Is Imidazolidinyl Urea Vegetarian?
CautionSometimes. Imidazolidinyl urea is used to "brown" baked goods. It is usually synthetic, but if extracted from animals, it is excreted from urine and other bodily fluids.
Imidazolidinyl Urea and the Vegetarian Diet
Imidazolidinyl urea is primarily a synthetic chemical compound used as a preservative in a wide range of cosmetic products. Occasionally, it is also used in the food industry, particularly to promote browning in baked goods. While it can theoretically be derived from animal sources, it is almost exclusively produced synthetically for commercial purposes. Its use in food is less common and typically limited to processed goods requiring enhanced color or preservation.
