Description

Butter-Specific Activated Clay | Core Advantages

1.High-selectivity adsorption

Targets only pigments, off-flavors and trace impurities in butter without affecting its natural texture and nutritional components.

2.Low addition ratio

Requires only 0.3%–0.8% dosage relative to butter weight, minimizing production costs while ensuring refining effects.

3.Food-grade safety

Complies with strict food safety standards, non-toxic and residue-free, suitable for edible butter processing.

4.Mild operation condition

Works efficiently at low temperature (45–55℃), avoiding butter oxidation or quality deterioration during refining.

5.Extended shelf life

Removes substances that cause butter spoilage, effectively prolonging the product's storage period and stability.

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.
