The color difference of soy sauce affects the quality of soy sauce to a certain extent. Therefore, it is very necessary to detect the color difference of soy sauce. The following is an example to introduce the color difference detection of soy sauce.
A customer is a large-scale soy sauce production enterprise. The production base covers an area of about 3,000 mu and is a comprehensive production base for condiments.
Enterprises have very high requirements on the quality of soy sauce. The general way to identify the color difference of soy sauce is to pour the standard sample and test sample soy sauce into white plates, and see the difference with the naked eye under the fluorescent lamp. Because the human eye's color difference is greatly affected by ambient light, containers, etc., and different individuals' color discrimination is also very different, so it is impossible to accurately distinguish the color difference of soy sauce. Due to the limited threshold of the human eye, small differences cannot Therefore, the current method of human eye discrimination cannot meet the high quality requirements of enterprises for soy sauce.
Liquid Transmission Spectrophotometer CS-810 is a high-performance spectrometer specially designed to measure liquid transmittance, absorbance, concentration, chromaticity and other parameters. The resolution of the instrument reaches 0.0001, the standard deviation of transmittance is within 0.08%, and the chromaticity value: ΔE*ab 0.015. Eliminates the subjectivity of visual colorimetry, providing greater sensitivity and repeatability. It fully meets the requirements of soy sauce production enterprises for color difference measurement of soy sauce.
In addition to measuring liquid transmission, the instrument also includes APHA/PtCo (APHA/Platinum Cobalt) and Gardner (Gardner Index) color scales for products such as resins, solvents, acids, perfumes and varnishes; , white oil, kerosene, lubricating oil and paraffin oil measurement Saybolt (Saibert) color scale.
We use the liquid transmission Spectrophotometer CS-810 to accurately detect the color difference of soy sauce.
After turning on the instrument, professionally conduct black and white calibration, and start testing after the black and white calibration is completed;
Open the software, when the instrument tests the sample, the standard sample should be tested first, and then the sample should be tested;
After the test is completed, accurate measurement data can be obtained;
Through the test, according to the actual measurement data, customers can intuitively see the differences between different soy sauce samples.
Liquid transmission Spectrophotometer CS-810 can overcome the shortcomings of naked eye identification, and can well meet customers' high requirements for soy sauce quality.
