High-performance liquid chromatography (HPLC) is widely employed to determine the caseinomacropeptide (CMP) index and detect milk tampering with rennet whey. Prior to HPLC analysis, CMP is subject to a trichloracetic acid (TCA) isolation causing further soluble proteins in the sample to precipitate. On this basis, we wanted to estimate if rennet whey acidification could adversely affect the HPLC sensitivity to detect this peptide.

A new effective milk-clotting enzyme (BY-1) was produced from Bacillus subtilis PNG27. The analysis of MALDI-TOF-MS/MS showed that it belongs to the peptidase M4 family, and had 521 amino acids. It ha...
Current bovine pregnancy detection methods are not reliable until at least day 28 post artificial insemination (AI). The bovine estrous cycle is approximately 21 days; consequently, producers miss an ...
Levels of essential metals in human breast milk (HBM) have been determined by different analytical techniques, but there is few woks about human whey milk fractions. However, the current trend lies in...
Oxidative stress contributes to cell injury and aggravates several chronic diseases. Dietary antioxidants help the body to fight against free radicals and, therefore, avoid or reduce oxidative stress....
Acidification is a practical way of preserving the bacteriological quality of milk so that it can be fed to calves under free-access conditions. The objectives of this study were to evaluate how milk ...
The aim of this study is to investigate the amino acid kinetics in blood after a bout of strength training and ingestion of different milk protein supplements (native whey, whey protein co...
It is not clear which milk compounds are responsible for the growth stimulation. Through short term intervention studies in prepubertal children, we will test the effects of whey, casein, ...
The purpose of the study is to examine the effects of consuming protein supplement (whey) compared to whole milk immediately after bouts of resistance training on muscular strength and bod...
This study was designed to obtain information about the change in postprandial amino acids in blood over time, after consumption of different dairy products with varying proportions of whe...
The purpose of this study is to determine the safety and efficacy of an infant formula supplemented with galacto-oligosaccharides (GOS), beta-palmitate and acidified milk in improving the ...
The protein components of milk obtained from the whey.
The major protein constituents of milk are CASEINS and whey proteins such as LACTALBUMIN and LACTOGLOBULINS. IMMUNOGLOBULINS occur in high concentrations in COLOSTRUM and in relatively lower concentrations in milk. (Singleton and Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed, p554)
A major protein fraction of milk obtained from the WHEY.
The liquid components of milk that remain after the CASEIN, fat, and fat soluble components have been removed. It is also a byproduct of cheese production.
Allergic reaction to milk (usually cow's milk) or milk products. MILK HYPERSENSITIVITY should be differentiated from LACTOSE INTOLERANCE, an intolerance to milk as a result of congenital deficiency of lactase.
