The Loh Down On ScienceWhat’s worse than the smell of rotten fish? Eating it!
This is Sandra Tsing Loh with the Loh Down on Science.
Ever get a whiff of fish that’s past its prime? Pee-yoo! How can we be sure the catch of the day is really fresh?The fish we eat are spot-checked for freshness at every stage - from fishing boat to sushi bar. But, proper tests take too long to be practical. So, it typically comes down to the smell test...yikes!
As natural bacteria grow on fish, they release nitrogen-containing chemicals like ammonia. These chemicals produce that unique fish market aroma. To TACKLE this problem, scientists in Taiwan have come up with a FRESH fish test! How does it work?Stick some fish in a bag, connect the bag to the device. The device wafts the putrid chemicals from the air around the fish over a sensor. Within minutes you’ll know precisely what’s in that fish!
It’s fast, accurate and could mean higher freshness standards in the whole seafood industry. No more nights regretting that last piece of sushi!
