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.

E 418 Gellan gum
Gellan gum is a high molecular weight polysaccharide gum produced by a pure culture fermentation of a carbohydrate by strains of Pseudomonas elodea, purified by recovery with propan-2-ol or ethanol, dried, and milled. The high molecular weight polysaccharide is principally composed of a tetrasaccharide repeating unit of one rhamnose, one glucuronic acid, and two glucoses, and substituted with acyl (glyceryl and acetyl) groups as the O-glycosidically linked esters. The glucuronic acid is neutralised to a mixed potassium, sodium, calcium, and magnesium salt

INS 418 Gellan Gum
Gellan gum is a high molecular weight polysaccharide gum produced by a pure culture fermentation of a carbohydrate by Pseudomonas elodea , purified by recovery with ethanol or 2-propanol, dried, and milled. The high molecular weight polysaccharide is principally composed of a tetrasaccharide repeating unit of one rhamnose, one glucuronic acid, and two glucose units, and is substituted with acyl (glyceryl and acetyl) groups as the O-glycosidically-linked esters. The glucuronic acid is neutralized to a mixed potassium, sodium, calcium, and magnesium salt. It usually contains a small amount of nitrogen containing compounds resulting from the fermentation procedures.

- Test: Residual solvents
- Standard solutions Transfer 100.0 mg of chromatographic quality ethanol into a 200-ml volumetric flask and 150.0 mg of 2-propanol into a 20-ml volumetric flask, then dilute to volume with water. Pipet each 1 ml of solutions into a 100-ml volumetric flask and dilute to volume with water as standard solution A. Pipet 10 and 5 ml of standard A into two separate 20-ml volumetric flasks and dilute to volume with water as standard solution B and standard solution C. Chromatography conditions Column: 25% diphenyl-75% dimethylpolysiloxane (60 m x 0.25 mm i.d. with 1.4 μ m-film) [Aquatic-2 (GL-Sciences Inc.) or equivalent] Carrier gas: Helium Flow rate: 1.8 ml/min Detector: Flame ionization detector (FID) Temperatures: - Injection port: 250° - Oven: Hold for 5 min at 40°, then 40° to 92° at 4°/min - Detector: 260° The retention times of ethanol and 2-propanol are about 6.5 and 7.5 min, respectively. Samples Weigh accurately 0.10 g of the sample into each of four 20 ml head-space vials. Add a magnetic stirring bar and 10 ml of either water, standard solution A, B or C into each vial and seal. After standing vials overnight at room temperature, stir the solution in the vials for 1 min. Procedure Place the sample vial in the sample tray on head-space gas chromatograph. Heat vials at 60° for 40 min with continuous agitation. Inject 1.0 ml of the head space gas (Syringe temperature: 100°, Transfer temperature: 120°) in the vial into the chromatograph and measure the peak area for ethanol and 2-propanol. Plot the relationship between the added amount against the peak area for ethanol or 2-propanol. Extrapolate the x-intercept for ethanol and 2-propanol (we and wp). Calculate the concentration of ethanol and 2-propanol from; Ethanol (mg/kg) = wE /W 2-Propanol (mg/kg) = wP /W Where W is weight of sample (g).
- Test: Microbiological criteria
- Total plate count Using aseptic technique, disperse 1 g of sample into 99 ml of phosphate buffer and use a Stomacher, shaker or stirrer to fully dissolve. Limit dissolving time to about 10 min and then pipette 1 ml of the solution into separate, duplicate, appropriately marked petri dishes. Pour over the aliquot of sample in each petri dish 12-15 ml of Plate Count Agar previously tempered to 44-46°. Mix well by alternate rotation and back and forth motion of the plates, allow the agar to solidify. Invert the plates and incubate for 48±2 h at 35±1°. After incubation count the growing colonies visible on each plate and record the number of colonies. Take the average of both plates, and multiply by the sample dilution factor, 100. Where no colonies are visible, express the result as less than 100 cfu/g. E. coli Using aseptic technique, disperse 1 g of sample in 99 ml of Lactose broth using either a Stomacher, shaker or stirrer to fully dissolve the sample. Limit the dissolving time to about 15 min and then lightly seal the container and incubate the broth for 18-24 h at 35±1°. Using a sterile pipette, inoculate 1 ml of the incubate into a tube containing 10 ml GN broth. Incubate for 18-24 h and then streak any GN broths showing positive growth or gas production onto duplicate plates of Levine EMB agar. Incubate the plates for 24±2 h at 35±1° and then examine for colonies typical of E. coli i.e. showing strong purple growth with dark centre and a green metallic sheen sometimes spreading onto the agar. Record any typical E. coli colonies as presumptive positive, otherwise negative. Streak any well isolated suspect colonies onto a plate of PCA and incubate for 18-24 h at 35±1°. Perform a Gram stain on any growth to confirm it is Gram negative. If so, disperse any colony growth into a small volume of 0.85% saline and perform chemical tests to confirm the identity of the bacterial growth. This can most conveniently be done by using API 20E or Micro ID strips or equivalent systems. After completion of the tests, identify the organism from the Identification manual of the system used and record the final result. Media GN Broth (Gram Negative Broth) Peptone 20.0 g Dextrose 1.0 g Mannitol 2.0 g Sodium citrate 5.0 g Sodium deoxycholate 0.5 g Potassium phosphate (dibasic) 4.0 g Potassium phosphate (monobasic) 1.5 g Sodium chloride 5.0 g Make up to 1 litre with distilled or de-ionised water, pH 7.0±0.2 at 25°. Salmonella Using aseptic technique, disperse 5 g of sample into 200 ml of sterile lactose broth using either a Stomacher, shaker or stirrer to maximise dissolution over a 15 min period. Loosely seal the container and incubate at 35±1° for 24±2 h. Continue as per method on page 104 in Volume 4 (under “General methods, Salmonella ). Identification can be more conveniently done using API or Micro ID systems or equivalent. Yeasts and moulds Using aseptic technique, disperse 1 g of sample into 99 ml of phosphate buffer and use a Stomacher, shaker or stirrer to fully dissolve. Limit dissolving time to about 10 min and then pipette 1 ml of the solution into separate, duplicate, appropriately marked petri dishes. Pour over the aliquot of sample in each petri dish 15-20 ml of Potato dextrose Agar (either acidified or containing antibiotic) previously tempered to 44-46°. Mix well by alternate rotation and back and forth motion of the plates, and allow the agar to solidify. Invert the plates and incubate for 5 days at 20-25°. After incubation, count the growing colonies visible on each plate using a colony counter and record the number of colonies. Separate the yeasts from the moulds according to their morphology and count them separately. Take the average of both plates and multiply by the sample dilution factor, 100. Where no colonies are visible, express the result as less than 100 cfu/g.

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 2018
The ANS Panel concluded that no numerical ADI is needed for gellan gum (E 418) and that there is no safety concern at the refined exposure assessment for reported uses and use levels. It recommended better-defined specifications, including absence of viable cells of the source microorganism.
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 418?
- E 418 is Gellan gum. Gellan gum is a fermentation-derived gelling agent that works at very low concentrations. It is used to keep cocoa particles suspended in chocolate milk and pulp evenly distributed in some juices.
- What is Gellan gum used for in food?
- It is listed as 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 Gellan gum 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 Gellan gum vegan?
- Yes. Gellan gum is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
