What is Propylene Glycol (PG)?
Propylene glycol chemical is a synthetic food additive that belongs to the same chemical group as alcohol. It is a colorless, odorless, slightly syrupy liquid that is a bit thicker than water. It has practically no taste. Additionally, it can dissolve some substances better than water and is also good at retaining moisture. This makes it very useful as a food additive, so it can be found in a wide variety of processed foods and drinks.
Where and how is it used?
PG is a commonly used additive that aids in food processing and improves the texture, flavor, appearance, and shelf life of food. Propylene glycol chemical is commonly found in many packaged foods, including drink mixes, dressings, dried soups, cake mixes, soft drinks, popcorn, food coloring, fast food, bread, and dairy products.
In food, propylene glycol has many uses:
- Anti-caking agent: Prevents food components from sticking together and forming clumps, such as in dried soups or grated cheese.
- Antioxidant: Extends the shelf life of food by protecting it from oxygen-induced deterioration.
- Carrier: Dissolves other food additives or nutrients for processing, like colors, flavors, or antioxidants.
- Dough strengthener: Modifies starches and gluten in dough to make it more stable.
- Emulsifier: Prevents separation of food ingredients, such as oil and vinegar in salad dressing.
- Moisture preserver: Helps food maintain a stable moisture level and prevents it from drying out, e.g., marshmallows, coconut flakes, and nuts.
- Processing aid: Enhances the appeal or usability of food, for example, making a liquid clearer.
- Stabilizer and thickener: Holds food components together or thickens them during and after processing.
- Texturizer: Changes the appearance or mouthfeel of food.

Is propylene glycol in food dangerous?
The FDA has categorized propylene glycol as "generally recognized as safe" (GRAS), which means that it's safe for use in food (9). The European Union (EU) has also approved propylene glycol as a food additive.
In the US, it can be used as a direct and indirect food additive. In Europe, it is only allowed to be used in food as a solvent for colors, emulsifiers, antioxidants and enzymes.
