Dry оrgаnic cоuscоus (800 grаms) is pаckaged in a rectangular semi-rigid plastic container. A sample package was taken from the production line. Contents were weighed and then dried and weighed again. Initial and dry weights were 800g and 750g, respectively. The couscous has been shown to undergo undesirable darkening reactions when stored at 25C and 40% RH. The storage warehouse is typically 25C and 60% RH (Note: Vapor pressure of water at 25C is 23.8 mmHg). (a) Sketch the moisture sorption isotherm for this product (assume that the curve is linear in the region of interest). Be sure to label axes and to Include values of mi, mc, and me (initial, critical and equilibrium moisture content) (Hint: that requires an equation for the line, so provide the equation with slope and intercept) (6 pts). (b) Specify the maximum water vapor transmission rate, WVTR, of this packaging material if the shelf life requirement is 180 days (3 pts). Recall: (c) Sketch a plot that shows how the moisture content would be expected to change with time (m(t) versus time). Show locations of mi, me and mc. (5 pts) (d) If you needed to double the shelf life, what might you recommend? (4 pts)
