一种咖啡原料的处理方法及处理系统 技术领域
本发明涉及咖啡原料处理技术, 尤其涉及一种咖啡原料的处理方法,包含 制曲、 发酵、 分离出咖啡豆及附属产品的方法。 背景技术
目前, 咖啡产品作为公众越来越青睐的饮品, 其需求日益增大, 同时, 消 费者对咖啡的营养、 咖啡的味道要求也越来越高, 所以需要对咖啡的营养、 咖 啡的香味进行加工改善。要想改善咖啡产品的营养和香味、就需要创建一套科 学的、 全新的加工技术和方法。现今, 绝大多数咖啡加工企业是通过烘焙处理 的加热温度、 加热时间来改善咖啡豆的香味。但是, 要想改善咖啡豆的营养和 香味, 仅仅依靠烘焙处理来改善还是不够的。
为了进一歩满足消费者的需求,可以用微生物发酵的方法来加工改善咖啡 豆的营养和香味。 咖啡豆通过微生物发酵后, 蛋白质、 脂肪、 糖类、 等物质都 将会发生变化,通过微生物酶解的作用: 大分子蛋白质可以水解成小分子肽或 氨基酸; 脂肪可分解成甘油和脂肪酸; 部分糖类通过酶解和合成、 可转化成醇 类和酯类; 许多物质将会变化的更加营养和有益, 更加有利于胃肠的消化和吸 收; 通过微生物酶解的作用脂肪可水解成甘油和脂肪酸, 甘油可进一歩转化为 有机酸, 有机酸与糖类转化的醇类可以合成各种酯类, 咖啡豆的香味就会变得 更加醇香浓郁, 或品或饮、 会令消费者回味无穷, 会让消费获得满足满意。
中国发明专利 CN200480030833. 7公开了一种生咖啡豆的处理方法, 该方 法包括发酵处理和分离处理,发酵处理使来源于咖啡果实的未粉碎种子生咖啡 豆和微生物、 以及可被所述微生物分解的可分解行成分相接触进行发酵处理, 分离处理把所述的发酵处理完的生咖啡豆挑选出来。 由于其仅仅通过 "简便" 的发酵和分离处理, 来改善咖啡豆的香味, 即将咖啡豆通过微生物和培养基一 次发酵。一次发酵, 发酵酶对咖啡豆的酶解不会充分。在许多固体物发酵实践 中得到的证实是: 一次发酵, 发酵酶对固体物产品的酶解不会充分, 无法满足 消费者除了对咖啡的香味有要求外,更注重咖啡的营养和安全等方面越来越高 的要求, 而且, 发酵基的成分会影响到咖啡豆的香味和口味, 还有该方法在发
酵处理后仅提取曲醅中的咖啡豆, 而将其他物质丢弃, 造成资源的浪费。
通俗来说, 微生物包括细菌、 病毒、 真菌等。
真菌 (Fungus ) 分为三类: 酵母菌、 霉菌和蕈菌 (大型真菌)。
霉菌, 是形成分枝菌丝的真菌的统称。 构成霉菌体的基本单位称为菌丝, 呈长管状, 宽度 2〜10微米, 可不断自前端生长并分枝。大量菌丝交织成绒毛 状、 絮状或网状等, 称为菌丝体。 菌丝体常呈白色、 褐色、 灰色, 或呈鲜艳的 颜色, 菌落为白色毛状的是毛霉, 绿色的为青霉,黄色的为黄曲霉, 有的可产 生色素使基质着色。 霉菌繁殖迅速, 常造成食品、 用具大量霉腐变质, 但许多 有益种类已被广泛应用, 是人类实践活动中最早利用和认识的一类微生物。
曲霉 (Aspergi l lus)是发酵工业和食品加工业的重要菌种, 2000多年前, 我国就用于制酱, 也是酿酒、 制醋曲的主要菌种。现代工业则利用曲霉生产各 种酶制剂、 有机酸, 以及农业上的糖化饲料。现代工业利用曲霉生产各种酶制 齐 1」、 有机酸, 农业上用作糖化饲料菌种。 例如黑曲霉、 米曲霉等。 米曲霉是一 类产复合酶的菌株,将原料中淀粉降解将不易消化的大分子蛋白质降解, 而且 可以使辅料中粗纤维、 植酸等难吸收的物质降解, 提高营养价值、保健功效和 消化率, 广泛应用于食品、 饲料、 生产曲酸、 酿酒等发酵工业, 并已被安全地 应用了这么多年。
米曲霉基因组所包含的信息可以用来寻找最适合米曲霉发酵的条件,这将 有助于提高食品酿造业的生产效率和产品质量。
根霉菌 (Rhizopus ) 分布广, 约 10种以上, 本发明选用其中的米根霉, 对人无害, 食用甜酒药及糖化饲料就是选用此菌制备的。
微球菌(Micrococcus Cohn, 1872),细菌的一科。 如微球菌属, 为不运动的 专性好氧细菌, 多见于土壤和水中, 也见于人和动物的皮肤上, 为非致病菌。
正是由于某些微生物本身就对人体有害,所以,利用微生物发酵处理食品 和饮品, 需要相当慎重,选择安全的有益的微生物参与作为食品饮品发酵过程 非常重要,一旦选择微生物不当,可能导致疾病甚至造成及其恶劣的严重后果。 发明公开

本发明的技术效果如下:

图 1是本发明的咖啡原料的处理方法流程图;
图 2是本发明的第一实施例的咖啡原料的处理方法流程图;
图 3是本发明的第二实施例的咖啡原料的处理方法流程图;
图 4是本发明的第三实施例的咖啡原料的处理方法流程图;
图 5是本发明的咖啡原料的处理系统示意图。 实现本发明的最佳方式
下面结合附图和具体实施例对本发明技术方案进行详细的描述。
首先需要进行下面 2个歩骤:
1、 咖啡原料分选:
咖啡原料包括: (1 ) 咖啡果实: 带有皮壳的原摘的果实; (2) 生咖啡豆: 去皮带壳的咖啡豆; (3 ) 不带皮壳的咖啡仁; 以及 (4) 上述的 "咖啡果实"、 "生咖啡豆"和 "咖啡仁", 经蒸熟处理的熟咖啡豆。
为了获得更好的咖啡豆, 生产更好产品, 可以对咖啡原料通过分选机进行 分选, 获得符合条件要求的标准咖啡豆。
2、 杀菌处理:
当用微生物进行发酵处理前,存活于生咖啡豆或咖啡果实上的细菌会造成 污染问题。用受到污染的生咖啡豆或咖啡果实进行接种发酵就会产生杂菌, 发 酵的咖啡产品就没有质量保障。 如生咖啡豆或咖啡果实受到黄曲霉菌污染时, 发酵的咖啡豆产品就会产生黄曲霉毒素, 这样的咖啡豆就不能食用。
为了获得既营养美味、又确保安全的咖啡豆产品,对分选后的生咖啡豆或 咖啡果实进行发酵前的杀菌处理, 杀菌方法包括 2种:
1 ) 蒸豆: 将生咖啡豆或咖啡果实经过蒸汽处理, 杀死附着于或存活于咖 啡豆或咖啡果实上的微生物, 除掉咖啡豆或咖啡果实上附着污染的杂菌。蒸豆 的设备采用带有蒸屉网的密闭式蒸气锅,为了生产安全蒸锅需设有排气防爆装 置。 锅内蒸汽的温度: 80°C-12rC, 121 °C所需时间: 30分钟; 低于 121 °C所 需时间需要长一些。这样的条件可以有效的杀死存活于咖啡豆或咖啡果实上的 杂菌, 并可绝对保障发酵产品的质量和安全。 为了取得较好的效果, 在蒸豆之 前对干豆要进行泡豆, 条件是 40度水, 直到泡涨泡透。 本方法可获得无微生 物污染的蒸熟的咖啡果实或熟咖啡豆。熟咖啡豆在随后的工艺中, 具有发酵时 间短等优势, 熟化的咖啡豆更有利于发酵和酶解。
2) 超高压 (冷温) 杀菌:
对于咖啡果实或生咖啡豆, 采用超高压力一般在为 200〜600MPa之间, 多种生物体经 200MPa以上加压处理即会出现生长迟缓, 甚至死亡。一般情况 下, 寄生虫的杀灭和其它生物体相近, 只要低压处理即可杀死, 无芽孢细菌、 酵母、 霉菌的营养体在 300〜500MPa压力下可被杀死, 而芽抱杆菌属和梭状 芽孢杆菌属的芽孢对压力比其营养体具有更强的抵抗力,需采用更高的压力才 会被杀灭。 微生物在 600MPa的高压下、 瞬间就会致死。 压力处理的时间与压
力成反比, 压力越高, 处理所需的时间越短。
超高压杀菌, 是一个纯物理过程, 具有瞬间压缩、 作用均匀、 操作安全、 冷温低耗、 有利于环保的特点。用超高压技术处理食品, 可达到高效杀菌的目 的, 且对食品中的维生素、色素和风味物质等低分子化合物的共价键无明显影 响。
超高压杀菌可获得无微生物污染的咖啡果实或生咖啡豆。
图 1是本发明的咖啡原料的处理方法流程图。 如图 1所示, 该方法包括: S100, 杀菌歩骤: 对咖啡原料进行杀菌处理, 得到无菌咖啡原料; S200,制曲发酵歩骤:将所述无菌咖啡原料与由豆腐或咖啡粉制作的发酵 基混合均质 (混合均匀) 后, 接种有益微生物发酵菌菌, 得到曲醅;
( 1 ) 将豆腐打成豆腐茸为发酵基, 接种有益微生物发酵菌, 接种后与无 菌咖啡原料混合均质 (混合均匀), 均质后得到曲醅;
(2) 将咖啡豆研磨成咖啡粉为发酵基, 接种有益微生物发酵菌, 接种后 与无菌咖啡原料混合均质 (混合均匀) , 均质后得到曲醅;
(3 ) 将无菌咖啡原料直接喷洒接种有益微生物发酵菌, 接种后混合均质
(混合均匀) ; 均质后得到曲醅;
S300, 发酵歩骤: 在曲醅中添加辅料后进行发酵;
S400, 分离歩骤: 分离出咖啡豆与剩余物。分别对应于上述制曲发酵歩骤 则为:
( 1 ) 分离出咖啡豆及剩余物, 剩余物制成植物奶酪;
(2) 分离出咖啡豆与剩余物, 主要为咖啡粉, 将咖啡粉制成速溶咖啡。
(3 ) 分离出咖啡豆与剩余物, 主要为菌丝, 将菌丝制成美味的速溶咖啡 添加剂。
S500, 干燥歩骤: 将分离出的咖啡豆进行智能化的低温微波真空干燥。 图 2是本发明的第一实施例的咖啡原料的处理方法流程图。 如图 2所示, 咖啡原料的处理方法包括如下歩骤:
S1100, 杀菌歩骤: 对咖啡原料进行杀菌处理, 得到无菌咖啡原料; S1200, 发酵基制作歩骤: 将食用豆腐打成豆腐碎茸, 然后将该豆腐碎茸 与咖啡豆拌均装盒制曲。
制作普通的食用豆腐的凝固剂的种类有:石膏、 卤水、葡萄糖内酯等。 因
为石膏、 卤水、 葡萄糖内酯等在酿造中会影响到产品的口味。所以, 在本发明 中使用 "发酵水"。 该发酵水的制作很简单, 用做豆腐的黄浆水自然陈化, 通 过微生物的发酵作用就会产生酸水, 酸水即 "发酵水"。
S1300 , 制曲发酵歩骤: 在豆腐茸发酵基上接种有益微生物发酵霉菌, 包 括接种毛霉菌、根菌或者微球菌,接种后与无菌咖啡原料混合均质 (混合均匀), 均质后得到曲醅;
制曲发酵歩骤:采用喷洒接种的方式接种毛霉菌,制曲时,制曲车间温度: 22-26度, 接种 28小时左右上下翻动, 大约 36-48小时当菌丝生长茂盛后成淡 黄色或略褐色时出醅。
S1400 , 二次发酵歩骤: 在曲醅中添加辅料 (包括增加香味剂: 如玫瑰花 提取物、 茉莉花提取物、 香桂花提取物) 后进行发酵;
发酵歩骤, 将毛霉制曲产生的曲醅, 搅拌均匀, 添加辅料, 包括增加香味 齐 (J: 如玫瑰花提取物、 茉莉花提取物、 香桂花提取物, 或者略加红酒或白酒均 质后装入发酵装置 (如发酵罐等), 进行发酵。 制作红色咖啡豆可加红曲, 制 作白色咖啡豆可加白曲。
发酵温度控制在 40度以内, 发酵时间不小于 7天。
发酵装置 (如发酵坛、 罐、 缸等) 要设有检测装置, 用来检测温度、 PH 值、 糖度、 乙醇、 溶氧、 空气流量、 罐压、 转速等参数, 还要包括取料检测、 酸碱调节装置、 在线检测及在线上传设备。
S1500 , 分离歩骤: 分离出咖啡豆及剩余物, 剩余物制成植物奶酪; 分离歩骤,采用直立式粘稠物振动筛进行振动分离, 咖啡豆由于大于筛网 留在了上面, 腐乳便落在了筛下。
分离的附属产品是腐乳, 对该腐乳进行加工处理后, 可制成"植物奶酪"。 奶酪是人们青睐的美味食品。
目前的奶酪因脂肪含量高、过度摄入会诱发很多疾病。近年来, 国际学术 界出现了对反式脂肪酸安全性的质疑。 国外研究证实, 经常摄入占总热量 5% 的氢化油, 即每天摄入 10-15克 (相当于 100克奶油蛋糕或 50克桃酥) 的反 式脂肪酸, 就会对健康产生一定的危害。将会使得心脑血管疾病的发病风险增 大。 此外, 它还可能导致糖尿病、 冠心病等"代谢综合征"。 天然脂肪被人体吸 收后一周就能顺利排出体外, 而反式脂肪酸则需要数周才能被分解代谢。 "反
式脂肪酸在人体内逗留时间越长, 变肥胖的可能性就越大"。 本发明得到的植 物奶酪属于天然脂肪, 脂肪含量低, 中国的腐乳在西方号称 "东方奶酪", 因 在制作过程中添加了食盐, 使得腐乳在食用中不能替代 "奶酪 "的用途, 本发 明的 "植物奶酪"属于淡味无盐食品, 味道鲜美、 浓香醇厚, 是替代 "奶酪" 的绝好佳品。
S1600 , 干燥歩骤: 将分离出的咖啡豆进行智能化的低温微波真空干燥。 干燥得到的咖啡豆,采用通常的方法进行烘焙处理即可得到烘焙的咖啡豆。将 得到烘焙的咖啡豆直接杀菌包装可制成咖啡豆商品, 咖啡豆商品通过研磨加 水、滤材过滤可作为现磨的咖啡饮品。更重要的是将得到烘焙的咖啡豆采用现 代化的萃取技术制作咖啡提取物, 用于制造速溶咖啡或罐装咖啡。
其中,低温微波真空干燥装置采用了智能化的人机界面控制,采用了低温 微波真空干燥原理。该微波真空干燥装置是集微波能应用技术与真空干燥技术 相结合的一种综合性高新技术设备,物料在干燥过程中水分的蒸发温度与大气 压有直接的关系, 大气压力越低, 水的沸点越低, 在一个大气压下水的沸点是 100°C, 当真空度小于 -0.08 兆帕斯卡时, 水的蒸发温度为 30〜40°C。 咖啡 处在真空状态下进行低温下干燥。因低温干燥, 咖啡在干燥过程中营养成分不 会丢失, 有效的保留了咖啡发酵产生的营养和香味。
本发明还可以不使用毛霉菌,而接种其他有益发酵微生物。本发明以使用 有益微生物发酵菌进行发酵。 该微生物只要满足发酵作用而且安全无毒即可, 没有特别限定, 具体可以是毛霉菌、 根菌、 微球菌等。 这 3种微生物都容易得 到, 从操作的容易性来看, 可以优选使用毛霉菌。 根据本发明, 通过选择微生 物的种类、 培养条件, 可以添加期望香味的香味剂, 产生添加香味的效应。
图 3是本发明的第二实施例的咖啡原料的处理方法流程图。 如图 3所示, 咖啡原料的处理方法包括如下歩骤:
S2100 , 杀菌歩骤: 同实施方式一;
S2200 , 制曲发酵歩骤: 无菌咖啡原料与由咖啡粉制作的发酵基进行混合 均质, 然后接种有益微生物发酵菌, 搅拌均匀后进行发酵, 得到曲醅。 发酵温 度控制在 35度左右, 由于咖啡粉会粘结在一起, 所以, 每隔 5小时松曲一次, 可以适用松曲机进行松曲。 发酵时间不小于 24小时, 得到曲醅。
在本实施例为将第一实施例中的豆腐换成咖啡粉作为发酵基。
其中, 发酵基的制作是: 将咖啡豆研磨成咖啡粉, 然后接种有益微生物发 酵菌, 接种的有益微生物发酵菌, 包括米曲霉和其它可用的菌种, 本实施方式 优选米曲霉。米曲霉、咖啡粉与咖啡原料的重量比为 1 : 40-60 : 4000-6000, 优选 1 : 50: 5000。
本发明还公开另外一种配比方案: 米曲霉占咖啡原料的 0.1% , 咖啡粉, 占咖啡原料的 5%。
S2300, 搓醅歩骤: 将曲醅搓成个粒;
洒水歩骤, 均匀分层喷洒调料水 (纯净水, 白酒等); 调料水用量: 滋润 饱和为止, 滋润 2小时。
S2400, 保温歩骤: 控制温度在 45度 -60度之间。
将滋润后的小粒状曲醅装入无菌的保温装置(如筐)例进行保温发酵。发 酵温度控制在 50度左右。 发酵时间控制在 7天左右出醅。 保温装置要设有温 度、 PH值在线监测仪等设备。
S2500, 二次发酵歩骤: 在曲醅中添加辅料后进行发酵; 辅料添加同实施 方式一。
发酵条件控制在 40度之内。 发酵时间不小于 15天。
二次发酵装置(如发酵坛、 罐、 缸等)分别设有检测装置: 温度、 PH值、 糖度、 乙醇、 溶氧、 空气流量、 罐压、 转速、 取料检测、 酸碱调节装置、 在线 检测及在线上传设备。

与实施方式二不同的是:本实施方式不需要添加咖啡粉等发酵基,本实施 方式是直接接种有益微生物发酵菌, 包括毛霉菌、 根菌或者微球菌。
S3300, 二次发酵歩骤: 在曲醅中添加辅料后进行发酵, 辅料同实施方式 发酵条件控制在 40度之内。 发酵时间不小于 15天。
发酵装置(如发酵坛、 罐、 缸等)配有检测装置: 用于检测温度、 PH值、 糖度、 乙醇、 溶氧、 空气流量、 罐压或转速等参数, 以及配有取料检测、 酸碱 调节装置、 在线检测及在线上传装置。
S3400分离歩骤: 同实施方式一二, 分离出咖啡豆与剩余物 (菌丝) , 将 菌丝制成美味的速溶咖啡添加剂。

所述分离装置选用直立式粘稠物振动筛, 可以将咖啡豆筛选分离出来。 所述干燥装置, 为智能化的低温微波真空干燥装置。干燥装置采用了智能 化的人机界面控制,采用了低温微波真空干燥原理。该微波真空干燥装置是集 微波能应用技术与真空干燥技术相结合的一种综合性高新技术设备,物料在干 燥过程中水分的蒸发温度与大气压有直接的关系, 大气压力越低, 水的沸点越 低, 在一个大气压下水的沸点是 100°C, 当真空度小于 -0.08 兆帕斯卡时, 水 的蒸发温度为 30〜40°C。咖啡处在真空状态下进行低温下干燥。 因低温干燥, 咖啡在干燥过程中营养成分不会丢失,有效的保留了咖啡发酵产生的营养和香 味。
