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...

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 within the polymer chains, the pre-dominant mechanism of retention, and adsorption. Cellulose gave a much lower retention than starch, probably because the low mobility of the chains in the highly crystalline cellulose reduces the capacity for retention of the alcohol through inclusion. |
