Is it safe? Side effects & regulation

Sort food additives by:



Tag: GREEN

  • E524 – Sodium hydroxide

    E524 – Sodium hydroxide

    E524 sodium hydroxide is an alkalizing and pH-control additive used in foods such as olives and pretzels. It is GREEN - SAFE after correct processing, but concentrated lye is highly corrosive.

  • E337 – Potassium sodium tartrate

    E337 – Potassium sodium tartrate

    E337 potassium sodium tartrate, also called Rochelle salt, is a stabiliser and acidity regulator graded GREEN - SAFE at normal permitted food-use levels.

  • E957 – Thaumatin

    E957 – Thaumatin

    E957 thaumatin is an intensely sweet plant protein used as a sweetener and flavour enhancer. Evidence supports a GREEN - SAFE grade, although rare oral allergy remains uncertain.

  • E507 – Hydrochloric acid

    E507 – Hydrochloric acid

    E507 hydrochloric acid is a food acidity regulator and pH control agent. It is generally low concern in regulated food use, but concentrated acid is corrosive.

  • E335 – Sodium tartrates

    E335 – Sodium tartrates

    E335 sodium tartrates regulate acidity and texture in foods. They are GREEN - SAFE at normal use, but high doses add sodium and a mouse study raises an indirect gut-immune concern.

  • E334 – Tartaric acid

    E334 – Tartaric acid

    E334 tartaric acid controls acidity and adds a sharp sour taste to foods and drinks. Food-grade L(+)-tartaric acid is GREEN - SAFE at permitted use levels.

  • E464 – Hydroxypropyl methyl cellulose

    E464 – Hydroxypropyl methyl cellulose

    E464 hydroxypropyl methyl cellulose thickens and stabilizes foods and forms vegetarian capsules. It is GREEN - SAFE at food levels, with high-dose digestive, rare allergy and impurity caveats.

  • E999 – Quillaia extract

    E999 – Quillaia extract

    E999 quillaia extract is a plant-derived foaming agent used mainly in drinks. Long-term animal studies are reassuring, while concentrated high doses can irritate the digestive tract.

  • E332 – Potassium citrates

    E332 – Potassium citrates

    E332 potassium citrates regulate acidity and stabilise foods and drinks. They are considered safe at normal food-use levels, with caution mainly for high supplemental potassium doses.

  • E470a – Sodium, potassium and calcium salts of fatty acids

    E470a – Sodium, potassium and calcium salts of fatty acids

    E470a covers sodium, potassium and calcium salts of fatty acids used as emulsifiers, stabilisers and anti-caking agents. It is GREEN - SAFE at normal food-use levels, with practical cautions about variable plant or animal source materials and food-grade impurity specifications.

  • E570 – Fatty acids

    E570 – Fatty acids

    E570 fatty acids are food-grade fatty acids used as release agents, lubricants, defoamers and coating aids. They are generally safe at permitted use levels.

  • E535 – Sodium ferrocyanide

    E535 – Sodium ferrocyanide

    E535 sodium ferrocyanide is an anti-caking agent used in salt. It is generally safe at permitted levels, with kidney-related caution only at much higher exposure.

  • E508 – Potassium chloride

    E508 – Potassium chloride

    E508 potassium chloride is a mineral salt used as a salt replacer, flavor enhancer and pH control agent. It is GREEN - SAFE for most people at normal food-use levels, with caution for kidney disease and high-potassium salt substitutes.

  • E420 – Sorbitols

    E420 – Sorbitols

    E420 sorbitols include E420(i) sorbitol and E420(ii) sorbitol syrup, sugar alcohol sweeteners and humectants with a GREEN - SAFE grade but notable laxative effects at high intake.

  • E476 – Polyglycerol polyricinoleate

    E476 – Polyglycerol polyricinoleate

    E476 polyglycerol polyricinoleate, also called PGPR, is an emulsifier used mainly in chocolate, coatings, edible ices, and fatty sauces. Evidence is generally reassuring at normal intake, with high-dose liver and kidney weight changes interpreted as adaptive rather than harmful.

  • E1520 – Propylene glycol

    E1520 – Propylene glycol

    E1520 propylene glycol is used mainly as a solvent, carrier and humectant in flavourings, colours and other food preparations. It is graded GREEN - SAFE at normal food-use levels, with caution for unusually high intake.

  • E514 – Sodium sulphates

    E514 – Sodium sulphates

    E514 sodium sulphates covers sodium sulfate and sodium hydrogen sulfate, acidity regulators used in some processed foods. They are generally considered safe at normal food-use levels, but high intake can loosen stools or irritate sensitive stomachs.

  • E331 – Sodium citrates

    E331 – Sodium citrates

    E331 sodium citrates are used as acidity regulators, buffers, and emulsifying salts. They are generally safe at normal food-use levels, with caution mainly for high supplemental intake or sodium restriction.

  • E261 – Potassium acetate

    E261 – Potassium acetate

    E261 potassium acetate is an acidity regulator and preservative from the acetate family. It is generally considered low risk at normal food-use levels, though very high intake may irritate the stomach and matters more for people who must limit potassium.

  • E336 – Potassium tartrates

    E336 – Potassium tartrates

    E336 potassium tartrates, including monopotassium tartrate and dipotassium tartrate, are acidity regulators generally considered safe at normal food-use levels.
