Countercurrent chromatography (CCC) is a separation technique in which the stationary phase is a liquid. The mobile phase is also a liquid, so biphasic liquid systems with at least two solvents are used. Centrifugal fields are used to hold the liquid stationary phase while pushing the liquid mobile phase through it. This comprehensive reference covers recent advancements in the two types of CCC machines: the high speed CCCs without rotary seals and with coiled spools and centrifugal partition chromatographs (CPC) with rotary seals and interconnected channels. Written by leading international experts in the CCC field, the book focuses on the liquid nature of the stationary phase: giving newcomers the basis to do CCC efficiently and rapidly; explaining the art of obtaining a biphasic liquid system; describing the flow patterns in both CPC and high speed CCC machines; showing possible other uses of a liquid stationary phase; presenting a wealth of applications in the separation of organic, pharmaceutical and inorganic mixtures; and demonstrating that even supercritical fluids can be used in CCC.

Bioactive ingredients in foods and their pharmacological and health effects. Functional foods and bioactives of microbial, plant and animal origin, including probiotics, herbs, spices, vegetables, specialty fruits, seafood and milk components. Impact on the microbiome, emerging metabolic pathways and prevention of chronic and infectious diseases.Techniques for functional food development and evaluation.Regulatory and safety considerations. This volume presents basic and advanced technical information on the sources, mechanisms and safety of food bioactives in the etiology and prevention of chronic and infectious diseases. In this context, it offers details useful not only for understanding but also improving the functionality of foods. It reviews advances in multiple phytochemicals and food ingredients known for positive effects on human physiology, including interactions with the human microbiome. Metabolomic and proteomic techniques are explored as ways of improving the understanding of mechanisms of action, and increasing the therapeutic effectiveness of selected food ingredients. Special attention is given to chemistry, molecular structure and pharmacological effects of bioactive ingredients. Bioactives from a wide range of foods are investigated, including pro- and prebiotics, fungi, yeasts, herbs, spices, fruits, vegetables, seafood and many more. The text provides systematic information needed to develop and validate commercial products incorporating functional ingredients.
