With the continuous development of the tea culture industry, the popularity of tea beverages in the tea industry is also increasing. The color of tea beverages represents the quality of tea beverages to a large extent, and Caipu Technology's transmission liquid Spectrophotometer has been applied in the color detection of tea beverages.
During the processing of tea beverages, the pH value and heat treatment have a great influence on the color difference of tea beverages, and the differences and differences in the processing process will cause certain color differences in the finished tea beverages. This requires distinguishing the color difference of different finished tea beverages to ensure the quality of tea beverages.
The transmission liquid Spectrophotometer CS-810 adopts the internationally accepted D/8 (integrating sphere diffuse illumination, 8° observation angle) SCI/SCE compatible illumination observation conditions, and ETC real-time calibration technology, among which ETC real-time calibration technology (Every Test Calibration ) is that the instrument calibrates the system hardware and software for each measurement. This technology fundamentally solves the long-term measurement stability and data drift problems of color measuring instruments. CS-810 has a number of national invention patents in this technology. Eliminates the subjectivity of visual colorimetry, providing greater sensitivity and repeatability. At the same time, the instrument can be used through the connection of PC and color management software, which is convenient for enterprise quality monitoring and color data management. It can digitize the user's color management, compare color differences, generate test reports, provide a variety of color space measurement data, and customize the customer's color management work. Meet customers' high requirements for color quality.
The following introduces how to measure the color difference of tea beverages by CS-810.
Step 1: Install the instrument, connect the instrument to the computer, turn on the instrument, perform black and white calibration, and prepare the standard sample and sample of the tea beverage to be tested;
Step 2: Open the sample chamber, put the tea beverage standard sample in and start the test;
Step 3: After the standard sample test is completed, take the standard sample out of the sample chamber, put the sample in, and start the test. Be careful not to let other artificial factors affect the test results;
Step 4: After setting various parameters, the test data can be obtained;
The actual test results are very satisfying to the customer. Through the test data, it can be seen intuitively that the liquid transmission Spectrophotometer satisfies the customer's requirements in the detection of the color difference of tea beverages.
