Evaluation of Changes in the Composition of Apples During Storage by NIR Spectroscopy

Original language description

As part of the experiment, fruit varieties of Idared, Desert and Rubinola were stored under a normal atmosphere in a cold room at 4 oC; the pieces of fruit counted 25 per variety. The fruit was stored for 90 days; every 10 days, the spectra were measured using near-infrared ("NIR") spectroscopy. The stored fruit was evaluated for the content of titratable acidity, soluble solids, polyphenols and ascorbic acid. The spectra of the pieces of fruit were evaluated using NIR spectroscopy based on developed models of calibration. The calibration models consisted of 188 pieces of fruit of Rubinola, Desert and Idared varieties. The aim of the study was to evaluate changes in the material composition of apples during the period of storage using NIR spectroscopy. For all of the three varieties the content of studied substances changed in a very similar manner during the storing period; the content of ascorbic acid was the only exception in that it increased for Rubinola during the time and gradually reduced for both the Desert and the Idared varieties. Idared and Desert had approximately the same content of ascorbic acid at the beginning of storing (about 45 mg/kg). During the storage period the ascorbic acid content decreased almost identically for both of the varieties to reach a final value of about 30 mg/kg.
