Large diameter legume starch granules including starches derived from yellow field pea, Pisum sativum (var) and faba bean, Vicia faba L. (Leguminosae) which have been treated to remove protein and fiber, and to improve color are used to replace scarce arrowroot starch granules as a protective stilt material in microencapsulated coatings, including carbonless copy paper. The "stilt" material is used to prevent premature rupture of the microcapsules and early release of the microencapsulated materials. It has been discovered that the natural granule size, and other granule properties of the yellow field pea and faba bean starches are ideally suited to replace arrowroot starch granules as a protective material when the naturally occurring protein and fiber have been removed, and the color improved.
