Propylene Glycol: A Deeper Look at its Role in Food

Understanding Propylene Glycol

Propylene glycol (PG) is a synthetic alcohol that finds widespread use in the food industry as an additive. Also known as 1,2-propanediol, PG's food-grade form is commonly employed as a solvent. It contributes to food processing, enhancing texture, flavor, appearance, and shelf life.

Approved for Safe Consumption

The United States Food and Drug Administration (FDA) has approved the use of propylene glycol in food at specific concentrations, deeming it safe for consumption. It can constitute up to 97% of a product's contents.

Benefits in Food Applications

Propylene glycol offers various advantages as a food additive. It aids in the dissolving of flavors and colors, improving their distribution throughout the food. Additionally, it helps maintain moisture, prevents spoilage, and extends shelf life. PG's thickening and stabilizing properties enhance the texture and appearance of a wide range of food products.
