The Effect on the Quality of Lentinula edodes Juice by Vacuum Evaporation Concentration
In order to explore the concentration endpoint of Lentinula edodes juice and the effect of vacuum evaporation concentration on the quality of L.edodes juice,using L.edodes juice as raw material,the soluble solids content and viscosity were determined after concentration to different degrees,and the main component content and antioxidant resistance of L.edodes juice concentrate after reduction were determined.The results showed that the concentration endpoint of L.edodes juice was reached when the soluble solids content was 27 °Brix,after concentration,in addition to the content of free amino acids,the content of main components and antioxidant properties in L.edodes juice concentrate were reduced to varying degrees.The total sugar content was reduced by 7.82％,the total phenolic content was reduced by 15.53％,the total flavonoid content was reduced by 17.92％,the soluble protein content was reduced by 18.21％,the DPPH radical scavenger was reduced by 5.67％,the hydroxyl radical scavenging rate was reduced by 28.57％,and the superoxide anion radical scavenging rate was reduced by 58.47％.
