 Total phenolics (TP), vitamin C, antioxidant activity and colour of preserved peppers were evaluated at 4, 25 and 50 ℃ storage during 30-day intervals. Except for 4 ℃, TP decreased during storage at 25 ℃ and 50 ℃, being softer for fortified samples with β-CDs. The protective effect was evident, since 50 ℃ samples containing β-CDs exhibited lower TP loss (19%) than control samples (38%) for 5 months storage. A decrease in the vitamin C content was observed for both samples as time and temperature progressed. In samples stored at 50 ℃ the protective effect of β-CD only was evident at the first month, since fortified samples showed lower vitamin C loss (10%) than control samples. The fortified samples with β-CDs exhibited lowest antioxidant activity loss (40%) during 90-day storage at 50 ℃, than control samples (64%). The colour changes were in line with those observed for total phenolics and at the end of study, the presence of 1% β-CDs delayed the darkening of samples at both (25 and 50 ℃) storage conditions. </jats:p
