Ethylene removal is crucial for fruits and vegetables preservation because even a very low concentration (<0.1ppm) can induce ripening during storage and transportation. Ag+ exchanged ZSM-5 zeolites were investigated as adsorbents for the efficient removal of ethylene. Two ZSM-5 materials (Si/Al ratios of 15 and 40), with different amounts of Ag (up to 6 % by weight) and two compensating cations, Na+ and H+, we...


Ethylene removal with metals-based zeolites for climacteric fruits preservation

Ferreira, R.; Lopes, H.; Fernandes, A.; Lourenço, João P.; Silva, J. M.; João, I. M.; Ribeiro, Filipa

Nowadays, there is a high importance of consuming fresh fruits and vegetables (F&V) in a well-balanced diet. One main issue concerning fruit preservation is ethylene molecule, a natural plant hormone that is responsible for fruits ripening and senescence. Thus, its removal from transportation and cold storage chambers is essential for industrial companies to prevent deterioration or spoilage of F&V and extend t...
