梨渣膳食纤维提取改性及应用研究

膳食纤维有助于促进人体消化吸收、预防心血管疾病、控制血糖等。梨渣是梨果经榨汁、酿造后得到的副产品。梨渣中膳食纤维含量丰富,可作为食品膳食纤维的优质来源。但因梨渣中石细胞含量高,适口性差,造成大量浪费。如若改进梨渣中膳食纤维的提取方法,再进行加工、改性,可大大提高梨渣膳食纤维的利用率,增加其利用价值。本文概述了梨渣膳食纤维的提取及改性方法,总结了梨渣膳食纤维在食品中的应用,并对梨渣膳食纤维的发展前景进行了展望,以期为提高梨渣的综合利用率和梨渣膳食纤维的深入研究提供一定的参考。

Research Progress on Extraction and Modification and Application of Dietary Fiber from Pear Residue

Dietary fiber helps to promote the digestion and absorption of human body,prevent cardiovascular diseases,control the blood levels of glucose and so on.Pear residue is a by-product of pear after being squeezed and brewed.Pear residue is rich in dietary fiber,which can be used as a good source of dietary fiber.But pear residue contains a large number of stone cells,causing the poor palatability.So it is difficult to use as feed,resulting in a huge waste of resources.If the method of extracting the dietary fiber of pear residue is improved,then processed and modified,the utilization of dietary fiber of pear residue can be greatly improved and its value can be increased.Therefore,this paper summarized the extraction and modification methods of the dietary fiber of pear residue,and its application in food,and prospected the development outlook of pear residue dietary fiber in the future,in order to provide some references for increasing its rate of multipurpose utilization and the in-depth study of pear residue dietary fiber in the future.
