Abstract
An opacity modifying agent in dry particulate form as an alternative t titanium dioxide is described herein. The opacity modifying agent may comprise a calcium salt encapsulated in a water-insoluble protein matrix via extrusion encapsulation, leading to the encapsulated calcium salt having higher opacity than that of the unencapsulated calcium salt. In embodiments, the opacity modifying agent may comprise calcium carbonate encapsulated in an alkaline rice protein extract having a whiteness approaching that of calcium carbonate. Processes for producing the opacity modifying agents, as well as their uses in food, cosmetic, or personal care products are also described herein.
