玉米须复合袋泡茶的研制

Development of Corn Silk Composite Tea Bags

摘要: 玉米须具有丰富的药用价值和经济价值，是一种具有开发潜力的自然资源。本文以玉米须为主要原料，以山楂、茯苓和红枣为辅料，研制出一款具有利尿消肿、健脾和胃等保健功能的复合袋泡茶。通过单因素和正交试验优化了其原料配比和冲泡工艺。结果表明：当玉米须为2.5 g，山楂为0.5 g，茯苓为1 g，红枣为2.5 g，采用玉米纤维袋，90℃温度下冲泡时间为5 min时茶汤清澈透明，色泽呈浅黄褐色，有玉米须清香，口感协调；水分含量、水浸出物含量和总灰分含量等理化指标均符合相关标准规定。本文的研究结果对玉米须、山楂、茯苓和红枣中的活性物质的充分利用，复合袋泡茶种类的扩展，袋泡茶的食品功能性开发提供了参考价值。

Abstract: Corn silk has rich medicinal and economic values, and it is a natural resource with development potential. In this paper, corn silk was used as the main raw material, and hawthorn, poria and red jujube were used as auxiliary materials, and a composite tea bag with health care functions such as diuresis and swelling, spleen and stomach was developed. The ratio of raw materials and brewing process were optimized through single-factor test and orthogonal test. The results showed that when the amount of corn silk was 2.5 g, hawthorn 0.5 g, Poria cocos 1 g, and red dates 2.5 g, using a corn fiber bag, the tea soup was clear and transparent with a light yellowish-brown color after 5 minutes of brewing at 90˚C, featuring the fresh fragrance of corn silk and harmonious taste. Physical and chemical indicators, including moisture content, water extract content and total ash content, all met the relevant standard requirements. The research results provided reference value for the full utilization of active substances in corn silk, hawthorn, poria cocos and red dates, the expansion of compound bagged tea types, and the functional development of bagged tea as food.
