用两种方法测定莲子中直链淀粉含量的研究

建立了采用莲子直链淀粉作标准曲线定量测定莲子中直链淀粉含量的方法，即在650rim处用分光光度计测定直链淀粉一碘复合物的吸光度，再通过标准曲线计算得到莲子样品中的直链淀粉含量。与GB／T15683--2008（采用马铃薯直链淀粉作标准曲线）所测定得到的莲子中直链淀粉含量结果比较，该方法所得到的结果明显低些，但更准确些。...

Potato; Lotus seed; Amylose; Determination; Method
A method for the quantitative determination of amylose content in lotus seeds was established by using lotus-seed amylose to make a standard curve. In other words, the absorbance of the compound of lotus-seed amylose and iodine was tested with spectrophotometer at 650 nm, and then the amylose content in lotus seed samples was acquired by the above standard curve. In com- parison with the lotus-seed amylose content obtained by GB/T 15683--2008, in which potato amylose was used to make a standard curve, the result obtained by this method was obviously lower, but was more accurate.
