The aim of this study was to determine the suitability of different doses (0, 0.4, 0.8 and 1.2%) of coffee extract on fermentation and survival of Lactobacillus acidophilus and Bifidobacterium bifidum in milk and yoghurt. The produced samples were examined in terms of pH, acidity and microbial count during incubation period and permanence. The number of Lactobacillus acidophilus and Bifidobacte...

OBJECTIVE The aim of the study was to determine the relationship between fermented and unfermented dairy product consumption and Helicobacter pylori seropositivity in a Mexican population. DESIGN Dietary interviews were conducted as part of a population-based case-control study in 2005. Serum was obtained for each participant to determine H. pylori seropositivity status. Adjusted odds ratios ...

BACKGROUND/AIMS While probiotic bacteria are successfully used in the treatment of ulcerative colitis, the effect of commercially available probiotic products is still controversial. Here, we study whether the number of living probiotic bacteria in yoghurts is altered by an interruption of the cold chain. METHODS Three commonly available probiotic yoghurts were kept at 4°C or put at room temp...

Three yoghurt-based weaning foods (WF1, WF2 and WF3) designed for 1-3 years old toddlers which prepared by blending of mung beans (Vigna radiata), soybean (Glycine max) and brown rice (Oryza sativa), were evaluated for their chemical, physical, microbial and organoleptic properties. Proximate compositions of the yoghurt-based weaning foods were varied significantly (P<0.05) and fulfilled the nu...

This study evaluated the stability of Bifidobacterium lactis (Bb-12) and of Lactobacillus acidophilus (La05) both free and immobilized in calcium alginate, in milk and in acidified milk (pH 5.0, 4.4 and 3.8). The stability of immobilized B. lactis in yoghurt (fermented to pH 4.2), during 28 days of refrigerated storage was also evaluated. The efficiency of two culture media (modified MRS agar a...

The objective of the present study was to assess the effect of consumption of a yoghurt-based drink enriched with 1-2 g plant sterols/d on serum lipids, transaminases, vitamins and hormone status in patients with primary moderate hypercholesterolaemia. Thirty patients were randomly assigned to one of two treatment groups: a low-fat low-lactose yoghurt-based drink enriched with 1 g plant sterol ...

The aim of this study was to investigate the influence of proteolytic pork hydrolysate (PPH) on yoghurt production by Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus. Fresh lean pork was cut into pieces and mixed with deionized water and dealt with protease, then the resulting PPH was added to milk to investigate the effects of PPH on yoghurt production. The fermentat...
