Have you ever spotted the word "emulsifier" on a food package? You may have wondered what that meant and why it was on the label. Emulsifiers are specific substances that are used to improve the characteristics of many everyday foods. In this article, we'll cover what emulsifiers are, why we use them, and how to approach eating foods with emulsifiers. The better you know emulsifiers, the better choices you will make about foods you love.
To learn a bit more about emulsifiers, it’s useful to understand the processes involved in making some foods. Oil and water are present in many foods, but do you realise that oil and water does not have a good relationship with each other when alone? They have a tendency to separate, which can make food less appealing in looks and taste. And here’s where emulsifiers come into play: there additives are put into these type of foods to maintain the oil and water blended. This mixing is crucial as it ensures a uniform consistency for the food and acts to bind together all its components to prevent them from separating.
It is like a salad dressing made with oil and vinegar. Without an emulsifier, the oil would sit on top of the vinegar and form a layer. But when an emulsifier is introduced, mustard for example, it allows the oil and vinegar to come together and bond, resulting a creamy and delicious dressing. Which is why emulsifiers are so useful in cooking and food production.
The purpose of emulsifiers in most cases is to enhance the likeness of the products. They help make the food look smooth and gives it a nice feel on the palate when you consume it. Emulsifiers can also keep some foods from spoiling as quickly on store shelves or make them easier to manufacture in factories. For example, some foods could separate into layers or clump together without emulsifiers. This would make them unappealing and thus not very fun to eat, and so emulsifiers are essential for food manufacturers.
Now that you know what emulsifiers do, you may be wondering if they are safe for us to eat. The positive side is that emulsifiers work well in small amounts. The emulsifiers that we use in our food are tested and have passed in front of organizations like the FDA (Food and Drug Administration). These tests help to ensure that the emulsifiers we eat are safe for us.
But it’s worth noting that they aren’t likely to be great for you in excess. Certain types of emulsifiers might negatively influence gut health and contribute to inflammation throughout the body, which some studies suggest happens if your diet contains a lot of them. Although more research is needed for understanding these possible risks, it’s wise to eat foods with emulsifiers in moderation. That means savoring them, but not going overboard.
You use different emulsifiers for different food types. For example, lecithins are often used in chocolate and baked goods to keep them smooth and homogenous. Mono- and diglycerides, which are found in many processed foods, are used to ensure sufficient texture. Polysorbates are commonly used as an ingredient in ice cream and other frozen goods to prevent ice crystals from forming to keep the dessert smooth and easy to eat.
