Modern tendencies of healthy nutrition include widening of the choice of foodstuffs
balanced in composition and capable of solving a number of preventive tasks. Prebiotics are
the most prospective components of functional foodstuffs [1, 2]. Prebiotics provide
favourable conditions for the multiplication and metabolic activity of lacto- and bifidus
bacteria in the large intestine. Besides they can excrete toxins and improve liver functioning
[3,4].
It is now well established that the colonic microflora has a profound influence on health.
Consequently, there is currently a great deal of interest in the use of prebiotic as functional
food ingredients to manipulate the composition of colonic microflora in order to improve
health. Functionally, the human colon undertakes a number of important physiological
activities. However, another extremely significant metabolic trait is mediated by gut bacteria.
The human embryo is virtually sterile, but at birth microbial colonisation of the
gastrointestinal tract occurs, with the neonate receiving an inoculum from the birth canal.
During the acquisition period, some bacteria transiently colonise the gut whilst others survive
and grow to form the indigenous microflora. Microorganisms occur along the whole length of
