Capsule formation by nonropy starter cultures affects the viscoelastic properties of yogurt during structure formation.
The aim of this work was to study the structure formation of yogurt made with cultures containing ropy Lactobacillus delbrueckii ssp. bulgaricus (R), capsule-forming nonropy Streptococcus thermophilus (CNR), and noncapsule-forming nonropy cultures (NCNR). Similar gelation profiles were shown for milk fermented by ropy and nonropy lactic cultures. The gelation point occurred at lower pH values i...
متن کاملMicrostructure and rheology of yogurt made with cultures differing only in their ability to produce exopolysaccharides.
Yogurt was made using an exopolysaccharide-producing strain of Streptococcus thermophilus and its genetic variant that only differed from the mother strain in its inability to produce exopolysaccharides. The microstructure was investigated using confocal scanning laser microscopy, allowing observation of fully hydrated yogurt and the distribution of exopolysaccharide within the protein network....
متن کاملDetermination of Yogurt Quality by Using Rheological and Textural Parameters
Sensory and textural parameters of yogurt are known to have an important impact on food quality and acceptability. The emphasis in this article is to summarize the rheological and textural parameters of yogurt. Viscosity, hardness, adhesiveness, cohesiveness, and springiness are considered the most important descriptors for the textural perception of yogurt. Factors affecting textural propertie...
متن کاملAntimicrobial properties of lactic acid bacteria isolated from traditional yogurt and milk against Shigella strains
Background: Lactic acid bacteria (LAB) are normal flora of the mouth, intestines and the female genital tract. They are also frequently found in meat, vegetables, and dairy products. Most of probiotic bacteria belong to the LAB group. Some probiotic LAB are useful in prevention and treatment of diarrheal diseases. The aim of this study was to investigate the antimicrobial properties of LAB isol...
متن کاملYogurt, living cultures, and gut health.
Bacteria used to ferment milk to obtain yogurt belong to thermophilic, bile-sensitive species of lactic acid bacteria, which are not ideally suited for survival into the human gut. However, assessing the viability of these bacteria through the digestive tract may be relevant to evaluate their potential to deliver some beneficial effects for the well-being of the consumer. The well-known reducti...
