Sažetak
Fresh peaches and nectarines are very popular for their high nutritional and therapeutic value. Unfortunately, they are prone to rapid deterioration after harvest, especially if cold chain doesn’t maintain well. The objective of this work is to study the environmental fluctuation and the quality change of fresh peach and nectarine in cold chain. The temperature, relative humidity and CO2 level were real-time monitored by the sensor nodes with wireless sensor network (WSN). Cold chain lasted for 16.8 h and consisted of six segments. The dynamic change of temperature, relative humidity, and CO2 level were real-time monitored and analyzed in details in every of the six stages. The fruit quality index (fruit weight, fruit firmness and soluble solids concentration (SSC)) were detected and analyzed immediately before stages S1 and at the beginning of S6. The results show that fruit softening is the most significant problem even in the short chain without good temperature control ; the WSN node can provide complete and accurate temperature, humidity and gas monitoring information in cold chain, and further improve quality safety and assurance for peach fruit cold chain.
