  • Patent number: 10899849
    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.
    Type: Grant

  • Patent number: 10894971
    Abstract: A method for the production of pullulan soft capsules eliminates 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 soft capsule production to provide a unique approach for soft capsule formation. The purified pullulan fermentation fluid can be directly used in soft capsule preparation, thus removing the need for a melting process. On the one hand, the method can decrease material consumption, save the cost of equipment and labor, reduce production time and increase productivity. On the other hand, the method can reduce the fluctuating of raw material quality in the re-melting process and guarantee a more stable soft capsule production and quality.
