Lactobacillus brevis NB10 isolated from human saliva, showed in vitro effect on inhibiting the growth and the biofilm formation of Streptococcus mutans - a major pathogen that initiates dental plaque and caries. Formulation of chewing gum containing L. brevis NB10 is the next step in using this probiotic for the prevention of dental diseases related to S. mutans. Methods: Cryoprotectants such as sorbitol, mannitol, xylitol, lactose, maltodextrin, skim milk and potassium ascorbate were selected to formulate the freeze-dried powder containing L. brevis NB10. Next, the freeze-dried powder of L. brevis NB10 was used to make chewing gum by direct compression method using HIG-04 gum base (Heath in Gum ®). Other ingredients such as xylitol, strawberry flavor powder, glycerin, aerosil, talc, and magnesium stearate were selected to formulate chewing gum with suitable chewing feel, taste, and flavor. Results: The freeze-dried powder showing the highest bacterial survival rate (75.5 ± 7.6%) consists of 6% maltodextrin, 6% skim milk, and 0.25% potassium ascorbate. The optimal formula of chewing gum tablet consists of 10% L. brevis NB10 freeze-dried powder, 10% xylitol, 2% strawberry powder, 1.5% glycerol, 1.5% magnesium stearate, 1.5% talc and 2.5% aerosil. The bacterial survival rate after tablet compression is 34.34 ± 0.55 %. The product is stable for at least 3 months at 5 ºC ± 3 ºC. Conclusion: This study was successful in formulating chewing gum containing at least 10 7 CFU/tablet of L. brevis NB10.
