Characterization of ‘Honeycrisp’ and ‘McIntosh’ Apple Juice Quality in Relation to Delayed Cooling Treatments

摘要

In order to examine the influence of delayed cooling on juice quality, seven and three days of delayed cooling were applied to ‘Honeycrisp’ and ‘McIntosh’ apples, respectively. After the delayed cooling treatment, apples were stored in refrigerated air (RA) and in three different controlled atmospheres (CA) for six months. Titratable acidity (TA) de-creased over the storage period due to the delayed cooling treatment for both ‘Honeycrisp’ and ‘McIntosh’ apples. Lower TA was detected in RA-stored apples compared to CA-stored fruit. In addition, the lowest TA of the juice samples was detected when ‘McIntosh’ apples were stored in RA with no delayed cooling treatment.
