Abstract

The physico-chemical and functional properties of debittered moringa seeds flour were compared with soybean flour following AOAC method. The results show that ordinary defatted moringa seeds (DFMS) and debittered moringa seeds (DBMS) flours were higher in crude protein and crude fibre than defatted soybean (DFSB) flour. In vitro digestibility increased from 60.1 to 77.5% for DFMS and DBMS respectively; but these are less than that of soybean (83%). Increasing and decreasing trends of nitrogen solubility was observed for DFMS flour as pH increased giving minimum solubility at pH 4.0 and 9.0. Emulsion capacity reduced significantly for DBMS flour at all ionic concentrations; whereas for DFSB flour, the trend was similar to nitrogen solubility. Minimum gelation concentrations of the flours were 14% for DFMS flour and 10% for both DBMS and DFSB flours. Foaming capacity of DFMS and DFSB flours increased with pH, whereas for DBMS flour foaming reduced significantly and no visible change was observed as pH increased. Scanning electron micrographs showed no noticeable difference in the microstructure of DFMS and DFSB flours; however the particles of DBMS flour formed a continuous protein matrix that were devoid of air cells. Trypsin inhibitor activity was not detected in moringa seed flours but phytic acid was 0.38, 0.24 and 1.53 g/100 g for DFMS, DBMS and DFSB flours respectively. Successful removal of the bitter principle in moringa seeds holds good prospect for its utilization as an alternative source of vegetable protein; however, detailed toxicological properties still needs to be evaluated regarding the chemistry of moringa seeds protein and its interaction with other food constituents such as starch and lipids.
