ABSTRACT:
A method is provided for selecting starch-containing vegetables which are subject to low temperature sweetening based on the quality of product to be derived from said vegetables when processed in a manner which can result in undesirable product coloration due to chemical changes of surface sugars on the prepared product, a predetermined minimum level of starch granule crystallinity being established for the vegetable to be processed, above which minimal level an acceptable quality of processed product having an acceptable level of coloration is assured. The method comprises measuring starch granule crystallinity of the vegetable to be processed and selecting for later processing vegetables having a measured starch granule crystallinity above a predetermined minimum level which indicates that the vegetable will resist low temperature sweetening.
