The invention relates to a production process of Jinhua Begonia Tea, which is bottled with PDA potato culture medium, inoculated with 4 to 6 pieces of Jinhua fungus, cultured in static culture and shaking bed to produce liquid Jinhua fungus, cleaned, dried or dried Begonia leaves, soaked in boiling water, filtered and retained filtrate for black tea, soaked in black tea filtrate, salvaged and then filled with polypropylene film bag to sterilize Jinhua fungus. The liquid strains were inoculated on the leaves of Begonia crabapple, cultured and fermented until the leaves of Begonia crabapple were covered with Golden Flower Fungi inside and outside the culture medium, and then dried and packed to obtain Golden Flower Begonia Tea. The invention uses the leaves of Begonia hupehensis unique to Shennongjia as raw materials, inoculates the Golden Flower fungus into the treated Begonia tea for fermentation, and after the Golden Flower fungus fermentation, can degrade tannins, alkaloids and other components, so as to degrade starch. The Golden Flower crabapple tea brewed by the invention has brown-red color, no coarse green taste of traditional crabapple tea, sweet taste, and has the functions of promoting digestion, lowering blood lipid, dissolving fat, regulating sugar metabolism, etc.

一种金花海棠茶生产工艺
:本专利技术属于食品发酵领域,具体涉及一种金花海棠茶生产工艺。
技术介绍
:冠突散囊菌(Eurotiumcristutum)俗称"金花菌",属于散囊菌目发菌科散囊菌属的一种真菌,常见生长于黑砖茶上,属益生菌。经科学研究,冠突散囊菌能分泌茶叶中的淀,粉酶和氧化酶,可催化淀粉转化为单糖,多酚类化合物质氧化,使茶叶汤色变棕红,消除粗青味。在口味上更加醇和爽口,甜滑回甘。它具有较强的促消化、降血脂、溶解脂肪、调节糖类代谢等功效。其颗粒的大小会随着湿度等因素变化而发生变化,茂盛的时候似"米兰",萎缩时会变小,甚至变成白色的小斑点。湖北海棠(Malushupehensis(Pamp.)Rehd.)隶属于蔷薇科苹果属落叶小乔木,主产湖北,湖北海棠一般在夏秋两季采叶,经干燥处理后可得海棠叶茶,传统海棠茶加工工艺简单,一般经过简单干燥后包装,食用时直接泡水喝,对其中功能成分在加工过程中的变化缺乏研究,加工工艺急需改进。由于海棠叶中含有单宁、生物碱等物质,传统海棠茶较涩口。CN101011096A公开了一种湖北海棠茶,由湖北海棠的叶、果及甘草、桑叶、鱼腥草、野山楂查、玉米须、荷花、荷叶等辅料经粉碎灭菌后得到。CN104839382B公开了一种灵芝海棠茶,菌种活化:从菌种库中取出灵芝菌种,接种于土豆上,摇床振荡培养制得活化的菌种;接种活化的菌种制作种子培养液:葡,将海棠茶叶装入培养容器中用水浸润,在无菌条件下接种种子培养液制得灭菌后的海棠发酵茶叶;灵芝粉与海棠发酵茶叶混合后,再次粉碎过筛,制备灵芝海棠袋泡茶。

【技术保护点】
1.一种金花海棠茶生产工艺,其特征在于:具体实施步骤如下: 1)PDA土豆培养基装瓶,接种4‑6个金花菌菌块,静止培养、摇床培养至菌种较粘稠并有 菌球出现,制作出金花菌液体菌种; 2)海棠叶采收后清洗干净,50℃烘干或晒干备用; 3)将黑茶用开水浸泡,黑茶添加量为0.5‑1%,浸泡时间30‑60min,浸泡后过滤掉茶叶, 滤液备用; 4)将步骤2)烘干的海棠叶浸泡于步骤3)所得的滤液中浸泡60‑90min; 5)将步骤4)浸泡的海棠叶捞出后装聚丙烯薄膜袋,然后121℃灭菌30min,装样量为每 袋800‑1000g; 6)将步骤1)所得的金花菌液体菌种接种到步骤5)袋中的海棠叶上,接种量为20‑30ml 每袋,20‑25℃培养发酵20‑25d,此时,海棠叶培养基内外布满金花菌; 7)将经步骤6)培养发酵的海棠叶烘干后包装,即得金花海棠茶。
