Effect of Flavored, Carbonated Drinks on Salivary Flow, Salivary Composition, and Taste Perceptions
PepsiCo Global R&D
Summary
To determine the effect of flavored, carbonated drinks on salivary flow rate, saliva composition, and taste perceptions compared with control drinks (water, carbonated water, non-carbonated)
Description
Previous studies have shown that drinking a beverage can stimulate the production of saliva and alter its composition. These effects could impact oral processing and taste perceptions. Various ingredients in beverages such as carbonation may affect saliva and oral processing. The objective of this study is to determine the effect of flavored carbonated beverages on salivary flow rate, saliva composition (pH, mucins, carbonic anhydrase, and total protein), and taste perceptions compared with unflavored and non-carbonated control drinks.
