Proteases of Lactobacillus and Lactococcus strains catalyze casein degradation in fermented dairy products, which can result the production bioactive peptides. Proteolytic properties a selection lactic acid bacteria (LAB) previously isolated Croatia, including lactis strains, are described. All showed an Fmc+ phenotype that be associated with efficient growth milk. The significant caseinolytic ...

comin the case of pharmaceutical processes, the presence of preservatives can be problematic and the quantity is subject to stringent standards. so, the aim of this study is to quantify the removal of glycerin contained in ultrafiltration flat sheet membranes by filtration and soaking. this is carried out over a wide range of membranes with different characteristics. the selected flat sheet mem...

The aim of this study was to produce a colloidally stable whey protein concentrate enriched in β-casein. Microfiltration (MF) skim milk completed at ∼7 °C (pore size 0.1 μm) followed by ultrafiltration the MF permeate ∼9 β-casein-whey fraction (BWPC). casein:whey ratio BWPC system ∼25:75. Skim then added retentate level supplying 0, 0.1, 0.3 and 0.5% (w/w) total protein, evaporation spray dryin...

The physical and chemical changes of 4x milk concentrates prepared by ultrafiltration (UF) microfiltration (MF) combined with diafiltration were studied after heating in situ to 85 °C subsequent cooling. Skim (1x) was analyzed as control. had comparable pH, colloidal casein calcium phosphate, but differed whey proteins serum allowing investigating the effect soluble phase composition on viscosi...

OBJECTIVE Current determinations of diagnostic ultrasound exposure parameters (eg, peak rarefactional pressure and pulse intensity integral) are intended to correspond to propagation through soft tissue with a propagation speed of 1540 m/s and attenuation of 0.3 dB x cm(-1) x MHz(-1). These current measurements are made in water, which has very little attenuation, and a linear derating factor i...
