In a first experiment, human subjects used a bipolar scale to rate the irritant sensation elicited by 10 sequentially repeated applications of either 3 ppm capsaicin or 250 mM citric acid on one side of the dorsal surface of the tongue, at 1 min intervals (30 s inter-stimulus interval). Citric acid-evoked irritation significantly increased across trials, consistent with sensitization. With caps...
An in vitro gas production technique was used to screen different organic acids (formic, propionic, lactic, citric, and fumaric acid), organic salts (calcium formate, potassium sorbate, and sodium benzoate), and inorganic phosphoric acid for their ability to modulate microbial fermentation in the digestive tract of piglets.
