Germinated legumes and sprouts can be potential dietary sources of bioactive compounds. In this study, selected commercially available legumes grains (chickpea, red lentil, mung bean, kidney bean and soybean), were germinated at 30 and 40 degrees C for 5 days and the antioxidant and ACE inhibitory activities were measured by the DPPH radical scavenging and in vitro ACE inhibition assay, respectively. Significant differences (p < 0.05) in total polyphenols, fiavonoids and phenolic acids contents were noted within and between grains before and after germination. Antioxidant activity varied 14-35% after germination as a result of increase in antioxidant components. Lab-on-chip analysis showed proteolysis by inherent enzymes increased during germination at 40 degrees C by 2-4 fold leading to generation of peptides of different molecular sizes. Out of the legumes studied, germinated mung and soybeans can be used in the dietary management of hypertension as their protein hydrolysates showed >82% ACE inhibition reaching an IC50 value of 0.025 mg/mL.
