澄清无花果果汁饮料的研制

Development of a clear Ficus carica L.juice drink

以无花果果干为原料研制澄清无花果果汁饮料。在单因素试验的基础上,采用正交试验确定无花果果汁饮料的最佳配方,同时对无花果果汁进行吸光度测试,以此来确定澄清效果。结果表明,澄清无花果果汁饮料的最佳生产方案为:30g无花果果干榨成汁100g,4℃冷澄清6h,加入0.3g50%的糖浆、0.5g0.5%的柠檬酸。所制得的无花果果汁饮料色香味俱佳,澄清透明,易于被大众接受。

With dried Ficus carica L fruit as the raw material, a clear juice drink was developed. Based on single-factor experiments, orthogonal experiments were conducted to determine the optimum formula of the drink. At the same time, the absorbance of Ficus carica L. juice was measured to confirm the clarification effect. The results showed the optimal method of making the drink as： 100 g juice extracted from 30 g dried Ficus carica L. fruit was clarified at 4 ~C for 6 h, to which 0.3 g 50% syrup and 0.5 g 0.5% citric acid were added. The drink obtained, characterized by satisfactory color, flavor and taste as well as clear appearance, was highly acceptable to consumers.
