ABSTRACT

Fresh-cut produce is the fastest growing food category in U.S. supermarkets. Sales trends for fresh-cut salads clearly indicate that consumers will pay for fresh-cut produce, if quality and convenience are perceived to be better than or equal to uncut product. The most important driving force behind fresh-cut product purchases is convenience (Ragaert et al., 2004). Due to commercial difficulties in testing product quality, it is often assumed that “if it looks good, it tastes good.” Unfortunately,

quality of intact vegetables and fruits is often determined almost exclusively on appearance, sometimes to the exclusion of flavor and texture.
