Stirred yoghurts with different fruit homogenates (papaya, kiwi, pineapple and kaki and control (without additive) were prepared and stored up to 14 days at 5±1°C. Sugar and fruit homogenates were added at the rate of 5 and 10% w/w respectively. The results revealed that, significant differences were observed in proteolytic activity, acidity, protein and fibers contents among all treatments. Ad...

Radio frequency (RF) heating was applied to stirred yoghurt after culturing in order to enhance the shelf-life and thereby meet industrial demands in countries where the distribution cold chain cannot be implicitly guaranteed. In parallel, a convectional (CV) heating process was also tested. In order to meet consumers' expectations with regard to texture and sensory properties, the yoghurts wer...

Butyric acid (C4) and pyroglutamic (pGlu) exert significant beneficial effects on human health. In this study, the influence of probiotics (Lactobacillus acidophilus Bifidobacteria) and/or prebiotics (1 3% inulin fructo-oligosaccharides) content C4 pGlu in yoghurt during shelf-life period was evaluated. The contents were determined probiotic, prebiotic synbiotic yoghurts 30 days storage at 4 °C...

Caspian Sea yoghurt has lower acidity and is thicker than common yoghurt. contains probiotic bacteria that improve the balance of intestinal microflora. This research aimed to determine antioxidant activity sea enriched with two different herbs, ginger sappanwood, at concentrations 5, 10 15% w/v. The pH, total phenol, antioxidant, LAB, antibacterial were measured best products. results showed e...

This study examined yoghurt samples produced using classical culture from buffalo’s, goat’s and sheep’s milks in terms of their physicochemical characteristics, DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging activity, angiotensin-converting enzyme (ACE) inhibitory contents total phenolic compounds (TPC), volatile 5-hydroxymethylfurfural (HMF). It was determined that the use differ...

Liquid-enriched powder (LOPP) and pulp-enriched (POPP) obtained from olive pomace were incorporated into yoghurt, not only, to increase its content in dietary fibre, hydroxytyrosol unsaturated fatty acids, but also understand the lipids-phenolics interaction by simultaneous incorporation of oil. POPP (2%) LOPP (1%) addition yoghurt allowed fulfilling condition being a “source fibre” provided 5 ...

Sensory properties and physico-chemical parameters of 10 most popular brands of commercial set-type Turkish yoghurts were evaluated and correlation coefficients between the two indices were investigated. The results indicated that increases in volatile compounds (acetaldehyde, 2-butanone, 2-nanonane, ethyl acetate), titratable acidity, ash and fat contents inversely correlated with the overall ...
