Impact of nutritional information on consumers' acceptance of cheese with reduced sodium chloride content

J. Czarnacka-Szymani, M. Jezewska-Zychowicz

International Dairy Journal > 2015 > 40 > Complete > 47-53

The sensory acceptance of cheese with different sodium chloride contents and the influence of nutritional information on consumers' acceptance and declaration of willingness to purchase the cheeses were assessed. Three samples of cheese with different contents of sodium chloride and two types of nutritional information and nutritional claims were used. No significant differences in acceptance were...

Production of brine-salted Mozzarella cheese with different ratios of NaCl/KCl

Emilie Thibaudeau, Denis Roy, Daniel St-Gelais

International Dairy Journal > 2015 > 40 > Complete > 54-61

Mineral and moisture concentrations, proteolysis, bacterial counts and hardness were assessed in the centre and edge portions of unmelted and melted pizza cheeses, brine-salted with four mixtures of NaCl/KCl. Bacterial counts and proteolysis were not affected by brine solutions. Moisture and Ca were lower at the edge than in centre, whereas an opposite trend was observed for Na and K. This gradient...

The immunological consequences of pasteurisation: Comparison of the response of human intestinally-derived cells to raw versus pasteurised milk

R.J. McCarthy, R.P. Ross, G.F. Fitzgerald, C. Stanton

International Dairy Journal > 2015 > 40 > Complete > 67-72

Microarray technology was used to identify differentially expressed biological signatures in human intestinal cell line (HT-29) exposed to raw versus pasteurised milk; 1041 differentially expressed genes (≥1.3 fold change) were identified (P < 0.001) between exposure groups. These were further identified to be contained within 179 gene ontologies. Genes more highly expressed (599 or 57.5%) in cells...

Physical stability of infant milk formula made with selectively hydrolysed whey proteins

Eoin G. Murphy, Yrjö H. Roos, Sean A. Hogan, Patrick G. Maher, more

International Dairy Journal > 2015 > 40 > Complete > 39-46

A whey protein ingredient, in which β-lactoglobulin was selectivity hydrolysed, was evaluated during manufacturing of infant formulae. Three model infant milk formula (IMF) powders were produced containing: non-hydrolysed (NH) proteins (60:40; whey proteins:caseins); partially hydrolysed (PH) caseins and whey proteins; and selectively hydrolysed (SH) whey proteins. After homogenisation, particle size...

Use of Lactobacillus mucosae DPC 6426, an exopolysaccharide-producing strain, positively influences the techno-functional properties of yoghurt

Lis E.E. London, Valérie Chaurin, Mark A.E. Auty, Mark A. Fenelon, more

International Dairy Journal > 2015 > 40 > Complete > 33-38

The performance of exopolysaccharide (EPS)-producing Lactobacillus mucosae DPC 6426 was evaluated as adjunct culture during low-fat yoghurt manufacture. In situ produced EPS during yoghurt manufacture and storage increased to ∼561.09 mg L ⁻¹ after 28 days of storage. Performance and viability of the yoghurt cultures (∼10 ⁹ cfu mL ⁻¹ ) were not influenced by L. mucosae DPC...

Isolation and identification of a whey protein-sourced calcium-binding tripeptide Tyr-Asp-Thr

Lina Zhao, Xixi Cai, Shunli Huang, Shaoyun Wang, more

International Dairy Journal > 2015 > 40 > Complete > 16-23

A tripeptide peptide with strong calcium-binding capacity was isolated and purified from whey protein hydrolysates using diethylaminoethyl cellulose anion-exchange chromatography, Sephadex G-25 gel filtration, semi-preparative reversed-phase (RP) high-performance liquid chromatography (HPLC) and analytical HPLC. It was identified using liquid chromatography-electrospray ionisation mass spectrometry...

Efficacy of pasteurised yoghurt in improving chronic constipation: A randomised, double-blind, placebo-controlled trial

Zhen-min Liu, Zhi-yuan Xu, Mei Han, Ben-Heng Guo

International Dairy Journal > 2015 > 40 > Complete > 1-5

One hundred and eighteen constipation subjects were fed a placebo or treatment (pasteurised yoghurt) for 7 weeks in a double-blind, randomised, placebo-controlled study. The results suggested that pasteurised yoghurt was effective in improving constipation. The subjects who ingested pasteurised yoghurt showed a significant increase in their defecation frequency following one week of the intervention...

In vitro evaluation of bovine lactoferrin potential as an anticancer agent

Yunlei Zhang, Cristovao F. Lima, Ligia R. Rodrigues

International Dairy Journal > 2015 > 40 > Complete > 6-15

Bovine lactoferrin (bLF) was shown to efficiently inhibit the growth of MCF-7, T-47D, MDA-MB-231 and Hs578T breast cancer cells in a concentration-dependent manner. However, apoptosis was only induced in MCF-7 cells, which was associated with the mitochondria membrane depolarisation and a decrease of Bcl-2 levels. bLF led to the cycle arrest of MCF-7 cells at G1/G0 phase, as well as a significant...

Developing a time and effort-effective, highly sensitive TaqMan probe-based real-time polymerase chain reaction protocol for the detection of Salmonella in milk, yoghurt, and cheese

Walid M. El-Sharoud

International Dairy Journal > 2015 > 40 > Complete > 62-66

A time- and effort-effective, highly sensitive method combining brief pre-enrichment for only 4 h in a non-selective broth and TaqMan probe-based real-time PCR was developed for the detection of different concentrations of a cocktail of 8 Salmonella Typhimurium strains in milk and dairy products. As few as 1 cfu 25 mL ⁻¹ of Salmonella in milk was detectable, and sensitivity was not influenced...

Adherence inhibition of enteric pathogens to epithelial cells by bovine colostrum fractions

Maria X. Maldonado-Gomez, Hyeyoung Lee, Daniela Barile, Mei Lu, more

International Dairy Journal > 2015 > 40 > Complete > 24-32

To initiate colonization, microbial pathogens express adhesins that recognize and adhere to host tissue cells. One strategy for inhibiting adherence relies on the presence of molecules that mimic epithelial receptor sites. In this study, in vitro experiments using HEp-2 cells were performed to assess the anti-adherence properties of bovine colostrum fractions against enteropathogenic Escherichia coli,...
