Propylene Glycol in the Food Industry
The importance of propylene glycol in the food industry runs the gamut from improving texture to elongating shelf life. Bell Chem, food ingredient supplier for small and large industries alike, carries propylene glycol for these functions and many others. Propylene glycol is similar to alcohol in its chemical form. Because it is both colorless and odorless, it does not detract from food flavor or appearance. It does, however, enhance several aspects of food. Since it is a glycol, its viscosity is higher than that of water.
Propylene glycol dissolves a number of substances not permeated by water and retains moisture when added as an ingredient. Other names for propylene glycol include methyl ethyl glycol, trimethyl glycol, and 1,2-propanediol. Propylene glycol has many uses in food production. Here are some of those uses.
Anti-Separating
Adherence of individual food crumbs is not pleasant in mixes and cheese, where it can lead to bacterial growth. Adding propylene glycol separates food particles, allowing it to work as an anti-caking agent. In the same way, propylene glycol acts as an emulsifier. Like oil and water, many other ingredients tend to separate over time. Propylene glycol blends liquids to maintain consistency, such as in milk or other dairy products.
Beer production
Brewers rely on propylene glycol, not directly in beer, but within the chiller system to maintain the perfect brewing temperature. At 35% glycol to 65% water, propylene glycol is able to keep equipment running effectively and efficiently, improving performance and preventing breakdowns.
Carrier
Many processed foods contain added color, flavor, or nutritional additives. To ensure the proper distribution of these additives, propylene glycol dissolves other chemicals. The act of processing foods may alter their appearance, taste, or texture. Propylene glycol can clarify liquids, stabilize taste, and ensure the creamy texture of foods.
Preservative
Adding propylene glycol to marshmallows and nuts stabilizes moisture content in a process known as moisture preservation. Oxygen degenerates many items, including foods. Propylene glycol protects foods against these oxidizing effects.
Stabilization and Thickening Agent
Propylene glycol modifies gluten and starches within bread and pastry dough, keeping the dough from breaking down under certain conditions. This stabilization is used in various other foods as well to lengthen shelf life.
