Postharvest Research on Citrus Off-Gassing Using F-900 Portable Analyzer
Postharvest off-gassing analysis plays a central role in understanding citrus fruit quality, shelf life, and market readiness. In citrus supply chains, small changes in internal gas composition can signal the onset of ripening, senescence, or stress long before visual symptoms appear. Postharvest off-gassing research allows scientists and quality managers to measure these changes directly and… Continue reading…
F-940 for Monitoring Shipping Containers in Long-Haul Fruit Logistics
In long-haul fruit logistics, the F-940 gas analyzer has become a practical tool for teams that need visibility into atmosphere conditions inside shipping containers. When fruit is on the water for weeks or moving across continents by rail, small shifts in oxygen, carbon dioxide, or ethylene can quietly undo months of careful postharvest work. The… Continue reading…
How Processors Use the F-900 for Catalytic Generator Verification
Processors rely on controlled ethylene delivery to manage ripening, degreening, and conditioning programs. When catalytic generators are part of that system, verification matters. The focus for this discussion is on F-900 catalytic generator verification, because accurate ethylene measurement is the only practical way to confirm generator output in real operating conditions. The F-900 gives processors… Continue reading…
Fixed vs Portable Ethylene Monitoring Compared
Ethylene monitoring is central to maintaining fruit quality through storage, transport, and ripening. Even trace levels of ethylene, measured in parts per billion, can alter respiration rates, accelerate ripening, or shorten shelf life. Because ethylene’s impact varies across commodities and handling stages, the way it’s monitored determines how effectively operations preserve product quality and reduce… Continue reading…
What Causes Postharvest Senescence in Fresh Produce
Senescence is one of the top two postharvest processes that cause food loss of fresh produce by curtailing shelf life. Ethylene production, programmed cell death, and cellular energy supply are significant processes associated with senescence in postharvest fresh produce. The mechanisms by which the three processes cause senescence are not entirely understood. Premature senescence and… Continue reading…
How to Improve Fresh Produce Supply Chain Risk Management for Better Food Safety
Supply chain risk management for fresh produce can include macro-level, external, and internal risks. Macro and external risk factors are outside a business’ control and can affect more than one location in the supply chain. Internal risks that cover a business’s operations, processes, and control measures can be managed using controlled atmosphere facilities and monitoring… Continue reading…
How Do the Effects of Ethylene on Flower Quality Impact Floriculture?
Ethylene is one of the main factors affecting flower and ornamental plant quality and longevity in the entire floriculture supply chain. Ethylene inhibits growth, branching, flower bud abortion, and leaf and flower abscission, reducing the quality and longevity of floriculture products. Floriculturists can increase ROI by monitoring and reducing ethylene levels in greenhouses, storage, distribution,… Continue reading…
How Does Controlled Atmosphere Storage Extend Fruit Shelf-Life?
Controlled atmosphere temperature and relative humidity are critical for ripening and storage. The three gases that need to be measured and controlled are ethylene, oxygen, and carbon dioxide. Several conditions, including gas composition, are reversed during the ripening and storage stages of the supply chain. Each postharvest stage of fresh produce requires specific conditions to… Continue reading…
How Degreening of Citrus Fruits Enhances Appearance and Quality
Artificial degreening changes only citrus peel color and does not affect other quality parameters. Several citrus factors, like maturity at harvest and cultivar-specific ethylene sensitivity, will influence degreening success. Postharvest degreening is the standard procedure and requires careful consideration of cultivars to determine atmosphere conditions, ethylene concentrations, and exposure duration to achieve the desired results.… Continue reading…
How the Fruit Ripening Process Affects Freshness and Quality
Respiratory rate, ethylene sensitivity, and production are the main criteria for differentiating ripening patterns. Respiratory peaks that trigger ethylene production start the ripening process in climacteric fruits. Ethylene sensitivity, production, and respiration hike are minimal or absent in non-climacteric fruits. Several fruits show varying degrees of ethylene sensitivity and production and defy neat classification in… Continue reading…
