In this lab, the study and experimentation of 2 concentration processes example evaporation concentration and Freeze Concentration. The sample used for this concentration is pineapple juice, which studies and experiments show that The weight of the water evaporated from the Evaporation process is greater than the Freeze concentration process. And freeze concentrations process have an efficiency of 85% separation of water. According to studies and experiments, both concentrations of food have sensory changes such as color and flavor after concentration. different And also resulting in different pH and% Brix after concentration
