Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Quantification of lipids can be broadly classified into the following methods:
gravimetric analysis, which employs the principle of phase separation, the acid value is
based on the property of rancidity of fats, saponification value which relies on alkali
required to saponify (hydrolyze) lipids containing mixture, iodine value depends on the
interaction of fats with halogen iodine, and blood cholesterol estimation determines the
cholesterol level by cholesterol esterase enzyme-based assay. These assays have been
explained in detail in this chapter. Advanced techniques used for lipid quantification
utilize the principles of chromatography (Thin-layer chromatography, gas
chromatography, and HPLC) and spectroscopy (infrared spectroscopy, Raman
spectroscopy, nuclear magnetic resistance spectroscopy, and fluorescence
spectroscopy), and different colourimetric assays are discussed in detail in this chapter.
