Abstract

In order to verify the effect of molecular sieve ethylene adsorbent and 1-Methylcyclopropene (1-MCP) on the shelf life of cherry tomato, two kinds of active packaging were comparatively investigated: molecular sieve sachet and 1-MCP pad with 25% Styrene-Ethylene-Butylene-Styrene (SBS) modified LDPE packaging film. LDPE was used as control. The quality properties of samples were measured over 54 days at 25±1°C and 70±2% relative humidity. The ethylene concentration in the package atmosphere and other experimental parameters were measured periodically. The experimental results show that molecular sieve is more effective in decreasing ethylene concentration in the package than 1-MCP treatment. The best result was obtained by using SBS modified LDPE film with molecular sieve sachet which could extended the shelf life of cherry tomatoes.
