Lactobacillus strains, common in buttermilk, assist the growth of gold, silver, and gold-silver alloy crystals of submicron dimensions upon exposure to the precursor ions. Several well-defined crystal morphologies are observed. Crystal growth occurs by the coalescence of clusters, and tens of crystals are found within the bacterial contour. Crystal growth does not affect the viability of the ba...

In a prospective case-control study of sporadic Salmonella Enteritidis infection in Denmark (1997-1999), foreign travel was reported by 25% of 455 case patients and 8% of 507 controls (odds ratio (OR) = 3.7, 95% confidence interval (CI): 2.4, 5.5). Among nontravelers, 80% of 335 cases and 81% of 467 controls had consumed eggs or dishes containing raw or undercooked eggs during the week before d...

The objective of this study was to assess the impact of using heat-denatured whey:buttermilk protein aggregate in acid-set type yogurt production. Whey and buttermilk (25:75) protein concentrate was adjusted to pH 4.6, heated at 90 °C for 5 min, homogenized and freeze-dried. Set-type yogurts were prepared from skim milk standardized to 15% (w/v) total solids and 4.2% (w/v) protein using differe...

The current study was undertaken to determine the 17-β Estradiol (E2) and Progesterone (P4) levels in different milk products some baby follow-on samples collected from retail markets Türkiye. For this purpose, a total of 50 8 product groups with fat levels, production technologies, series were analyzed for natural P4 E2 using commercial ELISA kit. highest level determined UHT whole (3%) (39.20...
