Water-saving salad cleaning with ultrasound

Fresh, pre-packaged salads are among the most perishable foods due to their composition of cut plant parts and an often high natural germ load. At worst they can cause diseases or even food poisoning if the cold chain is interrupted on the way to the consumer. The MultiVegiClean project has developed a novel cleaning process that cleans lettuce and vegetables more effectively than before by using ultrasound. This ensures fewer germs in the final product, and also much lower water consumption.
