摘要
本实验以西洋参支根、黄芪、枸杞、洛神花为主要原料制备西洋参袋泡茶,采用单因素结合正交试验确定西洋参袋泡茶的最佳配方;并以DPPH清除率为指标,利用响应面法优化冲泡条件,得到了西洋参袋泡茶的最佳冲泡工艺。结果表明,西洋参袋泡茶的最佳配方为西洋参0.5 g、黄芪0.2 g、枸杞1.1 g、洛神花0.3 g。在不影响感官的前提下,加水量120 mL、温度93℃下冲泡10 min、冲泡1次时的整体抗氧化性最佳。制得的西洋参袋泡茶利水消肿、益气固表、生津益血,具有较好的保健功效。
This experiment used American ginseng roots, astragalus, wolfberry, and Luoshen flower as the main raw materials to prepare American ginseng tea bags. The optimum formula of American ginseng tea bags was determined by single factor combined with orthogonal test. Taking DPPH scavenging rate as index, response surface methodology(RSM) was used to optimize the brewing conditions, and the best brewing technology of American ginseng bag tea was obtained. The results showed that the best formula of American ginseng bag tea was American ginseng 0.5 g, Astragalus membranaceus 0.2 g, Lycium barbarum 1.1 g and Luoshen flower 0.3 g. Under the premise of not affecting the sensory, the overall antioxidant activity was the best when the amount of water was 120 m L, the temperature was 93 ℃, the brewing time was 10 min, and the brewing times was 1. The prepared American ginseng bag tea has good health care effects, such as benefiting water and detumescence, tonifying qi and strengthening exterior, generating fluid and benefiting blood.
