淫羊藿保健露酒的研制及其功能评价

Development and functional evaluation of healthy wine containing Epimedii Folium

用热水浸提法制备淫羊藿提取液,以发酵的葡萄酒为酒基,辅以适量白砂糖和柠檬酸,研制出一种淫羊藿保健露酒.结果表明:当固液比为1∶30,浸泡1.5h,于80℃水浴4h时,淫羊藿总黄酮提取率最高;在葡萄酒中添加25.0%淫羊藿提取液、20.0%白砂糖和0.1%柠檬酸时,淫羊藿保健露酒的感官品质最好;淫羊藿保健露酒中总黄酮、淫羊藿苷、朝藿定A、朝藿定B、朝藿定C质量浓度分别为297.08、16.64、18.57、25.23、7.89mg/L;与普通葡萄酒相比,淫羊藿保健露酒的抗氧化活性更强.该生产工艺所得淫羊藿保健露酒兼具优良的感官品质及较好的保健功能.

A new type of healthy wine containing Epimedii Folium was developed with fermented wine, granulated sugar, citric acid and extract of Epimedii Folium. The extraction yield of total flavonoids from Epimedii Folium was the highest under the following conditions： ratio of solid to liquid of 1 ： 30, soaking time 1. 5 h, extraction time 4 h and extraction temperature 80℃. Sensory quality of healthy wine was relatively high when the base of fermented wine was mixed with 25.0% Epimedii Folium extract, 20.0% sugar and 0. 1% citric acid. The contents of total flavonoids, icariin, epimedin A, epimedin B and epimedin C in healthy wine were 297.08, 16.64, 18.57, 25.23 and 7.89 mg/L, respectively. Compared with the traditional wine, healthy wine containing Epimedii Folium possessed superior sensory properties and stronger antioxidant activity, which showed a potential for becoming an alternative functional food.
