From ice cream to salad dressing, emulsifiers hold processed foods together. Learn which ones to watch for and how to find products without them.
Scan for Hidden EmulsifiersOil and water don't mix — unless you add an emulsifier. That basic chemistry principle explains why emulsifiers have become one of the most widely used categories of food additives in the world. They create stable mixtures out of ingredients that would otherwise separate, giving products a smooth, uniform texture and extending shelf life by weeks or months. You'll find them in ice cream, chocolate, bread, margarine, salad dressing, non-dairy milk, processed cheese, and countless other items.
The most common emulsifiers on food labels include lecithin (often from soy or sunflower), mono- and diglycerides of fatty acids, polysorbate 60 and 80, carboxymethylcellulose (CMC), carrageenan, and sodium stearoyl lactylate. Some of these have been used in food production for decades with little controversy. Others have attracted scientific attention more recently — particularly carrageenan and polysorbate 80, which studies published in Nature and other journals have linked to changes in gut microbiome composition and intestinal inflammation in animal models.
Does this mean you should panic every time you see an emulsifier on a label? No. But it does mean that understanding which emulsifiers are in your food — and how frequently you're consuming them — is a worthwhile exercise. Most people have no idea how many different products in their fridge rely on these additives. Scanning labels is the fastest way to find out.
Point BerryPure at a barcode and the app parses the full ingredient list. Every emulsifier is identified by name and category — so you'll see not just 'E471' but also what it actually is (mono- and diglycerides) and what it does in the product.
BerryPure distinguishes between emulsifiers with minimal research concerns (like sunflower lecithin) and those with more active scientific debate (like carrageenan and polysorbate 80). The purity score weighs these differently so you get a nuanced picture rather than a blanket warning.
For many product categories, emulsifier-free versions exist — you just have to know where to look. BerryPure's swap suggestions surface these alternatives so you can make an informed choice without spending twenty minutes comparing labels by hand.
Almond milk with carrageenan and gellan gum
Almond milk with only almonds, water, and a pinch of salt (brands like Malk or Three Trees)
Carrageenan is added to prevent separation in nut milks. Minimal-ingredient almond milks may separate slightly — just shake the carton. The tradeoff is a cleaner ingredient profile with no gut-irritating thickeners.
Store-bought ice cream with polysorbate 80 and mono-diglycerides
Ice cream made with cream, sugar, egg yolks, and vanilla (brands like Häagen-Dazs or local creameries)
Polysorbate 80 and mono-diglycerides create the airy, smooth texture of industrial ice cream. Traditional ice cream achieves this with egg yolks as a natural emulsifier. Check the label — some premium brands still add guar gum, which is less concerning but worth noting.
Chocolate bars with soy lecithin and PGPR
Bean-to-bar chocolate that uses only cocoa butter for smoothness
PGPR (polyglycerol polyricinoleate) is a synthetic emulsifier that lets manufacturers use less cocoa butter — reducing cost at the expense of quality. Craft chocolate makers rely on longer conching times and cocoa butter alone to achieve a smooth melt.
Sliced bread with DATEM and sodium stearoyl lactylate
Bakery bread or sourdough with flour, water, salt, and yeast
DATEM (diacetyl tartaric acid esters of mono-diglycerides) and SSL are dough conditioners that allow bread to be mass-produced at high speed. Traditional bread-making doesn't need them — it just requires more time for the dough to develop.
Non-dairy coffee creamer with dipotassium phosphate and mono-diglycerides
Oat milk with simple ingredients (oats, water, salt, oil) or real cream
Non-dairy creamers are essentially emulsifier delivery systems — they need multiple stabilizers to mimic the mouthfeel of cream. A clean oat milk or a splash of half-and-half achieves the same thing with far fewer additives.
Everything you need to know about ultra-processed food and sugar detox.
The emulsifiers you'll encounter most frequently on labels are: soy lecithin, sunflower lecithin, mono- and diglycerides of fatty acids (E471), polysorbate 60 and 80, carrageenan, carboxymethylcellulose (CMC), guar gum, xanthan gum, DATEM, sodium stearoyl lactylate (SSL), and PGPR. Lecithin and guar gum are among the most benign; carrageenan and polysorbate 80 are among the most debated.
Research is ongoing. A widely cited 2015 study in Nature found that carboxymethylcellulose and polysorbate 80 altered gut bacteria and promoted intestinal inflammation in mice at concentrations relevant to human consumption. A follow-up human trial published in Gastroenterology in 2022 found that carboxymethylcellulose affected the gut microbiome in healthy volunteers. These findings are concerning but not yet definitive — more human trials are needed.
Lecithin is generally regarded as one of the safest emulsifiers. It's a naturally occurring phospholipid found in egg yolks, soybeans, and sunflower seeds. Soy lecithin may be a concern for people with soy allergies, and some people prefer sunflower lecithin as an alternative. From a processing standpoint, lecithin is far less controversial than synthetic emulsifiers like PGPR or polysorbate 80.
An emulsifier stabilizes mixtures of oil and water so they don't separate. A thickener increases viscosity — making liquids more gel-like or paste-like. Some additives, like xanthan gum and guar gum, function as both. On labels, you'll often see them listed without any distinction. BerryPure categorizes each additive by its primary function so you know exactly what role it plays in the product.
It's extremely difficult if you eat any packaged food. Emulsifiers are in bread, chocolate, plant-based milks, ice cream, sauces, and dressings. A more realistic approach is to minimize exposure by choosing products with fewer and less controversial emulsifiers — favoring lecithin over polysorbate 80, for instance — and cooking from scratch when practical.
The EU uses E-numbers to classify emulsifiers and requires safety evaluations by the European Food Safety Authority (EFSA). Some emulsifiers approved in the U.S. face stricter limits or additional labeling requirements in Europe. For example, the EU has been re-evaluating several emulsifiers in light of new gut health research. However, most common emulsifiers are approved on both sides of the Atlantic.
