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...

Aim. The objective was to evaluate the synergistic effects of fermented rice extracts (FRe) on the laxative and probiotic properties of yoghurt in rats with loperamide-induced constipation. Methods. After constipation induction, yoghurt containing FRe (BFRe; 0.05%, 0.1%, or 1%) was administered orally once per day for 6 days. Results. Loperamide treatment caused marked decreases in fecal pellet...

BACKGROUND Probiotics are used to provide health benefits. The present study tested the effect of a probiotic yoghurt on faecal output of beta-defensin and immunoglobulin A in a group of young healthy women eating a defined diet. FINDINGS 26 women aged 18-21 (median 19) years residing in a hostel were given 200 ml normal yoghurt every day for a week, followed by probiotic yoghurt containing B...

This first part of a two-part study focuses on the technical feasibility of applying radio frequency (RF) heating at different temperatures (58, 65 and 72 °C) to a stirred yoghurt gel after culturing. For comparison, a convectional (CV) heating process was also applied. The aim was to increase the yoghurt shelf-life, by preventing post-acidification and the growth of yeasts and molds. At the sa...

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 ...

Probiotic foods are defined as “foods containing live microorganisms, which actively enhance health of consumers by improving the balance of microflora in the gut when ingested live in sufficient numbers” (Fuller, 1992; Shah, 2004). In terms of the growth and viability of probiotic bacteria in retail products, fermented milks are excellent vehicles for the transfer of selected strains to humans...

Yoghurt is a unique fermented dairy product, consumed throughout the world and the trend ofconsumption is increasing due to its unique health benefits. Yoghurt mix is often supplemented with MSNF(milk solids-non-fat), it may contain as much as 5.7% unhydrolysed lactose. Lactose can be hydrolysed withan enzyme lactase. Deficiency of lactase in lactose-intolerant persons leads to gastrointestinal...

Our main goal in this project is to study the causes and finding solutions for both the hydrolytic and the oxidative rancidity that can be produced during condensed yoghurt production. The re pasteurization of the pasteurized milk and the addition of different types of antioxidants (ascorbic acid and propyl gallate) were used to achieve this goal. Chemical, physical, microbial and sensory tests...

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 aim of this study was to determine the suitability of different doses (0, 0.4, 0.8 and 1.2%) of coffee extract on fermentation and survival of Lactobacillus acidophilus and Bifidobacterium bifidum in milk and yoghurt. The produced samples were examined in terms of pH, acidity and microbial count during incubation period and permanence. The number of Lactobacillus acidophilus and Bifidobacte...
