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

May 6, 2026 at 4:46 pm | Updated May 6, 2026 at 4:48 pm | 12 min read

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…

Can I Build My Own NIR Model, or Should I Use Felix’s built in models?

An NIR model is only as useful as the data behind it. That is the main point to keep in mind when deciding whether to build your own calibration or use Felix Instruments’ built-in models. In fresh produce, a good NIR model has to deal with cultivar variation, growing region, harvest timing, dry matter range,… Continue reading…

F-950 Three Gas Analyzer

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

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…

3 Mistakes Technicians Make When Using Gas Analyzers

Gas analyzer accuracy plays a central role in postharvest handling, storage management, and quality control. Whether you are monitoring ethylene levels in ripening rooms or checking oxygen and carbon dioxide in controlled atmosphere storage, even small errors can lead to measurable losses. Despite experience in the field, many technicians still make avoidable mistakes that impact… Continue reading…

6 Ways to Extend Instrument Life in Harsh Environments

Working in challenging conditions is part of the job for many industries, especially in agriculture, postharvest handling, and food science. Whether you are dealing with dust, moisture, temperature swings, or rough handling, protecting your equipment becomes essential. Extending instrument life in harsh environments is not just about saving money. It is about maintaining data accuracy,… Continue reading…

Signs Your Gas Sensor Needs Replacement

If you rely on a handheld analyzer for postharvest work, packaging checks, storage rooms, or ripening control, gas sensor replacement is not something to push off until the instrument completely fails. In practice, sensor problems usually show up gradually. Readings get less stable, calibration gets harder to hold, response times slow down, and the numbers… Continue reading…

7 Best Practices for Collecting NIR Data in the Field

Good field NIR data collection starts long before the first scan. In orchards, vineyards, and packing operations, the difference between useful data and noisy data usually comes down to sampling discipline, repeatable technique, and the right instrument setup. That is why field teams using handheld NIR tools need a process that matches the chemistry of… Continue reading…
