Contamination by in packaged produce is a major concern. The purpose of this study was to find natural and affordable sanitizers to reduce contamination in agricultural products. Organic acids, ultraviolet-C (UV-C), and ethanol were analyzed either alone or in combination to assess their ability to reduce population in radish, oriental melon, and carrot samples. In radish samples, 3% malic acid combined with UV-C at a dosage of 144 mj/cm significantly reduced (>4 log CFU/g) the population of (1.44 ± 0.5) compared to the control sample (5.14 ± 0.09). In the case of the melon samples, exposure to UV-C at a dosage of 144 mj/cm combined with 3% lactic acid (2.73 ± 0.75) or 50% ethanol (2.30 ± 0.01) was effective against compared to the control sample (5.10 ± 0.19). In carrot samples, 3% lactic acid combined with 144 mj/cm dosage UV-C reduced population (4.48 ± 0.25) more than in the control sample (5.85 ± 0.08). These results reveal that sanitizers that are effective for one crop are less effective for another crop indicating that effective prevention methods should be customized for each crop to prevent pathogen cross contamination during postharvest washing.
包装农产品中的[具体病原体名称未给出]污染是一个主要问题。本研究的目的是找到天然且经济实惠的消毒剂，以减少农产品中的[具体病原体名称未给出]污染。对有机酸、紫外线-C（UV-C）和乙醇单独或组合进行分析，以评估它们降低萝卜、东方甜瓜和胡萝卜样品中[具体病原体名称未给出]数量的能力。在萝卜样品中，3%的苹果酸与剂量为144 mj/cm²的UV-C联合使用，与对照样品（5.14±0.09）相比，显著降低（>4 log CFU/g）了[具体病原体名称未给出]的数量（1.44±0.5）。在甜瓜样品中，与对照样品（5.10±0.19）相比，暴露于剂量为144 mj/cm²的UV-C并结合3%乳酸（2.73±0.75）或50%乙醇（2.30±0.01）对[具体病原体名称未给出]有效。在胡萝卜样品中，3%乳酸与剂量为144 mj/cm²的UV-C联合使用，使[具体病原体名称未给出]数量（4.48±0.25）比对照样品（5.85±0.08）减少得更多。这些结果表明，对一种作物有效的消毒剂对另一种作物效果较差，这表明应针对每种作物定制有效的预防方法，以防止收获后清洗过程中的病原体交叉污染。
