Abstract

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.

脉冲在0.1 ~ 25 GHz不同温度下的介电特性

对于工业化过程，可能需要微波技术进行质量控制和巴氏灭菌方法。因此，准确了解食物的介电特性是至关重要的。本文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，在100 MHz至25 GHz范围内报告了三种不同的风味(天然，草莓和椰子/菠萝)。该表征在温度范围为20至70°C的情况下进行，步骤为10°C。
