These show up in the derivation of equations where the same physical principles are generally used as the starting point in the derivation. The description of equipment is included only when it is essential in establishing how parameters for their efficient operation are selected. Quantification of the relationships between operating variables equipment size and product quality is the primary objective of food process engineering as presented in this book. The coverage of subjects of contemporary interest enables students to connect the relevance of the subject matter to their career development. News media articles trade publications and announcements of symposia or short courses may be used as a guide in the selection of subjects of contemporary interest. A review chapter on mathematics is included. This was viewed as a useful feature in the first edition. It is recommended that this chapter not be taught as a review of mathematics but rather as assigned reading prior to the first use of a mathematical principle in the solution of a problem in later sections of the textbook. BASIC programming is also included. The use of computers is becoming more common in schools and in the workplace and in the coming decade most college-bound high school students should be familiar with writing and using computer programs.
