Development of blueberry () waste powder as a potential food ingredient with functional properties.

Salta province, northwestern Argentina, produces blueberries for export and discards fruits with a potential quantity of bioactive compounds. These bioactive compounds have health-promoting properties that prevent or delay the appearance of chronic diseases. This study aimed to formulate blueberry microcapsules using discarded fruit, to determine and evaluate the effect of spray-drying and lyophilization on the bioactive compounds and their physical properties.
