Given that it should be aware of the nutritional benefits, resulting from the consumption of fresh fruits and vegetables consumed raw and/or minimally processed, comparing the efficacy of different individual sanitizing methods against the major food-borne pathogens localized in fresh commodities is of much importance; these products are easily vulnerable to the microbial contamination. In this review, the current propensity of alternative sanitizing methods was introduced, as well as principal elements for deteriorating the cleaning effects were also discussed. Chlorine-based-sanitizers exhibited the microbial reduction of <1.12 log CFU/g on fruits and vegetables. Most of aqueous disinfectants showed ≤3.01 log-redcutions against a variety of microorganisms inoculated on fresh commodities. Similarly, several physical technologies such as hydrostatic pressure and ultraviolet light were effective for reducing surviving bacterial cells could recover and grow rapidly during the whole processing, posing a potential risk of causing food-borne outbreaks associated with the fresh products. The invasion and subsequent localization of the organisms into the inner parts of products, interactions between the microbial cell and food-contacting surfaces, as well as development of biofilms could restrict the antimicrobial activity of the currently used approaches.
鉴于食用新鲜水果和蔬菜所带来的营养益处,应该意识到其生吃和/或轻微加工的好处,因此比较不同个体消毒方法对局部存在于新鲜农产品中的主要食源性病原体的功效非常重要;这些产品很容易受到微生物污染。在这篇综述中,介绍了替代消毒方法的当前倾向,以及讨论了恶化清洁效果的主要因素。氯基消毒剂对水果和蔬菜的微生物减少量<1.12logCFU/g。大多数水基消毒剂对新鲜农产品上接种的各种微生物的减少量≤3.01log。同样,静压和紫外线等几种物理技术对于减少存活细菌细胞是有效的,但在整个加工过程中,细菌细胞会迅速恢复和生长,这可能会导致与新鲜产品相关的食源性疾病爆发。生物体的入侵和随后在产品内部的定位、微生物细胞与食品接触表面之间的相互作用以及生物膜的形成,可能会限制当前使用方法的抗菌活性。
