This course is part of Module II: Technology and Practice on Grain Postharvest Loss Reduction within the webinar series on postharvest loss reduction organized by the WFP Centre of Excellence for Rural Transformation (WFP China COE). The series was held from August 27th to September 26th, 2024, with support from the Academy of China’s National Food and Strategic Reserves Administration (NAFRA).

The overall objective of this webinar series is to share China’s extensive experience, technologies, and practices in reducing postharvest loss. Across two modules—Module I: Experience on Grain Postharvest Management and Module II: Technology and Practice on Grain Postharvest Loss Reduction—a total of 16 Chinese presenters introduced China’s approaches to postharvest management and demonstrated key technologies applied by aggregators at various stages of the postharvest process.

Within this framework, the present course focuses on the storage of paddy and wheat, tracing the evolution from traditional to modern storage practices. It covers China’s national standards for grain storage quality, the classification and indices used to assess storage quality, and the methods for measuring and controlling key quality parameters. The course also examines green storage technologies, pest control strategies, and recent lipidomic research related to grain quality deterioration.
