Dairy products containing lactic acid bacteria are often consumed because of the health-promoting activities of some strains of these bacteria as probiotics. It is important that these strains survive the acidic environment of the product since only microorganisms that are alive can be functionally active. This report describes the potential of luctulose to improve the survival of available pro...

Antitumour activity is an effect attributed to probiotics and fermented foods. Here, the immune cells in mammary glands and cytokine concentration in serum were analyzed using mice fed with milk fermented by Lactobacillus helveticus R389 or L89 (proteolytic-deficient variant), injected or not with breast tumour cells. Mice were fed 7 days with fermented milk, injected with breast tumour cells a...

Selenium (Se) is considered as an essential element for human body. Selenized probiotic fermented milk drink (DOOGH) as a functional beverage to increase Se available in body. The predominate sugar, protein and mineral ion of Iranian yoghurt drink (DOOGH) are lactose, casein and calcium, respectively. Different levels of  Selenium (2.5 – 3- 3,5-  4 and 4.5) is prepared and its suitability based...

BACKGROUND We studied the mechanism by which fermented milk ameliorates UV-B-induced skin damage and determined the active components in milk fermented with lactic acid bacteria by evaluating erythema formation, dryness, epidermal proliferation, DNA damage and cytokine mRNA levels in hairless mice exposed to acute UV-B irradiation. METHODS Nine week-old hairless mice were given fermented milk...

The probiotic fermented milk products hold a specific place in the children diet. As rule, pediatricians, when advising parents, are guided by characteristics of both strains used as ferment and included into food product. It is important that microorganisms safe, shelf stable able to survive gastrointestinal tract. use has positive effect on child health, follows: anti-infectious immunomodulat...

Lactic acid bacteria (LAB) are a group of Gram-positive, non-sporulating, low-GC-content bacteria that comprise 11 bacterial genera, such as Lactococcus, Lactobacillus, Leuconostoc, Streptococcus and others (Stiles & Holzapfel, 1997). LAB have a generally regarded as safe (GRAS) Food and Drug Administration (FDA) status, and some strains of different LAB species exhibit also probiotic propertie...

Kefir is becoming increasingly popular as a result of new research into its health benefits. It is a fermented milk drink which has its origin in the Caucasus Mountains of Russia. Kefir is prepared by inoculating milk with kefir grains which are a combination of bacteria and yeasts in a symbiotic matrix. The common microorganisms present are non-pathogenic bacteria, especially Lactobacillus sp....

OBJECTIVE Available reports on adherence to recommended guidelines for labeling of probiotic products are based on assessment of these products in developed countries. In the Arabian Gulf region, there is a paucity of data on the characterization of probiotic products and an absence of local guidelines for their labeling. This study, carried out in the United Arab Emirates (UAE), represents the...

Bacterial exopolysaccharides produced by lactic acid bacteria are of increasing interest in the food industry, since they might enhance the technological and functional properties of some edible matrices. In this work, Pediococcus parvulus 2.6, which produces an O2-substituted (1,3)-β-d-glucan exopolysaccharide only synthesised by bacteria, was proposed as a starter culture for the production o...
