Green Sencha Health Benefits
13. Bad Breath
a. In the investigation of green tea extract on bad breath of the study of "The effect of green tea extract on the removal of sulfur-containing oral malodor volatiles in vitro and its potential application in chewing gum" by Zeng QC, Wu AZ, Pika J.[18a], researchers found that Adding 5% baking soda to green tea extract-containing chewing gum was found to buffer saliva pHs to 8.0 during 10 min of chewing. However, severe discoloration was observed and undesirable bitterness was perceived, most likely due to the polymerization of unencapsulated green tea polyphenols. Therefore, encapsulation of green tea extract is recommended for applications at elevated pHs.
b. In the evaluation of the effect of green tea and mouth air of the study of "Effect of green tea on volatile sulfur compounds in mouth air" by Lodhia P, Yaegaki K, Khakbaznejad A, Imai T, Sato T, Tanaka T, Murata T, Kamoda T.[19b], researchers wrote that green tea was very effective in reducing oral malodor temporarily because of its disinfectant and deodorant activities, whereas other foods were not effective.
