- At Ore-Ida, the Boise affiliate of H.J. Heinz Co., they peela
- lotta potatoes -- about 6,000 tons a day. Traditional recipe:
- steam 900 lbs. of potatoes in a vast vat; release the steam so
- the skins drop off. Preparation time: two minutes. Drawbacks:
- you lose nearly a tenth of a tater with the skin and generate a
- dun-colored, viscous by-product, used as cattle feed.
-
- Now there's a no-muss new method: using a $3 million
- combination of industrial-grade lasers, you can vaporize the
- skin right off the potatoes as they fly through a funnel at the
- rate of 1,800 a minute. This laser surgery for spuds, designed
- by researchers at Battelle Memorial Institute in Columbus, works
- even better on tomatoes, a key commodity for catsup-making
- Heinz, which owns the still experimental technology. Ore-Ida
- won't update its recipe for peeling potatoes until the price of
- lasers, already declining, drops even more. Any commercial use
- of laser peeling is at least three to five years away. But even
- this state-of-the-art technology has got to be viewed as a
- godsend to the soldier facing KP.
