Nutritional evaluation of few grass pea (Lathyrus sativus L.) genotypes of Assam

Abstract

The grass pea genotypes exhibited significant variability in their proximate composition with moisture content ranging from 8.46 to 10.39% (on fresh weight basis), crude protein: 26.24 - 29.70%, crude fat: 1.19 - 2.34%, total carbohydrate: 50.85 - 55.34%, crude fibre: 6.57 - 8.67% and ash content from 2.68 - 3.92% on dry weight basis. Grass pea contained sodium, potassium, zinc and manganese in the range of 18.76 - 44.14 mg/100g, 710 - 1060 mg/100g, 3.03 - 5.01 mg/100g and 1.10 - 1.81 mg/100g on dry weight basis, respectively. Tannin, phenol, flavonoid, phytic acid and BOAA/ODAP content of grass pea genotypes ranged from 5.58 - 8.39 mg/g, 0.27 to 2.15 mg GAE/g, 0.02 - 0.34 mg QE/g, 5.33 - 9.57 mg/g and 0.47 - 2.23 mg/g on dry weight basis, respectively. Of the eleven grass pea genotypes used in the study, Prateek, Ratan and Mahateora showed significantly low amount of BOAA/ODAP content. Local Khesari and Boga Khesari showed average contents of nutritional characteristics. However, they were having a very high antinutritional constituents.
