The role of color measuring instrument

According to research on color psychology, proper colors will leave a good impression on people, increase appetite, such as red gives a sweet and mature impression; orange gives a sweet, pleasant, healthy, cheerful and vibrant impression; yellow represents bright , hope and harvest; green makes people feel safe, comfortable and fresh; blue gives a refreshing, quiet impression; purple represents gentleness and mystery; white represents clean, fresh, clear, and black means mature. There is a direct relationship between food color and freshness and quality, and to a certain extent, the color of food also reflects the nutrition and function of food. Therefore, there is a “selective color and food, and food has a proper way”. Say.

People have always used the sensory evaluation methods to assess the quality of food color, fragrance, taste, etc., in order to better quantify the color, ensure product quality, prevent food corruption, pollution, and increase product attraction. Force and the food industry introduced colorimetry and spectrophotometry, which are two main methods. Through the combination with software, the color measurement, color matching, color formulation, and color quality control of products from the laboratory to the factory are realized.

Color measurement instruments can be used for food color management, agricultural product, seafood and meat growth check or grade classification, determine the freshness of raw meat, research preservation methods, or conduct consumer preferences surveys or product development. Visual appeal is far more important than the sense of smell in the retail world where refrigerated, frozen, boxed, dried and plastically packaged food is displayed behind glass.

Colorimetry is a method of quantifying the three primary colors of light seen by the human eye. By examining the correlation between the product color difference and the sensory evaluation value, the effect of human factors on the measurement result is removed, making the determination of the color more objective, guiding the addition of color components to the food or beverage formulation, improving the “color attractiveness”, and regulating the food "How well cooked" and so on provide a credible basis for product development and quality control. The spectrophotometer mainly relies on measuring the spectral power distribution of the object reflection or the reflectivity characteristic of the object itself, and then according to the spectral measurement data, the tristimulus value of the object under various standard light sources and standard illumination bodies can be accurately calculated. By combining color formulation software and color matching software packages, portable and benchtop spectrophotometers can be used in laboratory color control systems to achieve a wide range of color control from research labs to plant sites. These color data software can achieve unprecedented color quality control, making color detection and control easier.

Role: To escort the food industry, bake delicious foods, solve the problems of non-homogeneous fruit processing, send fresh foods to homes, and provide solutions for the meat processing industry.

Color measurement is an emerging science involving optics, visual psychology and other disciplines. The continuous development of optics, electronic technology and optoelectronic technology, as well as the extensive use of electronic computers, gave rise to the development of various colorimetric instruments. At present, spectrophotometers and colorimeters are widely used by domestic and foreign laboratories, research institutes, and companies. With the increase of consumer demand for food quality, color measuring instruments will surely help enterprises establish objective standards, judge product colors, guide product development and production practices, promote industrial production standardization, and scientifically manage the entire food industry. Bigger effect.
