As the first academic monograph systematically studying regional food culture in China, A Study on Fuling Zhacai Culture adopts a cultural anthropology perspective to provide a comprehensive analysis of the cultural practices across the entire Zhacai (pickled mustard tuber) industry chain, constructing a trinity analytical framework of "production-circulation-consumption." Through mutual verification of field investigations and literature analysis, it examines core dimensions such as raw material cultivation, processing techniques, technological empowerment, brand construction, and dietary heritage, revealing the inherent logic behind the formation of regional food culture. The study innovatively proposes a "double-helix cultural gene" theoretical model, which organically integrates the traditional artisan spirit of "Integrity to the Utmost Virtue and Striving for Continuous Improvement" with the modern industrial culture paradigm of "Strengthening the Foundation and Fostering Innovation and Upholding Righteousness and Pioneering Innovation," achieving a dialectical unity of tradition and modernity. This theoretical breakthrough deeply resonates with the "innovation-driven development" strategy and provides methodological support for the living inheritance of intangible cultural heritage. The study achieves three major breakthroughs: enriching the theoretical system of food culture; deciphering the cultural code behind the transformation of traditional handicrafts into modern food industries; and offering a theoretical reference for the cultural construction of characteristic industries under the rural revitalization strategy. Its academic value marks a leap in regional food culture research from phenomenological description to theoretical construction.
