BACKGROUND Vegetables, apart from having high nutritional value, also contain considerable amounts of dietary fibre and other components, which may affect physico-chemical properties of fermented milks, e.g. viscosity, texture, susceptibility to syneresis, flavour profile etc. The present work was established to study the effect of selected vegetables addition on the rheological, textural, micr...

Among Streptococcus thermophilus cultures, the principle component of yoghurt and cheese starters, a minority of strains forms the group of 'H'-strains which show an unusually high acidification rate, grow faster and coagulate milk 3-5 hours earlier than the typical S. thermophilus cultures. A large-scale screening study was performed to select 'H'-strains of S. thermophilus from more than 100 ...

The objectives of this paper were production of probiotic yoghurt using L. paracasei ssp. tolerans, and evaluation of pH changes, viable counts, and organoleptic properties of the produced yoghurt. It was observed that the pH decrease during the fermentation period was faster in the milk inoculated with L. paracasei ssp. tolerans plus starter culture. There was a gradual decrease in pH in both ...

Post-acidification of set yoghurt always occurs during cold storage causing short shelf life thus consumer unacceptability. The short storage life of particular yoghurt affects the consumption level as well. This study concentrated on the inhibitory effect of preservatives on post-acidification of yoghurt. The set yogurt mixture was produced and inoculated with 2% starter culture containing Str...

The effect of yoghurt and soya yoghurt containing Bifidobacterium lactis Bb-12 or B. longum Bb-46 on Ehrlich ascites tumour cell proliferation was investigated in vitro and in vivo. Tumour cells were incubated with B. lactis Bb-12 or B. longum Bb-46 cultivated in de Mann Rogosa Sharpe (MRS) broth medium, or with their centrifuged supernatant fractions or sediments, for 2 h at 37 degrees C. Trea...

Yoghurt feeding inhibits induced colon cancer in mice. Several studies showed the immunomodulatory effect of yoghurt which can explain this inhibition. It is possible that yoghurt bacteria can also affect gut flora enzymes related to colon carcinogenesis as reported for other probiotics in different animal tumours. The aim of this work was to evaluate the role of yoghurt starter bacteria and th...

Antioxidant rich fruit yoghurt was developed utilizing seabuckthorn fruit syrup using yoghurt culture. The resultant product had higher content of fat, protein, carbohydrate and antioxidants (vitamin C, vitamin E, carotenoids, phenols, anthocyanins) when compared to a commercial yoghurt. The shelf stability studies of yoghurt were assessed at room temperature, 15°C and 4°C. The product stored a...

The effect of adding Saccharomyces boullardii in soya yoghurt was studied. control made with milk and traditional starter culture (Lactobacillus bulgaricus Streptococcus thermophilus) while the other three treatments were by 1%, 2%, 3% S. boulardii starter. Proximate composition all determined after fermentation time. Shelf-life evaluation treatment observed during storage During proximate eval...
