It is no small irotty that consumers can be misled by true statements in advertisements. These true hes ordy work on those who do not have all the correct information. As far as unsaturated fatty acids are concerned, advertisers capitalize on the usual more is better attitude of consumers on some products, the amount of omega-9 fatty acids is also displayed in addition to omega-3 and omega-6. Does anyone in the general public have a reasonably balanced picture about omega fatty acids This sort of information is seldom taught in school.

Increased awareness by consumers of the link between an increased intake of omega-3 fatty acids and a reduction in the risk of cardiovascular disease, has led to an increased demand for products with a higher content of these... 

Linseed is one of the few vegetable sources of the omega 3 class of essential fatty acids, hence it is ideally suited for this type of product. The combination of linseed and soya produces a bread that has a low glycemic index, which is another bonus for this sort of product. This reduced glycemic index makes the product more attractive to slimmers and diabetics.

The major omega-3 fatty acid in hsh oil is eicosapentae-noic acid, which contains hve double bonds compared with only four present in the omega-6 fatty acid, arachidonic acid. When eicosapentaenoic acid is substrate for eico-sanoid production, it gives rise to prostacyclins and thromboxanes of the three series (Figure 22.9(a)) whereas when arachidonic acid is substrate, it gives rise to the two series, thromboxane A2 and prostacyclin I2. Thromboxane A3 has... 

SCCO2 fractionation of fish oil ethyl esters was employed to prepare ethyl esters of two omega-3 fatty acids. The triacylglycerol products were isolated using supercritical fluid fractionation (Nilsson et al., 1989).
