Description
Palm Oil-Specific Activated Clay | Core Advantages
1.Superior carotenoid removal
Highly targeted adsorption of carotenoids—the main pigment in palm oil—delivers excellent decolorization results and brightens refined oil appearance.
2.Dual purification capacity
Simultaneously adsorbs free fatty acids (FFAs) and off-flavors, improving palm oil’s oxidation stability and taste quality in one step.
3.High process adaptability
Performs stably in both batch and continuous palm oil refining systems, and works well with subsequent fractionation and deodorization processes.
4.Low oil retention rate
Optimized porous structure minimizes oil entrainment during filtration, maximizing refined palm oil yield and reducing production losses.
5.Cost-efficient application
Requires only 0.8%–2.2% dosage relative to oil weight; regenerable for repeated use to cut long-term operational costs.
Character
White or off-white powder.
Main Effects
Removes phospholipids, soap, and trace metal ions from oils and fats.
Removes aflatoxin and odor-causing substances from oils and fats.
This product offers good adsorption capacity, excellent decolorization performance, low oil retention, fast filtration speed, and low dosage.
Product Uses
Used in the edible oil refining industry for the decolorization and purification of animal and vegetable oils.
Technical Indicators
Reference Standard: GB25571-2011
| Item | Indicator |
| Specific Surface Area, m²/g | ≥ 130 |
| Free Acid, calculated as H₂SO₄, % | ≤ 0.30 |
| Moisture, W/% | ≤ 12.0 |
| Particle Size, -200 Mesh, % | ≥ 90 |
| Lead, Pb, mg/kg | ≤ 40 |
| Arsenic, As, mg/kg | ≤ 3 |
Suggested Use
Heat the oil to 100–120°C. Slowly add 3%–7% activated bleaching clay and stir for 20–30 minutes. Allow the mixture to settle, then remove the clay by filter press.
Notes
Store in a dry and ventilated place away from direct sunlight.
Protect the product from mechanical impact and rain.
The product begins to lose crystal water above 300°C, which may change its structure and affect the decolorization effect.
The product surface easily absorbs moisture, so moisture-proof storage is required.
Packing Specification
Packed with an inner plastic film layer and an outer plastic woven bag, or packed according to customer requirements.
Standard packing weight: 25 ± 0.25 kg per bag, or customized according to customer requirements.
Period of Validity
