中文摘要: 紫娟是一种富含花青素的特种茶,具有作为天然食品着色剂的应用潜力。该研究应用高效液相色谱(high performance liquid chromatography,HPLC)测定发现紫娟晒青茶含6种花青素,其中飞燕草色素含量最高,达1.98 mg/g;并通过单因素与正交试验优化,感官评价,建立紫娟茶佛手果脯加工工艺。加工得到的佛手果脯为紫红色、半透明、韧性适中、酸甜适中、有茶味,花青素含量为1.006 mg/g。研究建立一种以紫娟茶作为天然着色剂的紫红色佛手果脯加工方法,具有一定的实际应用价值。
Abstract:Zijuan is a special tea and rich in anthocyanins,which has potential application as a natural food colorant.In this study,six anthocyanins were detected in Zijuan tea by the high performance liquid chromatography(HPLC)method.The content of delphinidin was 1.98 mg/g and higher than others.A technology for the manufacture of preserved bergamot with Zijuan tea was established,through single factor test,orthogonal experimental optimization,and sensory evaluation.The processed preserved bergamot has color of purple-red,appearance of translucent and moderate toughness,taste of moderate sweet-sour,and rich in flavor of tea.The content of anthocyanin in processed preserved bergamot was 1.006 mg/g.In this work,a method for the manufacture of purple-red preserved bergamot using Zijuan tea as natural colorant was established,which has certain value for application.
