HPLC methods are described for the determination of furanic compounds (hydroxymethylfurfural and furfural) in enteral formulas prepared with dextrinomaltose and milk proteins, and in model systems enclosing these ingredients. These compounds were extracted in aqueous solution, purified with organic solvents, and separated in a reversed-phase C18 column with water-acetonitrile (95:5 v/v). Averag...

Antibiotics improve health and productive performance of pigs. There is increasing evidence that other dietary ingredients may provide similar, but probably not identical, benefits. A properly prepared immune egg product, spray-dried plasma, or a high level of dietary zinc can provide protection against enteric infection in young pigs. Spray-dried plasma also increases growth rate dramatically,...

The advent of rBGH (recombinant bovine growth hormone) has spurred the establishment of an organic milk industry. The food systems/commodity chain analytical framework cannot fully explain the rise of this new food. An adequate understanding of the consumer’s role in the food system/commodity chain requires more attention to consumption as a form of politics. One way to do this is to look at th...

An organic compound containing 5.86 per cent phosphorus and 11.9 per cent nitrogen was isolated (1) from the tryptic digest of bovine milk casein. Further study (2) suggested that, since serine was the only hydroxyamino acid in the compound, it appeared likely that phosphoric acid was bound to the hydroxy group of this amino acid. A serine phosphoric acid was prepared directly from casein (3) a...

The microbiological profile in raw milk cheeses is typically characterized by a multitude of microbial groups, with interactions among them throughout ripening that are not fully understood to date. Incidence of undesired microorganisms in raw cheesemaking milk, as is the case of either spoilage or even pathogenic ones, is a common trait in Portuguese traditional cheeses. Hence, they will likel...

The object of an experiment was inorganic and organic forms of zinc, copper and manganese applied in mineral mixtures to dairy cows. The experiment was carried out on 90 cows with average milk yield for previous lactation of about 9 500 kg milk. The cows received mineral mixtures containing inorganic or organic forms of zinc, copper and manganese for 6 weeks before calving and during the first ...

One member of each of three pairs of monozygous twin dairy cows was fed freshly cut Glycine javanica and kikuyu-grass pasture ad libitum while the co-twins were fed lucerne hay ad libitum and a concentrate mixture. The mean daily digestible organic matter and digestible crude protein intakes for the cows fed pasture were 7.0 kg and 1.35 kg, and for the cows fed hay and concentrates were 10.2 kg...

an official enquiry prompted by a commercial firm in order to know whether a limited amount of hydrogen peroxide can be used in preservation of milk for 48 hours longer than raw milk under ordinary condition. Under the Public Health Regulation now in force in the U.K. or India hydrogen peroxide has been classed as a nonpermitted preservative in foodstuffs. Although any kmd of preservative in a ...

Methods We investigated 3 groups of patients for identifying the food hypersensitivity. 1. Group 60 patients with symptoms of irritable bowel syndrome (IBS) without a diagnosis of organic gastrointestinal disease. 2. Group 19 patients with atopic dermatitis, polysenzitization to inhalant, not to food allergens. 3. Group 6 infants (3-12 months old) with intestinal symptoms (bloody stool and abdo...
