Nutritional potential and biochemical compounds in Cajanus albicans (wight & arn) van der maesan for food and agriculture
Main Article Content
Abstract
The chemical and nutritional composition of Cajanus albicans (Wight & Arn.) van der Maesan underexploited tribal pulses in Eastern Ghats of Andhra Pradesh were determined. The mature seed samples were analyzed for proximate composition, total (true) seed protein fractions, amino acid composition, fatty acids profile, mineral and anti-nutritional factors. The investigated seed samples contained higher amount of crude protein, crude fat, ash and nitrogen free extractives constitute of 21.35, 3.90, 3.80 and 53.90/100 seed powder, respectively of the seed weight. The calorific value of 100g dry matter of seed material was 1783.92 kj/100 Dm. The essential amino acids, isoleucine, tyrosine and phenylalanine, were presented in relatively large quantities. The fatty acid profiles revealed that the seed lipids contained higher concentrations of palmitic and linoleic acids. The seeds were rich in sodium, phosphorus, calcium, zinc, manganese and iron. Anti-nutritional factors such as total free phenols, (3.76%) tannins (7.18%), L -DOPA (0.97%), hydrogen cyanide (1.25%) and phytic acid (6.32%) were presented in variable quantities. These antinutritional factors were potentially eliminated using the conventional methods of soaking the seeds in water, boiling with water and decanting prior to consumption. From the results, these plant have a good potential as food crops in Andhra Pradesh. Their cultivation and utilization should be encouraged. This would positively contribute toward improving food security.
