Abstract : Food additives play important roles in food industry, misusing food additives, such as above the limits or range, and using prohibited additives are often occurred in practice.This affectthe development of food industry in our country as well as consumer's health. However, during daily monitoring, we found that some chemical pollutants in food were not added artificially, but was formed by endogenous substances inside or during food processing. The existing detection methods are not able to distinguish whether pollutant is added artificially or brought by raw materials, and this brings difficulties in supervision. In order to understand that these chemical compounds are naturally occurred in food instead of added artificially and provide scientific basis for food safety supervision, the review studied and discussed background values of food additives, such as benzoic acid, phosphate as well as the prohibited additives such as methanol and borax.

我国对食品添加剂的使用有着严格的要求。《食品安全国家标准食品添加剂使用标准》（GB 2760-2014】[1]是食品监督抽查判定的重要依据之一，实际检测中我们发现食品中有些化学污染物并不是人为添加的，而是天然存在的，这就给结果的判定带来了困惑。目前，我国对食品中内

源性化合物的本底含量研究较少，在缺乏系统性和针对性的调查数据情况下，一些产品标准中将添加剂使用限值规定为“不得检出"，然而食品中检出的添加剂并非都是人为添加的，这就给食品安全监管部门的执法带来不便，易引发消费恐慌，同时也给相关食品企业的经济和声誉带来很
