【科学60秒】芫荽除异味，食物变美味

听力简介：

Here’s a strange tale of two previously unrelated food products. First: chitlins, that delicacy made of fried pig intestines.

In the new research, in the Journal of Agricultural and Food Chemistry, they ___4___ cilantro’s volatile compounds and tested each one for its odor-fighting power. Many seemed to lessen the stink, but one in particular, according to human sniffers, entirely cancels out the odor.[Hiromi Ikeura et al., "Identification of (E,E)-2,4-Undecadienal from Coriander (Coriandrum sativum L.) as a Highly Effective Deodorant Compound against the Offensive Odor of Porcine Large Intestine"]
It’s called (E,E)-2,4-Undecadienal. It works at a very low ___5___—10 parts per billion—so you can’t smell the compound. It’s not masking the chitlin odor, it’s actually neutralizing it. So it’s not just better living through chemistry. It’s better chitlins too
