Evaluation of the functional efficacy of an antioxidative probiotic in healthy volunteers
BACKGROUND: In persons without clinical symptom it is difficult to assess an impact of probiotics regarding its effect on health. We evaluated the functional efficacy of the probiotic Lactobacillus fermentum ME-3 in healthy volunteers by measuring the influence of two different formulations on intestinal lactoflora, fecal recovery of the probiotic strain and oxidative stress markers of blood and urine after 3 weeks consumption. METHODS: Two 3-week healthy volunteer trials were performed. Open placebo controlled (OPC) study participants (n = 21) consumed either goat milk or by L. fermentum ME-3 fermented goat milk (daily dose 11.8 log CFU (Colony Forming Units). Double blind randomised placebo controlled (DBRP) study participants (n = 24) received either capsules with L. fermentum ME-3 (daily of dose 9.2 CFU) or placebo capsules. The faecal lactoflora composition, faecal ME-3 recovery, effect of the consumption on intestinal lactoflora, and oxidative stress markers of blood (total antioxidative activity; total antioxidative status and glutathione red-ox ratio) was measured. RESULTS: ME-3 was well tolerated and a significant increase in total faecal lactobacilli yet no predominance of ME-3 was detected in all study groups. Faecal recovery of ME-3 was documented by molecular methods only in fermented milk group, however the significant improvement of blood TAA (Total Antioxidative Activity) and TAS (Total Antioxidative Status) indices was seen both in case of fermented goat milk and capsules", yet glutathione re-ox ratio values decreased only in case of fermented by ME-3 goat milk. CONCLUSION: The functional efficacy of both consumed formulations of an antioxidative probiotic L. fermentum ME-3 is proved by the increase of the intestinal lactobacilli counts providing putative defence against enteric infections and by reduction of the oxidative stress indices of blood and urine of healthy volunteers. In non-diseased host the probiotic health claims can be assessed by improvement of some measurable laboratory indices of well-established physiological functions of host, e.g. markers of antioxidative defence system

White-brined cheeses
This chapter discusses various white-brined cheeses, including Batzos PDO, Turkish Beyaz Peynir, Feta, Halitzia, Halloumi, Mihalic, Sjenica, and Urfa. Turkish Beyaz Peynir is a rindless, white-coloured, close-textured variety with a salty acid taste; it may have a slight piquant flavour, especially when made from sheep's milk. A number of volatile compounds are produced by defined or wild-type lactococcal bacteria used in the manufacture of Turkish Beyaz Peynir. The geographical region of Sjenica cheese production is in the Sjenicko-Pesterska plateau, which is located in the southwestern part of Serbia and represents the biggest plateau in the Balkan, which includes the municipalities Sjenica and Tutin. Sjenica cheeses are home-made cheeses, manufactured at farms or produced in small dairy craft plants. Urfa cheese variety is mainly produced from raw sheep's milk (mainly milk of the Awassi sheep breed) or an appropriate mixture of sheep's and cow's milks. © 2018 John Wiley & Sons, Ltd.

Pasta-filata cheeses
This chapter discusses various kinds of Pasta-Filata cheeses, such as Caciocavallo Podolico PDO, Kachkaval, and Kashar. Kashkaval-type Kashar cheese is common in the Trakia region. Kashar cheese is a hard cheese with no holes but a rind, and it is yellowish in colour. Kasseri has a closed texture with no holes and a mild, mellow, faintly sweet flavour. The flavour is more pronounced when cheeses are well matured. Ragusano PDO is a stretched-curd cheese made with cow's raw whole milk. It is a high in fat and protein cheese, and it has a low moisture content when aged. Ragusano PDO has a parallelepiped shape with a square section and rounded corners. Parenica is a pasta-filata-type cheese, made from full-fat sheep's milk that is not heat-treated. The most characteristic feature of Parenica is its unique form of the double ribbon, as well as its stringy structure and attractive, softly acidic flavour with the sheep's milk overtones. © 2018 John Wiley & Sons, Ltd.
