摘要
通过用420nm、560nm、620nm三种波长测定中间制品(清汁、粗糖浆、清糖浆)的色值(°st)及白砂糖产品的色值(IU),并对其进行关联度的分析。结果表明,三种波长中,560nm波长测得的色值与白砂糖产品色值的关联度最大;3种中间制品中,清汁的色值与白砂糖产品色值的关联度最大。
The color values of semi-products （including clarified juice, syrup and purified syrup） and granulated white sugar were determined at 420 nm, 560 nm and 620 nm wavelength respectively, and then the correlation degree between the color of granulated white sugar and those of the three semi-products was studied. The resulted showed that the correlation degree of the color value between granulated white sugar and semi-products was the highest at 560 nm. Compared with the other two semi-products, the effect of clarified juice color value on granulated white sugar color value was the strongest.
