Possible good effect on Lyme disease


A study published in 2015 in the European Journal of Microbiology and Immunology examined the effects of four forms of stevia: three liquid forms derived from alcohol and a powdered form. The researchers found that while the powdered form did not show much, the liquid form worked better than the Lyme disease drug and appeared to kill the bacteria that cause Lyme disease after seven days.


A study of the bacteriostatic effect of stevia extract showed that stevia extract had good bacteriostatic activity against E. coli, Staphylococcus aureus and Bacillus subtilis, significantly more so than potassium sorbate. The inhibitory effect of Stevia rebaudiana extract was stronger under weak acidic conditions, and the inhibitory effect of Stevia rebaudiana extract on E. coli was significantly reduced by UV light. There was no effect of temperature on the antibacterial effect of Stevia rebaudiana extract. Overall, the antibacterial activity of stevia extract is stable and less influenced by environmental factors. If stevia extract is applied to food preservation, it can be adapted to different food processing environments, thus extending the shelf life of food.


As the level of social and economic development continues to rise and people become more aware of healthy eating, there is an increasing tendency to use natural preservative and antibacterial agents in food processing and storage. In this study, the antibacterial effects of stevia extract on E. coli, S. aureus and B. subtilis were investigated using potassium sorbate as a control, and it was found that stevia extract had strong antibacterial activity and good thermal stability. As a natural antibacterial substance, it must have a broad development prospect.


Stevia extract is now becoming a raw material used in all major industries, and it can be used to meet the needs of the industry, and because of its low caloric content and the fact that it is a sweetener, it can be used in many fields, with good efficacy and effect.
