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.
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.
