Determination of detection and biological effect of formaldehyde exposure in food

通过食物中含有的甲醛经饲料口服，导致小鼠胃肠道中大肠杆菌数量减少，胃肠道黏膜免疫系统受到干扰。由于含甲醛食品在传统的提取检测方法中很可能被低估，且长期暴露于低水平甲醛会对胃肠道免疫力产生不利影响，因此有必要对食品中的甲醛进行进一步的安全性评估。

Oral administration of formaldehyde via chow that were intended to be contained in the food caused reduction of number of E. coli in the gastrointestinal tract of mice and the disturbance the immune system of the gastrointestinal mucosa. Since formaldehyde-containing foods in the conventional extraction method of detection is likely to be underestimated and long term exposure to low level of formaldehyde to adversely affect the gastrointestinal tract immunity, the need for further safety assessment for the formaldehyde in foods has been shown.
