Plot a moisture sorption isotherm for both material

Reference no: EM13215692

Moisture Sorption. The moisture sorption data for pasta and pasta sauce are listed in the following table. Both materials were dried to 7% moisture and packed
together (equal masses of each ingredient).

• Plot a moisture sorption isotherm for both materials on the same axis.
• Would there be any moisture diffusion in this system? In which direction? Using your sorption isotherm estimate the final moisture contents and water activities of each component?
Relative Humidity 0 0.112 0.226 0.438 0.518 0.577 0.660 0.753 0.843 0.903
Pasta (% moisture) 0 4.0 6.0 7.0 7.5 8.0 9.0 11.0 14.0 18.0
Sauce mix (% moisture) 0 1.0 3.0 14.0 18.0 23.0 28.0
