A reversed-phased HPLC method that allows the separation and simultaneous determination of the preservatives benzoic (BA) and sorbic acids (SA), methyl- (MP) and propylparabens (PP) is described. The separations were effected by using an initial mobile phase of methanol-acetate buffer (pH 4.4) (35:65) to elute BA, SA and MP and changing the mobile phase composition to methanol-acetate buffer (p...

Since 1994, Mozambique has made considerable progress in reducing its dependence on imported basic foodstuffs, raising agricultural production while macro-economic conditions have improved impressively. However, the majority of the rural populace continues to be poor, depending principally on semi-subsistence agriculture to survive. While land access is still relatively good, there is little us...

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...

We find that, after taking raw foodstuffs, neither the number of white corpuscles nor the correlation of their percentage has changed. Ordinary unboiled drinking water, mineral water, salt, different green foodstuffs, cereals; nuts, honey, raw eggs, raw meat, raw fish, fresh milk, sour milk, butter ― in other words, foodstuffs in the state in which they exist in nature, belong to the group of t...

Sir, There has been great interest in the transfer of antibiotic resistance markers between clinically important bacteria and bacteria present in foodstuffs. We carried out two small studies where fosfomycin resistance was detected in clinical isolates and isolates from foodstuffs during 1994 and 1995. Fosfomycin is a broad-spectrum antibiotic that has been used extensively in European countrie...
