Abstract EN

The seeds of linseed and Caraway used for human nutrition were analyzed in this study to determine some of their major chemical constituents and minerals.

The results showed that the contents of linseed and Caraway seeds were( 18.30-21.42 )& 19.80 % protein , (41.50-45.10) 16.5% & lipids,(0.9-1.1,0.3 %) phospholipids , (4.1& 6.50%) ash respectively.

Mineral contents were 685 & 668mg \100g phosphorus,225& 889 mg/100g ,calcium , 431&559 mg \100g, Magnesium , and 7.7 & 16.2 mg \100g, iron for linseed and Caraway seeds respectively .

Chromatographic analysis indicated that the major fatty acid in linseed seed oil was alfa linolenic acid(ω-3) (52.7-58.5% of total fatty acids ), and oleic acid 18.8-22.1% in linseeds.

The content of the other major fatty acids were linoleic (ω-6) 13.7-14.3 %, palmitic 5.7-6.5% and stearic 2.5-4.8 % for linseed oil and oleic 60.2%, linoleic 28.2 % linolenic 1.4, palmitic 5.98% and Myristic 1.90%, stearic 1.5 % acid for caraway seed oil .

The total unsaturated acids were 88.5- 91.6 % in linseed oil and 90.62 % in caraway oil .
