A black tea-like processing method for seabuckthorn leaves includes withering, rolling, fermentation and drying steps. Its characteristics are as follows: the seabuckthorn leaves in withering step are shady-dry, i.e. covered with covering cloth on the surface of seabuckthorn leaves accumulated or laid flat; in rolling step, an electric heat pipe is installed on the lower surface of the grinding plate under the kneading machine, a heat shield is installed on the outer surface of the electric heat pipe, and the temperature of the lower grinding plate is controlled at 50 60 C, and kneading. The pressure control of the cover of the twister is 1 1.5 kg and the rolling time is 10 minutes; the fermentation chamber in the fermentation step is hexahedron, each side is double-decked pine board compartment structure, each compartment is filled with salt layer, hypoxic drying fermentation for 6 hours; the drying step is static drying, i.e. the seabuckthorn leaves are static paved in the oven and dried by hot air. The advantages are that the seabuckthorn leaves are curled like black tea, easy to brew, high leaching rate and high medicinal efficacy. During the fermentation process, there will be no peculiar odor or cross-flavor.

沙棘叶的类红茶式加工方法
:本专利技术涉及沙棘叶饮品加工,特别是沙棘叶的类红茶式加工方法。
技术介绍
:藏医巨著《四部医典》中系统地记载了沙棘的药效:增加血红蛋白、防治心脑血管系统疾病,提高抗衰老机能,对各种维生素缺乏症特别有疗效。沙棘具有补脾健胃、清热、止泻、治疗溃疡、祛痰止咳、平喘、抗炎生肌、提神、抗疲劳的作用。据中科院西北高原生物研究所的最新研究发现,沙棘还可防治癌症,并有美容的功效。沙棘中含有多种氨基酸、维生素及甘露醇。沙棘叶饮品中富有大量的菊粉,能在大肠里大量繁殖双歧杆菌,减少肠内有害细菌,增强人体免疫能力,维护神经系统的正常动作。另外菊粉可减少体内有毒物质的产生,减轻肝脏分解毒素的负担;促进人体对钙、锌等矿物质吸收。现有沙棘叶饮品加工方法是将采集到的沙棘叶自然晾干后进行粉碎、细粉小袋包装。饮用时用开水冲泡袋包。这种袋装的包装袋孔隙小(以防粉漏),所以浸泡时包装袋会起着阻挡出味作用,降低药效。同时包装袋材质也会有化学物质析出浸泡在热水中。茶叶加工方法以是否有发酵步骤区分,没有发酵步骤为绿茶,浸泡液显绿色;有发酵步骤的为红茶,浸泡液为红色。而沙棘叶袋装茶其 ...
【技术保护点】
1.一种沙棘叶的类红茶式加工方法,包括萎凋、揉捻、发酵、烘干步骤,其特征在于:萎凋步骤中的沙棘叶为阴干,即在沙棘叶堆积或平铺的表面上覆盖有遮盖布;揉捻步骤中在揉捻机下磨盘下表面安装有电热管1,电热管外围安装有隔热罩2,下磨盘3控温为50‑60℃,揉捻机压盖6的压力控压为1‑1.5kg,揉捻时间为10分钟;发酵步骤中的发酵室为六面体,每单面皆为双层松木板9的隔腔结构,每个隔腔中填充有盐巴层10,少氧干发酵6小时;烘干步骤中为静态烘干,即在烘干箱内沙棘叶静态平铺以热风吹扫烘干。
