Comparing E1204 - Pullulan vs E1521 - Polyethylene glycol

Overview

E1204 - Pullulan

Pullulan (E1204) is a natural polysaccharide made by fermentation. In food, it is used mainly as a film-former and thickener, creating clear, flexible coatings and quick-dissolving sheets. You’ll most often see it in edible glazes, confectionery, and breath-freshening strips.

E1521 - Polyethylene glycol

Polyethylene glycol (PEG) is a smooth, water‑soluble polymer used in small amounts to coat, carry, or dissolve other ingredients. In food, it appears as E1521 and helps give tablets and dragees a clean, glossy finish while keeping moisture under control. Regulators in the EU allow it for defined uses and set strict purity rules.

Popular questions

  1. What is pullulan capsule?

    A pullulan capsule is a plant-based, gelatin-free capsule shell made from pullulan (E1204), a polysaccharide produced by fermenting starch with the fungus Aureobasidium pullulans; it’s clear, tasteless, and has very low oxygen permeability to help protect sensitive ingredients.

  2. Pullulan what is it?

    Pullulan (E1204) is a polysaccharide made by fermenting starch with Aureobasidium pullulans, used in foods and supplements as a film-former and thickener, including for edible films and capsule shells.

  3. What are pullulan capsules made of?

    Primarily pullulan polymer derived from fermented starch, plus water; manufacturers often add small amounts of gelling agents (such as gellan gum) and plasticizers like glycerin or sorbitol to form the shell.

  4. What is organic pullulan?

    Organic pullulan is pullulan produced via fermentation using organic-certified substrates and processes that meet organic standards (e.g., USDA/EU) and is used to make organic-labeled edible films and capsule shells.

  5. What is a pullulan capsule?

    A pullulan capsule is a vegetarian capsule shell made from pullulan (E1204) instead of animal gelatin, offering a clear, tasteless shell with strong oxygen-barrier properties for supplements.

  1. How polyethylene glycol 3350 works?

    It’s an osmotic laxative that holds water in the stool and colon, softening stools and increasing bowel movements; it’s minimally absorbed and typically works within 1–3 days.

  2. Polyethylene glycol 3350 para que sirve?

    Es un laxante osmótico para el estreñimiento ocasional: retiene agua en el intestino para ablandar las heces y facilitar la evacuación (suele actuar en 1–3 días).

  3. Polyethylene glycol 3350 how to use?

    Dissolve 17 g (about one capful) in 4–8 oz of liquid and take once daily for up to 7 days unless your clinician advises otherwise. Stay well hydrated and avoid use if you have severe abdominal pain, bowel obstruction, or persistent symptoms; consult a clinician for children.

  4. What is polyethylene glycol used for?

    In foods and supplements, polyethylene glycol (E1521) is used as a carrier/solvent and film-forming or glazing agent; in medicine, certain grades (like PEG 3350) are used as osmotic laxatives for occasional constipation.

  5. Polyethylene glycol para que sirve?

    En alimentos y suplementos, el PEG (E1521) se usa como vehículo/solvente y agente de recubrimiento; en medicina, algunas formas (p. ej., PEG 3350) se usan como laxantes osmóticos para el estreñimiento ocasional.
