Effect of ultrasounds and ball milling on the bioaccessibility of carotenoids from the microalga Dunaliella bardawil

This study evaluated the bioaccessibility of carotenoids from wild-type and phytoene-enriched Dunaliella bardawil biomass treated by ultrasounds and ball-milling. Fresh, freeze-dried, and alginate-encapsulated matrices were studied. The impact of yogurt addition was also evaluated on freeze-dried sa...
