Pullulan is an extracellular water-soluble viscous polysaccharide, similar to glucan and xanthan gum, produced by the fermentation of Aureobasidium pullulans. It was discovered as a unique microbial polysaccharide in 1938.
Food Preservative
An aqueous solution of pullulan exhibits excellent film-forming properties. The resulting film is glossy, transparent, flexible, highly stable under temperature variations, and offers good heat-sealing characteristics. It also acts as a barrier against gases, preserves aroma, resists oil, and provides electrical insulation.
1. Application in Fruit Preservation
Apples and citrus fruits are perishable and not suitable for long-term storage. Conventional refrigeration methods often yield unsatisfactory results. Pullulan is non-toxic, odorless, and poses no adverse effects on human health, making it an ideal coating for fruit preservation. Studies have also shown that pullulan itself does not possess bactericidal or bacteriostatic properties.
2. Application in Egg Preservation
When refrigeration is inadequate, eggs are often coated with paraffin or liquid paraffin for preservation, though the effectiveness is limited. Using pullulan or its esters as a coating material can extend the shelf life of eggs at room temperature, enhance shell strength, and reduce breakage caused by impact. Pullulan is edible and can be easily removed with cold or warm water.
3. Application in Vegetables and Dried Fruits
An emulsion composed of pullulan and other hydrophobic substances serves as a highly effective preservative coating for vegetables. For instance, podded broad beans turn black after 2–3 days at 25°C, but when coated, they remain green for up to 14 days—extending their shelf life fivefold. Applying an extremely thin pullulan film to oil-rich foods such as peanuts, walnuts, almonds, legumes, dried fish and shellfish, as well as dried potato strips and radishes, can effectively prevent oxidation.
4.Application in Seafood Preservation
As a novel coating preservative for seafood, pullulan effectively inhibits moisture evaporation, suppresses the production of volatile basic nitrogen, and reduces oxidative loss of nutrients, thereby preserving the original flavor of seafood.
