Simulated Intra-city E-commerce Delivery:Effect of Temperature on the Quality of Fresh Ruditapes philippinarum
The quality of fresh Ruditapes philippinarum is susceptible to deterioration,which is more likely to occur under the relatively rudimentary conditions of intra-city e-commerce delivery.The focus of this study is the effect of temperature and delivery time on the quality of fresh Ruditapes philippinarum during simulated intra-city e-commerce delivery process,and the quality indicators,such as survival rate,total bacterial colony count,water retention capacity,TVB-N content,TBA value,color difference,texture characteristics,moisture distribution,and MRI characteristics,etc,were examined at three delivery temperatures(10 ℃,25 ℃,and 35 ℃).The results showed that the increased of delivery temperature and time significantly reduced the survival rate,and browned of clam flesh,while increased the total bacterial count,TVB-N content,TBA value,cooking loss rate,and juice loss rate.Meanwhile,the proportion of immobile water decreased while the proportion of free water increased,and the red-yellow area and cavities on the MRI pseudo-color image were expanded,resulting in deteriorated texture.It indicated that delivery condition at 10 ℃ and 2 h helps to maintain the quality of fresh Ruditapes philippinarum.This study can provide a reference for the optimization of intra-city delivery conditions for fresh Ruditapes philippinaru.
