Changes in volatiles during cold storage and subsequent shelf-life of 'conference' pears treated with 1-MCP

Popis výsledku v původním jazyce

European pears (Pyrus communis L. 'Conference') were untreated or treated with 5 ?l/L 1-methylcyclopropene (1-MCP) for 24 h at 20oC and then kept at 1oC for 80 days. The 1-MCP concentration was achieved by adding 1 g Smartfresh (Agrofresh Inc.) containing 0.14% 1-MCP as active ingredient into the 180-L free space. Pears were evaluated after 20, 30, 40, 50, 60, 70 and 80 days of storage at 1oC followed by shelf life storage at 20oC and normal oxygen atmosphere for 7 days. Evaluative criteria were firmness, soluble solids concentration (SSC), respiration rate, production of ethylene and production of volatile compounds. 1-MCP treated pears kept at 20oC (shelf life) had statistically significant slower softening than untreated fruits (P LESS-THAN OR EQUALTO0.01). Treated fruits were 0.40 MPa firmer than control fruits after a 7-day shelf life period. The effect of cold and 1-MCP treatment resulted in significant inhibition of ethylene production, respiration rate and retention of flesh f
