Mushroom Peptides Made Salt Taste Stronger in Laboratory Tests
Researchers in China tested short protein fragments, called peptides, from the edible beech mushroom.
In laboratory taste tests, three peptides made a salt solution seem saltier to 14 trained assessors.
The strongest, ASHGEGF, raised saltiness ratings by about 71 percent compared with the same amount of salt alone.
The peptides also made the salty taste last longer in the tests.
The work addresses a challenge in reducing sodium: food can lose some of its salty flavor when less salt is used.
But the tests did not show how much sodium could be removed without changing taste, and they did not establish the safety of a future food ingredient.
Computer simulations suggested how the peptides might interact with a protein linked to salt taste, but that explanation has not been confirmed in human taste cells.
Researchers in China identified three peptides from edible beech mushrooms that made salt solutions taste saltier in laboratory tests.
The strongest peptide, ASHGEGF, raised perceived saltiness by 70.59 percent when added to a solution with the same salt concentration as the control.
The study involved 14 trained assessors and also used an electronic tongue to compare the samples.
The findings could help researchers develop seasonings that preserve salty flavor while using less sodium.
The tests did not establish how much sodium could be removed while keeping taste unchanged.
- Who
- Researchers at Gannan Medical University and Shanxi Medical University led the study.
- What
- They tested mushroom-derived peptides that increased the perceived saltiness of salt solutions.
- When
- The article was published on October 10, 2026; the study date is not stated.
- Where
- China; the specific testing location is not stated.
- Why
- The research explored whether an ingredient could make salt taste stronger and help preserve flavor while reducing sodium.
This story does not have two clearly opposing sides.
A 71 percent increase in perceived saltiness doesn't mean 71 percent of the salt could be removed.
Researchers broke down edible beech mushroom proteins and used computational tools to select peptide candidates.
14 trained assessors rated salt solutions with and without the selected peptides.
Researchers used an electronic tongue and computer simulations to examine the mixtures and possible interactions.
