This invention discloses a visual anti-caries
probiotic lozenge and its preparation method, belonging to the field of pediatric oral care technology. The invention uses *
Lactobacillus rhamnosus* SD11 as the core functional strain, employing
spray drying technology for single-layer microcapsule encapsulation, combined with a pH-responsive natural
pigment color development mechanism, and compounded with
xylitol,
calcium carbonate, and
vitamin D3 to produce an
oral lozenge. This product inhibits
cariogenic bacteria by regulating the oral
microecology, achieving caries prevention, and visually indicates
oral health status through
color changes. Simultaneously, the strain can reach the intestines to exert systemic regulatory effects. This invention utilizes
spray drying microencapsulation and dry
granulation processes, resulting in high production efficiency, stable quality, and advantages such as high safety, good compliance, clear
efficacy, and suitability for industrial production. It is suitable for long-term daily use by children aged 2-12 years.
