Washing Water Disinfection of Sweet Potato

Post-Harvest Spain
In collaboration with Roam Technology, the Spanish Laboratory Agrama evaluated the effectiveness of Huwa-San TR-50 in eliminating bacteria and fungi in the washing water of sweet potato.

The challenge

Vegetables grown in open ground can be contaminated with a variety of different pathogens such as Pseudomonas spp., E. coli, Salmonella, Yersinia and Shigella due to the use of contaminated irrigation water or organic fertilizers. These bacteria can form a serious health threat to the end consumer. Additionally, these vegetables often pass through water in processing facilities to remove soil. The number of pathogens in this washing water can rapidly increase and result in cross contamination of the products.

Our solution

Sweet potato washing tests were carried out with water disinfected with Huwa-San TR-50 in sweet potato handling warehouses. There, two consecutive washing steps were performed and during the first and second step Huwa-San TR-50 was used to disinfect the water.

The results

The treatment of the washing water with Huwa-San TR-50 is effective in reducing the microbial load. Huwa-San TR-50 thus proved a valuable partner for the control of microbial activity in the washing water of sweet potatoes.
