Description

Technical Field

[0002] Fruits and vegetables are essential to people's lives. However, some fruits and vegetables currently on the market are often grown with high levels of pesticides, or are harvested close to the time of application. This leaves large amounts of pesticide residue on their surfaces, which are difficult to wash off with water. Long-term consumption of these pesticide-contaminated fruits and vegetables can lead to the accumulation of harmful substances in the body, affecting health and, in severe cases, causing food poisoning and endangering life. While washing fruits and vegetables with salt water can remove some parasites attached to their surfaces, it is less effective in removing pesticides from their surfaces. Summary of the Invention

[0159] In summary, the ternary synergistic system of nanosilver, baking soda, and citric acid produces a combined effect of physical adsorption, chemical decomposition, and biocidal disinfection. Testing has shown that the removal rate of organophosphorus pesticides has increased to over 92%, and the kill rate of common foodborne pathogens such as E. coli has reached the standard of 99.9%. Furthermore, the innovative dual-process design enables the product to meet the differentiated needs of both powders (fast dissolution) and tablets (precise dosage). Users can choose the cleaning method based on the type of fruit and vegetable. The acid-base reaction between baking soda and citric acid creates effervescence. The bubbles, when they burst, create a tiny physical impact force that scours cracks and wrinkles on the surface of fruits and vegetables, helping to remove pesticide residues, dust, and microorganisms adhering to the surface. The movement of the bubbles ensures that the detergent covers the surface of fruits and vegetables more evenly, reducing blind spots. The turbulence generated by the effervescence accelerates the dispersion of the nanosilver / copper / zinc particles, ensuring a more even contact with the surface of fruits and vegetables, enhancing the killing effect of pathogens such as E. coli and improving the cleaning effect of fruits and vegetables.
