Abstract: Soluble solids concentration (SSC) is a major quality attribute for apple fruit that influences consumer purchases. Prediction of fruit quality at harvest and after storage has become a significant focus for the postharvest area. The objectives of this study were to evaluate the relationship between fruit dry matter concentration (DMC) with SSC at harvest and after storage for ‘McIntosh’, ‘Red Delicious’ and ‘Fuji’ apples and to develop models based on near-infrared… Show more Abstract: Soluble solids concentration (SSC) is a major quality attribute for apple fruit that influences consumer purchases. Prediction of fruit quality at harvest and after storage has become a significant focus for the postharvest area. The objectives of this study were to evaluate the relationship between fruit dry matter concentration (DMC) with SSC at harvest and after storage for ‘McIntosh’, ‘Red Delicious’ and ‘Fuji’ apples and to develop models based on near-infrared (NIR) spectroscopy (729 – 975 nm) to predict SSC and DMC. Fruit were harvested multiple times at one week intervals. Results have shown that fruit DMC and SSC at harvest were closely related and the relationship was improved during maturation and storage. Partial least square regression (PLS) was used to build calibration models for prediction of SSC and DMC. Coefficient of determination (R 2 ) values for calibration models ranged from 0.77 to 0.85 for SSC, and from 0.75 to 0.85 for DMC. Root mean square error (RMSE) of calibration models ranged from 0.44 to 0.62% for SSC, and from 4.25 to 4.92 g kg -1 for DMC. A strong linear relationship was found between DMC and SSC and NIR spectroscopy shows great potential for use as a non-destructive prediction method to determine SSC and DMC.

Prediction of fruit quality at harvest and after storage has become a significant focus for postharvest area. In recent year, fruit dry matter concentration (DMC) has been found to have great potential to predict fruit quality attributes, especially SSC. The objectives of this study are to evaluate the relationship between fruit DMC at harvest with fruit SSC and flesh firmness at harvest and after storage; and also to investigate the effect of 1-methylcyclopropene (1-MCP) treatment on these relationships. Fruit from ‘Honeycrisp’,‘Mclntosh’, ‘Red Deliciou’, ‘Golden Delicious’, ‘Jonagold’, ‘Fuji’ and ‘NY2’ cultivars were harvested twice with one week interval from trees at the Cornell University orchards at Ithaca and Lansing, NY. Fruit DMC and SSC at harvest were closely related and more so at harvest 2 than harvest 1. Relationships slightly improved during air and controlled atmosphere (CA) storage, though not affected by increasing storage periods. No effect of 1-MCP and poststorage period was detected. Relationships between fruit DMC and flesh firmness were cultivar-dependent, and highly influenced by the moisture content of fruit.
