Zusammenfassung:	The invention discloses a fresh-keeping method of fresh-cut water chestnuts. The fresh-cut water chestnuts are obtained through ozone water pre-sterilization, heat treatment of whole fruits, pre-cooling, low-temperature water cleaning, soaking with fresh-keeping liquid and vacuum packaging. The fresh-keeping liquid used in the method has the effects of sterilization, bacteriostasis and corrosion prevention, and meanwhile can effectively inhibit phenylpropane metabolism of the water chestnuts and reduce accumulation of flavonoid substances, so that the yellowing degree and the weight loss rateof the fresh-cut water chestnuts in a storage process can be reduced, the influence on the taste of the water chestnuts is small, and the storage life under the storage condition of 4 DEG C can reach20 days or more; and the requirements of long-distance transportation and sales are basically met. 一种鲜切马蹄的保鲜方法。本发明通过臭氧水预杀菌、整果热处理、预冷、低温水清洗、保鲜液浸泡和真空包装，得到鲜切马蹄。由于本发明的保鲜液具有杀菌、抑菌和防腐的功效，同时，能够有效抑制马蹄的苯丙烷代谢，减少黄酮类物质的积累，因而能使鲜切马蹄在贮藏过程中黄化度和
