The effect of yoghurt and curd cheese additions on pasting properties, starch digestibility estimated glycemic index wheat bread were studied. Yoghurt incorporations (6% up to 25% w/w) promoted considerable changes performance based gelatinization final dough consistency properties. These led a significant impact digestibility, reducing significantly the rapidly digestible while increasing resi...

This study aimed to isolate and characterize viable lactic acid bacteria (LAB) from the most popular in Bulgaria fermented milk products. Different samples from home-made cheeses, yoghurt and katak, from ecological regions of Stara Planina, Rila and Rodopi mountains were collected. A total of 25 LAB cultures (coci and rods) were isolated and polyphasic taxonomic characterization was performed. ...

The objectives of this study were to assess the microbiological quality of Egyptian yoghurt and to investigate the antagonistic activity of some probiotic bacteria against some food borne pathogens in vitro and in yoghurt. The results indicated a poor microbiological quality of yoghurt, since the microbiological parameters recorded higher values than the admissible levels. Results from the agar...

In this study, CFD calculations were made in order to analyse the thermal behaviour of yoghurt in a plate heat exchanger, the yoghurt viscosity being described by a Herschel–Bulkley model. The influence of Reynolds number on local Nusselt numbers was analysed as well as the influence of entry effects on average Nusselt number. Numerical runs considering and discarding the influence of temperatu...

background and objective : mozzarella is a soft cheese belonging to the pasta filata family, containing 18-24 % fat. the objective of this study was to determine the effect lowering mozarella fat content to 6% and adding whey protein concentrate on the rheological properties of the low-fat cheese. materials and methods : low-fat mozzarella was produced using 3 fat replacers ( dairy-lo, 35% prot...

In the present study, an attempt has been made to assess the probiotic characteristics of lactobacilli and yeast strains isolated from whey beverage under conditions simulating the in vivo stresses encountered in the gastrointestinal tract i.e. acid, alkaline, proteolytic enzymes and bile stress. The therapeutic potential of probiotics Lactobacillus casei or Lactobacillus yoghurt was assessed i...

In the present work, simulations of stirred yoghurt processing in a plate heat exchanger were performed using computational fluid dynamics (CFD) calculations and the results compared with experimental data, showing a very good agreement. A Herschel–Bulkley model for the viscosity and an Arrhenius-type term for the temperature dependence were used to model the thermo-rheological behaviour of yog...

Lactic acid bacteria (LAB) are present in many foods such as yoghurt and are frequently used as probiotics to favour some biological functions in the host. Many investigators have evaluated the therapeutic effects of yoghurt and LAB commonly used in yoghurt production against diseases such as cancer, infection, and gastrointestinal disorders. The increase of immune cell activity in the preventi...
