As in the first edition, discussion is not confined to vegetable oils, and the hydrogenation technique is considered in detail. The why as well as the how of hydrogenation are addressed. Written for both production staff who need advice on specific problems and development personnel who seek directions, if not solutions, the book offers direct practical advice along with explanations of why changes occur as they do. The glossary of technical terms contains a more detailed explanation of some features mentioned throughout the text.
