Fenugreek leaves. Bitterness values that vary among populations have been measured by a human dilution-threshold method.

Reading the bitterness
Dried leaf extracts from 30 populations of 10 species, grown under the same conditions, were evaluated by 10 adults using the WHO dilution threshold method. Among these, the bitter values of T. foenum-graecum's TFG1, TFG2, and TFG3 were 9.43, 10.32, and 9.64 ×10³ units/g, respectively, with TFG2 the highest among all samples. This is a value based on the dilution threshold of the extract, not the bitterness intensity felt as a mouthful of food.
In the analysis of the same material, the correlation between diosgenin content and bitter value in fenugreek leaves was r=0.92. However, this correlation is based on pooled data from 30 populations of 10 species, and it is not a dose-response experiment that directly establishes diosgenin as the causal substance of bitterness.
Sources for this overview
Checked for this overview: Matched to the dried leaf extracts from 30 populations of 10 species grown under the same conditions, the WHO dilution threshold method with 10 adults, and the bitter values of the three T. foenum-graecum populations. / Matched to the r=0.92 correlation, the pooled data from 30 populations of 10 species, and the limitation that it does not establish causation.
