E1204 – Pullula
ThickenerDescription
Polysaccharide produced by fermentation of Aureobasidium pullulans; functions as a thickener, stabilizer, and film-forming agent
Notes
Pullulan is a natural polysaccharide (a type of carbohydrate made of many sugar units linked together) that's produced through fermentation. It's created when a specific type of yeast-like fungus called Aureobasidium pullulans feeds on simple sugars like glucose or starch. During this fermentation process, similar to how yeast makes bread rise or creates alcohol, this microorganism produces pullulan as a byproduct. The resulting substance is then harvested, purified, and dried into a powder. As a food additive, pullulan serves as an excellent film-forming agent and coating material. It creates transparent, edible films that are particularly good at blocking oxygen, which helps keep foods fresh longer. You'll find it used to coat fresh-cut fruits and vegetables to extend their shelf life, as well as in supplement capsules as an alternative to traditional gelatin capsules. It's also used in some confectionery products and as a binding agent in various processed foods. Pullulan is completely natural and suitable for vegetarians, vegans, and people following halal or kosher diets, since it's produced by fermentation rather than from animal sources. This makes it particularly valuable as a replacement for gelatin in capsules and coatings. It's generally recognized as safe by food authorities and is well-tolerated by most people, with no common allergens associated with its production.
