Extraction method of citrus fibers

The invention discloses an extraction method of citrus fibers, and relates to the technical field of fiber processing. Processing methods of acid treatment, ultrasonic assistance, sodium chlorite oxidation, instant high-pressure expansion and an ultrafine crushing technology are adopted to form modify fibers which are arranged closely and orderly in citrus, and the modified citrus fibers become loose, porous, more hydrophilic groups are exposed, the fibers are enabled to have good water retention, expansibility, oil retention, emulsibility and ion adsorption capacity, and the range of application of the citrus fibers in the food industry is broadened. 本发明公开了一种柑橘纤维的提取方法，涉及纤维加工技术领域，本发明通过采用酸处理、超声辅助、亚氯酸钠氧化、瞬时高压膨化、超微粉碎技术处理方式，对柑橘中排列紧密有序的纤维进行改性，改性后的柑橘纤维变得松散、多孔、暴露出更多的亲水基团，使其具有良好的保水性、膨胀力、持油力、乳化性和离子吸附能力，从而拓宽柑橘纤维在食品工业中的应用范围。
