What it is
BHA (Butylated Hydroxyanisole) and Propyl Gallate are synthetic antioxidants. BHA is made from petroleum products, while Propyl Gallate is an ester formed from propyl alcohol and gallic acid, which is found naturally in plants.
Why it's used
These ingredients are added to foods to prevent fats and oils from spoiling (turning rancid) due to oxidation. They are commonly found in products with high fat content, such as sausages, hot dogs, processed meats, and some snack foods, to extend their shelf life.
Health notes
Both BHA and Propyl Gallate are approved by the FDA as direct food additives. JECFA has evaluated both BHA and Propyl Gallate and set acceptable daily intakes for each. The International Agency for Research on Cancer (IARC) classifies BHA as possibly carcinogenic to humans (Group 2B), based on studies in animals, though the relevance to human health at typical intake levels is a subject of ongoing discussion. Propyl Gallate is generally considered safe at levels typically consumed in food.
