Consumer Evaluation and Quality Measurement of Fresh-Cut Slices of 'Goldrush' , and 'Granny Smith' Apples.

Fresh-cut apple slices are desired as a convenient snack for general consumers and as a component in school lunch programs. Development of fresh-cut products requires reconsiderarion of cultivar selection as well as storage and preparation methods, particularly for products like apples that are stored for a relatively long time before fresh-cut preparation. We compared the eating quality of a new apple cultivar, GoldRush, with Golden Delicious (one of its parents) and Granny Smith (currently used for fresh-cut slices). We also compared a commercial preservative treatment (NatureSeal for Apples) with an in-house treatment (calcium ascorbate and other active ingredients). Apples stored about 6 months were sanitized, cut into wedges without peeling, and served to 120 consumers (ARS staff volunteers who like apples, eat them frequently, and had no knowledge of the treatments). Panelists rated the acceptability of appearance, flavor, and texture. Subsamples were measured for color and firmness. Both NatureSeal and the in-house treatment maintained cut surface L*, a*, b* values similar to values at the time of cutting. NatureSeal was rated slightly better for texture than the in-house treatment; but there was no significant difference in appearance or flavor. GoldRush scored highest for texture. Acceptability of texture was closely related to slope and area of force/deformation curves, but not to maximum force. Granny Smith scored highest for acceptability of appearance. GoldRush and Granny Smith were scored similarly for acceptabilityn of flavor and Golded Delicious scored lower. The results indicate that GoldRush is a promising cultivar for fresh-cut apple solices.
