Shelf-life of fresh-cut pears processed after harvest and storage in controlled atmosphere
The aim of this work was to investigate the effect of different agents on shelf-life of fresh-cut pears Packham’s Triumph variety. Treatments were obtained with pear fruits after harvest and after six months of controlled atmosphere storage. Colour and texture measurements, as well as visual evaluation of untreated and samples treated with different agents, during sixteen days of storage at 4 °C, were carried out. Fresh-cut pear slices were dipped for 2 minutes in water solution of hydrogen peroxide (HP), potassium sorbate (PS), ascorbic acid (AA), calcium ascorbate (CA), sodium hexametaphosphate (SHMP), calcium chloride (CC), and combinations of AA with SHMP (2 % AA + 1 % SHMP, 2 % AA + 2 % SHMP, 3 % AA + 1 % SHMP, 3 % AA + 2 % SHMP) and calcium chloride (2 % AA + 0.2 % CaCl2, 3 % AA + 0.2 % CaCl2). The shelf-life of fresh-cut pears (prepared from pears after harvest) could be prolonged, depending on treatment, on about 12 to 16 days (the best treatment was 2 % AA + 0.2 % CaCl2). Shelf-life of samples, prepared from fruit stored in controlled atmosphere for 6 months was approximately 8 days, except for samples treated with 1 % calcium ascorbate (12 days). Addition of calcium (calcium ascorbate) significantly prevented tissue breakdown of samples during storage at 4 °C. Quality of minimally processed fruits depends on fruit (raw material) quality during prolonged storage.
