    Optimization of Bleaching Process - American Oil Chemists

    Bleaching clay base minerals. Bentonite minerals have limited sorptive properties in the natural state and require chemical treatment by acids to create the surface area and porosity needed for bleaching vegetable oils. Bleaching clays of this nature are commonly referred to as “acid” or “acid-activated” clays.

    The purpose of Bleaching is to remove the color pigments contained inside Vegetable Oils. The neutralized oil is heated at additional temperature through thermic boilers to ultimately raise the temperature of oil upto 120 C to 130 C. The oil is then treated with Bleaching Clays that adsorb the color pigments.

    Bleaching Clay Industry Trends & Opportunities

    Crude oil refining includes degumming, neutralization, bleaching, deodorization, and further refining. Bleaching clay is widely used in the edible oil and fat industry in the decolorizing and refining process. Crude oil is bleached with natural or acid-activated clay minerals to absorb coloring components and to decompose hydro-peroxides.
