Thus, to be effective, prebiotics must escape digestion in the upper gastrointestinal tract and be used by a limited number of the microorganisms comprising the colonic microflora. Prebiotics are principally oligosaccharides. They mainly stimulate the growth of bifidobacteria, for which reason they are referred to as bifidogenic factors. Probiotics are defined as live microorganisms, including Lactobacillus species, Bifidobacterium species and yeasts that may beneficially affect the host upon ingestion by improving the balance of the intestinal microflora. The dietary use of live microorganisms has a long history. Mention of cultured dairy products is found in the Bible and the sacred books of Hinduism. Soured milks and cultured dairy products, such as kefir, koumiss, leben and dahi, were often used therapeutically before the existence of microorganisms was recognized. The use of microorganisms in food fermentation is one of the oldest methods for producing and preserving food. Much of the world depends upon various fermented foods that are staples in the diet.a The aim of this project is to provide a comprehensive overview on the advances in the field. The two volumes present the science underpinning the probiotic and prebiotic effects, the latest in vivo studies, the technological issues in the development and manufacture of these types of products, and the regulatory issues involved. Each volume is structured so that it covers all aspects of the topics in a logical manner, avoiding replication. It is anticipated that this will be a useful reference for both scientists and technologists working in academic and governmental institutes, and the industry.
