摘　　要：柑橘皮渣是柑橘汁加工业的副产物,富含优质膳食纤维。本文研究超高压、超微粉碎和湿热加压等技术对柑橘皮粉和渣粉理化、功能和结构特征的影响,旨在优选一项较好的物理加工技术。结果表明,与其他2种物理处理相比,湿热加压处理的柑橘皮粉和渣粉具有更好的填充性、水合作用、吸附性能、更高的SDF/TDF含量比和更强的体外抗氧化、降血脂和降血糖活性。与未处理的皮粉和渣粉相比,湿热加压处理可以显著提高皮粉的SDF含量,但显著降低渣粉的SDF含量。除此之外,湿热加压后的柑橘皮粉、渣粉显示出略深的颜色,可能会限制其在浅色食品中的应用。这些研究发现可为作为功能性食品原料的高品质柑橘纤维的开发提供新的视角。Citrus peel and pomace are by-products of citrus juice processing industry and are known for their abundance of high-quality dietary fiber.However,the traditional method of preparing citrus fiber involves the use of chemicals,which not only contributes to environmental pollution but also results in resource wastage.In light of the principle of comprehensive utilization,this study seeks to develop a physical processing technique for citrus fiber concentrate.The physicochemical,functional,and structural characteristics of citrus peel and pomace powders following modification through ultra-high pressure,superfine grinding,and soaking-autoclaving treatments are investigated,respectively.Compared with ultra-high pressured and superfine ground citrus peel and pomace powders,soaking-autoclaved counterparts exhibit superior physicochemical and functional properties,albeit slightly darker color that might impose limitation on their utilizations in light-colored food products.These findings offer new perspectives on how to prepare high-value citrus fiber concentrateas functional food ingredients.
