Effects of seasonal variations on the quality of set yogurt, stirred yogurt, and Greek-style yogurt

چکیده

We studied the effects of seasonal variations on quality stirred yogurt, set and Greek-style yogurt over 2 milking seasons in New Zealand. Correlations between properties yogurts, characteristics milk, acid gelation induced by glucono-?-lactone, reported our previous works, were also explored. Set from early season had highest firmness seasons. The correlated with gel strength glucono-?-lactone-induced gels, indicating that latter could, to some extent, predict yogurt. correlation studies highlighted potentially important role glycosylation ?-casein structures. Yogurt made mid-season milk lowest water-holding capacity, which may have played a part lowering its viscosity. Late-season displayed strongest resistance shear-induced thinning, might arise unique viscoelastic late-season gels.

Manufacture and quality of iron-fortified yogurt.

Yogurts (nonfat and low fat) were manufactured and fortified with 10, 20, and 40 mg of iron/kg of yogurt. Growth of starter culture bacteria and nonstarter culture bacteria as well as lipid oxidation of the yogurts were monitored over 30 d of storage at 4 degrees C. Sensory characteristics of the yogurts were determined during that time by a trained panel of judges, and consumer panels were use...

Behavior of Heat-Denatured Whey:Buttermilk Protein Aggregates during the Yogurt-Making Process and Their Influence on Set-Type Yogurt Properties

The objective of this study was to assess the impact of using heat-denatured whey:buttermilk protein aggregate in acid-set type yogurt production. Whey and buttermilk (25:75) protein concentrate was adjusted to pH 4.6, heated at 90 °C for 5 min, homogenized and freeze-dried. Set-type yogurts were prepared from skim milk standardized to 15% (w/v) total solids and 4.2% (w/v) protein using differe...

Effect of purified oat β-glucan on fermentation of set-style yogurt mix.

UNLABELLED Effect of oat β-glucan on the fermentation of set-style yogurt was investigated by incorporating 0%, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% of purified oat β-glucan into the yogurt mix. It was found that levels up to 0.3% resulted in yogurts with quality characteristics similar to the control yogurt. Higher levels of β-glucan however retarded the fermentation process with noticeable differ...
