Objective To explore a preparation method for low-cariogenic soft candy by adopting a dual-intervention strategy combining sugar replacement and dental plaque biofilm regulation. Methods Various gelatinous candies were prepared by substituting xylitol for partial maltose and incorporating food additives including arginine and dextranase. Texture profile analysis was employed to characterize the effects of functional components on candy texture. Dextran decomposition experiments assessed samples’ capacity to degrade dental plaque matrix, while Streptococcus mutans antibacterial tests evaluated the anti-cariogenic efficacy. Results Partial substitution of maltose with xylitol effectively reduced candy viscosity. Food-grade β-dextranase retained its dextran-degrading capability at 75 ℃. Food-grade L-arginine was identified as the primary growth-inhibiting factor against Streptococcus mutans. Compared to sucrose-induced bacterial growth (set as 100%), the optimal compound candy promoted Streptococcus mutans growth at 50.10% of sucrose’s level and 29.19% of control candy’s level. Conclusion The developed soft candy in this study aids in preventing dental caries, thereby contributing to the creation of children’s food products designed to address oral health issues.
