Method for the production of pullulan capsules

A method for the production of pullulan capsules, comprising:

• fermenting Aureobasidium pullulans to produce a pullulan fermentation liquor;
• filtering the fermentation liquor through at least one of a plate and frame press filter and an ion exchange column;
• concentrating the fermentation liquor;
• transferring the concentrated fermentation liquor into a gel storage tank maintaining a temperature from about 40° C. to about 70° C.;
• pumping the concentrated fermentation liquor from the gel storage tank into a transfer tank to form a capsule gel liquid, the capsule gel liquid having pullulan with a molecular weight suitable for the production of the capsule;
• and
• forming the pullulan capsule from dipping a mold into the capsule gel liquid, wherein the method lacks drying the pullulan to form a solid pullulan product.

A pullulan capsule produced by a process comprising:

• fermenting Aureobasidium pullulans to produce a pullulan fermentation liquor;
• filtering the fermentation liquor;
• concentrating the fermentation liquor;
• transferring the concentrated fermentation liquor into a gel storage tank having a temperature control function;
• pumping the concentrated fermentation liquor from the gel storage tank into a transfer tank to form a capsule gel liquid, the capsule gel liquid having pullulan with a molecular weight suitable for the production of the capsule;
• and
• forming the pullulan capsule from dipping a mold into the capsule gel liquid, wherein the process lacks drying the pullulan to form a solid pullulan product.
