The invention discloses a preparation method of tartary buckwheat tea with shell, which comprises the following steps: (1) adding tary buckwheat with shell into alkali solution after washing, stirring and soaking at 50 70 C; (2) adding acid to adjust to neutrality; (3) concentrating, drying to less than 5% moisture content of tary buckwheat; (4) putting dried tary buckwheat into vacuum roasting device. Bake in the preparation; (5) the tartary buckwheat after baking is naturally cooled to room temperature, so that the shell buckwheat tea can be obtained. The invention promotes the dissolution of rutin by alkali solution and makes rutin adsorb on the surface of tartary buckwheat hull by means of the adsorption function of Tartary Buckwheat hull. When the final prepared tary buckwheat tea with shell is brewed and drinked, the rutin molecule separates from the surface of the shell and dissolves in water, which can significantly improve the absorption of human body, and is conducive to bringing the nutritive value of tary buckwheat tea into full play. The alkali solution can also extract dietary fiber from tartary buckwheat husk to further strengthen the health care effect. At the same time, it can play the role of tartary buckwheat husk in cancer prevention, anti-cancer, heat clearance and detoxification.

一种带壳苦荞茶的制备方法
本专利技术属于茶饮品
,具体涉及一种带壳苦荞茶的制备方法。
技术介绍
苦荞是自然界中甚少的药食两用作物,苦荞集七大营养素于一身,因为其特殊的生长环境,本身苦荞就富含硒的,可以对人体起到自然补充硒的作用,有着卓越的营养保健价值和非凡的食疗功效。苦荞茶是经过脱壳、晾晒、烘干等工艺制作而成的代用粮食茶,不是传统的茶叶茶,苦荞茶内含人体所需的多种微量元素,如钙、磷、铁、镁、硒等氨基酸,长期饮用,可改善身体状况,降低高血糖、高血压、高血脂的发病率,能有效防治糖尿病,并且具有一定的抗癌作用,是中老年人理想的保健食品。苦荞茶中含有黄酮类物质,其主要成分为芦丁,芦丁含量占总黄酮的70-90%,芦丁又名芸香甙、维生素P,具有降低毛细血管脆性、改善微循环、抗炎、抗病毒等作用,还可抑制醛糖还原酶作用,临床上用于防治脑溢血、高血压、视网膜出血、紫瘢和急性出血性肾炎等。此外,芦丁的抗自由基作用显著,芦丁能很明显地清除细胞产生的活性氧自由基,清除率高达78.1%,远远大于维生素E(12.7%)的作用,而且对·OH的清除作用也大于维生素E,因此,芦丁还有助于抗衰老。虽然苦荞中芦丁含量丰富,但由于芦丁水溶性差,使得传统苦荞茶泡水喝时,芦丁不易溶出,人体吸收量极低,导致苦荞茶无法充分发挥其营养保健价值。
技术实现思路
本专利技术的目的在于:针对上述现有苦荞茶芦丁不易溶出,无法充分发挥其营养保健价值的问题,本专利技术提供一种带壳苦荞茶的制备方法。本专利技术采用的技术方案如下:一种带壳苦荞茶的制备方法,包括以下步骤:(1)将带壳的苦荞麦洗净后加入碱液中,在50-70 ...
【技术保护点】
1.一种带壳苦荞茶的制备方法,其特征在于,包括以下步骤:(1)将带壳的苦荞麦洗净后加入碱液中,在50‑70℃下搅拌后浸泡;(2)加入酸液调节至中性;(3)浓缩,干燥至苦荞麦的含水量低于5%;(4)将干燥后的苦荞麦放入减压烘焙设备中进行烘焙;(5)烘焙后的苦荞麦自然冷却至室温,即得所述带壳苦荞茶。
