Abstract

An amylose sponge is obtained by foaming and gelling a dispersion of amylose. The term amylose includes a whole starch which is composed of at least 50% amylose or mixtures of whole starch with at least 50% of amylose. The sponges may be obtained by:- (1) Dispersing amylose in water containing 15 to 50% of an alkali such as an alkali metal hydroxide or a quaternary ammonium base, stabilizing with the addition of any alkali-resistant non-ionic, anionic or cationic surfactant such as "Pluronic" (Registered Trade Mark) F68, Tetronic 908, Igepal CO-880, sodium dodecyl benzene sulphonate and soap and then inflating by adding ammonium oxalate, ammonium gluconate, dibasic ammonium citrate, ammonium chloride, or dibasic ammonium phosphate, or by blowing in an inert gas such as nitrogen, or by the action of acetic acid or citric acid on a carbonate or bicarbonate. The sponges may be washed with distilled water and then with acetone, isopropanol, ethanol, or methanol and finally dried. The product can absorb 10 to 25 times its own weight of water. A plasticizer such as glycerol or diethylene or triethylene glycol may be applied in the form of a solution in ethanol or propanol by spraying into the dried gauze. (2) Dispersing the amylose in water in an autoclave or jet cooker at a temperature above 160 DEG C. and then stabilizing by adding formaldehyde and sodium carbonate solution optionally in the presence of a sodium phosphate buffer. The aerated, stabilized dispersion is cast to the desired shape and gelled by exposure to ammonia, sulphur dioxide or gaseous aliphatic amines. (3) Dispersing the amylose in water at a temperature above 160 DEG C., cooling to 95 DEG C., adding a foam stabilizer and then aerating by beating for 3-7 minutes. After casting into the desired size and shape the sponges are gelled by being allowed to cool for 2-3 hours at room temperature, or by being placed in a refrigerator for 30 minutes.
