Abstract
The changes in fresh cut grape quality were evaluated over 14 days storage at 5 °C that harvested by two different methods (1-berry and 4-berries cutting), packaged in polyethylene terephthalate (PET) and polyvinylchloride (PVC) bags. The results showed that 4berries cutting, which packaged in PVC bags showed the lowest weight loss, decay incidence, berry shattering, with the highest acceptability as compared to the other treatments. Total soluble solids (TSS) and TSS/TA were increased during storage in all treatments. The phenolic content in 1-berry cutting increased over the storage time, but its content declined in 4-berries cutting. At almost all of treatments, the flavenoids compositions including catechin, quercetin 3-galactoside and total quercetin decreased significantly at the end of storage. Antioxidant capacity increased up to seven days storage and thereafter decreased at the end of storage. Results showed that fruits packaged in PVC bags had higher total phenolic content, phenolic compositions such as catechin, quercetin 3-galactoside and total quercetin and antioxidant capacity than PET ones.
