Milk protein analysis
After a short description of bovine milk proteins, the various methods of current or potential use for detecting and determining them in dairy products are reviewed. This includes, first, the determination of total protein from nitrogen analysis, dye-binding capacity, infra-red spectrometry and amino acid analysis. The methods that allow determination of sorne milk protein fractions of interest...
متن کاملThe Jean Dumas Method
Jean Dumas (Fig. 1) published his combustion method in Paris back in 1848. This makes the method considerably older than Kjeldahl digestion. While researching the composition of natural oils, Dumas tried combusting his samples, initially to analyse the carbon and hydrogen contained therein. Combustion therefore makes it possible to analyse multiple parameters, while Kjeldahl digestion is only s...
متن کاملMilk Adulteration with Melamine - Screening, Testing and Real-Time Detection
Melamine – Screening, Testing and Real-Time Detection The adulteration of protein-based food products with melamine is now a well-known issue. Five years ago, the increasing number of renal failures in dogs and cats alerted the authorities to a problem in the pet food supply chain. We now know this was due to the mixture of melamine and cyanuric acid found inside pet food1. These chemicals were...
متن کاملDetermination of total protein in human milk: comparison of methods.
We evaluated four spectrophotometric methods for suitability in determining total protein in human milk samples. Results were compared with those by an established method for the determination of total nitrogen (micro-Kjeldahl). Values for total protein by all four methods significantly correlated with micro-Kjeldahl. For the biuret assay, Lowry-Peterson assay, Bio-Rad Coomassie Blue assay, and...
متن کاملStudy on the accuracy of milk amyloid A test and other diagnostic methods for identification of milk quality
Bulk tank somatic cell count (BTSCC) is a gold standard test for identification of milk quality, but its results are influenced by several interventional factors. Recently, application of acute phase proteins and especially milk amyloid A (MMA) has been considered as accurate parameters for milk quality study. The current research was done to evaluate the accuracy of MMA, BTSCC, fat, protein an...
