相比木质砧板,塑料砧板由于重量轻、易清洗而被越来越多的人所青睐。不过,美国威斯康星大学近日一项研究表明,塑料砧板比木质砧板细菌更多。研究职员发现,包含沙门氏菌在内的细菌很难在木质砧板上存活过夜,但换作是塑料砧板,这些细菌则能存活下来并滋生旺盛。与塑料材质相比,木质砧板有厚度大、韧性强、牢固,更不易出现严重凹陷、更难隐匿细菌等优点,比较适合切肉或坚挺类食物。塑料砧板
Compared to wood cutting board, plastic cutting board due to light weight, easy to clean and more and more people are favored. However, a recent study by the University of Wisconsin showed that plastic cutting boards have more bacteria than wooden cutting boards. Researchers found that bacteria, including Salmonella, had a hard time surviving a wooden chopping board overnight, but instead switched to a plastic chopping block, the bacteria survived and thrived. Compared with plastic material, wooden chopping board has thick, strong toughness, less prone to serious depression, more difficult to conceal bacteria, etc., more suitable for cutting meat or firm food.
