  1. 1. Determination of bio-accessible amounts of metal trace elements in baby food using In vitro artificial digestion

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Marcus Andersson; [2022]
    Keywords : Food; toxic metals; children; bio-accumulation; artificial digestion; ICP-MS;

    Abstract : Prefabricated baby food is under strict EU legislation by Commission Regulation (EC) 1881/2006 Setting maximum levels for certain contaminants in foodstuffs regarding the maximum allowed content of potentially harmful elements. For potentially toxic trace elements the regulated maximum content is regulated for lead, cadmium, mercury, inorganic tin, inorganic arsenic, cesium, copper and manganese. READ MORE
