Production process Introduction
Source factory, high quality, and low price.
Active Clay for Food is a food-grade activated clay with high adsorption capacity, used for decolorizing and purifying edible oils, vegetable oils, and food ingredients.
Advantages
Strong decolorization ability: After acid activation, it forms a larger specific surface area and microporous structure, which can quickly adsorb chlorophyll, oxidized pigments, and colloids.
Improved oil stability: Strong adsorption capacity can remove impurities such as metal ions and oxidation precursors.
Good filtration performance: Uniform particles and stable filter layer structure can maintain a good flow rate and reduce filtration pressure drop.
Minimal impact on nutrients: Chemically stable, it does not react with the effective components in the oil, reducing the loss of vitamins and active substances.
