The aim of this study was to evaluate the goat milk mineral performance concentrated by block freeze concentration process. Twenty batches of skim goat milk, each one with one liter, were subjected until the third stage of the freeze concentration process. The initial skim goat milk, concentrated, and ice fractions obtained were analyzed by calcium, magnesium, zinc, phosphorus, sodium and potassium content. Results showed that phosphorus content not increased (P < 0.05) with the increase of freeze concentration stages, for concentrated and ice fractions. In the first stage of freeze concentration process, the magnesium element showed the higher (P < 0.05) efficiency (95%). However, the higher (P < 0.05) concentration factor was determinate to calcium element in the third stage of the process. Also, it was observed an increase in the minerals contents evaluated with the increasing of freeze concentration stages of skim goat milk. Based on results obtained in the present study, the skim goat milk concentrated obtained in the first stage showed the best performance of skim goat milk mineral content concentration.

Heat Transfer Efficiency

In this research, coconut water was concentrated by applying progressive freeze concentration (PFC) using coil crystallizer. Overall heat transfer coefficient (U) was analyzed from the process by varying different coolant temperature values since both of them are closely related. In this case, heat transfer efficiency depends strongly on ice crystal formed on the inner cooled surface and is explained theoretically from that angle. At optimum flowrate, operation time and initial concentration best results were observed at-10oC of coolant temperature where the concentration efficiency and effective partition constant (K) obtained were 48% and 0.2 respectively. Meanwhile, U obtained at the first and second stages were 183.0046 W/m2oC but dropped at lower value at later stage at 154.9625 W/m2oC due to ice fouling.
