ABSTRACT
I. INTRODUCTION The later chapters in this book are devoted to important sources of less common lipids and to modified materials produced mainly from commodity oils. This chapter will review the procedures available for lipid modification so that other authors need not detail the procedures and discuss their advantages and disadvantages. The procedures that have been employed may be described as technological or biological and are listed in Table I. Some of these procedures are employed to isolate or concentrate individual acids or groups of acids, which can then be incorporated into lipids by other appropriate methods, for example, the isolation of short-chain acids from lauric oils or of eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) from fish oils.
