Synthetic Chemicals Vs Surface Microbe Control
GreenPod Labs Insights: After banana harvest, bananas are washed with chlorine water and synthetic chemicals (anti-microbial) before being packed into 13 Kg boxes for the export supply chain. We heard from our customers that despite using synthetic chemicals they were still facing microbial growth in the destination market. To investigate this further, we wanted to understand the inconsistencies in the banana washing process and the microbial impact on that. We took actual water samples from the banana wash station and tested them for enumeration of microbes in our in-house microbiology lab. In a single farm on average 600 boxes of bananas are packed in a day - we took the water samples at the start during box 1 and at the end, after box 600. The synthetic chemical is added at the start of the process and used for the entire 600 boxes. This helped us compare the two extremes and evaluate where inconsistencies are. The results were fascinating, box 1 had zero cfu after the synthetic chemical wash, but, box 600 had 10^6 cfu per ml of microbes (extremely high). The effectiveness of the synthetic chemical in eradicating the surface microbes diminishes throughout the process. Thus despite using synthetic chemicals bananas are getting microbial spoilage at the destination market. This gives us more confidence to build the product for both delaying ripening and controlling surface microbes for the banana export market.
