Potato Crisps may Hold the Solution to World Water Problems

Extracting water from potatoes before making crisps may be a good way to improve water supplies.

Food giant PepsiCo, which owns the crisp manufacturer Walkers, is developing a new technology to extract water from potatoes, reports the Telegraph.

Potatoes to Reduce Heart Risk?

The company is developing a process to capture water released from the potatoes as they are cooked into crisps before using it in the manufacturing process.

The firm hopes by using the extracted potato water, it will eventually be able to unplug all four of its UK crisp manufacturing sites from the mains water supplies.

The water will initially be used in the manufacturing process to clean, peel and slice potatoes when they are brought in, but PepsiCo said that it hopes to also provide tap and drinking water using the system in its factories.

The company even hopes that if it can produce enough excess water from potatoes it may be able to add to water supplies for local communities near their factories.

Martyn Seal, European sustainability director for PepsiCo, said, "About 75 percent of a potato is water. So as there are a lot of natural resources in a potato, we felt we should be tapping into and reusing."

Couch Potatoes Twice At Risk of Catching Colds: Study
Couch potatoes are nearly twice as likely to catch a cold, and a third likelier to suffer bad symptoms of a cold, compared with counterparts who keep fit, American researchers reported.

"When we cook those potato slices while making crisps, the water normally escapes through chimneys in the roofs of our factories," Seal said.

"We are doing some work to capture the water that goes out of those chimneys, treat it and then reuse it in the factory for the washing, peeling and slicing processes," he added.

GM Potato Developed By Indian Scientists With 60% Additional Protein
A team of Indian scientists has grown for the first time, a genetically modified spud called 'protato' that makes up to 60 per cent more protein per gram than ordinary potatoes.

"We think this technology we are working on can capture enough water to allow us to take our factories of the mains supplies," Seal said.
