Blanching is a critical step in the processing of (). The effects of different blanching methods (boiling water blanching (BWB), ultrasonic-low temperature blanching (ULTB), and high-temperature steam (HTS)) on the quality and moisture migration characteristics of were investigated. The results showed that the blanched by ULTB (70 °C, 2 min, 40 kHz, 300 W) had the best quality, including a brighter appearance, superior texture, and good sensory features, with a polysaccharide content of 3.90 ± 0.02%. The moisture migration characteristics of after blanching exhibited four peaks, displayed strong and weak chemically bound water, immobilized water, and free water, whereas ULTB had a weak effect on the freedom of water in . The study will provide the foundation for the factory processing of .
热烫是（）加工过程中的关键步骤。研究了不同热烫方法（沸水热烫（BWB）、超声低温热烫（ULTB）和高温蒸汽（HTS））对（）品质和水分迁移特性的影响。结果表明，经ULTB（70℃，2分钟，40kHz，300W）热烫的（）品质最佳，外观更亮，质地优良，感官特性良好，多糖含量为3.90±0.02%。热烫后（）的水分迁移特性呈现四个峰，表现出强结合水、弱结合水、束缚水和自由水的强弱，而ULTB对（）中水分的自由度影响较小。该研究将为（）的工厂化加工提供依据。
