How long has pullulan been in use in foods?

The first use of pullulan was reported in 1938. Commercial production of pullulan began in Japan in 1976. The raw material is non-GMO and is prepared under a patented manufacturing process. One of the first commercial successes was the use of pullulan in pocket-pack strips. Capsugel started development of a pullulan capsule in the late 1990's. A first generation pullulan capsule was introduced in 2003 in the dietary supplement industry. Capsugel introduced the second generation pullulan capsule in 2012 with a new patented formula. The second generation pullulan used tapioca as the root source which provided more robust mechanical properties.
