International Numbering System (INS) for Food Additives: 470a
Food additives Europe numbers: E470a
Sodium, potassium, and calcium salts of fatty acids, also known collectively as E 470a, are a group of commonly used food additives. They aren't single ingredients but a combination of fatty acid salts derived from various sources. Here's a breakdown of their key characteristics:
Origin and Function:
- Made from fatty acids: These additives are formed when common fatty acids like stearic, oleic, palmitic, and myristic acid react with sodium, potassium, or calcium [1]. These fatty acids come from animal or vegetable fats.
- Emulsifiers and anticaking agents: Their primary role in food is to act as emulsifiers and anticaking agents [2].
- Emulsifiers: They help stabilize mixtures of ingredients that wouldn't normally blend well together, like oil and water, creating a smooth and consistent texture in things like baked goods, ice cream, and salad dressings.
- Anticaking agents: They prevent ingredients from clumping together, ensuring a free-flowing consistency in powdered foods like dry mixes or cheeses.
Safety:
- Generally recognized as safe (GRAS): Regulatory bodies like the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) consider these salts safe for their intended uses when consumed within set limits [3, 4].
Applications:
- Wide variety of processed foods: Due to their functionality, you might encounter sodium, potassium, and calcium salts of fatty acids in a wide range of processed foods, including:
- Baked goods (cakes, breads, cookies)
- Desserts (ice cream, puddings)
- Dairy products (cheeses, yogurt)
- Processed meats
- Fats and oils
- Confectionery (candy)
- Sauces and dressings
- Beverages (may be used in some low-fat drinks)
Overall:
Sodium, potassium, and calcium salts of fatty acids are versatile food additives that help with texture and stability in many processed foods. While generally safe, if you're concerned about food additives in general, you can always consult a healthcare professional or registered dietitian for more personalized advice.
