This latest volume in the series entitled Liquid Chromatography of
Natural Pigments and Synthetic Dyes presents an overview of the
latest developments in the field while critically evaluating this
method of analysis and providing comparisons of the various liquid
chromatographic separation techniques that are currently available.
Natural pigments and synthetic dyes are extensively used in various
fields of everyday life including food production, textile
industry, paper production, agricultural practice and research and
water science and technology. Besides their capacity for increasing
the marketability of products, natural pigments have shown
advantageous biological activity as antioxidants and anticancer
agents. On the negative side, synthetic pigments have a significant
impact on the environment and can cause adverse toxicological side
effects. Both pigment classes exhibit considerable structural
diversity. As the stability of the pigments against hydrolysis,
oxidation and other environmental and technological conditions is
markedly different, the exact determination of the pigment
composition may help for the prediction of the shelf-life of
products and the assessment of the influence of technological steps
on the pigment fractions resulting in more consumer friend
processing methods. Furthermore, the qualitative determination and
identification of the pigments may contribute to the establishment
of the provenance of the product. The unique separation capacity of
liquid chromatographic (LC) techniques makes it a method of
preference for the analysis of pigments in any complicated
accompanying matrices.
* an overview of the latest developments in the field
* a critical evaluation of results from this form of analysis
* a comparison of the various LC (liquid chromatographic)
separation techniques
* future trends in the LC analysis of pigments
Cyclodextrins can form complexes with a wide variety of organic and
inorganic compounds, a property which can prove useful when trying
to separate complex mixtures. This book provides an up-to-date and
critical evaluation of the application of cyclodextrins in many
fields of chromatography (including thin layer, gas-liquid, high
performance liquid and supercritical fluid chromatography;
capillary electrophoresis; and isotacophoresis). Whilst mainly
practical in nature, the book also looks briefly at the theoretical
background for the various techniques. Any professional working
with chromatography will welcome this unique book as both a
practical compilation of methods and a source of reference to the
literature regarding the use and impact of cyclodextrins in
chromatography.
The quantity and composition of aroma and avour compounds in foods
and food products exert a marked in uence on the consumer
acceptance and, consequently, on the commercial value of the
products. It has been established many times that one of the main
properties employed for the evaluation of the product quality is
the avour, that is, an adequate avour composition considerably
enhances the m- ketability. Traditional analytical methods are
generally unsuitable for the accurate determination of the quantity
of this class of compounds. Moreover, they do not contain any
useful information on the concentration of the individual
substances and they are not suitable for their identi cation. As
the stability of the aroma compounds and fragrances against
hydrolysis, oxidation and other environmental and tech- logical
conditions shows marked differences, the exact determination of the
avour composition of a food or food product may help for the
prediction of the she- life of products and the assessment of the
in uence of technological steps on the aroma compounds resulting in
more consumer-friendly processing methods. Furthermore, the
qualitative determination and identi cation of these substances may
contribute to the establishment of the provenance of the product
facilitating the authenticity test. Because of the considerable
commercial importance of avour composition, much effort has been
devoted to the development of methods suitable for the separation
and quantitative determination of avour compounds and f-
grancesinfoodsandinotherindustrialproducts.
oCompilation and evaluation of the newest applications of
chromatography for food science and technology oEnumeration of
chromatographic methods and critical discussion of results This
book presents a unique collection of up-to-date chromatographic
methods for the separation and quantitative determination of
carbohydrates, lipids, proteins, peptides, amino acids, vitamins,
aroma and flavor compounds in a wide variety of foods and food
products. Chromatography in Food Science and Technology presents a
concise evaluation of existing chromatographic methods used for
many food and food product macro and microcomponents.
Chromatographic methods are compiled according to the character of
the food components to be separated. The book's chapters deal
separately with the different classes of food components,
presenting both gas and liquid chromatographic methods used for
their determination, and discussing the advantages and
disadvantages of each. Unlike other references, Chromatography in
Food Science and Technology is entirely devoted to the use of
chromatography for food analysis, and focuses on practical,
food-related examples. It treats the theoretical aspects of
chromatography briefly, to the degree that the information helps
the use and development of new analytical methods for the
separation of any kind of food components.

Chromatography has been developed as a powerful and rapid technique
for the separation of compounds with highly similar molecular
characteristics, even from complicated matrices. Due to their
excellent separation characteristics and versatility,
chromatographic methods have found growing acceptance and
application in environmental protection for residue analysis in
air, ground and surface waters, sewage, sludge, and soil matrices.
This is a compilation and concise evaluation of results in this
rapidly developing domain of chromatography, with a brief
enumeration of the methods applied and a critical discussion of the
results. The book gives gas-liquid, thin-layer, high-performance
liquid, supercritical fluid chromatographic and capillary
electrophoretic analysis of pollutants belonging to different
compound classes. The book should be of interest to analytical
chemists in legalisation and research, and analytical control
specialists, as well as researchers and students.
