在制作蛋糕、面包、新鲜面团或披萨时,有些人会对使用哪种酵母(化学酵母或生物酵母)产生疑问。 这两种酵母都具有使面团发酵的功能,但它们之间的差异会影响菜肴的最终效果,每种酵母都针对特定的食谱。

这是因为化学酵母和生物酵母由不同的物质和元素组成,从而导致发酵过程的不同。 但是这些发酵剂之间有什么区别呢? 请看下文。

化学酵母和生物酵母的区别是什么?

化学酵母,或发酵粉,是最常见的,在超市货架上很容易找到。 它由小苏打组成,当与一些酸混合时,会产生二氧化碳气体,这是一种使面团发酵的元素。 这种类型的酵母在制作面团时就已经开始反应,并在面团放入烤箱烘烤时继续反应。

另一方面,生物酵母由所谓的酵母菌组成,它们是以糖为食并释放二氧化碳和酒精的微小真菌。 这种酵母是冷藏的,在低温下酵母菌失去活性。

在室温下加入面团后,酵母开始作用,以小麦粉和糖中的葡萄糖为食,形成各种产物,如酒精,负责赋予面食风味和口感。 另一种产物是二氧化碳气体,如上所述,负责面食的生长。

值得注意的是,生物酵母中的酵母菌在面团放入烤箱加热时反应较慢并死亡。 这就是为什么含有这种酵母菌的面团在放入烤箱前需要静置生长的原因。

有机酵母分为干酵母和鲜酵母两类,干酵母的保质期更长,水分比鲜酵母少,几乎可以瞬间作用于面团。

第二类生物酵母--鲜酵母--水分较多,在其成分中含有较多的凝集酵母。 与干酵母相比,必须按较大比例使用,例如,每10克干酵母需要使用三倍的鲜酵母。

有机酵母类别之间的另一个区别是,新鲜酵母在使用前或使用后必须保存在冰箱中。

每种面团使用哪种酵母?

化学酵母用于制作蛋糕、饼干、速食面包、搅拌馅饼、松饼和薄煎饼。 生物酵母用于制作面包、粗面团、球形面团、重面团、新鲜面团和自制比萨饼。

可以用有机酵母代替发酵粉吗?

您可以使用化学酵母代替生物酵母吗? 答案是肯定的,但您需要在制备面团时改变每种酵母的用量。 为此,请使用以下等量关系:每15克生物酵母等于5克干酵母。

但是,如果您在制作面包时发现家里只有化学蛋糕酵母,您就要小心了。 因为除了少数例外情况,面包面团可以用这种酵母制作。
