Answer to Question 1

Heat the juice and milk separately. Combine when hot. Add juice to milk while stirring slowly. You might also suggest that a white sauce be made. Starch in the white sauce protects the protein. Reheating the soup allows more time for the casein to be involved with the acid. This lowers the pH close to the isoelectric point of the casein protein (4.6). This destabilizes the casein further, and curdling might occur.
