双玫汁饮料工艺配方优化研究

Formulation Optimization of Shuangmei Juice Beverage

为研发出香气和口感具佳的双玫汁饮料制作工艺,首先以单因素随机区组实验探索提取玫瑰茄原汁工艺参数,再以此玫瑰茄原汁为原料,分别探索玫瑰花原汁、蔗糖、果葡糖浆、柠檬酸添加量对双玫汁外观品质的影响,在此基础上采用正交设计实验,探索生产双玫汁所需玫瑰花原汁、蔗糖、果葡糖浆、柠檬酸添加量的最优配比。结果表明:(1)料液比、浸提时间、浸提温度、甘草均影响玫瑰茄原汁的感官品质,玫瑰茄原汁提取参数以料液比1:80,浸提时间40 min,浸提温度75℃,甘草添加量0.4%为宜。(2)玫瑰花原汁主要影响双玫汁饮料的玫瑰香味品质,其用量宜在2%～4%;蔗糖主要影响双玫汁饮料的甜度,其用量宜在3%～4%;果葡糖浆主要调节双玫汁饮料的甜味感和减少蔗糖的用量,其用量宜在2%～4%;柠檬酸主要影响双玫汁饮料的酸味舒适感,其用量宜在2%～4%。(3)生产双玫汁饮料最佳调配方案为浓度1.25%的玫瑰茄浸提汁+4%玫瑰花汁+2%蔗糖+2.5%果葡糖浆+0.12%柠檬酸。通过该工艺加工的双玫汁饮料,颜色柔玫红、玫瑰香味诱人,营养丰富。

To explore the techniques for making Shuangmei juice beverage with aroma and taste good,first,the single-factor random block experiment was used to study the process parameters of extracting roselle juice,and then,the roselle juice was used as raw material to clarify the effect of the rose juice,sucrose,fructose syrup and citric acid on the appearance quality of the beverage.Based on this,orthogonal design experiments were carried out to explore the optimal ratio of the original rose juice,sucrose,fructose syrup and citric acid required for the production of the beverage.The results showed that:(1)the ratio of material to liquid,the extraction time,the extraction temperature and licorice all affected the sensory quality of roselle juice,the extraction parameters of roselle juice were:ratio of material to liquid of 1:80,the extraction time of 40 min,the leaching temperature of 75℃,and the adding amount of licorice of 0.4%;(2)rose juice mainly affected the rose flavor quality of Shuangmei juice beverage,and its dosage should be 2%-4%,sucrose mainly affected the sweetness,and its dosage should be 3%-4%,glucose syrup mainly regulated the sweetness and reduced the dosage of sucrose,its dosage was preferably 2%-4%,the citric acid mainly affected the sour taste,and the dosage should be 2%-4%;(3)the best blending scheme for the production of Shuangmei juice beverage was 1.25%roselle extract juice+4%rose juice+2%sucrose+2.5%fructose syrup+0.12%citric acid.The Shuangmei juice beverage processed by this technique process is a healthy flower drink with soft color and rose fragrance.
