This study evaluated the nutritional and bioactive potential of germinated seeds of mangrove landrace of Canavalia cathartica of the Southwest India. Germinated seeds possess high protein, high carbohydrates, low lipid, low fibre and high calorific value. Copper, zinc and manganese meet NRC-NAS stipulated standards, while Na-K and Ca-P ratios are favourable to combat blood pressure and calcium retention, respectively. Except for the glutamic acid and tryptophan, amino acids significantly increased in cooked seeds. Most of the essential amino acids (except for tryptophan) are comparable or higher than soybean or rice or FAO-WHO standard for adults. Among the protein fractions, albumins are highest with increased albumin-globulin ratio predicts drastic decrease in antinutritional factors. Increased in vitro protein digestibility, essential amino acid score, protein digestibility corrected to amino acid score and protein efficiency ratios indicate that the cooked germinated seeds are nutritionally superior. Significant decrease in total phenolics, tannins, canavanine in cooked seeds without trypsin inhibition and lowered hemagglutinin activities further confirm suitability of cooked germinated seeds for human nutrition. The nutritional qualities of germinated seeds are comparable to traditionally consumed ripened split beans of three coastal landraces of Canavalia.
