| 摘 要： | 提出了一种基于计算机色度学原理的稻米直链淀粉含量检测方法。探讨了利用扫描仪代替传统的分光光度计 ,通过一次性采集样液的色度值 ,同时测定多个稻米样品的直链淀粉含量 ,并自动确定其所属等级的可能性。研究结果表明 ,显色液的色度值与直链淀粉质量浓度具有良好的线性相关性 (相关系数为 0 980 ) ,所提出的新型直链淀粉含量简化测定方法具有成本低、效率高、对环境条件的要求相对宽松等特点 ,为GB/T 17891— 1999 《优质稻谷》在粮食收购中的应用提供了依据

| Abstract: | A simplified method was developed to determinate amylose content in paddy rice. Scanner was used to collect the original image of the iodine colored solution and the hue of the image was then identified by the computer. There is a significant correlationship between the red value and amylose content. It is possible to predict the content of amylose by using this new test method without the tradilionally used spectrophotometer. With the advantage of low cost, rapidness, high efficiency, the method is hopefully to be used in rice trade process. |
