Calculate the water activity of the brand at this elevated temperature and comment on it’s integrity. Should the delivery still push through? Or should the products be recalled and disposed
You are a food specialist in a company that specializes in
refrigerated delicacies, and one of your brands requires being
maintained at a temperature of 5°C. You determine average
water activity (aw) at this temperature to be 0.2.
One day, you are informed that the cooling systems on
one of the delivery trucks carrying your company’s products
malfunctioned while en route to its destination and it would not
be fixed until the next delivery. The driver has informed you that
the temperature in the delivery bay of the truck is averaging
55°C. You estimate a heat of sorption (Q) of 19 kJ/mol.
