Scoville scale

Citat:In Scoville's method, an exact weight of dried pepper is dissolved in alcohol to extract the heat components (capsinoids), then diluted in a solution of sugar water.[3][4][5] Increasing concentrations of the extracted capsinoids are given to a panel of five trained tasters, until a majority (at least three) can detect the heat in a dilution.[4][5][6] The heat level is based on this dilution, rated in multiples of 100 SHU.[4]
A weakness of the Scoville Organoleptic Test is its imprecision due to human subjectivity, depending on the taster's palate and their number of mouth heat receptors, which varies greatly among people.[6] Another weakness is sensory fatigue:[6] the palate is quickly desensitised to capsaicins after tasting a few samples within a short time period.[4] Results vary widely, ± 50%, between laboratories.[5]
