The negative outcome of germination and fermentation on the physical and chemical properties of protein isolate
Keywords:
Fermentation, germination, physicochemical properties, Mucuna, protein isolate.Abstract
The proximate composition and functional properties of fermentated and germinated Mucuna
cochinchinensis protein isolates were determined. Mucuna bean protein extracted at pH 8 and pH 10
had protein contents ranging from 89.6 to 90.1% for the fermented Mucuna bean flour while the
germinated bean ranged from 88.1 to 89.8%. There were significant (P<0.05) differences in the results of
some of the functional properties of the Mucuna bean isolates at different fermenting and germinating
periods. However, oil and water absorption, emulsion capacity, bulk density, foaming capacity and
gelation capacity compared favourably with soy and winged bean isolates. Thus Mucuna bean isolate
with its high protein content and good functionality has a good potential for application in food
systems.
