Bleaching and Purifying Fats and Oils: Theory and Practice

Since the publication of the first edition in 1992, the bleaching process has continued to attract the attention of researchers and the edible-oil industry. In this second edition, readers are directed to modern techniques of trace-metal analysis, including flame-atomic adsorption, graphite furnace atomic adsorption, and atomic emission spectrometry involving direct current plasma (DCP) and inductively coupled Plasma (ICP). The book discusses the Freundlich Equation and reports on high-temperature water extraction, high- temperature oxidative aqueous regeneration, and extraction with supercritical CO2. Various degumming methods improved over the past several decades are also discussed.
