Optimization on cleaning sterilization processing of cherry tomato

To develop the potential of food safety and commercial value focusing on better appearance and taste, longer storage time and higher good fruits rate, Ning Xia cherry tomatoes were used as materials. The multi-slot automatic-transmission vegetable washing machines and hypochlorite disinfection equipment were applied to clean cherry tomatoes, and the ideal cleaning process parameters were determined by cold preservation experiment. The results showed that the maximum capacity for the vegetable washing machine was 15 kg, the ideal cleaning time was 170 s, under these conditions, the cleaning rate was 99.3%. The sterilization with 100 μg/mL hypochlorite solution for 85 s reduced 1.128 log value of bacterial volume on the surface of cherry tomatoes. With 100 μg/mL hypochlorite-sterilization, the good fruits rate was 77% after stored at 10℃ for 18 days. The study provides a reference for washing sterilization process of cherry tomatoes.
