abstract the objective of this study was to determine the effect of psychrotrophic bacteria and somatic cells on the physicochemical characteristics of iranian ultrafiltered (uf) white cheese. milks with different numbers of psychrotrophic bacteria (1×106, 5×106 and 10×106 cfu/ml) and low somatic cell counts (scc, <2×105/ml) were selected and uf white cheese trials were produced. in a separate ...

Pulp (CP) and ultrafiltered (UF) cactus pear extracts were encapsulated with Capsul (C) by applying a central composite design (CP-C and UF-C systems) by spray-drying. To evaluate the effect of the extract, microparticles obtained under optimal conditions were characterised and stored at 60 °C. Betacyanin and betaxanthin encapsulation efficiency reached values above 98% for both systems studied...

Application of combined ultrafiltration (UF) and nanofiltration (NF) was examined to recycle cellulase and concentrate glucose present in lignocellulosic hydrolyzate. With PES10 membrane operated at 25.6 l/m(2) h, 73.9% of cellulase protein present in the hydrolyzate suspension could be recovered while allowing free transmission of glucose. The permeate obtained from UF was then concentrated by...

changes in the fatty acid (fa) composition of iranian uf (ultrafiltered)-feta cheese during ripening (3, 20, 40 and 60 days) were studied. with an increase in the ripening period, due to the conversion of fa to secondary metabolites, the percentages of c4:0-c12:0 decreased significantly (p

Pasteurization parameters for grade A milk are well established and set by regulation. However, as solids levels increase, an increased amount of heat is required to destroy any pathogens present. This effect is not well characterized. In this work, the effect of increased dairy solids levels on the thermal resistance of Listeria monocytogenes was examined through the use of ultrafiltered (UF) ...

Our aim was to determine whether fractionation of human urine affects the attachment of calcium oxalate monohydrate (COM) crystals to renal cells. Urine collected from six healthy subjects was fractionated into sieved (S), centrifuged (C), centrifuged and filtered (CF), or ultrafiltered (UF). Attachment of [(14)C]COM crystals to Madin-Darby canine kidney (MDCK) cells was studied after precoatin...

In this study, two packaging materials, modified polypropylene (MPP) and polyethylene terephthalate/aluminum/ low-density (PETFA-Al-LDPE) were studied under various atmospheric conditions: 100 % CO2, 70 N2 - 30 80 20 CO2 for packing probiotic ultrafiltered (UF) white brined cheese. pH, titratable acidity, moisture content, Lacticaseibacillus paracasei viability overall acceptability monitored w...

In the pulp and paper industry, the water use minimization is a constant target. One way to reduce water use is to recycle the effluent in a closed-cycle concept. In paper mills, the main source of liquid effluent is the so-called whitewater, which is the excess water, originated from pulp stock dewatering and other fibre contaminated water. This research studied the reuse of paper mill whitewa...

Following increasing interest in the use of UltraFiltration (UF) membrane processes as an alternative advanced disinfection technique, the performance of a UF pilot plant was investigated under two opposite operating conditions (“stressed operating condition” versus “conventional operating condition”). The results indicate that for both conditions, the reclaimed effluent complied with the Itali...

The effect of ultrafiltration and diafiltration on the distribution of the calcium phosphate clusters of the casein micelle was investigated using Small Angle Neutron Scattering (SANS). In the case of ultrafiltration, fresh skim milk was subjected to concentration using membrane filtration up to 5× its original volume, the retentate was rediluted with its corresponding serum and subsequently di...
