Using intelligent whiteness tester to check flour quality
One of the quality symbols of flour is pink, which is often used to test the quality of flour. It is used to determine the accuracy of the flour by comparing the standard sample Liu Zhao with the Peke method (powdered board and comparing the color drum star with the naked eye). . Since this method is a sensory appraisal, it is easy to see a phenomenon that looks high and one looks low. Appraised reviews can only be black, white, high, low, or slightly higher, lower, etc. There are no figures. In this way, the inspection work was difficult and inconvenient. Some inspectors also use ash to determine flour, but reliable data on pink color are often not available depending on the size of the ash.

How to use some of the more advanced scientific instruments to replace the currently unsatisfactory flour quality appraisal method has given food inspection workers a new topic. Smart whiteness tester is proposed in this situation. The reflectance of light in milk and skin in wheat is not the same. The reflectance of endosperm is much stronger than that of skin. The amount of light reflected from flour is a measure of pinkness or whiteness. Whiteness is expressed in terms of reflectance, which is the amount of light reflected by an object and a pure white surface (whose reflectance is 100%). The ratio of the amount of reflected light is expressed as a percentage.
Intelligent whiteness measuring instrument according to different quality of wheat, to produce the law of different whiteness value of the flour, that is, the whiteness of white wheat flour is higher than red wheat, soft wheat is higher than hard wheat, white wheat and soft wheat The number of flours in wheat is added together to give the base value of the whiteness value of the flour, combined with the effect of the flour thickness on the whiteness value, and the base number of the whiteness value is adjusted to obtain the theoretical whiteness of the wheat flour. degree.
