    abstract = {The study aimed to establish the storage
stability of flour blends from fermented and unfermented
sorghum, soybean and Orange Fleshed Sweet Potato
(OFSP) at 25, 30 and 40. The flours blends [F2: Sorghum:
Soybeans: OFSP (56:17:27) %; F3: Sorghum: Soybeans:
OFSP (59:31:10) %; UF2: Sorghum: Soybeans: OFSP
(56:17:27) %; UF3: Sorghum: Soybeans: OFSP
(59:31:10) %; were generated using mixture design of
Response Surface Methodology (RSM). The Equilibrium
Moisture Content (EMC) of the blends and Control (CT)
sample were determined by static gravimetric method.
The EMC were calculated and moisture sorption
Isotherms were plotted for the dried samples. The
monolayer Moisture (M<sub>0/sub>) content of the samples was
evaluated at each temperature by applying BET
(Brunaeur-Emmett-Teller) and GAB (Guggenheim-
Anderson-De Boer) equations to the isotherm data and the
experimental data were fitted to four commonly used
models using linear regression analytical procedure. EMC
of flour blends decreased with an increase in temperature
at constant water Activity (A<sub>w</sub>) and increased with an
increase in Relative Humidity (RH) at constant
temperature. The sorption isotherm curves of the blends
and CT were sigmodal in shape. GAB, BET and Oswin
models gave a better fit for sample F2, Oswin and
Henderson gave a better fit for sample UF2, Oswin gave
a better fit for sample F3. Oswinand GAB gave a better fit
for sample UF3 while Henderson and GAB gave a better
fit for sample CT at temperatures 25, 30 and 40&deg;C,
respectively.}
