When my mother-in-law came back from Taiwan last week, she brought back some Taro Cake. When I opened the packaging, I saw a piece of technology I haven’t encountered before, the Wondersensor Oxygen Indicator!
Unfortunately as with most Taiwanese products, there was a serious lack of directions. I had no idea whether the “Don’t Eat” is in effect. What was the color code for “Yes you can eat”? A color legend would be nice here to provide guidance to its interpretation.
In case you were mystified by these purple-colored pastry, here’s a cross-section of the contents:
Flaky Taro-flavored soft shell with Mochi inside. Delicious!
I think that the “Don’t Eat” means that you do not eat the indicator.
If there’s too much oxygen inside the packaging, the color will turn blue.
