This study evaluated the effects of polyethylene terephthalate (PET) treatments with different numbers of holes on the
preservation of strawberry tree (Arbutus unedo L.) fruit. For this purpose, PET treatments with different holes were
evaluated for respiration rate, weight loss, color (L*, a*, and b*) changes, soluble solids content (SSC), titratable acidity
(TA), vitamin C, total phenolics, total flavonoids, antioxidant activity (DPPH and FRAP), and individual phenolics. Analysis
has shown that weight loss increases as storage time increases. It has been determined that PET 2 treatment is more effective
than PET 1 in terms of weight loss and respiratory rate. During the storage, TA and SSC were lower in PET 2, while
the vitamin C content was higher. It was determined that PET treatments had different effects on color parameters, total
phenolics, and total flavonoids. Particularly in the PET 2, total flavonoids and DPPH activity was significantly higher
during storage. It has been determined that catechin is the major content in strawberry tree fruit, which increases in both
treatments with the progress of cold storage. When the 10 individual phenolics examined were evaluated, storage time
and PET treatments had different effects. The significant effect of PET treatments continued only for epicatechin and
protocatechuic acid during storage. As a result, it has been shown that PET 2 treatment is more effective in preserving
fruit quality and nutritional values.
