Evaluation of the quality of protein in cotyledons and radicles of selected legumes after germinating as a healthy food

Abstract

The quality of protein in cotyledons and radicles (shoot) was separately investigated in selected legumes, namely: Pisum sativum (cultivars: Terno, Xantos, Svit, Achat), Glycine max, Lupinus albus (cultivar Amiga), Pisum sativum var. arvense (cultivar Arkta), Faba vulgaris (cultivar Piestansky) after germinating for 48 hours and compared with the respective raw seeds. The highest content of amino acid in cotyledons and radicles were noted in P. sativum (Xantos) and its phenylalanine was the highest increased essential amino acid in radicles 7.4 g/16 g N with respective raw seeds 4.6 g/16 g N. The in vitro protein digestibility of cotyledons and radicles increased significantly (P < 0.05) of all legumes under study. It is ranged from 79.1% to 86.4% in cotyledons, 86.7% to 93.4%. in radicles and 54.1% to 75.0% in respective raw seeds. The quality of proteins in cotyledons and radicles of all legumes was improved significantly after germinating 48 hours.
