In this study we produced microcapsules using layer-by-layer adsorption of food-grade polyelectrolytes. The shell was built with alternating layers of ovalbumin fibrils and high methoxyl pectin. By varying the number of layers, the release of active ingredients can be controlled – increasing the number of layers of the shell from 4 to 8, decreases the release rate by a factor 3. The formation of the capsules involves merely standard operations that can easily be scaled up to industrial production.
