Buy Food Preservation Activated Carbon
업계 과제
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.

프로세스 및 기술
1.Ethylene Adsorption in Fruit & Vegetable Storage
솔루션 개요
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.
주요 이점
- 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
솔루션 개요
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.
주요 이점
- 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
솔루션 개요
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.
주요 이점
- 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).
- Non-Toxic Operation: Safe for direct contact with dry foods without leaching harmful substances.
4. Packaging Material Integration
솔루션 개요
Active packaging incorporates activated carbon layers or inserts (e.g., sachets, films) within MA (Modified Atmosphere) packaging systems to scavenge ethylene, oxygen, or odors during transit and retail display.
주요 이점
- Synergy with MA Technology: Enhances gas composition stability by complementing oxygen/CO₂ modifiers, prolonging shelf life.
- Space-Efficient Design: Thin films or micro-sachets minimize bulk while maximizing gas contact surface area.
- Broad Compatibility: Adaptable to flexible/rigid packaging formats for fruits, meats, and dairy products.
5. Food Processing Byproduct Purification
솔루션 개요
Activated carbon columns or batch treatments are used to decolorize or deodorize liquid food extracts (e.g., fruit juices, peptide hydrolysates) by adsorbing pigments, bitter compounds, or residual aromatics.
주요 이점
- Selective Refinement: Removes unwanted components (e.g., aromatic amino acids in peptide solutions) while retaining functional nutrients.
- Process Flexibility: Adjustable pore structure and surface chemistry allow customization for specific solute adsorption.
- High Purity Output: Produces clear, neutral-tasting ingredients suitable for functional foods.
6. Advanced Preservation Systems with Catalytic Components
솔루션 개요
Hybrid systems combine activated carbon beds (e.g., bamboo charcoal-based composites) with UV irradiation or catalytic metals (e.g., TiO₂) to decompose adsorbed VOCs via oxidation, enhancing regeneration and efficacy.
주요 이점
- Destructive Adsorption: Converts harmful gases (e.g., ethylene, aldehydes) into CO₂ and water via catalytic breakdown, preventing saturation.
- Energy Efficiency: UV-triggered reactions operate at ambient temperatures, reducing energy use versus thermal regeneration.
- Scalable Configuration: Modular designs enable deployment in small storage units to industrial cold rooms.
