目前我国国家标准对啤酒里甲醛含量的要求是2PPM(毫克每升),而对绿色啤酒的甲醛含量要求是0.2个PPM。但是,甲醛即使不用做加工助剂添加到啤酒当中,啤酒在自然发酵过程中也会出现甲醛,而且含量并不见得比添加了甲醛的要低,它很可能是高于0.2个PPM的,目前我国啤酒甲醛含量整体水平在0.3个PPM,而国际卫生组织(WHO)对饮用水的甲醛限量标准是0.9PPM。
到底超不超标不要说,把具体的含量说出来不就得了,估计如果说出来的话肯定吓大家一跳。下面有某啤酒协会的官员如是说:
Professor Gu was further cited as saying that the limit of natural formaldehyde in beer is 0.2 parts per million (ppm) or 0.2 mg per liter, but the formaldehyde content in Chinese beer can be commonly found at a level of up to 1.2 ppm.
