The Possibilities of Using Ultrasonically Activated Streams to Reduce the Risk of Foodborne Infection from Salad

In this study, we investigated the effects of an ultrasonically activated stream (UAS) on removal microbial contaminants from spinach leaves. The loads samples cleaned with and without UAS were enumerated using cell culture method compared against unwashed day 0 6 after cleaning. cleaning leaf quality also examined through both macroscopic microscopic inspection, as well measurement electrolyte leakage rate. Results showed that load for 2 min was significantly lower than those treated ultrasound. Comparison between 40 s versus indicated a duration allowed sufficient time to disaggregate detach contamination more effectively. case, induction bacteria into viable but non-culturable state does not affect shelf-life test results much it clean. did produce significant surface damage, which can overall quality. These findings highlight potential systems in salad industry improve microbiological shelf life salads.
