Platinum nanoparticles may keep fruit fresh longer

May 13, 2013 8:16 am | News | Comments

Ripening fruit, vegetables, and flowers release ethylene, which works as a plant hormone. Ethylene accelerates ripening, so other unripened fruit also begins to ripen—fruit and vegetables quickly spoil and flowers wilt. researchers in Japan have now introduced a new catalytic system for the fast and complete degradation of ethylene. This could keep the air in warehouses ethylene-free, keeping perishable products fresh longer.
