摘　　要：乳果糖是一种功能性低聚糖,具有易于被人体吸收、促进对矿物质的吸附、影响骨骼、降低血液中谷氨酸、降低胆固醇等生理功能,有广阔的应用前景。目前,商业化上主要采用化学异构法生产乳果糖。但由于化学异构法存在碱性催化剂的分离、反应副产物多、高能耗等问题,近年来一些学者开展了酶法转化乳糖合成乳果糖的研究。文章综述了乳果糖的基本性质及生产技术研究进展。Lactulose is a typical prebiotic disaccharide. It is easy to be absorbed, promoting the adsorption of minerals, affecting bone, reducting the glutamic acid in the blood and the cholesterol. Ire has a broad application prospect. Commercially available lactulose is produced today mainly through the chemical isomerization of lactose under alkal：ne media. However, the major drawbacks of such chemical isomerization process are requirement of removal of catalysts and byproducts, and high energy consumption. In the last decade, enzymatic bioconversion of lactose into lactulose has been extensively studied to overcome the above-mentioned problems. The progress of basic properties and production technology of lactulose were summarized in this paper.
