What Is Postharvest Physiology and Why Does It Matter for Fresh Produce Quality?

The crucial postharvest physiological processes that lead to deterioration in the quality of fresh produce include respiration, transpiration, ethylene production, and enzymatic activity. Temperature, air gas composition, relative humidity, and handling are common factors that can be controlled to slow these physiological processes. Maintaining and controlling the environment is essential to preserving quality and shelf… Continue reading…

What’s the Difference Between F-900 and F-950 Gas Analyzers?

F-950 Three Gas Analyzer

When comparing the F-900 and F-950 gas analyzers, the simplest way to separate them is this: the F-900 is built first around highly sensitive ethylene measurement, while the F-950 is built for fast, portable measurement of ethylene, CO2, and O2 together. Both instruments come from Felix Instruments and both serve produce, storage, ripening, research, and… Continue reading…

Fruit Logistica 2026 Tech Talk: How to Verify Ethylene Control in Cold Storage

At Fruit Logistica 2025, we shared practical guidance on how to verify ethylene control in cold storage and retail environments. While many facilities implement abatement systems, validation is often limited to spot checks or periodic manual testing. In this session, we demonstrated why single-point measurements can miss critical exposure patterns and how continuous, real-time monitoring… Continue reading…

WEBINAR: How to Verify Ethylene Control in Your Storage Environment

Validating ethylene control and removal systems has always been a critical, but often time-consuming, part of product development. Traditional validation methods can slow teams down with manual sampling, offline analysis, and delayed feedback. These delays make it harder to confirm system performance and hold back innovation in technologies designed to manage ethylene effectively. Felix Instruments… Continue reading…

What Is an Ethylene Monitoring System and Why Is It Critical for Fresh Produce?

Ethylene monitoring systems can have fixed or portable sensors. Other components of the monitoring systems could be data logging, data transmission, connectivity, remote access, and a control event scheduler. The sensors used to detect ethylene must be sensitive, selective, stable, rapid, and have the required lower limit and detection range. Ethylene monitoring in the postharvest… Continue reading…

What Is Ethylene Gas and Why Is It Shortening Your Fruit’s Shelf Life?

Ethylene is a natural phytohormone produced by plants and climacteric fruits, but also exists in the supply chain through anthropogenic sources. Ethylene accelerates unplanned ripening processes, causes decay, and increases susceptibility to physiological problems and pathogens. The effects of ethylene depend on fruit maturity stage, species, cultivars, the concentration and exposure duration of the gas,… 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 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…

Postharvest Technology for Non-Climacteric Fruits: Best Practices and Benefits

Non-climacteric fruits have a short storage life as they must be harvested ripe. Several steps, like precooling and treatments, prepare the non-climacteric fruits for quality retention. Modified atmospheric packaging, controlled atmospheric storage, and different packaging systems maintain suitable environmental conditions during storing, transportation, and marketing to extend shelf life. Ripening is the last stage of… Continue reading…
