豆制品中铝残留量超标原因溯源分析OA北大核心CSTPCD

Influencing factors and migration rules of 14 kinds of heavy metals in tableware

中文摘要英文摘要

[目的]分析豆制品中铝残留量超标的原因.[方法]采用现场检查、问卷调查的方式,对豆制品企业含铝食品添加剂的使用情况进行调研;采用GB 5009.182-2017第二法和(103±2)℃烘烤5 h,作为检测豆制品中铝残留量的方法和前处理条件;采用清水浸泡、超声波清洗,验证清洗工艺对于减少豆制品中铝残留量的影响.[结果]豆制品中使用含铝添加剂并无工艺必要性;固体消泡剂、石膏、香辛料和茶粉中铝的残留量远高于大豆,经清洗后的原辅料中铝的残留量有不同程度的下降.[结论]豆制品中铝的残留量超标并非使用含铝的食品添加剂所致;主要原因有大豆原料清洗不彻底,将铝含量很高的泥土和灰尘带入到豆制品中;部分大豆原料的本底值较高,固体消泡剂、石膏、香辛料、茶粉等部分辅料的铝含量高,多种成分和因素叠加,导致铝残留量超标.

[Objective]Analyzing the reasons for excessive residual aluminum in soy products.[Methods]Conduct on-site inspections and questionnaire surveys to investigate the use of food additives containing aluminum in soy product enterprises.The second method of GB 5009.182-2017 and baking at(103±2)℃ for 5 h are used as the method for detecting residual aluminum in soybean products and the pre-treatment conditions,using water immersion and ultrasonic cleaning to verify the effect of the cleaning process on reducing the residual amount of aluminum in soy products.[Results]There is no process necessity to use aluminum-containing additives in soy products,the residual amount of aluminum in solid defoamers,gypsum,spices,and tea powder is much higher than that in soybeans,and the residual amount in the cleaned raw materials decreased in varying degrees.[Conclusion]The excessive residue of aluminum in soy products is not caused by the use of aluminum-containing food additives,the main reason is the soybean without being thoroughly cleaned,thus bringing soil and dust with high aluminum content into soy products.The high background values of some soybean raw materials and the high aluminum content of solid defoamers,gypsum,spices,tea powder and other auxiliary materials lead to excessive residual aluminum content.
