Présentation de l'éditeur
The principal function of this volume is to present our newer knowledge of food preparation and cookery processes from a chemical and physical basis, particularly that of colloid chemistry. In doing this, many results secured from experimental work along these lines at Iowa State College have been included. A condensed arrangement of the data on cookery, which are found in widely scattered sources, has been included also. Many of the sciences serve as a foundation or basis for food preparation. I norganic, organic, physical, and plant chemistry, as well as physics and other sciences, are necessary for an adequate understanding of many processes in food preparation. But the subject matter herein covered is perhaps more closely related to physical chemistry and the branch of physical chemistry known as colloid chemistry. In fact, so many of the ingredients used in food preparation are colloidal in nature that food preparation may be classed as one field of applied colloid chemistry. As a phase of colloid chemistry it offers a vast field for exploration, for although commercially prepared foods have been studied extensively the problems in connection with their preparation are far from completed. Work along other lines of cookery has hardly started. Some of the older work on cookery needs to be repeated and explained in the light of newer interpretations of science. Because the majority of home economics students have had no opportunity to take even an elementary course in physical or colloid chemistry, it becomes necessary to present a simple outline and explanation of colloid chemistry in its relation to food preparation. Since this is the foundation material for this treatise it seems logical to present it first. But to many persons this is the newest and perhaps the most difficult subject matter in relation to food preparation. Therefore, it is probably bet

Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
