The bulletin presents the results of a study on the affect of peeling methods on peeling and trimming losses of white potatoes for the processed potato industry. The researchers used Katahdin, Kennebec, and Russet Burbank potatoes, grown in Maine over two growing seasons (1959-60). Potatoes were grown, harvested, graded (when required) and stored by the Plants and Soils Department under commercial storage conditions. Potatoes were peeled shortly after digging, after four months' storage, and after seven months' storage. Under the conditions of this study, for both series, peel, trim and total losses were significantly greater for the abrasive method used than for the other three methods, at the 1% level. There was no evidence that losses by methods, other than abrasive, were appreciably different except trim losses in the graded composited samples. Evidence in that instance showed steam peeling induced significantly lower losses than either the lye or lye plus steam method.
