摘要

为了提高银耳热泵干燥（HPD）的效率和质量，本研究采用超声预处理方法，评价不同超声强度[0.00（对照组，CK）， 0.20, 0.34, 0.54和0.74 W/g]对银耳干燥行为和产品属性的影响。结果表明，超声预处理能显著加速干燥过程。0.34 W/g预处理组干燥时间最短（855 min），比CK组（945 min）缩短9.52% (p <0.05)，复水率比CK组（1138.00±1.41%）提高7.25%(1220.50±24.75%)（p <0.05）。多糖含量在0.54 W/g时达到最大值24.80±0.25%，比CK组（21.67±0.26%）提高了14.44% （p <0.05）。色度保持稳定。微观结构和水分迁移分析表明，超声预处理促进了水蛭多孔疏松微观结构的形成，使水分在组织内的空间分布均匀，增强了水分在HPD过程中的扩散。可溶性蛋白含量则有所降低。综合评价，推荐超声强度为0.34 ~ 0.54 W/g为最佳预处理范围。本研究为优化山楂干燥工艺，促进山楂产业化应用提供理论指导和实践数据支持。

Effect of ultrasound pretreatment on the drying characteristics and quality of Tremella fuciformis under heat pump drying

To enhance the heat pump drying (HPD) efficiency and quality of Tremella fuciformis (T. fuciformis), this study employed ultrasound pretreatment and evaluated its effects on drying behavior and product attributes at various ultrasound intensities [0.00 (the control group, CK), 0.20, 0.34, 0.54, and 0.74 W/g]. The results showed that ultrasound pretreatment significantly accelerated the drying process. The 0.34 W/g pretreatment group achieved the shortest drying time (855 min), which was 9.52% shorter than the CK group (945 min) (p <0.05), and improved the rehydration rate by 7.25% (1220.50 ± 24.75%) compared to the CK group (1138.00 ± 1.41%) (p <0.05). The polysaccharide content reached a maximum value of 24.80 ± 0.25 % at 0.54 W/g, which was 14.44% higher than that of the CK group (21.67 ± 0.26%) (p <0.05). The chromatism remained stable. The microstructure and moisture migration analysis showed that ultrasound pretreatment promotes the formation of porous and loose microstructures in T. fuciformis, which homogenizes the spatial distribution of moisture inside the tissue and enhances moisture diffusion during the HPD process. However, the soluble protein content showed a reduction. Based on a comprehensive evaluation, ultrasound intensities of 0.34 ∼ 0.54 W/g are recommended as the optimal pretreatment range. This study provides theoretical guidance and practical data support for optimizing the drying process and promoting industrial application of T. fuciformis.
