Chemical Composition of Different Varieties of Linseed
The present study was conducted to investigate chemical composition of six varieties of linseed (Chandni, LS-29, LS-49, LS-70, LS-75 and LS-76). Proximate composition, mineral profile and cyanogenic glycosides (linamarin) were determined. Average proximate composition values for linseed i.e. crude p...

| description | The present study was conducted to investigate chemical composition of six varieties of linseed (Chandni, LS-29, LS-49, LS-70, LS-75 and LS-76). Proximate composition, mineral profile and cyanogenic glycosides (linamarin) were determined. Average proximate composition values for linseed i.e. crude protein, ether extract, crude fiber, ash and nitrogen free extract were 24.18, 37.77, 4.78, 3.50 and 25.86%, respectively. Higher values of crude protein, ether extract, crude fiber and nitrogen free extract were observed in varieties LS-49, LS-70, LS-29 and Chandni, respectively. Average mineral contents in linseed i.e. Ca, Mg, K, Na, Cl, P, Cu, Fe, Mn and Zn were 0.39, 0.09, 1.41, 0.05, 0.08, 0.89, 4.67, 50.56, 8.29 and 13.55 ppm, respectively. Among micro minerals, varieties LS-29 and LS-70 were higher in Cu contents; LS-75 was higher in Fe content, while LS-49 was higher in Mn and Zn contents. Among macro minerals, level of Ca was higher in LS-70, levels of Mg, K and Na were higher in Chandni, while P was higher in LS-49. Average amount of linamarin in linseed was 31.05mg/100 gm DM. The variety LS-75 had the highest (35.22 mg/100 gm) linamarin content, while variety LS-70 had least (26.22 mg/100 gm) amount of linamarin. In conclusion, there is significant difference in chemical composition among linseed varieties. The varieties LS-49 showed higher crude protein content, LS-70 showed greater oil content, while LS-75 had higher content of linamarin. |
