Effect chewing tapioca pearls in the bubble tea drinks on the salivary α-amylase and phosphate level

Bubble tea drinks contained tapioca pearls, that can stimulate mastication. Chewing pearls may saliva production. Increased salivary secretion is thought to be correlated with an increase in inorganic components and α-amylase (SAA). This study aimed evaluate the effect of bubble on SAA phosphate (PO 4 3- ) levels. Subjects were 15 people a total sample 60. Each subject drank pearl for 3 days first week as intervention group. In second subjects without control Saliva samples taken day 1 before treatment after treatment. was collected morning 09:00 am–12:00 pm minute. levels measured using ELISA kit Optical Density (OD) at 405 nm. Phosphate semi-quantitative test kit. Data analyzed ANOVA, Kruskal Wallis, t-test, Pearson (p < 0.05). The results ANOVA Kruskall-Wallis showed there significant difference consumption 0.005) increased significantly drinking higher than bubble. Comparison between not different > Correlation level 0.05) r moderate category. It concluded bubbles could (SAA) also improve quality through buffer mechanism.
