对啊，不知道啥是植物色素？ Purple corn loses its color after cooking because the pigment responsible for its purple hue, called anthocyanin, is sensitive to heat and tends to degrade during the cooking process, often leaching out into the cooking water, resulting in a less vibrant purple color on the corn kernels; essentially, the heat breaks down the anthocyanin molecules.

去home depot买点氨水，大概两三块钱，测一下，如果确认是硫酸铜，那可以给记者爆料了都，很恶劣。
我当年用这个办法给我家里人验证说我们没有吃到蓝色染料。
有没有可能淀粉和碘的化学反应，变蓝了？
真的是这样，我也买到过吃完牙都蓝了

真的，活久见。。。美国也有这样的了？？？ 我在中国真见过染色的花椒什么的，但美国从来没遇到过。
