Abstract

Microcapsules having a carotenoid content of between about 10% and 50% by weight. A crystalline form of one or more carotenoids is processed in a fluidized bed coating machine where a protective coating of a sugar or polyhydric alcohol, a starch, and optionally a protein, is applied. The carotenoid content of the finished microcapsules is in excess of 80% of the carotenoids present in the starting material.
