Nutritional and anti-nutritional properties of certain underexploited legume seeds

Abstract

Wild underexploited edible legume seeds, Cassia obtusifoliu, Entada scandens and two germplasms of Phuseolus lunatus, were investigated for their proximate composition, minerals, seed protein fractions, amino acid profiles, fatty acid composition and certain anti-nutritional substances. The seeds of P. lunatus (both germplasms) had a higher content of crude protein than cultivated lima beans. C . obtusifolia and E. scandens were rich in crude lipid and crude fibre. All four wild legume germplasm seed samples appeared to be good sources of minerals: iron, zinc and manganese. While the globulins constituted the major seed proteins in C. obtusifolia and E. scandens, albumins formed the major seed protein fraction in both germplasms of P. lunatus. Seed lipids in all the investigated samples contained a large proportion of unsaturated fatty acids with linoleic acid as the predominant fatty acid. With the exception of E. scandens, the seed materials contained low levels of free phenols, tannins and L-DOPA. Haemagglutinating activity was also assayed.

Nutritional prospective of Sesbania species: an underutilized wild legume from Northern Western Ghats, Maharashtra, India

“…In Sesbania bispinosa 59.08% carbohydrate was noted, While in S. grandiflora is was 34.91%. Reported content found to be in consonance with earlier reports on other wild legumes Canavalia ensiformis (46.1%), Canavalia gladiata (45.1%), and Canavalia maritima (44.9%) (Bressani et al, 1987) and Alysicarpus rugosus (51.1%) (Siddhuraju et al, 1992) and Entada scandens (45.99%) (Vijayakumari et al, 1993). Lipid content was found to less in both the species i.e.…”

Effect of Various Processing Methods on the in Vitro Starch Digestibility and Resistant Starch Content of Indian Pulses

“…The nutritional significance of pulses has recently promoted the search for new, underexploited legume species as potential sources of energy and nutrients. In this respect, most work in the literature deals with the study of the protein and antinutritional factors of such little-known legumes (Carnovale et al, 1991;Siddhuraju et al, 1995aSiddhuraju et al, ,b, 1996Sudha et al, 1995), as well as on the effects of processing on protein digestibility and antinutrient activity (Adewusi and Falade, 1996;Barimalaa and Anoghalu, 1997;Veena et al, 1995;Vijayakumari et al, 1993Vijayakumari et al, , 1995Vijayakumari et al, , 1996. However, little attention has been paid to the influence of processing on the digestibility of starch, the main carbohydrate fraction of these little-known legumes.…”

Nutritional and Antinutritional Properties of the Underexploited Wild Legume <i>Rhynchosia bracteata</i> Benth

“…The food energy value of the seed was 366.86 K. cal due to the protein, lipid and NFEs rich ture. The seed protein fractionations content of Rhynchosia breacteata is given in constitute the major bulk of the seed proteins as in many other legumes, and percentage distribution of both proteins are more or less equal to that of Vigna sesquipedalis (Rajaram and Janardhanan, 1990), Vigna trilobata (Sidduraju et al, 1992) Phaseolus lunatus (Vijayakumari, et al, 1993) and Abrus precatorius (Mohan and Janardhanan 1995). The data on fatty acid composition of the seed lipids (Table III) indicated that palmitic, linoleic, and stearic acid are the predominant fatty acids.…”
