What is Propylene Glycol and is it safe for consumption?
Propylene Glycol (PG) is a synthetic liquid substance that is used as a humectant, solvent, and preservative in a wide range of products, including food, cosmetics, and pharmaceuticals. It is generally recognized as safe (GRAS) for use in food by the US Food and Drug Administration (FDA), but its safety has been a topic of controversy in recent years. Some studies have suggested that PG may be toxic in large quantities, while others have found no adverse effects.
Despite the controversy, PG is commonly used in many food products, including ice cream, cake mixes, and soft drinks. It is also used as a carrier for flavorings and colorings. However, the FDA requires food manufacturers to list PG on the label if it is used as an ingredient. The FDA also sets a maximum allowable limit for PG in food products, which is typically 70% of the total formula. It’s worth noting that the European Food Safety Authority (EFSA) has also evaluated the safety of PG and concluded that it is safe for consumption in the amounts typically used in food products.
Is Propylene Glycol always listed on food labels?
No, Propylene Glycol is not always listed on food labels. While the FDA requires food manufacturers to list PG on the label if it is used as an ingredient, there are some exceptions. For example, if PG is used as a processing aid or as a component of a flavoring or coloring, it may not be listed on the label. Additionally, some food manufacturers may use alternative names for PG, such as 1,2-propanediol or propane-1,2-diol, which may not be immediately recognizable as PG.
In some cases, food manufacturers may also use PG in combination with other ingredients, such as carrageenan or locust bean gum, which can make it difficult to identify PG on the label. Furthermore, some countries may have different labeling requirements for PG, so it’s possible that PG may not be listed on the label of imported food products. To avoid consuming PG, consumers can choose to buy products that are labeled as “PG-free” or “natural,” or they can contact the food manufacturer directly to ask about the ingredients used in their products.
