Densities, viscosities and water activities of ternary NaCl-glucose syrup-water systems from 283.1 to 298.1 K

摘要: The densities and viscosities of ternary NaCl–glucose syrup–water systems were measured in the 283.1–298.1 K temperature range water activities at 298.1 K. NaCl glucose syrup molalities ranged from 0 to 6.0 mol kg � 1 1.91 , respectively. ‘‘Dextrose equivalent’’ (DE) value was 21 median molecular weight 1.007 (kg ). Experimental density, viscosity activity data fitted by a five-parameter correlation, an eight-parameter polynomial respectively with deviations less than 0.5%, 2.3% 0.9%, presence found be responsible for excess volume. There major contribution interaction terms calculation viscosity, particularly high viscosity. While these are used dehydration–impregnation soaking (DIS) process, technological consequences findings discussed DIS process optimization, mass transfers, solution management. 2004 Elsevier Ltd.
