Table 3 Comparison summary of intelligent systems in fruit packaging container
Technology | Purpose | Advantages | Disadvantages |
|---|---|---|---|
Electrochemical Ethylene Sensor | Determine the quality of fruit produce Determine the rate of respiration and ripening in fruits by detecting ethylene concentrations released by the fruit | Ethylene sensitive Can be used in individual and bulk packaging Less expensive than NDIR | Susceptible to chemical interference (can be internally mitigated) More costly than indicators |
Capacitive Humidity Sensor | Determine the package environment's quality Determine the relative humidity of the package | Accurate and can be used in bulk packaging | Individual packaging is expensive and impractical |
RFID | Identify and convey package details Package data should be sent to an exterior processing unit | Scalable, simple to read and real time monitoring system | Active tags can be costly External infrastructure is required |
Freshness Indicators | Determine the quality of the packaging environment and the fruit produce Detect the passage of various factor threshold limits (temperature, gas composition disruption) | Scalable, simple to read | Neither quantifies data nor used as sensors |
