Tonsil bleaching earth, also known as activated bleaching clay or activated bleaching earth, is a type of natural clay material that has been specially processed to exhibit highly adsorptive properties. It is commonly used in various industries, particularly in the edible oil and fats industry, for the purpose of bleaching or purifying oils and fats. The term "tonsil" in tonsil bleaching earth refers to the original method of production, which involved using a type of clay called "montmorillonite," named after the Montmorillon region in France. However, modern tonsil bleaching earth may not necessarily contain montmorillonite and can be derived from other clay minerals as well. Tonsil bleaching earth works through a process called adsorption, where it attracts and binds impurities such as pigments, trace metals, free fatty acids, and other contaminants present in oils and fats. These impurities are adsorbed onto the surface of the clay particles, resulting in the purification of the oil or fat. The term "bleaching" in tonsil bleaching earth does not refer to the traditional meaning of removing color, but rather to the removal of undesirable substances that can affect the quality, stability, and appearance of oils and fats. The bleaching process helps to improve the taste, odor, and shelf life of the final product. In summary, tonsil bleaching earth is a specially processed clay material used in industries, primarily the edible oil and fats industry, for the purpose of adsorbing and removing impurities to enhance the quality and stability of oils and fats
