Abstract: 【Objective】 To provide technical support for promoting the sustainable development of the prune industry in Xinjiang, the high-quality development of the prune preservation and processing industry was explored, and the innovative layout of related key technologies was analyzed. 【Methods】 The preservation and processing technologies of prunes are systematically introduced and their demand and development potential in domestic and international markets are assessed through industrial research and literature policy analysis.In addition, deficiencies in current freshness processing technologies were analyzed and key technological innovations in related fields were investigated. 【Results】 Xinjiang's prunes have great potential in domestic and international markets due to their unique flavor and nutritional value.However, there are many deficiencies in the existing preservation and processing technologies, resulting in poor post-harvest preservation of prunes, homogenization of processed products, short industrial chain and other problems, seriously affecting the sustainable development of the prune industry and economic benefits and market competitiveness.The research and development of advanced processing and preservation technology can enrich the diversification of prune products, improve the preservation effect of prunes and enhance the competitiveness of the market. 【Conclusion】 The high-quality development of Xinjiang prune preservation and processing industry needs to rely on scientific and technological innovation to promote industrial technology upgrading, and promote product diversification and marketing.
