E471 / Thickeners, stabilisers & emulsifiers
Monoglycerides and diglycerides of fatty acids
Safety in brief
Safe
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.
- Watch for
- No allergen or sensitivity is recorded for this ingredient here. Check the whole product label; this is not an allergen-free guarantee.
- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
Monoglycerides and diglycerides are common emulsifiers made by combining glycerol with fatty acids, used to blend water and oil-based ingredients in margarine, bread, ice cream, and baked goods. They improve texture, extend softness, and prevent separation of ingredients. The fatty acids used can be sourced from either plant oils or animal fat, so strict vegetarians, vegans, and those following religious diets may not be able to confirm the source from labeling alone. They are considered safe and are among the most widely used food emulsifiers.

Research & body effects
Health notes from our ingredient record
- Source (plant or animal fat) is frequently unlisted, which matters for vegans, vegetarians, and religious dietary observance.
- Some derivatives may be produced using partially hydrogenated oils in certain markets, a minor source of trans fat if not fully hydrogenated or interesterified.
- Generally recognized as safe at typical food use levels.

- Food additive emulsifiers and cancer risk — Multiple Authors, BMC Medicine (2024). Large-scale epidemiological study examining associations between food additive emulsifiers (including E471, E472a, E472b) and cancer risk. The study suggests potential deleterious effects of emulsifiers on the intestinal microbiota and metabolome, leading to chronic inflammation. However, the study emphasizes the need for further research to establish causal relationships and notes that current evidence does not warrant immediate regulatory changes.[caution]
- Food additive emulsifiers and risk of cardiovascular disease in the NutriNet-Santé cohort: prospective cohort study — Sellem, L., Srour, B., Gueraud, F., et al., BMJ (2023). Prospective cohort study examining associations between food additive emulsifiers (including E471, E472a, E472b) and cardiovascular disease risk. The study found some associations between higher emulsifier intake and increased cardiovascular disease risk, but emphasized that these findings require replication in other populations and that mechanistic studies are needed to understand potential causal pathways.[caution]
- Re‐evaluation of mono‐ and di‐glycerides of fatty acids (E 471) as food additives — EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS), EFSA Journal (2017). The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re-evaluating the safety of mono‐ and di‐glycerides of fatty acids (E 471) when used as a food additive. The Panel considered that hydrolysis of mono‐ and di‐glycerides of fatty acids by lipases in the gastrointestinal tract would occur, resulting in the release of glycerol and fatty acids. Based on the available data, the Panel concluded that there is no safety concern.[safe]

Country rules
Country checks for E471
Permission depends on the market, type of food, amount and conditions. A scientific opinion or an E-number alone does not establish a legal use. These checks are separate from the stored EatMatrix rating.

| European Union | Regulation (EC) 1333/2008, Annex II Part B, version , contains the exact code E471: Mono-and diglycerides of fatty acids. Listing alone does not allow every food use.
