我国《食品卫生法》规定:“餐具、茶具和盛放直接入口食品的容器,使用前必须洗净、消毒”。以往多采用高温蒸煮的办法;但此法需要一定的设备,且费时耗能,故中小型饭店、茶馆、饮食店(摊)等常难以做到。当前国内有许多单位在进行化学洗消剂的开发研究,研制既能确保消毒效果而又对人体无害的新型洗消剂,以图取代传统的物理消毒法。现已有近10种产品通过鉴定,进入现场试用阶段。大部分制剂的消毒成份为有效氯。最近我们用生物学试验的方法,对江苏常州市武进合成化工厂研制生产的洗消剂“洁消净”进行了安全性毒理学评价,以初步探索该类洗消剂的毒性作用。半数致死量(LD_(50))和7天喂养试验检测其急性毒性作用,用Ames试验检测其致突变性洁消净以二氯异氰尿酸为主要成份,辅以去污活性剂和稳定剂等制备而成。实验室 China’s “Food Sanitation Law” provides: “Tableware, tea sets and containers for direct import food, must be washed before use, disinfection.” In the past, the use of high-temperature cooking approach; but this method requires a certain amount of equipment, and time-consuming energy consumption, it is often difficult for small and medium hotels, teahouse, restaurants (stalls) and so on. At present, there are many units in the chemical decontamination research and development, both to ensure that disinfection effect and harmless to the human body of new decontamination agent to replace the traditional physical disinfection. Nearly 10 kinds of products have passed the appraisal now, enter the trial stage of the field. The disinfectant for most preparations is available chlorine. Recently, we used a biological test method to evaluate the safety and toxicology of the decontamination agent “Cleansing Gel” developed and produced by Wujin Synthetic Chemical Plant in Changzhou, Jiangsu Province, so as to initially explore the toxic effects of such decontamination agents. Acute toxicity was tested by half lethal dose (LD_ (50)) and 7 days feeding test. Ames test was used to detect the mutagenicity. Diclofenac sodium was taken as the main component and decontaminated active agent and stabilizer Preparation and so on. laboratory
