Is sugar vegan? Bone char, beet sugar and what to check

Published , updated

Sugar is plant-derived, yet it is one of the most debated ingredients among vegans. The reason is not the sugar itself but a step in how some of it is refined. Some cane sugar is decolourised using filters made of bone char, which comes from animal bones. It does not appear in the finished sugar, and nothing on the ingredient label tells you whether it was used. This guide explains what is known, which types of sugar are less likely to be affected, and how to find out about a particular brand, without claiming more certainty than the facts allow.

What bone char is and why it is used

Raw cane sugar is brown and contains impurities. To make white sugar, refiners remove colour. One method is to pass sugar syrup through filters of granular carbon. Some refiners use bone char, a carbon made by heating animal bones, usually cattle bones, at high temperature. Others use activated carbon from plant sources, ion exchange resins or other methods.

Bone char is a processing aid. It is not an ingredient in the sugar, and it is not added to the product. Because of that, it does not have to be listed on the label, so the pack cannot tell you whether it was used. Some vegans avoid sugar processed this way because animal products were part of making it, and others do not mind. That choice is yours.

Where it applies and where it does not

Practice varies by country and by refiner, and it can change over time. Bone char use is most often discussed in connection with cane sugar refined in the United States. Refiners elsewhere often use other methods, but we cannot give a reliable list for every country, so use brand statements rather than assuming.

Sugar types and bone char
SugarWhat is commonly saidWhat to do
Beet sugarSugar beet refining is generally described as not using bone charUsually a safe choice; check if the pack says only sugar and the source
Cane sugar, white or granulatedMay or may not have been filtered with bone char depending on refinerCheck the brand's statement or contact the maker
Certified organic sugarCommonly sold as an option for avoiding bone charConfirm with the brand; rules differ by certifier and country
Sugar labelled vegan or certified veganBrand is making a vegan claim, often verified by a certifierCheck which certification mark it carries
Raw, demerara, turbinado, muscovadoLess refined; often not decolourised in the same wayCheck the brand, because not all are the same
Brown sugarOften refined white sugar with molasses added backTreat like white sugar of the same brand
Icing sugar (powdered)Made from refined sugar, with added starch to prevent cakingSame as the sugar it came from; any anti-caking agent is usually a starch such as corn or tapioca, or a mineral; check the label for gluten-free needs

How to check a brand

  1. Read the front and back of the pack for a vegan label or a certification mark such as a vegan trademark. Organic and vegan certifications each have their own standards, so look up what the scheme requires.
  2. Check the brand's website for a frequently asked questions page; many sugar brands state their processing method.
  3. If nothing is clear, email or phone the company and ask whether bone char is used in refining, in the factory that made your pack. Brands can source from different refineries at different times.
  4. Record the answer by brand and product; it may change.

Other sugars and sweeteners

Honey is made by bees and is not vegan. Maple syrup, agave syrup, date syrup and rice syrup are plant-derived. Coconut sugar and date sugar are produced from plant sap or fruit and are not usually filtered through bone char, though the same advice applies: check the brand if it matters to you. Molasses is a by-product of sugar refining and is plant-derived, but check the processing of the particular product if the question matters to you.

Sugar-heavy decorations raise separate issues. Some sprinkles, glazes and coloured sugars use shellac, which comes from the lac insect, or carmine, a red colour made from insects, or gelatin. These do appear on ingredient labels, so read them.

Does it matter in baking?

In the kitchen, sugar refined with or without bone char behaves the same way. Bone char does not change flavour, sweetness or how sugar browns and dissolves. The difference is purely a matter of values and what a given brand does. If you cook for others, tell them which sugar you used if it matters to them. If you are converting a recipe, our conversion guide covers the usual animal ingredients; sugar is the one that needs a label check rather than a swap.

If you bake gluten free and vegan, note that sugar itself is naturally gluten free, but flavoured, powdered and decorative sugars can include additives. Read the label and, for coeliac needs, ask a doctor or dietitian.
