Israeli scientists pioneer method to prolong produce freshness using sound waves
Researchers at Bar-Ilan University say the method creates a coating of nanoparticles from the chemical compound chitosan, protecting the strawberries with antibacterial properties and extending their shelf life by 15 days
In today's fast-paced and dynamic era, there is a growing desire to preserve and extend the shelf life of fresh products. Fruits and vegetables sitting in the fridge or on the kitchen counter undergo rapid and natural decay from the moment they are harvested in the field until they are eaten.
Ph.D. student Belal Abu Salha has developed an innovative method for coating fruits with edible nanoparticles using sonochemistry - a method involving sound waves.
