Absorption of Ethylene on Membranes Containing Potassium Permanganate Loaded into Alumina-Nanoparticle-Incorporated Alumina/Carbon Nanofibers
Ethylene is a natural
aging hormone in plants, and controlling
its concentration has long been a subject of research aimed at reducing
wastage during packaging, transport, and storage. We report on packaging
membranes, produced by electrospinning, that act as efficient carriers
for potassium permanganate (PPM), a widely used ethylene oxidant.
PPM salt loaded on membranes composed of alumina nanofibers incorporating
alumina nanoparticles outperform other absorber systems and oxidize
up to 73% of ethylene within 25 min. Membrane absorption of ethylene
generated by avocados was totally quenched in 21 h, and a nearly zero
ethylene concentration was observed for more than 5 days. By comparison,
the control experiments exhibited a concentration of 53% of the initial
value after 21 h and 31% on day 5. A high surface area of the alumina
nanofiber membranes provides high capacity for ethylene absorption
over a long period of time. In combination with other properties,
such as planar form, flexibility, ease of handling, and lightweight,
these membranes are a highly desirable component of packaging materials
engineered to enhance product lifetime
