Pectin
A natural fibre extracted from citrus peel and apple pulp, used to set jams, thicken sauces, and stabilise drinks.
What is it?
Pectin is a naturally occurring polysaccharide (a complex carbohydrate) found in the cell walls of most fruit and vegetables. Commercially it is extracted mainly from citrus peel and apple pomace, the pulp left after juicing. Two forms are authorised: conventional pectin (E440i) and amidated pectin (E440ii), which has been chemically modified to gel under a wider range of conditions. Both are structural plant fibres with a long history of household and commercial use.
What does it do?
Pectin forms a gel when it encounters water, sugar, and acid. In processed food this property is used to set jams and preserves, thicken fruit preparations, and stabilise emulsions and drinks. The gelling strength can be controlled by the degree of esterification in conventional pectin, or by the amidation level in E440ii. It also functions as a soluble dietary fibre once it reaches the gut, where it is fermented by colonic bacteria.
Where you will see it
Found most commonly in jams, marmalades, jellies, fruit preparations in yoghurt, fruit-flavoured drinks, confectionery jellies, low-fat spreads, and some sauces and soups. Baby food and infant formula use tightly controlled limits. On a UK label it appears as 'pectin', 'E440', 'E440i' (conventional), or 'E440ii' (amidated).
What the science says
Prebiotic and gut microbiome effects
Pectin reaches the large intestine largely undigested and is fermented by gut bacteria into short-chain fatty acids such as butyrate. Butyrate is the main fuel source for the cells lining the colon and is associated with a healthy gut environment. Multiple human intervention trials have shown that pectin supplementation increases populations of beneficial bacteria including Bifidobacterium and Lactobacillus species. This is a well-characterised property of soluble dietary fibre rather than a concern.
Pectin is rapidly fermented in the human colon, producing short-chain fatty acids including butyrate, and selectively stimulates beneficial Bifidobacterium and Lactobacillus populations in human volunteers.
EFSA's 2017 re-evaluation concluded that the fermentability and prebiotic properties of pectin are well established and present no safety concern for the general population.
Infant formula and young infants
The 2017 EFSA re-evaluation left open one specific question: whether pectin at current permitted levels is appropriate in foods for infants below 16 weeks of age. EFSA published a supplementary opinion in January 2021 (EFSA Journal 2021;19(1):6387). That opinion found that at the then-current maximum permitted levels, the internal methanol dose produced by pectin metabolism could lead to adverse effects in infants below 16 weeks, and recommended a reduction in the maximum permitted level in two specialist infant food categories (dietary foods for special medical purposes for infants, and dietary foods for babies and young children for special medical purposes). The 2021 opinion confirmed no safety concern and no change to the authorisation for the general population.
EFSA's 2021 supplementary opinion found that at current maximum permitted levels pectin could produce an internal methanol dose of potential concern in infants below 16 weeks, and recommended a reduction in the maximum permitted level in food categories FC 13.1.5.1 and FC 13.1.5.2. No safety concern was identified for any other population group.
Cholesterol and glycaemic response
A number of controlled trials and meta-analyses have found that regular pectin intake modestly lowers LDL cholesterol and blunts post-meal blood glucose rises. These are effects of soluble dietary fibre in general and are not unique to pectin as an additive. The European Commission has authorised a health claim that pectin contributes to the maintenance of normal blood cholesterol levels when at least 6g per day is consumed as part of a meal.
A meta-analysis of 67 controlled trials found that viscous soluble fibres including pectin significantly reduced LDL cholesterol compared with controls, with a pooled reduction of around 0.2 mmol/L.
EFSA authorised a health claim for pectin on maintenance of normal blood cholesterol levels at a use level of 6g per day.
Where it stands with the regulators
Who should be careful
No population group needs to avoid pectin. Very high supplemental doses (well above typical food additive levels) can cause digestive discomfort in people sensitive to fermentable fibres. People following a low-FODMAP elimination diet sometimes reduce high-pectin fruits but this relates to whole-food fibre content, not trace additive levels. Look for 'pectin', 'E440', 'E440i', or 'E440ii' on labels if tracking fibre sources.
The honest read
Pectin is one of the most studied natural food additives and has been in continuous use for well over a century. Its chemistry and gut behaviour are thoroughly characterised: it is a plant fibre that ferments in the colon, and the principal effects documented in humans are the same beneficial ones associated with eating fruit. The only regulatory question that prompted follow-up work concerned a very specific sub-group: formula-fed infants below 16 weeks, where EFSA's 2021 opinion identified a potential methanol exposure concern at current maximum permitted levels in two specialist infant-food categories and recommended those limits be reduced. No concern was identified for any other population group. There is no IARC classification, no broad ban, no endocrine concern, and no allergen declaration requirement.

Common questions
Is E440 banned in the UK?
No. Pectin (E440i and E440ii) is fully approved for use in food in the UK under the FSA approved-additives list and assimilated EU Regulation 1333/2008.
Is E440 the same pectin I use to make jam at home?
Yes. Commercial food-grade pectin is chemically identical to what is sold in home-baking pectin sachets and the pectin naturally present in fruit. The 'i' and 'ii' suffixes distinguish the unmodified form (E440i) from a chemically amidated version (E440ii) that gels more reliably at low sugar levels.
What foods contain E440?
Jams, marmalades, fruit yoghurts and fruit preparations, fruit drinks and squashes, confectionery such as jellied sweets, low-sugar spreads, and some soups and sauces. It also appears in some baby foods. On a label it reads as 'pectin', 'E440', 'E440i', or 'E440ii'.
Is E440 vegan?
Yes. Pectin is extracted entirely from plant sources, primarily citrus peel and apple pomace. It contains no animal-derived ingredients.
