Nutritional evaluation and the effect of processing methods on antinutritional factors of sword bean (Canavalia gladiata (Jacq.) DC).

摘要

Five accessions of sword bean (Canavalia gladiata (Jacq.) DC), were collected from different agro-ecological regions of Eastern and Western ghats of Southern India and analysed for their nutritional potential. They proved to be good sources of protein (21.7-28.7%), and dietary fibre (8.2-11.2%). All the samples had good amino acid composition, nutritionally desirable unsaturated fatty acids and essential minerals. Vishakapatnam germplasm showed low levels of total free phenolics (0.55%) and tannins (0.12%). The verbascose was the major oligosaccharide in all the germplasm seed materials. The crude alpha -galactosidase enzymatic treatment effectively reduced the oligosaccharides (71.2-85.0%) compared to soaking followed by cooking (14.0-47.4%)..
