                                Over half of all ultra-processed foods in the UK contain emulsifiers, demonstrating their prevalence in modern food production. These essential chemical compounds play a vital role in keeping liquids that typically resist mixing—like oil and water—uniformly blended, creating the smooth textures we expect in everything from mayonnaise to lotions.
