Color measurement of products made from tomatoes

Tomatoes are bred and selected for traits that are important to their specific growing, harvesting, processing and consumption requirements and also dictate their flavors, textures and other characteristics. Color, an important measurement parameter for tomato products, is closely linked to quality and taste.

In fact, the U.S. Department of Agriculture has clear indices that are used to classify processed tomato products around the world. HunterLab was the first company to receive USDA approval for the instrumental evaluation of tomato color. Our valued customers include Heinz, Cargill, ConAgra Foods, Campbell’s, Pacific Coast Producers, Kagome, Ingomar Packing and Del Monte.

Common tomato products that require accurate color control include: Tomato paste, tomato puree, tomato sauce, ketchup, tomato juice

When measuring the color of these products, it is important that the selected instrument meets the requirements for instrumental color measurement of tomato products and complies with the standards for classifying these products. HunterLab is the only manufacturer to offer the ColorFlex EZ Tomato device with matching firmware and tile for calibration.

For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
