Mechanisms and Process Optimization for Traditional Freeze-Air-Drying of Pollock (Mentaiko)
Year: 2025
Type: article
Abstract: Global climate change poses significant challenges to the production of dried Pollock—a traditional delicacy of China's Korean & Manchu ethnic minority. The traditional sun-drying process relies on specific temperature, humidity, and ventilation conditions; however, changes in these environmental factors threaten this valuable cultural heritage. This study systematically analyzes the physical and biochemical mechanisms involved in the drying process, focusing on the effects of temperature, humidity, illumination, and microbial activity. Based on our findings, we propose an artificial environmental scheme to partially replace the increasingly unsuitable natural conditions, thereby ensuring the quality of dried Pollock and the preservation of traditional techniques. By optimizing the traditional process, this work offers innovative solutions to mitigate the impact of climate change on the culinary culture of China's Korean & Manchu ethnic minority.
