“…Zwiększenie udziału poszczególnych preparatów białkowych w produktach powodowało stopniowy spadek ilości wydzielanej serwatki. Zmniejszenie poziomu synerezy w mlecznych napojach fermentowanych na skutek dodatku białek serwatkowych opisano dotychczas w kilku pracach naukowych [15,22,25].…”

“…[28]. Większa zdolność wiązania wody w produktach G' G" δ T wzbogaconych dodatkiem koncentratu białek serwatkowych może być tłumaczona wyższym poziomem usieciowania tych skrzepów w porównaniu z jogurtami kontrolnymi [25,27]. Otrzymane mleczne napoje fermentowane przechowywano przez 21 dni w warunkach chłodniczych.…”

“…Up to now, some work describing factors that promote the particle growth in dairy products during pre-processing and fermentation has been published: regarding a decreasing fat content and an increasing protein content (Ciron et al 2010;Janhøjetal.2009;Johansen et al 2008;R a s m u s s e ne ta l .2007), a decreasing dry matter of milk (Küçükçetin et al 2008), a decreasing heating temperature and a decreasing casein to whey protein ratio (Küçükçetin 2008;Lucey and Singh 1997;Puvanenthiran et al 2002), the choice of cultures (Küçükçetin et al 2009;S o d i n ie ta l .2005), the fermentation conditions (Aichinger et al 2003;Lucey and Singh 1997), the final pH (Johansen et al 2008), or the rennet activity (Aichinger et al 2003). At the present time, stabilizers are often empirically added in order to correct structural defects like graininess or syneresis (Lucey and Singh 1997).…”

“…In addition, the preparation of yoghurt from homogenized milk coats the increased surface of fat globules with casein, enabling the fat globules to participate as a copolymer with casein to strengthen the gel network (Everett and McLeod, 2005). Puvanenthiran, Williams and Augustin (2002) found in their study on set yoghurt that as the casein (CN) to whey protein (WP) ratio was decreased the maximum gel strength of the yoghurt increased. Scanning electron microscopy indicated that gels with a lower proportion of casein had a finer structure with numerous small pores and a dense network of crosslinks (Puvanenthiran et al, 2002).…”

Scanning electron microscopy indicated that gels with a lower proportion of casein had a finer structure with numerous small pores and a dense network of crosslinks (Puvanenthiran et al, 2002). Similar results have been reported by Kücükcetin (2008) that as CN to WP ratio increased in the stirred yogurt the number of grains, perimeter of grains, visual roughness, storage modulus and yield stress decreased.…”
