After optimization of the production of single cell proteins using Can
dida rugosa cultures from crude palm oil used as carbonated substrate,
these yeast foods were added at the rates of 3 %, 7 % and 10 % into e
xperimental alimentary pasta of hard wheat semolina to enhance the pro
teic density of the basic product. The organoleptic evaluation was car
ried out by a metropolitan testing panel. The hedonistic appreciation
test shows that the acceptability decreases with yeast enhancement rat
e. The descriptive test results give good utterance to this appreciati
on. However, the process simplicity and the nutritional qualities of t
he yeasts obtained make this study a project applicable to most countr
ies with deficient protein diet.
