Abstract For industrialized processes, microwave techniques for quality control and pasteurization methods may be required. For this reason the precise knowledge of the dielectric characteristics of foods are of prime importance. In this paper, we present the dielectric properties of pulque, a Mexican traditional drink. Three different pulque flavors (natural, strawberry and coconut/pineapple) are reported from 100 MHz to 25 GHz using an open-ended-coaxial probe and a vector network analyzer. This characterization was carried out for temperatures ranging from 20 to 70° C in steps of 10° C.

pulque 在 0.1 至 25 GHz 不同温度下的介电特性

摘要 对于工业化过程，可能需要用于质量控制和巴氏杀菌方法的微波技术。因此，准确了解食物的介电特性至关重要。在本文中，我们介绍了墨西哥传统饮料 pulque 的介电特性。使用开放式同轴探头和矢量网络分析仪报告了从 100 MHz 到 25 GHz 的三种不同的 pulque 风味（天然、草莓和椰子/菠萝）。该表征是在 20 至 70°C 的温度范围内以 10°C 的步长进行的。
