In the second separation of this experiment‚ the Erlenmeyer flask with the first filtrate was put into a beaker so the filtrate was in the beaker. The beaker was then heated on a hotplate until near boiling. After the whey protein had precipitated‚ a vacuum filter was used to filter out the whey. These proteins were then air-dried. A qualitative test was done to indicate that the sample extracted was the protein whey. Again‚ a small test tube was used and 2 mL of protein test solution was put in
