This study uses material flow analysis (MFA) to assess food waste in China from 2010-2019 across five stages (production, post-harvest handling, processing, distribution, consumption) for seven food categories. Wheat had the highest waste (38% of total), while milk had the least (4%). Scenario hypotheses showed a 5% waste reduction in each stage could reduce soybean imports by 7%. The findings provide data for food waste intervention and food security strategies.
