Carbohydrate composition, in vitro digestion, and effects of xylanase and phytase on nutrient and energy digestibility by pigs in grains and grain coproducts
Four experiments were conducted to determine carbohydrate composition, in vitro digestion, and effects of xylanase and phytase on ileal and total tract digestibility of nutrients and energy in grains and grain coproducts. The objective of Exp. 1 and Exp. 2 was to determine the efficacy of xylanase …

Characterising the techno- and bio-functional properties of milk protein-polyphenol complexes for application in performance nutrition
There is increased consumer interest in performance nutrition, focusing especially on enhancing muscle strength and recovery. Dairy-plant hybrid beverages, rich in milk proteins and polyphenols, have considerable potential in this area, because both proteins and polyphenols have been positively …

Influence of Physiological State, Prolonged Dry Storage, and Passage through Simulated Digestion on the Survival and Gene Expression of Salmonella enterica sv. Tennessee
Salmonella enterica serotypes have been linked to outbreaks associated with low water activity foods. The ability of biofilm forming pathogens, such as Salmonella, to survive thermal and chemical processes is improved; it is unclear if biofilms will also improve survival to desiccation and gastric …
