A calcium lactate treatment at harvest, growing system and refrigerated modified atmosphere can affect strawberry's 'Camaraosa' postharvest quality?

Abstract

The aim of this work was to evaluate the effect of a calcium lactate treatment on postharvest behaviour, organoleptic and nutritional quality of strawberries (Fragaria x ananassa Duch., cv. Camarosa) grown in different growing systems and stored in refrigerated modified atmosphere. Strawberry grown in perlite and soil in greenhouse and soil in open field was harvested and dipped in a calcium lactate 1% solution. Fruits were packed in modified atmosphere at 1°C and 8°C. At 1, 3 and 7 days of storage postharvest behaviour, organoleptic and nutritional quality was evaluated. Calcium had a positive effect on fruit firmness and no differences were observed between storage temperatures in calcium treated fruits. Organoleptic quality (except visual quality) was better in fruits grown in open field soil, regardless calcium treatment and storage temperature. Nutritional quality was better in untreated fruits and stored at 1°C.
