Fight food waste with new 'structured liquid' bottle coating

A new food-safe coating for plastic or glass bottles may provide a solution to food waste, allowing consumers to dispense every last drop of packaged product.

Super-slick coatings have a range of industrial uses, but MIT researchers are targeting their new food-safe LiquiGlide material at a common consumer problem—getting the ketchup out of the bottle. 

MIT mechanical engineers and nanotechnologists have teamed up to solve a common consumer problem that could soon have many processors and packagers upgrading their production lines. The problem: How do you get the ketchup out of the bottle? The solution, according to the researchers, is to first apply “LiquiGlide,” a patent-pending, food-safe substance that coats the inside of plastic or glass bottles to make them super slippery.

Imagine getting all the mayonnaise out of the jar, or every last drop of hot sauce out of the bottle. I see spontaneous Vine endorsements popping up for many innovation-driven food brands. But the technology doesn’t stop at the dinner table. Video demonstrations show the benefits of the coating for dispensing honey, cough syrup, wood glue, and paint. As it says on the LiquiGlide website, “be it the pouring of a ketchup bottle, creating efficiency gains on a power plant condenser or preventing a medical tube from clogging, LiquiGlide coatings are a breakthrough technology for solid-liquid interfaces.”
