不同干燥方式对黄桃果干品质的影响

Effects of Different Drying Methods on The Quality of Dried Yellow Peach Slices

  • 摘要: 本研究旨在探究不同干燥方式对黄桃果干品质的影响。以黄桃为研究对象,分别采用真空冷冻干燥(FD)及真空冷冻干燥与微波真空干燥(MVD)、热风干燥(HAD)联合干燥方法加工制备黄桃果干,并研究几种干燥方式对黄桃果干质构、微观结构和营养成分等的影响。结果表明:与FD相比,联合干燥可以有效缩短干燥时间,采用真空冷冻干燥—微波真空干燥技术(FM)得到的黄桃果干感官评价总分为91.60,色差值为18.97,同时质构特性和微观结构与FD组差异较小;FM组黄桃果干的营养成分保留显著高于其余联合干燥组(P<0.05),其总多糖、总酚、总黄酮、抗坏血酸含量分别为161.16、15.84、34.02、1.07 mg/g。因此,使用FM技术可以保证品质的同时有效缩短干燥时间。该研究结果可为黄桃果干干燥技术提升提供参考。

     

    Abstract: The aim of this study was to investigate the effects of different drying methods on the quality of dried yellow peach slices. Yellow peach slices were used as the research object, and vacuum freeze-drying (FD) and FD combined with microwave vacuum drying (MVD) and hot air drying (HAD) were used to dry yellow peach slices. The effects of different drying methods on the texture, microstructure, and nutritional composition of yellow peach slices were studied. The results indicated that compared with FD, combined drying methods could effectively shorten the drying time, the total sensory evaluation score and color difference of dried yellow peach slices obtained by vacuum freeze-drying microwave vacuum drying (FM) method were 91.60 and 18.97, respectively, which had little difference in texture characteristics and microstructure compared to the FD group. The nutrient content of FM dried yellow peach slices was significantly higher than that of the other combined drying methods (P<0.05), with the contents of total polysaccharides, total phenolics, total flavonoids, and ascorbic acid were 161.16, 15.84, 34.02, and 1.07 mg/g, respectively. Therefore, FM technology could produce high-quality dried yellow peach slices while shortening the drying time. The research results could provide reference for improving the drying and processing technology of yellow peach slices.
