The changes in viscosity, CIE trans-reflectance color and related parameters, UV-Visible spectra and UV-spectra of oil samples in solvent system (chloroform:methanol; 2:1, v\/v) were studied. The results showed that viscosity and color of the oils changed to a much higher extent after first frying than subsequent fryings. The hue angle followed a similar trend. Changes in the UV-spectra in the solvent system indicated an increase in the formation of conjugated compounds after successive fryings. Peroxide values (PV) also increased after frying. Principal Component Analysis (PCA) plots of the data indicated that among oils examined groundnut oil and soy oil in combination with other oils were preferred for frying. Use of small amounts of unrefined oils (filtered) such as mustard oil or sesame oil which have a high content of natural antioxidants was beneficial as formation of conjugated compounds and increase in peroxide value was minimized after successive frying using blended oils.\u00a0\u00bb<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54616","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"SUSHEELAMMA NS,CENT FOOD TECHNOL RES INST,DEPT SENSORY SCI; MYSORE KARNATAKA 570013, INDIA.sensory@cscftri.ren.nic.in\"","annee":"2002","mois":"12","numero":"9:4","page":"259-276","auteurs":[{"ID":54612,"post_author":"0","post_date":"2018-12-04 06:47:24","post_date_gmt":"2018-12-04 05:47:24","post_content":"","post_title":"Asha","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"asha","to_ping":"","pinged":"","post_modified":"2018-12-04 06:47:24","post_modified_gmt":"2018-12-04 05:47:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/asha\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54613,"post_author":"0","post_date":"2018-12-04 06:47:25","post_date_gmt":"2018-12-04 05:47:25","post_content":"","post_title":"Kumar","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kumar-2","to_ping":"","pinged":"","post_modified":"2018-12-04 06:47:25","post_modified_gmt":"2018-12-04 05:47:25","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kumar-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":28248,"post_author":"0","post_date":"2018-12-03 23:04:22","post_date_gmt":"2018-12-03 22:04:22","post_content":"","post_title":"R C Travis","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"r-c-travis","to_ping":"","pinged":"","post_modified":"2018-12-03 23:04:22","post_modified_gmt":"2018-12-03 22:04:22","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/r-c-travis\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54614,"post_author":"0","post_date":"2018-12-04 06:47:25","post_date_gmt":"2018-12-04 05:47:25","post_content":"","post_title":"Susheelamma","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"susheelamma","to_ping":"","pinged":"","post_modified":"2018-12-04 06:47:25","post_modified_gmt":"2018-12-04 05:47:25","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/susheelamma\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":54615,"post_author":"0","post_date":"2018-12-04 06:47:26","post_date_gmt":"2018-12-04 05:47:26","post_content":"","post_title":"JOURNAL OF FOOD LIPIDS","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-food-lipids","to_ping":"","pinged":"","post_modified":"2018-12-04 06:47:26","post_modified_gmt":"2018-12-04 05:47:26","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-food-lipids\/","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) -
