In this lecture, we will show how equipment and instrumentation, constructed in our laboratories, has been applied for the extraction/fractionation of lipid and botanical moieties, as well as for the analysis of pesticides, lipids, nutrients, and mycotoxins. In addition, the lecture will emphasize how results obtained in one area of research (i.e., analytical/process) can be used in another to considerable advantage. Specific examples that will be discussed are: (1) the development of enzymatic conversion methods under supercritical conditions, for the production of industrially useful esters and the subsequent use of the method in NLEA-mandated nutrient analysis, (2) analytical scale defatting of meats for pesticide residue analysis and its scaled-up application for the removal of fat and cholesterol from ground beef, (3) development of a process to isolate and fractionate phospholipid moieties from seeds and its implications in analytical chemistry, (4) the role of analytical scale supercritical fluid chromatography in optimizing both analytical- and process-scale SFE, and (5) the use of a parallel multi-sample extractor for the simultaneous extraction of samples and real time optimization of extraction conditions. A particular emphasis will also be placed on the role of analytical scale equipment in screening processing sorbents for use in supercritical industrial-based processes. |
