• Sommario/riassunto: Following significant developments in recent understanding of milk systems and an explosion in interest in the use of probiotics and prebiotics as functional foods Probiotic Dairy Products looks at advancements in the dairy industry and reviews the latest scientific developments in regard to the 'functional' aspects of dairy and fermented milk products and their ingredients. The first title in Blackwell Publishing's prestigious Society of Dairy Technology Series, this key text includes coverage of:Production systemsGut microfloraGenomic characterisation of probiot
