  • Tastands may uncover tastes and/or off-tastes that were present in the eatable before the addition of the tastand.
  • a tastand will not introduce any substantial taste and/or off-taste of its own. This property differentiates tastands from masking materials. For example to determine if a tastand is a bitter blocker it could be added to a solution of a bitter material such as KCl. If the material is a tastand it will block or substantially reduce the undesirable taste of KCl before it imparts any significant taste of its own. It is understood that a tastand may have the ability to block one undesirable taste more effectively than another undesirable taste.
  • Some tastands may block only one undesirable taste effectively.
  • a given tastand may, for example, block the perception of bitter at a level of 10-20 ppm but require 1000-10,000 ppm in order to effectively block another undesirable taste and/or tastes or it may not block the perception of another undesirable taste or tastes at any concentration. This relative effectiveness or inability to block certain tastes at all will vary from tastand to tastand and/or with concentration of the same tastand.

  • Potassium 2,4-dihydroxybenzoate is also a tastand for the metallic taste associated with saccharin. If 25 to 50 milligrams of potassium 2,4-dihydroxybenzoate is added to a can of soda sweetened with saccharin (69 to 138 ppm of potassium 2,4-dihydroxybenzoate relative to the soda) the metallic taste is substantially reduced or eliminated allowing other flavors in the soda to come through. In the above examples (25-138 ppm) potassium 2,4- dihydroxybenzoate is a tastand because of its ability to block bitter taste at concentrations where it by itself is substantially tasteless.
  • Potassium 2,4-dihydroxybenzoate is sweet only at significantly higher concentrations.

  • one of our teachings is that the tastand can be effective at a low tastand concentration when compared. to the eatable with the undesirable taste.
  • This distinction is not a minor teaching as in practical terms it would be impossible to add more of the debittering material than the bitter materials. If the Tamura paper's lower level of proposed use for taurine (0.5 equivalents of taurine) is added to a one percent (1%) KCl solution, the resultant solution has a pronounced off-taste which was not present when only 0.03 equivalents (0.5% by weight relative to the KCl) was used.

This "moving" of the controls will occur because the blockers are consumed before the eatables that do not contain the blockers. (If an eatable that was found to be bitter in a previously conducted taste test were presented to the panelist at or near the end of the tasting that contained a tastand, the typical result would be that the previously bitter food is no longer nearly as bitter.) In some tests conducted in a randomized manner, pure KCl foods, for example, which were earlier determined to be very bad, bitter and metallic, during the first round of testing, were then determined to be almost as good tasting as NaCl foods when tasted at or near the end of the tasting.
