A new method developed by researchers has succeeded in extending the shelf life of strawberries. Researchers tested five low-density polyethylene (LDPE) films, each infused with solutions containing combinations of plant-derived essential oils and nanoparticles (AgNPs), which have antimicrobial and antifungal properties, to see how they affected the shelf-life of strawberries when used as packaging.

A combined treatment of irradiation and essential oil vapors could effectively destroy insects, bacteria and mold in stored grains. A team from the Institut national de la recherche scientifique (INRS), led by Professor Monique Lacroix, has demonstrated the effect of this process on insects affecting rice. The study was published in the
Microorganisms and insects are the main enemies of stored grains. Currently, the food industry uses fumigants to destroy them. However, these compounds, which evaporate or decompose into gases into air or water, are threatening human health and the environment. When grain is fumigated, a small amount of gas is absorbed by the grain and released into the atmosphere. For food irradiation, the treatment is physical. If new molecules are produced, they are no different than those produc
