Decolourisation and purification in sugar, syrup, edible oil and beverage processing, where colour bodies and off-flavours have to be removed.
Wood-based and food-grade powder carbons are the usual starting point, since mesoporosity drives the removal of larger colour molecules.

Food-Grade Coconut Shell Granular Activated Carbon for Odor Removal
Food-grade coconut shell granular activated carbon for odor removal in household and industrial applications. Coconut shell gives a hard, microporous carbon suited to retaining small odor molecules and many volatile organic compounds. The granular 900–1600 µm range suits cartridge fill for household units and packed beds in industrial vessels where low pressure drop matters. The series is specified with iodine adsorption at 900 mg/g or more, methylene blue at 135 mg/g or more, CTC at 40 % or more, and BET surface area of 950–1200 m²/g. Ash is specified at 5 % or less, heavy metals at 10 ppm or less and hardness at 95 % or more, supporting food-related and potable water duties and a stable bed. Values shown are series references; batch values, applicable documents, packaging and moisture protection are confirmed before an order. Buyers are invited to share the object being treated, flow or concentration, target specification, particle size and purchase quantity for a selection review.

Faq
Explore faq details to support your evaluation.
Can food, beverage and refining be mixed with another carbon in one bed?
Yes, but when loading in layers keep the particle sizes close to avoid channelling, and record the test data for each layer.
What is the minimum order quantity?
One tonne for normal orders; samples of 1-5 kg can be shipped with freight paid by the customer.
What lead time should we expect?
Around 15 days for regular grades, and 3-5 days for stock items.
