Pasteurization
Increased shelf life reduces wastage costs, but initial equipment can be expensive.
High Pressure Processing (HPP)
Equipment is costly, but the method extends shelf life without preservatives, appealing to health-conscious consumers.
Irradiation
Initial investment in equipment and regulatory compliance is high, but extends shelf life and reduces health risks.
Smoking
Smoke houses and wood costs must be considered, while product gains flavor, longevity, and can demand premium prices.
Freeze-drying
High energy costs for freezing and vacuum, but products have high value due to long shelf life and retained quality.
Ultraviolet (UV) Treatment
Moderate equipment costs for effective sterilization, but operational costs can be offset by longer shelf life of products.
Extrusion
High-capacity machinery increases throughput with potentially high profit, but initial setup and maintenance costs are substantial.
Microwave Processing
Quick processing time lowers labor costs but requires significant energy use and specialized equipment.
Canning
Metal cans and processing increases packaging costs, but allows for longer storage and wider distribution.
Sous-vide
Requires special equipment and packaging, but provides high-quality, consistent results and reduced labor.
Cold Storage
Ongoing energy costs are a factor but can preserve quality and extend market timing for fresh products.
Vacuum Packaging
Equipment and material costs are high, but it results in longer shelf life and less spoilage.
Membrane Separation
High cost for membrane technology, but efficient for concentrating and purifying products, leading to better product quality.
Pulsed Electric Fields (PEF)
Innovative technology with high initial costs, but offers minimal thermal damage and high-quality products.
Modified Atmosphere Packaging (MAP)
Requires specialized packaging materials and gases, but increases shelf life and product appeal.
Drying/Dehydration
Energy costs for drying are significant, yet results in lightweight products with decreased transportation costs.
Filtration
Filter systems can be expensive, yet they improve product purity and can reduce long-term operational costs.
Fortification
Adding nutrients increases product value, but incurs costs for quality control and ingredient sourcing.
Fermentation
Low-cost processing that adds value and uniqueness, yet requires precise control and monitoring.
Enzymatic Browning Inhibition
Costs for anti-browning agents and treatments can be offset by the perceived increase in freshness and shelf life of produce.
