Strawberries (Fragaria × ananassa cv. Cadonga) are highly perishable fruits with a storage life, which may be less than a week. In this study, Aloe arborescens gel was used as post‐harvest treatment in order to maintain strawberry quality. Strawberries coated with edible A. arborescens gel were packaged in a polypropylene box and stored. Fruit titratable acidity, pH, soluble solid content, ascorbic acid, total phenols, total flavonoids, total anthocyanins and antioxidant activity evaluated by two different tests (DPPH and ABTS) were measured during 14 days of storage. Significant differences were found (P < 0.05) for the samples treated with A. arborescens compared to the control. During conservation, use of Aloe gel maintained lower values for total soluble solids, a higher concentration of total phenols and ascorbic acid, and a better antioxidant activity when compared to the control. The anthocyanin content remained largely unchanged throughout, in all compared samples.

Abstract

Strawberries (Fragaria × ananassa cv. Cadonga) are highly perishable fruits with a storage life, which may be less than a week. In this study, Aloe arborescens gel was used as post‐harvest treatment in order to maintain strawberry quality. Strawberries coated with edible A. arborescens gel were packaged in a polypropylene box and stored. Fruit titratable acidity, pH, soluble solid content, ascorbic acid, total phenols, total flavonoids, total anthocyanins and antioxidant activity evaluated by two different tests (DPPH and ABTS) were measured during 14 days of storage. Significant differences were found (P < 0.05) for the samples treated with A. arborescens compared to the control. During conservation, use of Aloe gel maintained lower values for total soluble solids, a higher concentration of total phenols and ascorbic acid, and a better antioxidant activity when compared to the control. The anthocyanin content remained largely unchanged throughout, in all compared samples.
