Manufacturers in Food Processing Industries and popular food manufacturing giants make use of natural and artificial dyes to produce color consistent and high-quality food products.  These ingredients are manufactured using various natural means such as fruits, vegetable, and spices. Maintaining the similar colors using natural ingredients throughout the production process is not an easy task because all ingredients have different color, taste, flavor and texture. Hence it is necessary to maintain the exact colors using artificial colorants. For example, keeping the Red color of tomato ketchup is difficult to maintain if artificial colors are not used because every tomato has a different tone of red color and hence give different output.  Therefore, manufacturers make use of Red colored, flavored dye to maintain the color consistency of ketchup throughout the production process.  These colorants are added to the products by the means of aromatizing process to remove the flavor of the colors so that it cannot hamper the taste of actual food products.

Another issue that arises with the natural food dyes is the natural color. These colors can’t be similar every time hence, making use of artificial ingredients is essential to maintain the quality and hygiene of the products. With the increasing importance of color measurement in food processing industries, it is necessary to measure the color of the ingredients using highly efficient portable spectrophotometers.

Testronix Instrument offers very useful portable spectrophotometers namely TP 800 and TP 810 to measure the color consistency of solid and liquid food ingredients. These instruments are highly effective to measure the color with 100% accuracy.
