Chemical composition and nutritive value of some wild-gathered tropical plant seeds

As part of the search for alternative sources of food to alleviate hunger, this study reports the approximate total contents of soluble sugars, starch, and gross energy of nine lesser-known wild-gathered plant seeds. High crude protein levels occurred in Lonchocarpus sericeus (28.03%), Albizia zygia...

Description
Summary:As part of the search for alternative sources of food to alleviate hunger, this study reports the approximate total contents of soluble sugars, starch, and gross energy of nine lesser-known wild-gathered plant seeds. High crude protein levels occurred in Lonchocarpus sericeus (28.03%), Albizia zygia (32.90%), and Gliricidia septum (34.15%). High levels of fat occurred in Entandrophragma angolense (59.30%), L. sericeus (34.15%), and Millettia thonningii (30.66%). Low levels of crude protein but high levels of total carbohydrate were found in Diospyros mespiliformis (77.21% carbohydrate), Daneillia ogea (74.32% carbohydrate), and Afzelia belle (53.96% carbohydrate). Starch contents were high in A. zygia (40.46%), D. ogea (69.62%), and A. belle (51.43%). The seeds with high fat content invariably showed high gross energy levels: E. angolense (30.9 kJ/g), L. sericeus (24.37 kJ/g), and M. thonningii (25.12 kJ/g). The results are compared to those for soya bean and other common staples. It is concluded that these less familiar wild seed plants should not be ignored, but further investigation into possible toxic and antinutrient factors, amino acid patterns, digestibility, and fatty acid composition is still required before recommendations are made.
