通常做面包面包会出现发酵不起来或者是发较慢怎么回事:
下面6要点:
1.使用酵母过期或用量不足。
2.搅拌过度或者面团没有搅拌出面筋。
3.糖的用量太高会导致渗透压过高而抑制酵母的活动力。一般面包中糖的用量不要超过面粉的22%。
4.盐的量太多,也抑制了酵母的的活动力。
5.温度过低会导致酵母活性低,酵母喜欢的温度是28~30℃。
6.面团水分太多,太过湿黏。

蛋糕制作过程:
1.将鸡蛋的蛋黄与蛋清分离,蛋黄中加入60克左右的砂糖,4-5勺的牛奶。用打蛋器打散搅匀。(加太多牛奶会很稀,不容易熟。)
2.打蛋器打发蛋清,分次加入白砂糖;打到变成白色大泡泡沫的时候,加10克左右的糖再次打发蛋清;待泡泡变小,糖全部融入蛋清后,第2次加入糖打发蛋清;完全稠了,没有泡泡时,第3次加入糖打到硬性发泡,将蛋清盆倒置,蛋清不掉落,留下就算硬性发泡了。
3.将第二步搅匀的蛋黄糊糊,分三次掺入打发的蛋清中,用打蛋器搅拌均匀,搅拌时间不能太长,不能打出面筋,若打出面筋,将影响蛋糕的发涨效果。电饭煲按下“煮饭”预热10秒左右,锅底有点热就可以倒入少许的食用油,摸匀在锅上的整个地方,以防蛋糕粘锅。
4.倒入搅拌好的蛋糊,蹲几下锅,把里面的气泡震出来。按下“煮饭”3分钟左右会自动跳到“保温”这时打开电饭煲,将蛋糕翻一面。再按下“煮饭”3分钟后就好了!
5.趁热将做好的蛋糕从电饭煲中取出,若不及时取出,再将电饭煲盖上,盖子上的蒸馏水滴下去,会影响蛋糕的效果,蛋糕会瘦身缩小。
这样做de蛋糕可以发起来,很蓬松,你这样做就可以了
蛋糕遇到发不起来的现象,最主要原因就是蛋清没有被充分打发,其次就是蒸好以后急于揭锅。
一、蛋清要充分打发
自制水蒸蛋糕最关键的步骤就是打发蛋清,为了保证蛋清被充分的打发,首先要把蛋黄和蛋清彻底分离干净,蛋清里如果有一丁点蛋黄都会影响打发效果。其次就是打发蛋清的容器和工具都必须保证无水无油,有水或有油也会影响蛋清的打发效果。
掌握好以上两个最关键的要点,接下来就是拼命的打了,很累人,可以两个人轮流换着打。开始打之前可以加少许白醋和一点点玉米淀粉,这样就会比较容易打发了。打到蛋清出现粗泡的时候加入1/4的白糖,打到湿性发泡时再加1/4的白糖,另一半白糖是加在蛋黄里的。
最后打到蛋清能立在筷子上不掉下来,这样才算是完全把蛋清打发了。还有不少朋友做水蒸蛋糕是加泡打粉或自发粉的,其实正宗的水蒸蛋糕是不需要加泡打粉或自发粉的,只要把蛋清完全打发就足够了。如果你非要加泡打粉或自发粉,也可以加入少许。
二、不要急于揭锅
造成蛋糕发不起来的第二个原因就是急于揭锅,因为刚蒸好的水蒸蛋糕突然遇冷就会收缩,在蒸的时候也不要用太大的火,蒸好以后稍微等1~2分钟再揭开锅盖,这样就可以避免水蒸蛋糕收缩了。
三、出锅先倒扣放置
蛋糕出锅后最好是先倒扣着放置,因为此时的水蒸蛋糕并没有完全定型,倒扣放置可以防止它被自身的重量压塌。等水蒸蛋糕稍微冷却下来以后就定型了,此时才可以准备脱模切块,随便你怎么摆弄也不会缩小了。
自制蛋糕时如果能做好以上几点,就绝对不会再出现发不起来的现象了。
