Prime concerns in storage of crude and once-refined soybean oils include increases in moisture and volatile matter, color after refining or bleaching, peroxide value, free fatty acids, and refining losses. Aside from possible effects on flavor and oxidative stability, many of these quality factors also affect the commercial value of oil in trading channels. With the exception of peroxide values and refined color, the other quality factors above are written into specifications for oils sold under trading rules of the National Soybean Processors Association (NSPA) (67). 

Another most important contribution to the technical literature is the book, Official and Tentative Methods of the American Oil Chemists Society (I), which describes in great detail methods of sampling and methods of analysis which are approved by the society. This book is published in loose-leaf form, since additions and revisions are frequent. The society s committees on methods of analysis continue the never-ending job of trying to improve and simplify, the procedures. The official methods are accepted as standard by most of the trade and are also recognized by other technical organizations, such as the American Chemical Society, the National Cottonseed Products Association, the National Soybean Processors Association, and the American Association of Cereal Chemists.

Examples of the specifications for a few of the major oil types are set out in Table 5.2. The FAO/WHO Codex Alimentarius Commission have published Recommended International Standards for individual oils, and national standards bodies, for example the British Standards Institute, issue specifications.
