Polysorbate is a term that often appears in ingredient lists on food packaging, but many consumers may not fully understand what it means or how it affects the products they consume. In this comprehensive article, we will explore what polysorbate is, its functions, its origins, potential health implications, and its presence in our everyday foods.
What is Polysorbate?
Polysorbate is a type of emulsifier used in food products that helps to blend ingredients that typically don’t mix well, such as oil and water. The term “polysorbate” refers to a group of compounds derived from sorbitol and fatty acids. Often found in various processed foods, polysorbate helps maintain a consistent texture and enhances the overall quality of food products.
The most common forms of polysorbate include polysorbate 20 (Tween 20), polysorbate 80 (Tween 80), and others that vary in their molecular structure and applications. These compounds are widely used in the food industry, but they also have uses in pharmaceuticals, cosmetics, and other industrial applications.
How Is Polysorbate Made?
Polysorbates are synthesized through a chemical process that involves the esterification of sorbitol with fatty acids. This process typically uses a sorbitan (a sugar alcohol derived from sorbitol) and a variety of fatty acid sources. The resulting compound is hydrophilic, enabling it to attract both water and oils, thus combining them into a stable mixture.
The manufacturing process can vary based on the specific type of polysorbate being produced, but the end goal is always the same: to create a product that effectively stabilizes emulsions and enhances their compatibility.
Functions of Polysorbate in Food
Polysorbate serves several significant functions in food products. Understanding these functions can help consumers appreciate why polysorbate is included in many of their favorite items.
Emulsification
One of the primary functions of polysorbate is its ability to act as an emulsifier. Emulsifiers are substances that promote the mixing of liquids that typically don’t blend, such as water and oils. For instance, in salad dressings, polysorbate helps to keep the oil and vinegar combined, preventing separation and ensuring a smooth and consistent product.
Texture Improvement
Polysorbate contributes to the mouthfeel and texture of food products. By optimizing the way ingredients interact, it helps achieve a creamy, appealing texture in items like ice cream and sauces. This improvement in texture not only enhances the eating experience but also makes food appear more visually appealing.
Preservation
Another benefit of polysorbate is its role in food preservation. By stabilizing emulsions, it helps extend the shelf life of products by preventing separation and spoilage. This function is critical in processed foods where long shelf life is a desirable quality.

Regulations and Safety of Polysorbate
In many countries, including the United States, polysorbates are considered safe for consumption. The FDA classifies them as “Generally Recognized As Safe” (GRAS), which means they are permissible as food additives when used appropriately.
European Regulations
In Europe, polysorbates are also approved for use in food products under strict regulatory guidelines set forth by the European Food Safety Authority (EFSA). The safety assessments conducted by EFSA ensure that polysorbates are used within established limits that protect consumer health.
How to Identify Polysorbate in Food Products
To identify polysorbate in food products, consumers can refer to ingredient labels, where it will usually appear as polysorbate 20, polysorbate 60, or polysorbate 80. Labels often use a specific numerical designation to indicate which type of polysorbate is included in the product.
Label Reading Tips
When examining food labels, it’s beneficial to:
- Look for terms such as “polysorbate” followed by a number (such as 20, 60, or 80).
- Familiarize yourself with various emulsifiers and stabilizers that may appear alongside polysorbates.
By being informed and vigilant about ingredient labels, consumers can make educated food choices.
The Future of Polysorbate in Food Production
With an increasing focus on health and wellness, there’s a growing trend towards natural ingredients and clean-label products. As consumers advocate for transparency in food production, some manufacturers are reformulating their products to exclude certain emulsifiers, including polysorbates.
