Fresh fruits and vegetables are highly perishable commodities, and maintaining their quality from harvest to consumption remains one of the biggest challenges in the global food supply chain. Recent academic study (Gouda and Duarte, 2024) shows that nearly 40% of fresh produce is lost during post-harvest handling, storage, and transportation, largely due to inadequate environmental control. Among the key parameters influencing freshness, carbon dioxide (CO2) plays a crucial role in preserving post-harvest quality. Appropriate CO2 levels help inhibit respiration, reducing the consumption of nutrients and slowing the ripening process to better maintain flavor and texture. At the same time, CO2 can suppress ethylene production and action by interfering with its biosynthesis and receptor binding, effectively delaying softening and senescence. Moreover, high CO2 concentrations inhibit the growth of molds and bacteria that cause decay, significantly reducing the incidence of post-harvest diseases. The effects make precise CO2 regulation a critical factor in controlled atmosphere storage (CAS) and modified atmosphere packaging (MAP) systems.In both dimensions, CO2 plays a key role in balancing respiration and microbial control, effectively minimizing post-harvest losses.
In response to the industry challenges, Cubic, a leading manufacturer of gas sensors and analyzers, has developed the SRH series industrial grade CO2 sensor based on advanced non-dispersive infrared (NDIR) technology. The SRH series provides reliable real-time CO2 measurement for fruit and vegetable preservation, greenhouse management, and cold-chain applications, helping extend freshness, reduce post-harvest losses, and enhance supply chain resilience.
Featuring the advantages of wide and flexible measurement range from 0–5000 ppm to 0–20% Vol, customizable up to 60% Vol, Cubic SRH series delivers high accuracy, rapid response, and long-term reliability. Equipped with matrix calibration technology, SRH series maintain high-accuracy performance across the full operating temperature range, while the built-in humidity compensation algorithm ensures stable operation under 0–95% RH conditions. Designed with diffusion sampling, it enables direct ambient gas measurement without external pumps or flow systems, ensuring easy installation and low maintenance. The features make the SRH Series an ideal solution for fruit and vegetable preservation and cold-chain transportation applications, where precise CO2 measurement supports enhanced supply chain resilience.
As industry demand for high-quality preserved fresh produce continues to rise, advanced environmental monitoring has become more critical than ever. Through innovation in gas sensing technology, Cubic empowers producers and cold-chain operators with accurate and reliable CO2 monitoring sensors. The Industrial Grade CO2 Sensor not only supports effective preservation and storage management but also contributes to building a more efficient and resilient agricultural supply chain.
