Ayushi Bleaching
Earth is the most important agent for Bleaching and Decolourising de-gummed and Alkali Refined oils by adsorption. In the process of bleaching Ayushi Bleaching Earth is used alone with activated carbon to remove colour, gums, resins and other impurities present in the oily adsorption due to their High Surface Activities, while having no effect on the composition of the oil so treated.
