Key Points

The aim is to study the mineral composition of raw and acid-activated clays and their effectiveness in clarifying soybean oils.
Characterization of mineralogy using X-ray diffraction and scanning electron microscopy.
Synthesis of porous materials from raw clays using acid activation techniques.
Testing the efficiency of clarified soybean oils through filtration experiments.
Acid treatment improved the specific surface area of clays, enhancing their filtration capability.
Porous materials demonstrated a significant reduction in oil turbidity, suggesting effective clarification.
Chemically altered clays achieved optimal performance at lower dosages compared to raw clays.

Investigates the effectiveness of acid-activated clays for clarifying soybean oils, suggesting potential applications in food technology.
