| 摘 要： | 主要研究了2种杀菌方式对蓝莓汁品质的影响。一种是550 MPa、5 min的超高压杀菌,另一种是121℃、5 s的高温瞬时杀菌。通过测定杀菌后蓝莓汁的菌落总数、悬浮稳定性、色差值、花色苷含量和理化性质等指标,证实超高压杀菌在杀菌的同时较好地保持了蓝莓汁原有的品质、色泽及营养。

Effect of Short Time Sterilization with High Hydrostatic Pressure and High Temperature on the Quality of Blueberry Juice |

| Abstract: | The impact of the two sterilization methods on the quality of blueberry juice was studied in this paper.One method was high hydrostatic pressure sterilization at 550Mpa for 5min,and another was high temperature short time sterilization at 121℃ for 5s.Based on the detection of total colonies number,suspension stability,color value,anthocyanin content,and physical chemical indicators of blueberry juice after sterilization,we believed that the high hydrostatic pressure sterilization was better in keeping quality,color and nutrition of blueberry juice. |
