Abstract

The method and temperature of storage of a product are the basic agents that make it possible to prolong the post-harvest life of strawberries. In this context, this study aimed to evaluate the use of different packages with the passive modified atmosphere in the post-harvest quality of strawberry (cv. Camarosa). The strawberries were harvested and subsequently transported to the Laboratory of Drying and Post-harvest Storage of Agricultural Products, where they were stored in BOD, at 0ºC, and 90±5% relative air humidity. A completely randomized design was used, in a 3 x 5 factorial scheme (three packages: expanded polystyrene (EPS) packaging + polyvinyl chloride (PVC) film at 0 °C; polyethylene terephthalate (PET) packaging at 0 °C; and without packaging at 0 °C (control) x five analysis: at 0, 2, 4, 6, and 8 days of storage), with four replications per day for each treatment. Averages were compared by Tukey test at 5% probability. The variables, fresh mass loss, pulp firmness, pH, soluble solids (SS), titratable acidity (TA) and SS/TA ratio were analyzed. The tested packages had better results when compared to the control treatment. The use of polyethylene terephthalate (PET) packages at 0ºC had a less fresh mass loss during storage days, lower acidity reduction, and no significant decrease in pulp firmness.

Highlights

Strawberry (Fragaria x ananassa) is admired worldwide, being the species with the highest economic expression among small red fruits
The adaptability of different strawberry cultivars allows their cultivation in different Brazilian states, which directly reflects on yield, quality, storage period, and response to applied post-harvest treatments (Chitarra and Chitarra, 2005)
For the variables, fresh mass loss, pH, soluble solids, and titratable acidity, there was a significant interaction between the types of packaging and storage day

Summary

Introduction

Strawberry (Fragaria x ananassa) is admired worldwide, being the species with the highest economic expression among small red fruits. Firm pulp, conical shape, strawberry is rich in vitamins C, B1, B2, B5, minerals and phenolic compounds, and it is indicated in cases of diet, as 100g of fruits has only 39 calories (Cajamarca et al, 2017; Giampieri et al, 2012). The adaptability of different strawberry cultivars allows their cultivation in different Brazilian states, which directly reflects on yield, quality, storage period, and response to applied post-harvest treatments (Chitarra and Chitarra, 2005). The use of low temperatures is an essential tool for prolonging the post-harvest life of strawberries due to its effect on metabolic reaction rates (Flores Cantillano et al, 2008), interfering with vital processes such as respiration, ripening, loss of mass and pulp firmness (Chitarra and Chitarra, 2005). For prolonged storage, cooling alone is not enough for maintenance and fruit quality, and other techniques need to be employed to extend fruit shelf life (Chen et al, 2016)
