Abstract

The comparative nutritional values of Corchorus olitorius and Melochiaorchorifolia were determined using standard analytical methods. The results were discussed using the T-test atp≤0.05.The proximate parameters determined were moisture, ash, protein, fat and carbohydrate. The respective values of ash (14.4±0.20%), crude protein (8.58±0.02%), crude fibre (2.05±0.23%), protein density (9.31±0.08) and fat density (9.31±0.08%) for C. olitorius were higher than the 12.71±0.17, 6.09±0.21, 1.65±0.04, 6.77±0.15and 25.99±1.69% respectively obtained for M. corchorifolia. On the other hand, the respective moisture (10.71±0.01%), fat (24.82±1.30%) and carbohydrate density (66.83±1.47) for M. corchorifolia were higher than the 10.23±0.06 ,12.61±0.02 and 59.51±0.09% recorded for C. olitorius. The sodium and potassium contents of the samples were determined using flame photometer model FP6410 while other minerals were determined using atomic absorption spectrophotometer (AAS) Model: Accusy 211. With exception of potassium, M. corchorifolia had higher mineral contents than C. olitorius. Functional properties were determined using standard analytical methods. The values of wettability, emulsifying capacity and gelation capacity for M. corchorifolia were higher than those of C.olitorius. However, the bulk density, foam capacity and water absorption capacity of C. olitorius were higher than those of M. corchorifolia. The amino acids profile was determined using Technicon Sequential Multi-sample Amino Acid Analyzer (TSM) and except histidine and aspartic acid, M. corchorifolia had higher values of the remaining amino acids which made the ratio of essential amino acids to non essential amino acids in M. corchorifolia to be higher than that of C. olitorius. In addition, C. olitorius had higher values of antinutritional factors.
