无麸质食品品质改良与功能提升关键技术研究进展

Research Progress of Key Technologies for Quality Improvement and Functional Enhancement of Gluten-Free Food

摘要: 无麸质食品作为麸质不耐受和乳糜泻患者必需的膳食替代品，其研究范畴已从单一原料替代拓展为涵盖病理机制、原料开发、加工技术、品质改良及安全控制多方面的系统性领域。本文系统综述了该领域的最新研究进展：在机制层面，重点剖析了麸质引发的免疫机制与肠道菌群的相互作用，揭示了乳糜泻症状持续存在的潜在根本原因。在原料与加工方面，关注传统谷物、杂粮、及加工副产物的高值化利用，并结合多种绿色加工技术，有效提升产品的质构与营养品质。在品质改良方面，阐明亲水胶体、蛋白质改良剂及功能性成分通过协同复配作用模拟了麸质网络结构，从而提改善产品持气性与口感；在安全性控制方面，综述了覆盖生产、加工、流通全链条的交叉污染防控体系。总体而言，尽管无麸质市场持续扩大且消费需求日趋多元，但仍面临原料成本高与产品品质不均等挑战。因此，未来研究方向应聚焦于菌群–免疫机制解析、低成本绿色加工技术创新、标准化评价体系建立以及精准营养模式的推广应用，以推动无麸质食品向功能化、个性化与可持续化方向发展。

Abstract: As essential dietary alternatives for individuals with gluten intolerance and celiac disease, research on gluten-free foods has long expanded from the simple replacement of single ingredients to a systematic field covering pathological mechanisms, raw materials, processing technologies, quality improvement, and safety control. By reviewing relevant literature, this paper provides a systematic overview of the latest research progress on gluten-free foods, with a focus on analyzing the immune mechanisms leading to gluten intolerance and their interaction with the gut microbiota, further uncovering potential fundamental reasons for the persistent symptoms of celiac disease. Regarding raw materials, research focuses on the high-value utilization of diversified ingredients such as traditional grains, coarse grains, and by-products, combined with various green processing technologies, significantly enhancing the texture and nutritional characteristics of gluten-free foods. In terms of quality improvement, the synergistic combination of hydrocolloids, protein modifiers, and functional components effectively simulates the gluten network structure, thereby improving the product’s gas retention and mouthfeel. For safety control, not only has a cross-contamination prevention system covering the entire chain from production, processing, to circulation been established, but approaches to further reducing hazard risks and ensuring the safety of gluten-free foods have also been proposed. Overall, the current gluten-free market continues to grow, and consumer demand is showing diverse trends, but challenges such as high raw material costs and uneven product quality remain. Therefore, future research should focus on elucidating microbiota-immune mechanisms, developing low-cost green processing technologies, establishing standardized evaluation systems, and promoting precise nutrition models, driving gluten-free foods toward functionalization, personalization, and sustainability, providing new ideas for healthy food development.
