Depth of coverage is very high. The authors use their many years of teaching to present food engineering concepts in a logical progression that covers the standard course curriculum. Both are specialists in engineering and world-renowned. Chapters describe the application of a particular principle followed by the quantitative relationships that define the related processes, solved examples and problems t 410 0$aFood science and technology international series. 606 $aFood industry and trade 615 0$aFood industry and trade. 676 $a664 700 $aSingh$b R.
