As farms increase in scale it often makes sense for them to become their own processing and packaging facility. Traditional a number of disinfectants or sanitizers have been to wash lettuce but could there be a more environmentally friendlier way?

Previously we have talked about using probiotics to effectively wash our produce and preserve its shelf life but researchers in England are experimenting with hypersonic vibrations and microbubbles in water to wash lettuce. According to lead scientist, Prof. Timothy Leighton, “The sound field also causes the walls of the bubbles to ripple very quickly, turning them into microscopic ‘scrubbing’ machines. The rippling bubble wall causes strong currents to move in the water around the bubble, and sweep the microbes off the leaf.”
