Volatile retention during freeze drying of aqueous suspensions of cellulose and starch

This paper studies the retention of 14C-labeled 2-propanol in freeze-dried starch or cellulose suspensions. Among the variables affecting the retention level are concentration of solids and initial concentration of the alcohol in the suspension. The observed retentions can be explained by inclusion...
