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…

Major Causes of Postharvest Decline in Fresh Produce

The main causes for postharvest decline in fresh produce are mechanical damage, respiration, transpiration, ethylene, and senescence. The importance of each cause varies across classes of fresh produce, including root vegetables, leafy vegetables, flower vegetables, immature fruit vegetables, and mature fruits. Adequate technology adoption can significantly reduce postharvest decline. Around 40-50% of fruits and vegetables… Continue reading…

Truth About Calibration: Why Factory Settings Aren’t Forever

When you first power on a new instrument, it is easy to assume the factory settings will hold steady for years. In reality, gas analyzer calibration is not a one time event. It is an ongoing process that directly affects data integrity, storage decisions, and ultimately profitability. In postharvest environments where small shifts in oxygen,… Continue reading…

Truth About Multi-Gas Monitors: When Extra Sensors Add Noise

The conversation around multi-gas monitors often centers on one assumption: more sensors equal better data. In controlled atmosphere storage, ripening rooms, and produce research, that sounds reasonable. But in practice, multi-gas monitors can introduce complexity, cross-interference, and calibration drift that compromise accuracy. When extra sensors add noise instead of clarity, the result is slower decisions… Continue reading…

Myth: Data Logging Is Optional—It’s Not if You Want Compliance

In food storage, ripening, and controlled atmosphere management, there is a persistent myth that data logging is optional. Teams often assume that if they can spot check gas levels with a handheld unit, that is enough. It is not. If you care about gas analyzer compliance, continuous and reliable data logging is part of the… Continue reading…

Myth: Postharvest Gas Levels Don’t Change Overnight

Postharvest gas analysis is often treated as a routine checkpoint rather than a continuous priority. A common myth in storage and ripening operations is that gas levels remain stable overnight. Many teams assume that once a room is set and verified at the end of the day, oxygen, carbon dioxide, and ethylene concentrations will hold… Continue reading…

Truth About ‘Zero Calibration’ Sensors: Why Manual Verification Still Matters

Zero calibration sensors are often marketed as a way to simplify gas detection and eliminate routine calibration steps. On paper, the promise is attractive. A sensor that automatically maintains its baseline without manual intervention sounds like a clear operational win. In practice, though, zero calibration sensors do not remove the need for manual verification. For… Continue reading…
