"","post_modified":"2018-12-03 17:10:14","post_modified_gmt":"2018-12-03 16:10:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/maike-wolters\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":41686,"post_author":"0","post_date":"2018-12-04 02:36:48","post_date_gmt":"2018-12-04 01:36:48","post_content":"","post_title":"BRITISH JOURNAL OF NUTRITION","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"british-journal-of-nutrition","to_ping":"","pinged":"","post_modified":"2018-12-04 02:36:48","post_modified_gmt":"2018-12-04 01:36:48","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/british-journal-of-nutrition\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\n
