Scientists develop starch-based wash to remove pesticides, extend fruit shelf life

Scientists have developed a starch-based washing solution designed to tackle one of India's persistent food safety concerns: pesticide residues on fresh produce. The innovative treatment removes more than 93 percent of pesticide residues from fruit and vegetable surfaces, addressing growing consumer concerns about chemical contamination in the food supply.

Beyond pesticide removal, the wash also enhances the longevity of perishable produce, maintaining quality during storage for up to 15 days. This dual benefit addresses a critical challenge in India's agricultural sector, where significant post-harvest losses result from rapid spoilage and decay, particularly in warm climates.

Researchers used computer simulations to understand the wash's effectiveness, identifying molecular interactions that allow the starch-based material to bind with and remove pesticide residues. The biodegradable composition ensures the solution poses no environmental or health risks, making it suitable for widespread adoption across the food supply chain.

The development comes at a time when pesticide residue management remains a significant challenge for Indian farmers, retailers, and consumers. The sustainable nature of the wash, combined with its effectiveness and ability to extend shelf life, positions it as a practical solution for improving food safety standards while reducing agricultural waste across the region.
