Which of the following cannot be determined from a moisture

  Which of the following cannot be determined from a moisture sorption isotherm?

a.         Rate and extent of drying.

            b.         Optimum frozen storage temperature.

            c.         Glass transition temperature.

            d.         Moisture barrier requirements for packaging

Solution

the answer is A

because moisture sorption isotherm shows the relationship between water content and humidity content of a material. the material which is most commonly used for study is food. it helps in predicting the rate and extent up to which the food material can be dehydrated for its taste and preserving attribute.
