The effect of “1-MCP treatment + cold storage agent + insulation package” to simulated transportation of the fresh blueberry

In order to investigate the“1-methylcyclopropene ( 1-MCP) treatment, cold storage agent and insulation package”model to the effect of fresh blueberry by simulated transportation, the fresh blueberry ( Powderblue) was taken as the research object.And the process was carried out as follows: fumigated by the 1-MCP ( 1.0 μL/L, ( 26 ± 2) ℃) for 4 h, then loaded in a foam box after twelve-hour pre-cooling while being added in some cold storage agent, after that, vibrate simulation was carried out in 35 ℃ of external environment condition at the speed of 100 km/h, after 24 h or 48 h, the box was opened and the product was placed into a Micro-porous Films. Finally the shelf experiment was carried out under 4 ℃ of outer condition for196 h, and each indicator was examined every 48 h. The results showed that the simulated transportation period placed in the cold storage agent under the condition of the same weight, on the final stage of shelf experiment, the decay rate of 1-MCP treatment group in simulated transportation for 24 h ( MP24) was 18.99%, 14.03% and 14.11%, lower than that of the control group in simulated transportation for 48 h ( CK48) , control group simulated transportation for 24 h ( CK24) , and 1-MCP treatment group in simulated transportation for 48 h ( MP48) , respectively, while the firmness of MP24 was 14.20%, 9.93% and 4.67% higher than that of CK48, MP48 and CK24, respectively.Likewise, that could also keep the lowest activities of pectinase, and maintain the content of anthocyanins, total phenol, V_c, GSH.So, it was a kind of low cost, high efficiency of fresh blueberry logistics model which was the “1-MCP treatment, cold storage agent and insulation package”and short-term transportation.
