The Scoville Scale 

for

hot peppers

origin

 

"Physiological tests are tabooed in some quarters, yet when the tongue is sensitive to less than a millionth of a grain, it certainly has an advantage."

Wilbur Scoville, 1912

In 1912, Wilbur L. Scoville, a pharmacist, devised the first modern technique for measuring a pepper’s bite. The measure is still used to this day by spice companies and sauce manufacturers everywhere. In fact, if all known peppers were measured using this technique, their scale of pungency would range from 0 Scoville units, for the bell pepper, to over a million units, for the Bhut Jolokia Ghost Pepper.

When hot peppers are consumed, capsaicinoids bind with pain receptors in the mouth and throat that are responsible for sensing heat. Once activated by the capsaicinoids, these receptors send a message to the brain that the person has consumed something hot. The brain responds to the burning sensation by raising the heart rate, increasing perspiration and release of endorphins.

After many experiments, Scoville concluded that no scientific measurement was sensitive enough to offer readings with any degree of precision. He found that the tongue was capable of detecting capsaicin (the chemical in hot peppers that is responsible for their heat) dissolved in a solution a million times its volume; no laboratory test could detect such a low concentration. 

One problem with Scoville’s test is that no two tongues ever agreed, so the panelists’ estimates had to be averaged. Another problem was that the number of tests a panelist could do in a day was limited. Because the tongue would temporarily get used to a given level of pungency, it had to be given rest to cool down before resuming the task. In an eight hour period, no more than 6 samples could be run through the panel. The machine has now replaced the human testing panel, and thirty samples can now be tested within 8 hours without concern for objective accuracy. 

The American Spice Trade Association, an industry trade group, is a strong proponent of the machine. And the HPLC machine (High Pressure Liquid Chromatograph) measurements are expressed in ASTA units, (the acronym of the trade group). But Scoville’s name has become so well established that the association has had about as much success in making people adopt the scale as the US has in adopting the metric system. The companies that do employ the modern instrument use a conversion scale to express ASTA units in familiar Scoville units. Such is Scoville’s legacy.
