Abstract
The wurpeel process used by the potato industry produces a peel waste of high solids. This material is easily handled and collected, but due to the caustic used for peel release it has high residual alkalinity. This waste when acidified to neutralize the excess alkali yields a useful feedstuff for cattle. A method for neutralization of the excess alkali by lactic acid fermentation is described.
