Application of DDC Technology Day | Chromatometer in Quality Control of Feed Flavoring Agent Products
ABSTRACT: Chromatic aberration meter is an instrument to quantify color phenomena and establish color standards. It is one of the effective means to further improve the appearance of products by using color aberration meter to control the color quality of products. Colorimeter is widely used in textile printing and dyeing, paint, leather manufacturing and other industrial fields. The measurement of color and color difference is very important, and it is one of the important indicators of product quality in printing and dyeing enterprises. CIE1976L*a*b* Uniform Color Space, also known as CIELAB Uniform Color Space, has been published by the International Lighting Commission and has been widely used in the color matching of surface pigments such as coatings, building materials and paints. Among them, L* is the luminosity coordinate, representing the brightness of the color; a* b* is the color coordinate, representing the hue and saturation of the color.
Key words: chromatograph, feed flavoring agent, quality control
At present, the role of feed flavoring agents in improving feed intake has been recognized by more and more people. But it is worth noting that the volatility of aromatic release is the stability of condiments.  For the evaluation of the quality of feed flavoring agents, the commonly used methods in factories are sensory comparison method and simulation or production test method.  At present, when purchasing feed flavoring agents, they will smell and look at the appearance, which mainly consists of several quality control indicators such as color, granularity and so on. The judgment of colour and lustre is mostly made by comparing the production sample with the standard sample with the eye under appropriate conditions. This judgment result is limited by the subjective conditions of the analysts, and is prone to missed and mistaken detection . The evaluation of color difference by eyes is influenced by subjective factors and other factors, and it is easy to cause dissent and disputes between manufacturers and customers. Instrumental measurement is a popular method in the world today. At present, in the international market, especially in the United States and Europe, instruments are mainly used to objectively evaluate the color and color difference in order to quantify the value of color difference.
