Problems for What-If analysis from Introduction to Food Engineering

The following provides a listing of example problems from Introduction to Food Engineering (5th Edition). The examples are presented in a manner that allows what-if analysis. Instructors and students are encouraged to use these spreadsheet type solutions to investigate the influence of various design and operating parameters for each problem. It is expected that through such analysis, a clearer understanding of the respective problems may be attained. (I will very much appreciate receiving any corrections, please email
