The use of propylene glycol in food products, especially in processed and fried foods, is common due to its ability to act as a solubilizing agent, helping to combine various ingredients that would otherwise separate. Its presence is often associated with a dry, crumbly texture, and it can enhance flavor and preservation. Despite its role in food, propylene glycol is considered a food additive and is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA).
Here are some common food products that may contain propylene glycol:
-
Processed meats: Propylene glycol is used in the processing of some meat products to improve shelf life, texture, and flavor intensity.
-
Baked goods and cakes: It is a common ingredient in fried foods due to its ability to keep baked goods and pastries light and fluffy by absorbing moisture.
-
Packaged snack foods: Cookies, snacks, and candy often contain propylene glycol to provide texture and a crispiness, especially in fried or deep-fried formulations.
-
Soft drinks and soda pop: Propylene glycol may be used as an anti-collapsing agent in the production of carbonated beverages to help keep them aerated and frothy.
-
Salad dressings, condiments, and marinades: These contain propylene glycol to help distribute flavors evenly and to keep the ingredients suspended.
-
Breakfast cereals and oatmeal: Some varieties of breakfast foods may use propylene glycol to bind ingredients and improve texture.
-
Frozen foods and ice pops: Propylene glycol is often used as a preservative to maintain the frozen state of these products.
-
Dairy products, including ice cream and ice milk: Some propylene glycol containing products are used to control ice crystal growth and improve texture.
-
Canned vegetables and fruits: In some cases, propylene glycol may be utilized to control the viscosity of liquids in canned produce.
-
Shredded cheese, cheese whips, and ready-to-eat meals: Propylene glycol might be used as a texture enhancer in these foods by helping to combine and stabilize shredded or chopped cheese.
It is important to note that while propylene glycol is a safe food additive in the amounts typically found in food, individuals with propylene glycol dietary allergies or sensitivities may experience adverse reactions, including skin irritation or rashes upon consuming foods that contain this chemical.
