Lead Content of Foodstuffs
The lead content of a number of foodstuffs, particularly baby fruit juices and milk, is reported. Samples were analyzed in quadruplicate by using an automated Delves cup atomic absorption procedure. A large proportion of the products examined contained significant amounts of lead. Of 256 metal can examined, the contents of 62% contained a lead level of 100 mug/l. or more, 37% contained 200 mug/...
متن کاملA Fluorometric Method for Determining the Riboflavin Content of Foodstuffs
A number of chemical methods have been described for the determination of riboflavin (1-13). These methods are in general limited in use because, when applied to certain products, either they are not specific for riboflavin or all the riboflavin present is not recovered (2). In most cases the authors of papers presenting riboflavin methods have indicated that the methods are of limited applicat...

متن کامل5-Hydroxymethylfurfural content in foodstuffs determined by micellar electrokinetic chromatography.
Micellar electrokinetic chromatography (MEKC) has been applied for the determination of 5-hydroxymethylfurfural in several foodstuffs. A 75mM phosphate buffer solution at pH 8.0 containing 100mM sodium dodecylsulphate was used as background electrolyte (BGE), and the separation was performed by applying +25kV in a 50μm I.D. uncoated fused-silica capillary. Good linearity over the range 2.5-250m...
متن کاملMycotoxin tolerances in foodstuffs.
In most countries general legislation on food (and feed) prohibits the sale of products containing poisonous or harmful substances, which would include relevant mycotoxins as well. So far only aflatoxin has been dealt with specifically in legislation. The aflatoxin control may include all foods (and feeds) but is limited in most countries to certain commodities likely to be heavily contaminated...
