The viability of the human probiotic strains Lactobacillus paracasei NFBC 338 and Bifidobacterium sp. strain UCC 35612 in reconstituted skim milk was assessed by confocal scanning laser microscopy using the LIVE/DEAD BacLight viability stain. The technique was rapid (<30 min) and clearly differentiated live from heat-killed bacteria. The microscopic(More)
As a recipient of the Robert Wood Johnson's Pipeline, Profession, and Practice: Community-Based Dental Education grant, the Extramural Education Program (EEP) at the University of Illinois at Chicago College of Dentistry was charged with developing partnerships with community-based oral health programs throughout Illinois. These programs are to be used for(More)
Confocal scanning laser microscopy (CSLM) methods were developed to identify fat and protein in cheeses milk chocolate and milk powders. Various fluorescent probes were assessed for their ability to label fat or protein in selected food products in situ. Dual labelling of fat and protein was made possible by using mixtures of probes. Selected probes and(More)
Rennet-induced coagulation of bovine milk is a complex mechanism in which chymosin specifically hydrolyzes κ-casein, the protein responsible for the stability of the casein micelle. In equine milk, this mechanism is still unclear, and the protein targets of chymosin are unknown. To reveal the proteins involved, the rennetability of equine milk by calf(More)
The effect of tool surface roughness topography on tow-on-tool friction relevant to the dry forming of composite fabrics is investigated. A comprehensive range of tool average surface roughness R a values from 0.005 to 3.2 lm was used in friction testing with carbon fibre tows. The measured slope of these surfaces, which is the critical surface(More)
Whey protein isolate (WPI) solutions, with different levels of aggregated protein, were prepared by heating (5% protein, pH 7, 90°C for 30min) WPI solutions with either 20mM added NaCl (WPI+NaCl), 5mM N-ethylmaleimide (WPI+NEM) or 20mM added NaCl and 5mM NEM (WPI+NaCl+NEM). Gel electrophoresis demonstrated that the heated WPI and WPI+NaCl solutions had(More)
Antifreeze glycoproteins and glycopeptides that function noncolligatively contribute one-third of the freezing temperature depression in the blood serum of some polar fishes and enable them to survive at low temperature (-1.9 degree C). There are at least eight closely related glycoproteins and glycopeptides ranging in molecular weight from 32,000 to 2,600(More)
