How much is permitted
A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.

The two specifications, compared
The European Union sets identity and purity by regulation; JECFA publishes its own through FAO, advisory until a country adopts it. Both documents are below in full. These are the parameters each puts a number on.
| Parameter | European Union | JECFA |
|---|---|---|
| Assay | no less than 65 % | — |
| Loss on drying | no more than 12 % | no more than 12 % |
| Lead | no more than 0.3 mg/kg | no more than 2 mg/kg |
| Arsenic | no more than 0.1 mg/kg | — |
| Mercury | no more than 0.1 mg/kg | — |
| Cadmium | no more than 0.1 mg/kg | — |
One parameter differs between the two documents. A difference is not a disagreement about safety: the two are revised on their own cycles, and an assay or a drying loss can be measured against a different preparation of the substance, which is why only the contaminant ceilings are marked. Within the EU the EU's figure is the one that binds.
How the EU defines it
The legal specification an additive must meet to be sold as this E number in the EU — what it is, how it may be made, and the purity it must reach. From Commission Regulation (EU) No 231/2012.
E 440(i) Pectin
Pectin consists mainly of the partial methyl esters of polygalacturonic acid and their ammonium, sodium, potassium and calcium salts. It is obtained by extraction in an aqueous medium of strains of appropriate edible plant material, usually citrus fruits or apples. The final product must not show any residual enzyme activity. No organic precipitant shall be used other than methanol, ethanol and propan-2-ol.

How JECFA defines it
The international specification for identity and purity, prepared by the Joint FAO/WHO Expert Committee on Food Additives and published by FAO. It is a different document from any above, written by a different body and revised on its own cycle; it is advisory, and a country adopts it or does not.
INS 440 Pectins
Consists mainly of the partial methyl esters of polygalacturonic acid and their sodium, potassium, calcium and ammonium salts; obtained by extraction in an aqueous medium of appropriate edible plant material, usually citrus fruits or apples; no organic precipitants shall be used other than methanol, ethanol and isopropanol; in some types a portion of the methyl esters may have been converted to primary amides by treatment with ammonia under alkaline conditions. Sulfur dioxide may be added as a preservative. The commercial product is normally diluted with sugars for standardization purposes. In addition to sugars, pectins may be mixed with suitable food-grade buffer salts required for pH control and desirable setting characteristics. The article of commerce may be further specified as to pH value, gel strength, viscosity, degree of esterification, and setting characteristics.

- Specification history
- Prepared at the 82 nd JECFA (2016) and published in FAO JECFA Monograph 19 (2016) superseding specifications prepared at the 71 st JECFA (2009) and published in FAO JECFA Monographs 7 (2009). A group ADI “not specified” was established for pectins and amidated pectins, singly or in combination at the 25 th JECFA (1981).
- C.A.S. number
- 9000-69-5
- DESCRIPTION
- White, yellowish, light greyish or light brownish powder
- FUNCTIONAL USES
- Gelling agent, thickener, stabilizer, emulsifier
Identification
- Test for pectins
- Passes test See description under TESTS
- Test for amide group
- Passes test (amidated pectins only) Add 2 ml of concentrated hydrochloric acid and 50 ml of 60% ethanol to 0.5 g of the sample, and stir well for 20 min. Transfer to a fritted glass filter tube wash with six 10 ml portions of the HCl-60% ethanol mixture. Dissolve in 100 ml distilled water; it may be necessary to add a few drops 0.1 mol/L sodium hydroxide to achieve solution. Transfer 4 ml of this solution into a test tube (recommended dimensions 15.5 mm inner diameter and 146 mm length). Add 1 ml 5 mol/L sodium hydroxide and mix. The mixture will form a gel. Fill a small glass tube (recommended dimensions 7.8 mm inner diameter and 79 mm length) with 2.5 ml boric acid TS and let glide into the test tube. Close with parafilm and incubate overnight at 30°. In case of presence of amide groups the indicator changes its colour from red to green, due to release of ammonia.
- Test for Pectins
- Moisten 0.05 g of the sample with 2-propanol. Add 50 ml of water on a magnetic stirrer. Adjust pH to 12 using 0.5 mol/l sodium hydroxide and let the solution remain without stirring for 15 min. Reduce pH to 7.0 with 0.5 mol/l hydrochloric acid. Adjust to 100.0 ml with water. Make up samples in 1 cm quartz cuvettes as follows: Buffer Sample soln Water Enzyme soln **) pH 7.0 *) Enzyme blank 0.5 ml 1.0 ml 1.0 ml - Sample blank 0.5 ml - 1.5 ml 0.5 ml Sample 0.5 ml 1.0 ml 0.5 ml 0.5 ml *) Dissolve 6.055 g of tris(hydroxymethyl)aminomethane (e.g. TRIZMA Base, Sigma) and 0.147 g of calcium chloride dihydrate in water to 1 l. Adjust pH to 7.0 with 1 mol/l hydrochloric acid **) Dilute pure pectate lyase 1:100 with buffer pH 7.0 Shake the solutions well, and measure the absorbance at 235 nm at 0 and 10 min. Calculations A 0 = absorbance at 0 min = Sample - (enzyme blank + sample blank) A 10 = absorbance at 10 min = Sample - (enzyme blank + sample blank) The amount of unsaturated product produced is proportional to the change in absorbance (A 10 - A 0 ). This value should be greater than 0.023. This distinguishes pectins from other gums, which show essentially no change.

- Test: Sulfur dioxide
- Suspend 100 g of the sample in 500 ml of methanol in a 1000-ml round-bottom flask, which is provided with a gas inlet tube reaching almost the bottom and connected to the neck with a reflux condenser. Prepare a glass joint connection from the condenser to an absorption flask or U-tube containing 10 ml of 3% hydrogen peroxide solution neutralized to methyl red TS. Connect the gas inlet tube with an oxygen-free source of carbon dioxide or nitrogen, and maintain a gas stream so as to cause steady bubbling. As soon as the apparatus is flushed free of air, pour 30 ml of hydrochloric acid solution (10 ml conc. HCl + 20 ml H 2 O) into the reflux condenser, and immediately connect the absorption flask or U-tube. Heat slowly until methanol starts refluxing, and reflux gently for 2 h. Disconnect the apparatus and titrate the hydrogen peroxide solution against methyl red TS with 0.01 mol/l sodium hydroxide. Each ml of 0.01 mol/l sodium hydroxide corresponds to 0.32 mg of SO 2 .
- Test: Total insolubles
- Dry a 70 mm glass fiber filter paper (GF/B (Whatman code 1821 070) in an oven with fan set at 105° for about 1 h. Transfer the filter paper to a desiccator containing silica gel and allow to cool. Weigh the paper (M 1 ). Weigh about 1 g (= S) of the sample into a 250-ml beaker. Add 5 ml of 2-propanol to disperse the sample. While stirring magnetically, add 100 ml of 0.03 mol/l sodium hydroxide containing 0.1% (w/w) ethylene diamine tetra-acetic acid (Na salt), which has been filtered through GF/B paper. Stir for about 30 min at room temperature, then heat to boiling (remove heat if excessive foaming occurs). Filter the hot solution through the glass fiber paper under vacuum using, e.g. a vacuum filtration kit with 3 piece Hartley funnel (70 cm), with heat resistant plate. Rinse the beaker five times and filter the rinsings with 100 ml of warm (about 50°) water that has been filtered through GF/B paper. Dry the filter paper with the residue at 105° for 1 h. Transfer to desiccator containing silica gel and leave to cool. Weigh the paper (M 2 ). Calculate the percentage of total insolubles from Total insolubles (%) = [(M 2 - M 1 )/S] x 100
- Test: Galacturonic acid and Degree of amidation
- Weigh 5 g of the sample to the nearest 0.1 mg, and transfer to a suitable beaker. Stir for 10 min with a mixture of 5 ml of hydrochloric acid TS, and 100 ml of 60% ethanol. Transfer to a fritted-glass filter tube (30 to 60 ml capacity) and wash with six 15-ml portions of the HCl-60% ethanol mixture, followed by 60% ethanol until the filtrate is free of chlorides. Finally wash with 20 ml of ethanol, dry for 2.5 h in an oven at 105°, cool and weigh. Transfer exactly one-tenth of the total net weight of the dried sample (representing 0.5 g of the original unwashed sample) to a 250-ml conical flask and moisten the sample with 2 ml of ethanol TS. Add 100 ml of recently boiled and cooled distilled water, stopper and swirl occasionally until a complete solution is formed. Add 5 drops of phenolphthalein TS, titrate with 0.1 mol/l sodium hydroxide and record the results as the initial titre (V 1 ). Add exactly 20 ml of 0.5 mol/l sodium hydroxide TS, stopper, shake vigorously and let stand for 15 min. Add exactly 20 ml of 0.5 mol/l hydrochloric acid and shake until the pink colour disappears. Titrate with 0.1 mol/l sodium hydroxide to a faint pink colour which persists after vigorous shaking; record this value as the saponification titre (V 2 ). Quantitatively transfer the contents of the conical flask into a 500-ml distillation flask fitted with a Kjeldahl trap and a water-cooled condenser, the delivery tube of which extends well beneath the surface of a mixture of 150 ml of carbon dioxide-free water and 20.0 ml of 0.1 mol/L hydrochloric acid in a receiving flask. To the distillation flask add 20 ml of a 1-in-10 sodium hydroxide solution, seal the connections, and then begin heating carefully to avoid excessive foaming. Continue heating until 80-120 ml of distillate has been collected. Add a few drops of methyl red TS to the receiving flask, and titrate the excess acid with 0.1 mol/l sodium hydroxide recording the volume required, in ml, as S. Perform a blank determination on 20.0 ml of 0.1 mol/l hydrochloric acid, and record the volume required, in ml, as B. The amide titre is (B - S). Transfer exactly one-tenth of total net weight of the dried sample (representing 0.5 g of the original unwashed sample) and wet with about 2 ml ethanol in a 50-ml beaker. Dissolve the pectin in 30 ml of 0.1 mol/l sodium hydroxide. Let the solution stand for 1 h with agitation at room temperature. Transfer quantitatively the saponified pectin solution to a 50-ml measuring flask and dilute to the mark with distilled water. Transfer 25 ml of the diluted pectin solution to a distillation apparatus and add 20 ml of Clark's solution, which consists of 100 g of magnesium sulfate heptahydrate and 0.8 ml of concentrated sulphuric acid and distilled water to a total of 180 ml. This apparatus consists of a steam generator connected to a round-bottom flask to which a condenser is attached. Both steam generator and round-bottom flask are equipped with heating mantles. Start the distillation by heating the round-bottom flask containing the sample. Collect the first 15 ml of distillate separately in a measuring cylinder. Then start the steam supply and continue distillation until 150 ml of distillate have been collected in a 200-ml beaker. Add quantitatively the first 15 ml distillate and titrate with 0.05 mol/l sodium hydroxide to pH 8.5 and record volume required, in ml, as A. Perform a blank determination on 25 ml distilled water. Record the required volume, in ml, as A 0 . The acetate ester titre is (A - A 0 ). Calculate degree of amidation (as % of total carboxyl groups) by the formula: B - S 100 x V 1 V 2 (B - S) - (A - A 0 ) Calculate mg of galacturonic acid by the formula: 19.41 x [V 1 + V 2 + (B – S) – (A – A 0 )] The mg of galacturonic acid obtained in this way is the content of one-tenth of the weight of the washed and dried sample. To calculate % galacturonic acid on a moisture- and ash-free basis, multiply the number of mg obtained by 1000/x, x being the weight in mg of the washed and dried sample. NOTE 1: If the pectin is known to be of the nonamidated type, only V1 and V2 need to be determined and (B - S) may be regarded as zero. NOTE 2: For pectins from apple or citrus (A - A 0 ) is usually insignificant in calculating galacturonic acid and degree of amidation. NOTE 3: If desired, calculate degree of esterification (as % of total carboxyl groups) by the formula: V 2 - (A - A 0 ) 100 x V 1 V 2 (B - S) - (A - A 0 ) NOTE 4: If desired, calculate degree of acetate ester (as % of total carboxylic groups from galacturonic acid) by the formula: A - A 0 100 x V 1 V 2 (B - S) - (A - A 0 )
- Test: Residual solvents (Vol. 4)
- Determine residual solvents using headspace gas chromatography (Method I) Internal standard solution: Add 50.0 ml water to a 50 ml vial and seal. Accurately weigh and inject 15 μl of 3-methyl-2-pentanone through the septum and reweigh to within 0.01 mg. Standard solution: Add 50.0 ml water to a 50 ml vial and seal. Accurately weigh and inject 15 μl ethanol and weigh to within 0.01mg. Inject 15 μl isopropanol through the septum and reweigh the vial. Blank solution: Add 5.0 ml of water and pipette 1.0 ml of the internal standard solution into a headspace vial. Seal the vial and mix the contents using a vortex mixer. Calibration solution: Add 4.0 ml of water into the headspace vial. Pipette 1.0 ml each of the internal standard solution and the standard solution. Seal the vial and mix the contents using a vortex mixer. Preparation of sample: Accurately weigh 0.500 + 0.001 g of sample in a small weighing boat. Pipette 5 ml of water and 1 ml internal standard solution into a headspace vial. Add the sample carefully to prevent clumping of sample at the bottom of the vial. S eal the vial and mix the contents using a vortex mixer. Do not shake the sample vial. Follow the procedure described in Vol. 4.

Evidence and how bodies read it
What assessing bodies concluded
Each conclusion is paraphrased in the body's own framing, from the published opinion linked beneath it. Where bodies differ, both stand; this site does not adjudicate between them or add a view of its own.
EFSA 2021
In a follow-up covering infants below 16 weeks, the FAF Panel found that the margin of safety for pectin and amidated pectin (E 440) was below 1 in some scenarios and that maximum permitted levels could produce an internal methanol dose that could cause adverse effects in such infants. It recommended reducing the maximum permitted levels in foods for special medical purposes for infants and young children, and amending specifications for toxic elements.
EFSA 2017
The ANS Panel concluded that there is no safety concern for the use of pectin and amidated pectin (E 440) as food additives for the general population and that no numerical ADI is needed, noting that the available genotoxicity data, while limited, gave no indication of concern.
Common questions
Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.
- What is E 440?
- E 440 is Pectins. Pectin is the gelling agent that sets jam, and is also used in confectionery, fruit preparations and desserts.
- What is Pectins used for in food?
- It is listed as an emulsifier, a thickener and a stabiliser — the role Canada, Codex and the US assign it. This page shows every function each regulator records, with the citation for each.
- Where is Pectins permitted?
- Of the seven regulators this site reads, Australia and New Zealand, Canada, the EU, Great Britain, South Korea, the US and the Codex standard permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
- Is Pectins vegan?
- Yes. Pectins is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
