Abstract：
This study aimed to produce dried tarhana using a refractance window drying (RWD) system. The drying process was also carried out under vacuum; the current study is the first in the literature. Using different heating mediums, the maximum temperature can be adjusted to a level above that used in RWD studies. Considering results, process time savings in RWD were over 85% and 75% compared to control groups (oven and hot air dryer), respectively. Tarhana samples dried in RWD were also faster (50%) under vacuum conditions than atmospheric ones. The highest preservation of total phenolic content (TPC) and total antioxidant activity (TAA) was for samples dried by RWD at 110°C under atmospheric conditions. Techno-physical properties were better than the control group. The rheological behavior of tarhana soups was similar to pseudoplastic flow behavior and well defined by the Power law and Herschel-Bulkey models. In conclusion, RWD can be a promising technique for tarhana production.
摘要：
本研究旨在使用折射窗干燥（RWD）系统生产干燥的tarhana。干燥过程也在真空下进行；目前的研究是文献中的第一个。使用不同的加热介质，最高温度可以调整到高于RWD研究中使用的水平。考虑到结果，与对照组(烘箱和热风干燥机)相比，RWD的工艺时间节省超过85%和75%，分别。在RWD中干燥的Tarhana样品在真空条件下也比在大气条件下更快（50％）。在大气条件下通过RWD在110°C干燥的样品中，总酚含量（TPC）和总抗氧化活性（TAA）的最高保存率。技术物理性能优于对照组。tarhana汤的流变行为类似于假塑性流动行为，并由幂律和Herschel-Bulkey模型明确定义。总之,RWD可以是tarhana生产的有前途的技术。
