  • 同义词

  • |acetic fermentation;醋酸发酵;乙酸发酵

  • 专业解析

    醋酸发酵(Acetic Acid Fermentation)是一种特定的微生物发酵过程,指在氧气存在下,乙醇(酒精)被特定的细菌氧化转化为醋酸(乙酸)的生物化学过程。它是生产食用醋(如苹果醋、米醋、葡萄酒醋)的核心工艺,也属于不完全氧化发酵的一种。以下是其详细解释:

    1. 核心原理与微生物作用者:

      • 该过程主要由醋酸菌(Acetic Acid Bacteria, AAB)驱动。这类细菌属于好氧菌,需要氧气才能进行代谢活动。常见的属包括醋杆菌属(Acetobacter)和葡糖杆菌属(Gluconobacter),其中醋杆菌属在醋生产中更为重要 。
      • 醋酸菌含有关键的酶系统,特别是乙醇脱氢酶和乙醛脱氢酶。乙醇首先被氧化成乙醛,乙醛再被迅速氧化成醋酸。总反应式可简化为: $$ C_2H_5OH + O_2 rightarrow CH_3COOH + H_2O $$ (乙醇 + 氧气 → 醋酸 + 水)。
      • 这个过程释放能量,供细菌生长繁殖。与酵母的酒精发酵(厌氧)不同,醋酸发酵严格依赖氧气(好氧)。
    2. 过程特点:

      • 好氧性:充足的氧气供应是醋酸发酵顺利进行的关键。工业生产中常通过通气、搅拌或使用浅盘发酵器(如传统的奥尔良法)来保证氧气溶解 。
      • 底物要求:起始原料通常是含乙醇的液体,如葡萄酒、苹果酒(西打)、麦芽汁、米酒或稀释的食用酒精溶液。这些被称为“醋基”或“酒醪”。
      • 产物特异性:主要终产物是醋酸(乙酸)。但在某些条件下或使用特定菌株,也可能产生少量其他代谢物,如乙醛、乙酸乙酯(赋予醋香气)、葡萄糖酸、酮类等,这些物质共同构成醋的风味特征 。
      • 自限性:高浓度的醋酸和低pH值(通常在2-3之间)会抑制醋酸菌自身的生长。因此,发酵达到一定酸度后会自然停止。通过选择耐酸菌株和控制条件,可以提高最终醋的酸度。
    3. 应用与产物:

      • 食用醋生产:这是醋酸发酵最主要的应用。根据使用的酒醪不同,可生产出风味各异的醋,如葡萄醋、苹果醋、米醋、麦芽醋、白醋等 。
      • 食品保藏:醋的酸性环境能抑制许多腐败菌和病原菌的生长,因此醋酸发酵(或直接使用醋)是重要的食品保藏方法(如腌制蔬菜)。
      • 风味剂:醋是广泛使用的调味品,为菜肴提供酸味和复杂风味。
      • 其他工业应用:醋酸是重要的化工原料,虽然大规模工业生产主要通过化学合成法(甲醇羰基化),但生物发酵法在某些特定产品或地区仍有应用。
    4. 与酒精发酵的关系: 醋酸发酵通常紧接在酒精发酵之后。酒精发酵(由酵母完成,厌氧过程)将糖类(如葡萄糖、果糖)转化为乙醇和二氧化碳。醋酸发酵则利用这个乙醇作为底物,在好氧条件下将其转化为醋酸。因此,完整的“醋”生产通常包含这两个连续的发酵阶段 。

    醋酸发酵是一种由好氧性醋酸菌驱动的生物氧化过程,核心是将乙醇转化为醋酸。它依赖于氧气,主要应用于各种风味醋的生产,并具有食品保藏和调味的价值。该过程是连接糖类(经酒精发酵)与醋酸的关键生物转化步骤。

    网络扩展资料

    Acetic Acid Fermentation(醋酸发酵) 是微生物将乙醇氧化为乙酸(醋酸)的生物化学过程,主要应用于食醋生产。以下是详细解释:

    1. 定义与核心反应
      该过程由醋酸菌(如Acetobacter属)主导,通过氧化乙醇生成乙酸和水,反应式为:
      $$text{C}_2text{H}_5text{OH} + text{O}_2 rightarrow text{CH}_3text{COOH} + text{H}_2text{O}$$
      此过程需氧气参与,属于好氧发酵。

    2. 发酵类型

      • 好氧性发酵:常见于工业制醋,需通入氧气促进醋酸菌代谢。
      • 厌氧性发酵:如热醋酸梭菌通过EMP途径分解葡萄糖生成乙酸,无需氧气。
    3. 工艺步骤
      食醋生产通常分为两阶段:

      • 酒精发酵:酵母将糖转化为乙醇(如水果、谷物等原料)。
      • 醋酸发酵:乙醇在醋酸菌作用下氧化为乙酸,常采用固态或喷雾回流法。
    4. 应用与产物
      该过程是食醋制造的核心环节,发酵液经提纯可得冰醋酸(化工原料)。若发酵控制不当,葡萄酒等饮品可能因氧化产生不愉悦的醋酸味。

    5. 关键菌种与条件
      主要依赖醋酸菌,其活性受温度、pH值及氧气供应影响。工业中常采用混合菌群以增强发酵效率。

    如需进一步了解具体菌种或生产工艺,可参考相关微生物学或食品工程资料。
