AI Technical Summary
Current synthetic preservatives used in beverages, such as sodium benzoate and potassium sorbate, have health concerns and flavor issues, and natural preservatives like chitosan lack stability in beverage appearance, necessitating a novel microbial growth inhibitor derived from natural products that maintains commercial value.
The use of six specific compounds (represented by formulae 1 to 6) derived from natural products, which are added to beverages at concentrations between 0.1 to 250 ppm, effectively inhibit microbial growth without affecting the beverage's appearance or flavor, outperforming traditional synthetic preservatives in efficacy.
These compounds significantly inhibit microbial growth in beverages, providing high preservability and stability, even at lower concentrations than synthetic preservatives, without compromising the beverage's original color or taste, thus addressing the limitations of existing natural and synthetic preservatives.
