Last year, Google came up with very interesting doodles on every other occasions and it seems to be continuing the tradition this year as well. The striking, scientist-looking man featuring on the Google Doodle is Wilbur Scoville and it would have been his 151th birthday today. You may have not known him but he was the inventor Scoville test – a scale that measures how hot chillies are.
Scoville was an American pharmacist who created the scale used to measure the hotness of different kinds of peppers back in 1912. Different kind of peppers have different pungency levels. This depends on the concentration of a chemical compound called capsaicin. The more capsaicin they contain, the higher will be the heat. The Scoville Organoleptic test assesses the amount of capsaicin in hot peppers in Scoville heat units (SHU) as measure of the spice levels.
For instance, bell peppers rank 0 on the Scoville scale while chillies with the highest ranking on the scale exceed one million Scoville units. The range varies from with a rating of zero Scoville heat units (or SHU), to the 16 million that represents pure capsaicin. The Carolina Reaper, is currently one of the hottest peppers in the world scoring 1,569,300 on the Scoville heat-measuring scale.
