Abstract
Nutritional and anti-nutritional profiling of lentil (Lens culinaris) cultivars of Assam and West Bengal were studied from dehusked seed flour. Cultivars were collected from Regional Agricultural Research Station, Assam Agricultural University, Shillongoni (cultivars of Assam); Bidhan Chandra Krishi Viswavidyalya; Regional Research Station, Uttar Banga Krishi Viswavidyalaya, Majhian and local farmers (cultivars of West Bengal).
During this study moisture, starch, crude protein, total soluble protein, crude fat, crude fibre, ash content, minerals (P, Ca, K, Fe, Na), water-soluble vitamins, total phenolics, tannin, saponin, phytic acid content was estimated. As lentil is a pulse crop, protein is the major nutritional ingredient, fractionation of total soluble protein also done.
From this study, biochemical constituents like moisture content (12.55-13.43 g %) on fresh weight basis, starch (44.80-52.70 g %),crude protein (21.59-36.00 g %), soluble protein (19.05-35.82 g %), crude fat (0.50-1.42 g %), crude fibre (0.71-1.12 g %), ash content (2.17-2.84 g %), minerals viz. Ca (24.11-29.60 mg %), Na (25.50-26.62 mg %), Fe (6.00-7.26 mg %), P (274.57-305.72 mg %), K (749.49-768.50 mg %) and ascorbic
acid (4.08-4.40 mg %) were estimated on dry weight basis.
Further, fractionation of protein on the basis of solubility, albumin (9.05-17.86 g
%), globulin (54.12-63.84 g %), glutelin (13.77-26.62 g %), prolamin (1.91-3.99g %) were found on dry wt. basis. From UHPLC analysis some B vitamins were estimated. Anti-nutritional factors like phenol (0.12-0.20 mg/g gallic acid equivalent), tannins (5.29-
7.52 mg/g), phytic acid (8.41-9.37 mg/g), saponin (2.78-4.87 mg/g) content were calculated on dry weight basis.
The nutrient contents of the cultivars under study found to contain appreciable amount and comparable with other cultivars of lentil grown in India. On the other hand, the anti-nutritional constituents of the cultivars were found within the limits of lentil. Therefore, all those selected cultivars could be recommended for cultivation from nutritional point of view.
