Application of Food-Grade Silicon Dioxide in Probiotic Foods: Activity Protection and Stable Carrier Technology

Probiotic foods need to solve the pain points of viable bacteria "easy inactivation during storage and easy to degrade by gastric acid".


Probiotic foods need to solve the pain points of viable bacteria "easy inactivation during storage and easy to degrade by gastric acid". Food-grade silicon dioxide, as a porous carrier material, provides dual protection for probiotics. Its porous structure with a pore size of 3-10nm can encapsulate probiotic cells, form a physical barrier, isolate oxygen and moisture, and extends the shelf life of viable probiotics of probiotics at room temperature from 3 months to more than 12 months.
After entering the human body, the carrier can resist gastric acid erosion: the silanol groups of silicon dioxide react slowly with gastric acid, forming a buffer layer on the surface of the carrier, maintaining the internal pH above 4.0, ensuring that probiotics reach the intestinal tract alive, and the viable bacteria delivery rate is increased to more than 60% (only 20%-30% for traditional preparations). For different probiotic strains (such as Bifidobacterium lactis, Lactobacillus acidophilus), the pore size and surface hydrophobicity can be adjusted to achieve precise matching.
The Company's technological breakthrough lies in customized carriers: the developed special silicon dioxide for probiotics has a porosity of 70% and a viable bacteria loading capacity of up to 10^9 CFU/g, has passed FAMI-QS certification, and has been supplied to enterprises such as By-Health and Jiangzhong Pharmaceutical. It provides "strain adaptation test" service, adjusts carrier parameters according to the acid resistance and oxygen resistance of probiotics, and extends the product shelf life.
