做豆浆会有很多泡沫怎么办

Answer 1

有泡沫也没关系，煮好后豆浆倒出滤渣就不会有泡沫，做法如下：
准备材料：黄豆、清水、冰糖。
一、首先黄都要提前泡一个晚上。

二、泡好的黄豆清洗干净挑出杂物。

三、把泡好的黄豆倒入豆浆机内。

五、然后启动豆浆机的豆浆功能。

六、将煮好的豆浆倒出滤渣。

七、最后加入适量的冰糖拌至溶化即可。

Answer 2

用小火煮沸几分钟，泡沫就会消失。
大豆等许多豆科植物中含有“皂素”，易起泡。自制豆浆快煮开时有大量泡沫，就是因为黄豆中含有皂素的原因。该成份有毒，但不耐热。只要用小火煮沸几分钟，泡沫就会消失。等到泡沫消失才可以安全饮用，此时皂素已被破坏。

豆类毒素来源
有毒动植物食品中毒的食物中毒中比较严重的类型，而豆类中毒素中毒又是有毒动植物食物中毒中最主要类型。豆类放入毒素有植物红细胞凝集素、胰蛋白酶抑制剂、皂素苷、植酸、巢菜碱苷、甲状腺毒素等。不同豆类中毒素的种类和含量均有较大差异，如大豆中主要含有胰蛋白酶抑制物、植物红细胞凝集素、皂素苷；菜豆中主要含有皂素苷、植物红细胞凝集素、胰蛋白酶抑制剂、亚硝酸盐等；蚕豆中则含有巢菜碱苷。
