Pullulan — Food Grade

Pullulan is a fermentation-derived polysaccharide from Aureobasidium pullulans that forms clear, low-oxygen-permeability films. It is used for capsule shells, edible films and coatings rather than as a viscosity builder.

Pullulan solutions stay low in viscosity at concentrations where other hydrocolloids gel, which is exactly why it casts clear films. Specifying it as a gum replacement for texture will not deliver the viscosity expected.

Pullulan films absorb moisture and soften at high relative humidity, which shows up as tacky capsules or strips. Confirm packaging and storage humidity before committing to the format.

Grades differ in molecular weight and therefore in film strength and dissolution rate. State the intended film thickness and dissolution target so the correct grade is quoted.

Permitted use, permitted level and required labelling for this material differ by country, by product category and by intended claim. Allzone does not represent that the material is approved for your application in your market. Tell us the destination market and the finished-product category, and the available supplier documentation is provided so your regulatory team can complete its own assessment.

Assay, particle size, solvent residue, microbiological limits and heavy-metal limits differ between producers and grades. Allzone confirms the applicable specification with the supplier before quoting and shares the technical data sheet, safety data sheet and certificate of analysis for the exact material offered, so the values you evaluate are the values you receive.
