Buy Food Preservation Activated Carbon

In food preservation, activated charcoal is only used in a secondary role based on its strong adsorption properties. Its primary function is in packaging systems or as a processing aid to eliminate undesirable compounds that cause food to spoil. It adsorbs odours, volatile organic compounds (VOCs), ethylene gas (the ripening hormone for fruits and vegetables), and moisture that are mixed in with the surrounding environment of packaged foods or in the storage facilities. Thus it helps extend shelf life, maintain quality attributes (e.g. freshness, colour) and can prevent off-flavours.
 
That said, activated charcoal is not a food-preserving additive the way antimicrobials are food-preserving additives. There is very strict regulation of its use. It is generally recognized as safe (GRAS) but only for specific indirect applications (e.g. filtering water, oils used in processing; as packaging liners, sachets, or filters in containers). It adsorbs the substances that make the surroundings cleaner, lower in moisture, and devoid of ethylene gas to lessen the degradation. It is considered a conjunctive or non-nutritive additive.

Process and Technolog

1.Ethylene Adsorption in Fruit & Vegetable Storage

Solution Overview

Cold storage units or transportation containers use activated carbon filters or sachets, which adsorb ethylene gas that is a ripening hormone in produce and causes spoilage. Activated carbons from biomass (like from coconut shells or olive stones) have been treated to maximize their adsorption capacity and allow regenerability.

2. Odor and VOC Removal in Storage Environments

Solution Overview

Activated carbon sachets or panels are used in refrigeration units, in warehouses, or packaging to adsorb volatile organic compounds (VOCs), microbial metabolites, and odors (i.e. ammonia, aldehydes) that contribute to the deterioration of food quality.

3. Humidity Control in Dry Food Storage

Solution Overview

Granular activated carbon (e.g., binchotan charcoal) is embedded in storage containers for grains, rice, or dried goods to adsorb excess moisture and inhibit mold growth or insect infestation.
