“…Considering that the samples had slab format, the mass transfer can be simplified using a 1d model related to the thickness of the slab. Assuming that the brine concentration remained constant throughout the process, the external resistance to mass transfer was insignificant in relation to the internal resistance and the sample volume remained constant, the mathematical model based on Fick's second law can be used to determine the salt diffusion coefficients in salted meat (Crank, 1975; Dimakopoulou‐Papazoglou & Katsanidis, 2019a). The NaCl diffusion coefficients are calculated using Equation 6: Cs,tCs,eqCs,0Cs,eq=n=08()2ngoodbreak+12π2e()Dnormals()2ngoodbreak+12π2tL2 where C s , t is the salt content (%) at a given time t (s); C s , 0 is the initial salt content in the meat; C s , eq corresponds to the equilibrium salt content (%); D s represents the effective salt diffusion coefficient (m 2 /s); L is the thickness of the meat (m).…”

“…Bu nedenle, çözeltinin ozmotik basıncının işlem boyunca korunmasını sağlamak için, uygun ozmotik çözelti/örnek oranı seçilmesi önemlidir (Dimakopoulou-Papazoglou & Katsanidis, 2020). Literatür incelendiğinde, ozmotik çözelti konsantrasyonunun minimum değişimde kalmasının hedeflendiği ve ozmotik dehidrasyon boyunca, çözelti/örnek oranının 10:1 ve üzerinde birçok çalışma olduğu gibi (Bampi ve ark., 2016;Chabbouh ve ark., 2012;Dimakopoulou-Papazoglou & Katsanidis, 2019), daha düşük çözelti/örnek oranının (5:1) kullanıldığı çalışmalar da bulunmaktadır (Curcic ve ark., 2014;Ćurčić ve ark., 2013;Filipović ve ark., 2017;Filipović ve ark., 2014;Filipović ve ark., 2012;Pezo ve ark., 2013). Ayrıca, bu düşük çözelti/örnek oranının, herhangi bir konsantrasyon değişikliğine sebep olmayacagı da belirtilmiştir (Filipović ve ark., 2012).…”

“…In recent studies, many researchers have tried a variety of low sugar solutions, including polyols and low-sugar fruit juice, to reduce the calorie content and glycemic index of dehydrated products (Cichowska et al, 2018;Akharume et al, 2016). The high viscosities of sucrose, polyols and low-sugar fruit juice solution limits their applications in the OD of blueberries at low temperature (<25 °C), and many physicals methods, such as vibration and stirring, cannot improve the efficiency (Dimakopoulou-Papazoglou & Katsanidis, 2019;Telis et al, 2004;Tonon et al, 2007). Higher temperature can improve the OD efficiency, but high temperature is harmful to the anthocyanins and phenols in blueberries (Allan-Wojtas et al, 2001;Yu Y et al, 2017).…”

“…Anthocyanins are antioxidants and important solutes in a healthier product (Grajales-Lagunes et al, 2019). To improve the efficiency of OD for blueberries, the use of a ternary solution can increase the osmotic pressure gradient of the solution without reaching the saturation limit of the OD solute (Dimakopoulou-Papazoglou & Katsanidis, 2019;Telis et al, 2004;Derossi et al, 2015). Sodium chloride (NaCl) is a common OD solute in ternary solutions (Telis et al, 2004;Tonon et al, 2007;Derossi et al, 2015).…”
