The Influence Of Isomerised Plant Oils With High Content Of Conjugated Dienes Of Linoleic Acids c9,t11 And t10,c12 On The Fat Reduction In The Carcass And Meat of Lamb

An influence of isomerised poppy seed oil on lamb body fat and fat content in meat, and also fatty acids content was determined in the research. As a result of poppy seed oil isomerisation, the synthesis of conjugated dienes of linoleic acid of trans-10, cis-12 and cis-9, trans-11 configuration in amounts 34.3% and 32.2%, respectively, occurred. The enrichment of feed dose of fattening lambs with this additive caused body fat reduction at a level from 13 to 37%, and a lowering of fat content in muscular tissue from 13 to 27 percentage points. An addition of isomerised poppy seed oil also profitably modified the content of fatty acids in adipose tissues causing an increase of biologically active beneficial components such as : c9,t11 and t10,c12 isomers of linoleic acid, vaccenic acid, and a decrease of saturated fatty acids content.
