Abstract

This study provides a comparative analysis of linseed varieties, specifically examining two high-yielding varieties (DLV6 and DLV7) alongside a local variety (BL) focusing on their nutritional attributes. DLV6 and DLV7 demonstrated superior physico-chemical properties and bioactive compounds, such as dietary fiber (34.59 % -40.61 %), secoisolariciresinol diglucoside (19.24–24.92 mg/g) and diverse phenolic compounds. Fatty acid compositional analyses revealed that DLV6 exhibited exceptional lipid health indices such as total unsaturated fatty acids (87.46 %), MUFA/PUFA ratio (0.38), PUFA/SFA (5.02), oleic desaturation ratio (0.43), atherogenicity index (0.14), thrombogenicity index (0.07), oxidability (12.38), hypocholesterolemic/hypercholesterolemic index (12.09) and peroxidisability index (113.62). To highlight differences in the nutritional composition of linseed varieties, multivariate statistical analyses including principal component analysis (PCA), hierarchical clustering and correlation analysis were carried out. PCA accounted for 100 % of the total variability, with two components explaining 64.23 % and 35.77 % variance, respectively. High yielding varieties were positioned at higher positive end and were distinct from the local variety. These analyses confirm that high yielding varieties outperformed the local variety in all nutritional metrics, underscoring their potential as nutrient-dense choices for balanced diets.
