红心火龙果富硒红茶复合饮料加工工艺

The Processing Technology of Compound Beverage with Red Pitaya and Selenium Enriched Black Tea

以富硒红茶和红心火龙果汁为原料对红心火龙果富硒红茶复合饮料的加工工艺进行研究。以产品中硒元素含量和感官质量评分为评价指标,通过单因素试验和正交试验,得到红心火龙果富硒红茶复合饮料的最佳制作工艺:在85℃水温下恒温浸提20 min,浸提料液比1︰90(g/mL),所得红茶汤与红心火龙果汁按照1︰0.6比例进行调配。按照此工艺生产所得产品测得硒含量为3.96μg/L,产品色泽均匀且红润,透明度好,茶香浓郁,口感醇厚,酸甜适中且有明显果香。

The processing technology of compound beverage was studied by using selenium-enriched black tea and red pitaya juice as raw materials.Taking the selenium content in the product and the sensory quality score as the evaluation index,through single factor experiment and orthogonal experiment,the best preparation process of the compound beverage with red pitaya selenium-enriched black tea was that the extraction was carried out at a constant temperature of 85℃for 20 min,solid-liquid ratio 1︰90 g/mL,and the obtained black tea soup and red pitaya juice were blended in a ratio of 1︰0.6.The selenium content was 3.96μg/L,the color of the product was uniform and rosy,the transparency was good,the tea fragrance was rich,the taste was mellow,the sweetness and sourness were moderate and there was obvious fruity aroma.
