A five volume set, much expanded over previous editions, to cover the latest processing technology as well as the latest developments in oilseeds. This is the definitive text that covers fats and oils, composition, processing and equipment, edible products, industrial products and derivatives (e.g. soap.) The only drawbacks are that there is no common index to all volumes and that there is a great deal of valuable information which is not findable through the index (i.e. one must actually READ the sections to unearth valuable facts and bits of information.)
