Effect of Age of Roots on Yield for Canning Purposes, Chemical Composition of Raw Roots, and Quality of Canned Product of Cobre and U.P.R.3 Sweetpotatoes

Abstract

The effect of age of tubers on the yield for canning of whole sweetpotatoes corresponding to U. S. Grade No.l, the chemical composition of the raw roots, and the quality of the canned product were studied for the Cobre and U.P.R.3 varieties of sweetpotatoes. The greatest overall yields and the maximum yields for canning purposes, were obtained in both varieties by harvesting 150 days after planting. It was observed that the age of tubers had no effect on the chemical composition of the raw root, its behavior during processing, or the quality of the canned product.
