Oxidative stability of flax and hemp oils 总被引:1,自引:0,他引:1
Reem Abuzaytoun Fereidoon Shahidi 《Journal of the American Oil Chemists' Society》2006,83(10):855-861
Oxidative stability of flax and hemp oils, and of flax and hemp oils stripped of their minor components, was evaluated in
the dark at 60°C and under fluorescent light at 27°C. Several analytical methods were used to assess the oxidative stability
of oils. Oil extracts were also investigated for their scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and for
their total phenolic contents. The results indicate that bioactive constituents of these edible oils play a major role in
their oxidative stability. However, the FA composition of the oils and their total content of tocopherols as well as the type
of pigments present contribute to their stability. Nonstripped flax and hemp oils were more stable than their corresponding
stripped counterparts. Furthermore, nonstripped hemp oil had a higher oxidative stability than nonstripped flax oil as evidenced
by scavenging of DPPH radical and consideration of total phenolic contents. 相似文献

Sea lampreys,Mordacia mordax, were collected in spring from the Yarra River, Victoria, during their upstream spawning migration, to study the lipid composition
in their tissues and plasma and their lipid transport system. Plasma lipoproteins were isolated by preparative ultracentrifugation
and their chemical compositions were analyzed. The major classes of lipoproteins were found to be similar to those of man
and higher animals. Lipids from the muscle and liver were analyzed for fatty acids. The striking feature of the lipids in
the migrating lamprey is the presence of very high levels of cholesterol in both plasma and muscle. The possible metabolic
roles of cholesterol have been discussed. 相似文献
