The effects of the addition of whey protein concentrates and clarification by-products obtained from ovine cheese whey and deproteinized whey (Sorelho) on the yield and quality of the whey cheese (Requeijão) have been evaluated. Whey protein concentrates were obtained by ultrafiltration of skimmed whey and Sorelho. The clarification by-products were obtained after the treatment of the skimmed w...

This research was carried out at the laboratories of Food Science Department, Faculty of Agriculture, Damascus University, to investigate the effect of high temperatures on accelerating the ripening of kachcaval cheese, through determining the chemical and sensory indicators of ripened cheese using three temperatures (16°C, 20°C for a week) then completing the ripening process up to 60 days at ...

A moderate high-pressure processing (HPP) treatment is proposed to accelerate the shredability of Cheddar cheese. High pressure processing (345 and 483 MPa for 3 and 7 min) applied to unripened (1 d old) stirred-curd Cheddar cheese yielded microstructure changes that differed with pressure level and processing time. Untreated and pressure-treated cheese shredded at d 27 and 1, respectively, sha...

Cottage cheese was produced from reconstituted skimmed milk powder Fer­ mentation of skim milk with approximately 11.16% total solids was performed at 22 °C with 0,5% mesophilic starter culture, "O" type (DVS, Chr Hansen's Lab), without rennet addition. Dry Cottage cheese samples contained an average 21,32% total solids; 17.85%) proteins; 0.75%) ash; and 90.33 mg Ca/lOOg. The Cottage cheese pro...

The production of dairy products is classified as an energyconsuming industry, which due to the use heat exchange processes involving steam a carrier. Indicators energy efficiency and conservation in fermented milk products, including cottage cheese, may sharply decrease violations fermentation process raw milk. intervention biological factor – development viruses that lyse cells lactic acid ba...

The fate of 5 different Escherichia coli strains, including 3 Shiga toxin-producing E. coli (STEC) strains, was analyzed during the production and ripening of semihard raw milk cheese. The strains, which were previously isolated from raw milk cheese, were spiked into raw milk before cheese production at 2 different levels (approximately 10(1) and 10(3) cfu/mL, respectively). Two cheese types we...

The fate of ivermectin (IVM) residues was studied throughout the processing of daily bulk milk from 30 ewes (taken up to 33 d following subcutaneous administration of 0.2 mg IVM/kg b.w.) in the following milk products: yoghurt made from raw and pasteurized milk; cheese after pressing; 30- and 60-day ripened cheese; and whey, secondary whey and whey proteins obtained after cheese-making (albumin...

Cheese, a product of microbial fermentation may be defined as a protein matrix entrapping fat, moisture, minerals and solutes as well as dispersed bacterial colonies. The growth and physiology of bacterial cells in these colonies may be influenced by the microenvironment around the colony, or alternatively the cells within the colony may modify the microenvironment (e.g., pH, redox potential) d...

Our objective was to develop a rapid method for measuring fat, protein, solids, and salt content of Cheddar cheese using a mid-infrared (MIR) transmittance analysis. Currently, quality assurance is done using near-infrared (NIR). For MIR analysis, Cheddar cheese (about 9 g) was blended with a sodium metasilicate solution (about 85 g). Cheese was blended to a uniform particle size (about 3 to 4 ...

BACKGROUND Older adults, pregnant women, and persons with immunocompromising conditions are at higher risk than others for invasive Listeria monocytogenes infection (listeriosis), a rare and preventable foodborne illness that can cause bacteremia, meningitis, fetal loss, and death. METHODS This report summarizes data on 2009-2011 listeriosis cases and outbreaks reported to U.S. surveillance s...
