GB/T 12087-2008 Starch - Determination of moisture content - Oven-drying method



1 Scope



This standard specifies a method for the determination of the moisture content of starch using oven-drying at 130℃ under atmospheric pressure.



This standard is applicable to native or modified starch in the dry form.



In special circumstances, for example if the starch contains substances which are unstable at 130℃, this standard is not applicable.



2 Terms and definitions



For the purposes of this standard, the following terms and definitions apply.



2.1

moisture content of starch

loss in mass of the test sample under the test conditions specified in this standard, expressed as a percentage by mass



3 Principle



Dehydration of the test sample in a drying oven at 130℃ to 133℃, under atmospheric pressure, for a period of 90min.



4 Apparatus



Usual laboratory apparatus and, in particular, the following.



4.1 Analytical balance, capable of weighing to the nearest 0.001g.



１９８９相比，本标准在精密度和实验报告上作了具体要求，对常见的七种类型淀粉的重复性和再现性作了明确要求；并增加了附录Ａ。
