摘要

Drying methods are essential in the production of nori-like products from Ulva lactuca, because it directly affects both process efficiency and product quality. Therefore, this research aimed to evaluate drying kinetics and physicochemical properties of restructured seaweed sheets subjected to three drying methods, namely conventional tray drying (TD), ultrasound-assisted vacuum drying (UAVD) at varying temperatures (UAVD-T), and UAVD at different vacuum pressures (UAVD-P). Thirteen thin-layer drying models were tested, with Aghbashlo, Midilli–Kucuk, and Modified Page models in order to determine the best fit for predicting moisture removal behavior. This showed that UAVD-T achieved the highest drying rate (DR) and effective moisture diffusivity (Deff) at 70 °C and 20 kPa, while UAVD-P preserved the highest protein and fiber content at 20 kPa. Across treatments, UAVD was used to obtain a lower total color change (ΔE), reduced water activity, and higher retention of antioxidant capacity (IC₅₀: 122–148 ppm) compared to TD. The finding confirmed that UAVD enhanced drying performance and preserved key quality attributes, supporting its potential as a sustainable method for producing seaweed-based nori analogs. This research also provided the first comprehensive kinetics modeling framework for UAVD-treated U. lactuca, used to inform future applications in industrial process optimization and the development of green drying technologies.
