  3. How do they make propylene glycol alginate?

    Manufacturers extract alginic acid from brown seaweed, purify it, then partially esterify it with propylene glycol under controlled conditions. The material is then neutralized as needed, dried, and milled into a powder.

  4. How is propylene glycol alginate made?

    By partially esterifying seaweed-derived alginic acid with propylene glycol, leaving some carboxyl groups free or neutralized with alkali, then drying the product. This process yields an emulsifier, stabilizer, and thickener used in foods.

  5. An e-code from category e990 – e999 would be reported in which of the following circumstances?

    When a product contains one of these ‘miscellaneous’ additives and must list it on the ingredient label; for example, E999 appears on permitted soft drinks or desserts where it’s used as a foaming/humectant agent.
