Abstract
Absorption and deterioration of synthetic rubber milker inflations were studied. Synthetic inflations stored in sanitizing solns. were found to absorb various quantities of such solns. during the storage. Significantly higher quantities were absorbed when the inflations were treated by daily working in whole milk for a one minute period followed by solution storage. Inorganic Cl solns. caused greatest deterioration to synthetic inflations as shown by color change, roughening and dissolving conditions on the surface. Lowest absorption occurred when lye soln. was used for storage. A slight tacky feel developed on the surface of inflations stored in acid and "Roccal." A method for determining absorbed fat is described. Highest quantities of fat were absorbed in the mouth or upper portion of inflations. The amt. of absorbed fat decreased as the lye boiling period was extended. Effective reduction was shown in number of heat-enduring bacteria by boiling inflations in a strong lye soln.
