Abstract

Biodegradable capsules which consisted of recycled paper fibers as matrix material and limonene as core material were prepared by the simple nozzle method. Methyl cellulose was used as a binder of matrix fiber. Capsules were prepared by gelling methyl cellulose with tannic acid.<br>It was investigated how such preparing conditions of capsules as the concentrations of methyl cellulose and fibers affected a few characteristics of capsules. It was found that the structure, mechanical strength and water absorbed and drying properties were strongly dependent on the preparing conditions.
