制作方法
1.选择豆种：培育豆芽菜应尽量选用当年生或隔年生、完全成熟的新鲜豆种，同时力求颗粒饱满、色泽鲜艳、不受机械损伤及病虫危害等，并且要贮藏在低温、干燥的环境中，常用的选种方法有筛选、风选、水选和人工选等。
2.育前处理：促进种子发芽，通常采用“启动处理”和“浸种处理”。启动处理的方法是：经过预选后的豆粒，在送进育芽容器之前，一般先倒入60℃的热水中，浸泡1～2分钟，随后用冷水淘洗1～2次，目的是为了调整与豆粒种子发芽时有关的氧化酶系的活性，给休眠状态的种子以温度刺激，有助于豆粒发芽整齐一致。浸种处理的方法是：1千克绿豆或黄豆约需1千克水，豆粒浸种的最适合水温为20～23℃。冬天浸种时，一般用温水浸泡，夏天可以用冷水直接浸种，豆粒浸种时间一般约需8～12小时。
3.育芽温度：黄豆和绿豆的种子都属于喜温、耐热的蔬菜作物种子，其豆种发芽时的最低温度为10℃，最适宜温度为21～27℃，最高温度为28～30℃，不宜超过32℃，育芽中调节温度是采用浇水的办法，比如夏季气温过高，应用冷水普遍浇淋豆芽，但要注意浇透培育容器中心部分的芽菜，使它降低温度，冬天气温低，应用温水浇淋，以提高培育中的豆芽温度，同时要尽量减少冷空气的流通。家庭少量培育豆芽菜，冬天可将培育容器放在炉旁、灶头保温。
4.淋水催芽：育芽时的淋水方法一般有两种：一种淋洒法，要求每次淋水时水量要多，同时应该将整个容器内的豆芽菜普遍淋透，务必使整个容器中各部分芽菜的热度调节均匀，直至流出来的水温与淋入时的水温一致为止。另一种是采用灌水法，将水灌满整个容器，并使水面高出豆芽表面2厘米左右，让容器内的豆芽普遍浸在水中，然后再把水全部放走或倒净。这样重复浇灌1～2次，直至容器中各部分的芽菜温度调节一致为止。
5.适时采收：采收最适合在豆芽菜生长发育至胚茎充分伸长，而真叶将露或始露时为最佳，此时胚茎长约5～6厘米，根长约0.5～1.5厘米，豆瓣呈蛋黄色，胚茎显得乳白晶亮，始露的真叶呈乳黄色，不生侧根。此时，每千克绿豆可产7～8千克绿豆芽，每千克黄豆可产4～5千克黄豆芽。
