无核黄皮脱苦工艺探索

Study on the Technology of Debittering of None-nuclear Clausena lansium

以郁南无核黄皮作为原料,分别用糖化酶和超声波对无核黄皮进行脱苦处理,以总黄酮的去除率为评价脱苦的指标,探究无核黄皮脱苦工艺。结果表明,在酶添加量0.25%,酶作用时间4 h时的无核黄皮脱苦率达69.8%;在pH值6,超声时间90 min,料液比1∶1 (g∶m L)条件下,无核黄皮脱苦率达65.8%。

With fresh Clausena lansium as a raw material,the glucoamylase treatment and ultrasonic treatment methods,which used removal rate of total flavonoid as the index were used to study on debitterizing of Clausena lansium.The reaults were obtained as follows:the adding amount of glucoamylase was 0.25%,and treatment time was four hour.Under the above conditions,the removal rate of flavanone reached up to 69.8%.Under the condition of material-to-liquid ratio 1∶1(g∶mL),ultrasonic treatment time 90 min,under the condition of pH value was 6,the remove rate of flavanone was 65.8%.
