Abstract: The talk will be an overview of the chemistry of food oligo- and polysaccharides object of study at the University of Aveiro, in Portugal. Examples will be the transglycosylation reactions promoted during the roasting of coffee and baking of bread. These reactions also occur in honey. Focus will be also on brewer’s yeast polysaccharides, which are modified along fermentation, allowing to obtain spent yeast polysaccharides with different characteristics and properties, opening potential differentiated applications. Examples of challenges from food industry will be provided, namely, to have wines and vinegar free of sulfur dioxide, microwavable puff pastry, non-thickening flavoring ingredients from Cinnamomum cassia, and polysaccharides from salt pan brine water with immunostimulatory activity. To finish, the Ecotrophelia Euro 2020 winner product, OrangeBee, is introduced, as well as the Ecotrophelia Europe 2022 Portuguese representant, Handy Rice.
