This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Propylene glycol (PG) is a synthetic liquid substance that absorbs water and is commonly used in food products. It serves various functions, including acting as a solvent, preservative, and moisture-retaining agent. Here’s what you need to know about propylene glycol in foods:

Uses in Food

  • Solvent and Carrier: Propylene glycol is often used as a solvent for food colors and flavors, helping to evenly distribute these ingredients throughout the product1 2.
  • Preservative: It helps extend the shelf life of foods by inhibiting the growth of mold and bacteria1.
  • Moisture Retention: PG is used to maintain moisture in food products, which is particularly beneficial in baked goods and processed foods1.

Safety and Regulations

  • Generally Recognized as Safe (GRAS): The U.S. Food and Drug Administration (FDA) classifies propylene glycol as “generally recognized as safe” for use in food1.
  • Acceptable Daily Intake: Regulatory bodies have established acceptable daily intake levels to ensure consumer safety, although these levels can vary by country1.

Health Considerations

  • Metabolic Effects: In studies involving dairy cows, propylene glycol has been shown to influence metabolic status and milk production, suggesting it can affect energy metabolism1 2.
  • No Significant Adverse Effects: Research indicates that propylene glycol does not significantly alter body condition or metabolic markers in dairy cows, implying a level of safety in its use2.

Conclusion

Propylene glycol is a versatile ingredient used in the food industry for its solvent, preservative, and moisture-retaining properties. It is considered safe for consumption within regulated limits, with no significant adverse health effects reported in studies. Its role in food products is primarily functional, enhancing the quality and shelf life of various items.
