摘要

以红宝石李为原料,采用常压、真空、超声波和微波3种渗糖加工方式,研究不同渗糖工艺下红宝石李果脯的色泽、质构特性、总糖含量、复水性、水分构成、滋味以及果脯品质的感官变化。结果表明:采用真空渗糖技术能够显著提高产品的亮度,微波渗糖得到的产品色泽较差;超声波渗糖的产品复水率、硬度和韧性显著偏高(P<0.05),总糖含量最高;微波和超声波渗糖制备果脯中结合水的相对含量显著偏高(P<0.05)。电子舌滋味测定结合感官评价超声波渗糖制备的果脯滋味最佳。

Abstract

With ruby plum as experimental raw materials, the preserved fruits were processed by various sugar infiltration technologies such as atmospheric pressure, vacuum, ultrasonic wave and microwave, in order to study how different sugar infiltration methods affect the color, texture characteristics, total sugar content, rehydration, water composition, taste and sensory evaluation of preserved ruby plum.The results demonstrated that vacuum sugar infiltration technology could improve the color brightness of the product significantly, while the color obtained by microwave sugar infiltration was poor.Preserved fruits which applied ultrasonic wave sugar technology had observable higher rehydration rate, hardness and toughness (P<0.05), and the gross sugar content was the highest.The relative content of bound water in the preserved fruit prepared by microwave and ultrasonic wave sugar infiltration technologies was remarkably higher (P<0.05).Moreover, the results of electronic tongue measurement and sensory evaluation showed that the preserved fruit processed by ultrasonic wave sugar infiltration has the best taste.
