Carvão ativado para conservação de alimentos
Buy Food Preservation Activated Carbon
Desafios do sector
Regulatory Fragmentation
- Inconsistencies among regulations around the globe complicate the ability to remain compliant. Some regions permit activated charcoal as a food colorant, while some allow it to be used in food indirectly (e.g., as a filter in packaging) but not allow in food otherwise. These differences in regulation make it difficult to market and formulate products internationally!
Non-selective Adsorption
- Its indiscriminate adsorption behavior removes both target contaminants (ethylene, odors) and beneficial compounds (nutrients, flavor molecules), potentially diminishing nutritional value or altering sensory profiles in preserved foods.
Process Integration Constraints
- Optimizing contact time and loading ratios without compromising food texture/solubility requires tailored solutions for different products. Post-application residue removal also adds operational complexity.
Quality Standardization Gaps
- Inconsistent definitions of "food-grade" specifications across suppliers lead to variable purity levels and performance reliability, hindering quality assurance and large-scale adoption.
Material Limitations
- Conventional activated carbon faces capacity saturation during long-term storage, while regeneration isn't feasible for direct food contact applications, limiting extended effectiveness.

Processo e tecnologia
1.Ethylene Adsorption in Fruit & Vegetable Storage
Visão geral da solução
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.
Principais vantagens
- Extended Freshness: Significantly delays over-ripening and decay by reducing ambient ethylene concentrations.
- Sustainable Sourcing: Utilizes agricultural waste (e.g., coconut shells, olive stones) as raw materials, promoting circular economy principles.
- Reusability: Retains adsorption efficiency after regeneration cycles, reducing waste generation.
2. Odor and VOC Removal in Storage Environments
Visão geral da solução
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.
Principais vantagens
- Multicomponent Adsorption: Simultaneously targets diverse spoilage-inducing gases (e.g., formaldehyde, ethanol) through non-selective physical adsorption.
- Preserved Sensory Quality: Prevents flavor contamination and maintains original taste/aroma by eliminating volatile off-flavors.
- Chemical-Free Preservation: Avoids synthetic additives, ensuring no residue on food surfaces.
3. Humidity Control in Dry Food Storage
Visão geral da solução
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.
Principais vantagens
- Moisture Regulation: Maintains optimal dryness levels to prevent caking, clumping, or microbial proliferation.
- Dual Functionality: Combines humidity control with adsorption of musty odors or lipid oxidation volatiles (e.g., in nuts or cereals).
