摘要
利用Hot Disk测定了9种不同种类果蔬在不同低温条件下的导热系数,分析不同可溶性固形物(SSC)含量、含水率(MC)以及不同温度条件对果蔬导热系数的影响。研究发现,在不同温度条件下果蔬的导热系数呈现先下降后上升的趋势;SSC含量越高,导热系数越小,而MC含量越高,导热系数越大。通过研究不同影响因素对果蔬导热系数的影响,可以优化果蔬保鲜过程中的热管理,为成熟果蔬的储存和运输提供理论支撑。
Hot Disk was used to measure the thermal conductivity of 9 kinds of fruits and vegetables under different lowtemperature conditions,and the influences of different soluble solid content(SSC),moisture conten(MC),and different temperature conditions on the thermal conductivity of fruits and vegetables were analyzed.The results showed that the thermal conductivity of fruits and vegetables decreased first and then increased under different temperature conditions.The higher the SSC content,the lower the thermal conductivity,while the higher the MC,the higher the thermal conductivity.By studying the influence of different factors on the thermal conductivity of fruits and vegetables,the thermal management in the process of fruit and vegetable preservation can be optimized and the theoretical support can be provided for the storage and transportation of mature fruits and vegetables.
