| Abstract: | The refined acorn starch had been turned out from the kernels of wild planted acorn with the quite modern separate machinery and methods since some years ago in China, and was popular with foreign traders. Here, the properties of acorn starch were systematically researched, such as granules and paste. It was showed that the granules of acorn starch with mean size 9.2?μm is quite small, 20.6% amylose content, the gelatinization temperatures from 59.5℃ to 68.0 ℃, its X ray pattern belongs to C type crystal structure. Also the paste of acorn starch has a good stability for viscosity, and its retrogradation is lightly weaker and other properties of the paste are quite similar to that of corn starch. |
