Abstract
A method for the production of empty pullulan capsules eliminate the need to dry pullulan solid product, thereby reducing the equipment cost and energy consumption. The pullulan raw material production can be linked directly with the capsule production to provide a unique approach for empty capsule formation. The purified pullulan fermentation fluid can be directly used in capsule preparation, thus removing the need for a melting process. On the one hand, the method may decrease material consumption, save the cost of equipment and labor, reduce production time and increase productivity. On the other hand, the method may reduce the fluctuating of raw material quality in the re-melting process and guarantee a more stable capsule production and quality.
