When you glance at the ingredients list on your favorite packaged food, you might come across the term “E470.” What exactly is this additive, and why is it used in so many products? In this article, we’ll dive into the science behind E470, its uses, safety, and much more. Let’s explore this common food additive in detail.
What is E470 in Food?
E470 refers to a group of food additives known as fatty acid salts. These include mono- and diglycerides of fatty acids, which are commonly used as emulsifiers and stabilizers in food production. Emulsifiers like E470 play a crucial role in ensuring that ingredients that normally don’t mix well—such as oil and water—stay blended together.
For example, in products like margarine or ice cream, E470 helps create a smooth, consistent texture. Without it, these foods might separate or become grainy. E470 is derived from natural sources, such as plant oils or animal fats, and is widely used in the food industry due to its effectiveness and versatility.
How is E470 Made?
E470 is produced through a process called esterification, where fatty acids (from sources like soybean oil or palm oil) are combined with glycerol. This reaction creates mono- and diglycerides, which are the primary components of E470.
The raw materials used in this process are carefully selected to ensure quality and safety. For instance, plant-based oils are often preferred for vegan or vegetarian products. Once synthesized, E470 is purified and tested to meet strict food safety standards before being added to various food products.
How E470 Works
E470 works by reducing the surface tension between two immiscible substances, such as oil and water. Its molecules have a unique structure: one end is hydrophilic (water-loving), and the other is hydrophobic (oil-loving).
When added to a mixture, E470 molecules position themselves at the interface between oil and water. The hydrophilic end faces the water, while the hydrophobic end faces the oil. This arrangement creates a stable emulsion, preventing the ingredients from separating. For example, in mayonnaise, E470 ensures that the oil and egg yolks stay blended, giving the product its creamy texture.
What are Different Types of E470
E470 is divided into two main categories:
- E470a: Mono- and diglycerides of fatty acids.
- E470b: Salts of fatty acids, such as sodium, potassium, or calcium salts.
These variations are used depending on the specific needs of the food product. For instance, E470a is often used in baked goods to improve texture, while E470b is preferred in processed meats for its stabilizing properties.
Common Uses of E470 in Everyday Foods
Baked Goods
In baked goods like bread, cakes, and pastries, E470 plays a crucial role in enhancing texture and shelf life.
- Bread:E470 improves dough strength, resulting in a softer crumb and increased volume. It also helps retain moisture, keeping bread fresh for longer. Without E470, bread might become dry and stale quickly.
- Cakes and Pastries:E470 ensures a light, fluffy texture by stabilizing the mixture of fats and liquids. It also prevents the separation of ingredients during baking, leading to a more consistent product.
For example, in commercial bread production, E470 is often added to dough at a concentration of 0.5% to achieve these benefits.
Dairy Products
E470 is widely used in dairy products to improve texture and stability.
- Ice Cream: E470 helps create a smooth, creamy texture by preventing the formation of large ice crystals. It also stabilizes the mixture of milk, cream, and sugar, ensuring the ice cream doesn’t melt too quickly after serving.
- Yogurt and Cheese Spreads: In these products, E470 prevents the separation of water and solids, maintaining a consistent texture and appearance.
For instance, in ice cream, E470 works alongside other emulsifiers like lecithin (E322) to achieve the desired consistency.
Processed Meats
In processed meats like sausages, burgers, and deli meats, E470 ensures a uniform texture and prevents fat separation.
- Sausages: E470 stabilizes the emulsion of meat, fat, and water, giving sausages their characteristic firmness and juiciness. It also helps distribute fat evenly throughout the product.
- Low-Fat Meat Products: In reduced-fat versions of processed meats, E470 compensates for the lack of fat by improving texture and mouthfeel.
For example, in sausage production, E470 is often used in combination with other stabilizers to achieve the desired consistency.
Margarine and Spreads
E470 is essential in margarine and spreads, where it keeps the oil and water phases blended.
- Margarine: E470 ensures a smooth, spreadable texture by stabilizing the emulsion of oil and water. It also prevents the margarine from splattering when heated.
- Low-Fat Spreads: In reduced-fat spreads, E470 helps mimic the texture of full-fat products, making them more appealing to consumers.
For instance, in margarine production, E470 is often used alongside other emulsifiers like lecithin (E322) to achieve the desired consistency.
Confectionery
In confectionery products like chocolate and candies, E470 improves texture and stability.
- Chocolate: E470 ensures a smooth, glossy finish by stabilizing the mixture of cocoa butter, sugar, and milk solids. It also prevents the formation of a dull, white layer (known as “bloom”) on the surface of chocolate.
- Chewing Gum: E470 helps maintain the soft, chewy texture of gum by stabilizing the mixture of gum base, sweeteners, and flavorings.
For example, in chocolate production, E470 is often used at a concentration of 0.5% to achieve these benefits.
Ready-to-Eat Meals
In ready-to-eat meals like soups, sauces, and dressings, E470 prevents the separation of ingredients and improves texture.
- Soups and Sauces: E470 stabilizes the mixture of water, oil, and solids, ensuring a smooth, consistent texture. It also helps maintain the product’s appearance during storage.
- Salad Dressings: E470 keeps the oil and vinegar blended, preventing separation and ensuring a uniform consistency.
For instance, in creamy salad dressings, E470 is often used alongside other emulsifiers to achieve the desired texture.
Is E470 Safe? Potential Side Effects Explained
E470 is generally recognized as safe by regulatory bodies like the FDA and EFSA. However, some individuals may experience mild side effects, such as digestive discomfort, if consumed in large quantities.
It’s important to note that E470 is derived from natural sources and is widely used in the food industry. For those with specific dietary restrictions, such as vegans, it’s worth checking the source of E470, as it can be derived from animal fats.
How to Correctly Use E470
When using E470 in food production, manufacturers must adhere to strict guidelines regarding dosage and application. For consumers, it’s essential to read food labels carefully to identify products containing E470.
For example, if you’re looking to avoid E470 due to dietary preferences, check the ingredients list for terms like “mono- and diglycerides of fatty acids” or “E470.”
Why is E470 Used in Food? Benefits Explained
E470 offers several benefits in food production:
- Improved Texture: It creates smooth, consistent textures in products like ice cream and margarine.
- Extended Shelf Life: By stabilizing emulsions, E470 helps prevent spoilage and maintain freshness.
- Cost-Effectiveness: It’s an affordable and efficient way to enhance food quality.
For instance, in baked goods, E470 ensures that bread stays soft and fresh for longer, reducing food waste.
