E570 – Fatty acids | food additive uses, source and safety

Quick analysis summary about E570 – Fatty acids food additive

Bottom line about E570

E570 is a group of food-grade fatty acids used mainly for processing and texture functions. It is graded GREEN – SAFE at permitted food-additive levels.

Why this grade for E570

The fatty acids covered by E570 are handled by the body like ordinary dietary fatty acids. EFSA found no safety concern at reported uses and use levels.[1]

Who may want to limit or avoid E570

Most consumers do not need to avoid E570 itself. People avoiding animal-derived ingredients may want to check the source because commercial fatty acids can come from plant or animal fats.

Common uses and where E570 appears

E570 may appear in confectionery, bakery products, powdered foods, chewing gum, coatings and processing aids. It helps with release, lubrication, anti-foaming and texture control.

E570 source or origin

E570 is usually made by splitting and purifying edible fats and oils. The source is variable and may be plant-derived, animal-derived or mixed depending on the manufacturer.

Intake note for E570

EFSA did not set a numerical ADI (Acceptable Daily Intake) because the available evidence and expected exposure did not indicate a need for one. The contribution from E570 to total saturated fatty acid intake was estimated to be small.[1]

Is E570 banned anywhere?

E570 is authorised in the European Union and fatty acids are permitted in the United States for specified food uses under good manufacturing practice. No clear major food-use ban was identified in the reviewed jurisdictions, although allowed uses and purity specifications can differ by country.

Safety grading GREEN – SAFE

E570 is graded GREEN – SAFE because it consists of fatty acids that are normal constituents of food fats and oils, and because food-additive exposure is small compared with everyday dietary fat intake. The main caveat is not acute toxicity, but source transparency, purity specifications and the difference between additive-level exposure and a diet high in saturated fat.[1-3]

Study basis or key toxicological reasoning for E570

EFSA reviewed caprylic, capric, lauric, myristic, palmitic, stearic and oleic acids as E570 and concluded that they are absorbed like free fatty acids from the regular diet, show low acute toxicity and raise no genotoxicity concern. The available subchronic feeding studies were limited and older, but they showed no toxic effects up to 10 percent in the diet, equivalent to about 9000 mg lauric acid/kg body weight per day.[1] JECFA reached a similar metabolic conclusion for related fatty acid salts, and independent nutrition reviews support that fatty acid chain length and structure influence absorption and metabolism rather than suggesting a specific additive-level toxicity signal.[2-4]

Side effects of E570 – Fatty acids food additive

Digestive discomfort: Large amounts of fat-rich foods can cause nausea, fullness or loose stools in some people, but this is not specific to E570.
Source sensitivity: People avoiding animal-derived ingredients, pork-derived materials or certain religiously restricted sources should check with the manufacturer when the source matters.
Purity concern: Food-grade specifications matter because fatty acids can carry small amounts of unsaponifiable material or contaminants if poorly refined.
Nutrition confusion: E570 is not the same issue as eating a high-saturated-fat diet, although some E570 components are saturated fatty acids.
Excessive intake: Very high intake from fat-rich foods is more likely to affect calorie balance and blood lipid patterns than the small additive quantity of E570.

Should You Avoid E570 – Fatty acids food additive?

Most people do not need to avoid E570 when it appears as a food additive. It is made from fatty acids that are already common in ordinary foods, and toxicological reviews do not show a meaningful hazard at permitted levels. The more practical concern is the whole food. If a product is high in saturated fat, sugar or salt, that overall nutrition profile matters more than E570. Vegans, vegetarians and people with religious dietary restrictions may want source confirmation because labels usually do not state whether the fatty acids came from plant or animal oils.

Common uses of E570 – Fatty acids food additive

Confectionery as a glazing, release or texture aid.
Bakery products to help processing and reduce sticking.
Powdered foods where flow, wetting or processing performance needs support.
Chewing gum and coatings as a lubricant or release agent.
Food manufacturing as a defoaming or anti-foaming aid.
Ingredients and premixes where fatty acids help disperse or process other components.

What is E570 – Fatty acids food additive?

E570 is the E-number for a group of free fatty acids used in food technology. The group includes medium-chain and long-chain fatty acids such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid and oleic acid. These substances are not artificial dyes, preservatives or sweeteners. They are lipid-derived ingredients with physical functions in food manufacturing.

Industrially, fatty acids are commonly produced by hydrolysing edible fats and oils, then distilling, fractionating and refining the resulting mixture. Depending on the starting material, E570 can be based on vegetable oils, animal fats or mixed sources. In food, E570 can reduce sticking, help release products from moulds, limit foam, improve processing and support coating or lubrication. Chemically, fatty acids contain a carboxylic acid head and a hydrocarbon chain. The chain length and saturation level influence melting point, texture and how the fatty acid behaves during processing.

Where is E570 – Fatty acids food additive allowed (EU vs US)?

In the European Union, E570 is authorised as a food additive under the fatty acids entry and must meet EU specifications. In the United States, FDA permits food-grade fatty acids such as capric, caprylic, lauric, myristic, oleic, palmitic and stearic acid for use as lubricants, binders and defoaming agents under good manufacturing practice.
