Food Protein Can Eliminate Pungency and Bitterness of Extra Virgin Olive Oil
Monell Chemical Senses Center

While experimenting in the laboratory, investigators put the extra virgin olive oil into a mayonnaise-like material that would be easier for sensory study participants to assess, rather than drinking unadulterated EVOO from a drinking glass, as is commonly done for EVOO tasting. They discovered that after several hours the oil-mayo mixture was much less pungent and bitter. Even a small amount of egg yolk in the mixture was sufficient to cause this reduction.

Tug-of-War Receptors Controlling Sour Taste Detection in Fruit Flies Sheds Light on Human Taste Biology
Monell Chemical Senses Center

Monell researchers found that flies use two distinct types of gustatory (taste) receptor neurons (GRNs), which are analogous to taste receptor cells in mammals, to discriminate slightly from highly sour foods. One group of GRNs are maximally activated by low acidity, while the other group responds to high acidity.

Better Measures Reveal More COVID-19 Smell Loss
Monell Chemical Senses Center

Studies that used direct measures versus self-report of smell loss could explain the a wide range of estimates - studies using direct measures, about 77% of COVID-19 patients had smell loss versus only 44% with self-report. Direct measures of smell ability involve having patients smell and report on actual odorants, whereas self-report methods include obtaining data through patient questionnaires, interviews, or electronic health records. Direct measures are objective whereas self-report are subjective measures of a person’s experience.
