Cell-associated bovine immunodeficiency virus (BIV) and cell-free BIV were subjected to increasing temperatures, including pasteurization conditions. To determine the effect of heat treatment on BIV viability, reverse transcriptase activity and infectivity of the heat-treated virus were assessed. BIV was inactivated by heating to 47 degrees C for 30 min and by low- and high-temperature pasteuri...

sodium salt of n-acetyl-dl-tryptophan (at) and octanoic acid (caprylic acid ca) individually and in combination were studied as thermal stabilizer with different concentrations in heat treatment of human albumin solution. hplc protein profiles before pasteurization of albumin showed less than 1% polymer. in free stabilizer albumin solution during pasteurization visible clot was formed. but by u...

materials and methods samples were collected from six different farms and milk factories in iran, and were tested by beta-star and cylinder-plate methods. results among 992 raw milk samples, 236 positive samples, 9 suspected and 747 negative samples in respond to beta-star test and among 236 samples, which had positive responses to beta-star test, 28 positive, 0 suspected and 208 negative resul...

Colostrum and milk fed to dairy calves become remarkably high in total bacteria count (cfu/ml) during summer weather unless they are refrigerated and/or fed very soon after collection. A paper that we published in 2012 examines the seasonal effect of milk kept at ambient temperature following pasteurization; the bacteria count rises to very high levels again in just a few hours during typical s...

Eggs are possible hosts and transporters of pathogenic microbes such as Salmonella enteritidis as it contains higher nutrition. Heat pasteurization is the suitable method for reducing these pathogens, but the important functional properties of the eggs are exaggerated because of the protein denaturation. Based to various laboratory experiments, Finite Difference Time Domain (FDTD) and Finite El...
