Abstract
In a microcapsule of the multi-core structure comprising a plurality of particles which are made of a core material comprising natural carotenoid and an edible oil, and a wall which is made of a coating material based on gelatin, the particles have a mean particle size of 0.01-5 .mu.m, the gelatin has a jelly strength of at least 100 blooms, and the microcapsule has a water content of up to 10% by weight. The microcapsule has a strength enough to protect natural carotenoid from oxidation and deterioration for a long time and to withstand tableting pressure.
