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...

Introduction: Nowadays, thanks to improvements in fruit yoghurt tastes, more tendencies are seen in their consumption especially among children. Therefore, their cariogenicity evaluation as healthy snacks is important. The goal of this study was the assessment of the consumption effect of two kinds of Iranian fruit (apple) and plain yoghurts on dental plaque PH. Methods: In this experimental st...

nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. analyses included total nitrogen (tn), non-casein nitrogen (ncn), non-proteinnitrogen (npn), casein nitrogen (cn) and proteolysis index (pi). yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°c. tn, cn and pi contentsof yoghurt milk samples with high somatic cell sc...

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...

ABSTRACT: Yoghurt is a popular healthy food, consumed by many people. The popularity of this product made it possible to use it as a base in order to produce probiotic preparations. Prebiotics are used for better growth and survival of probiotic bacteria as well as to improve organoleptic, rheological and technological properties of probiotic yoghurt. The aim of this research was to study physi...
