Because colour greatly influences a consumer’s preference and choice in food products, maintaining precise consistency is vital. Food colour directly correlates with the biological, chemical and physical changes food undergoes during growth, maturation, post-harvest and processing. Measuring colour in food is one of the fastest and most accurate forms of quality control because it’s simpler and quicker and applies indirectly to other critical product characteristics.
Food colour is vital in the food and grocery business because it conveys flavor, quality and freshness — three vital factors customers consider before buying. Because colour is a consumer’s primary product evaluation tool pre-purchase, it requires the most attention during processing, from measuring ingredients to production to the final packaging. Processed foods dominate grocery store shelves, and one inconsistency in manufacturing can lead to a detrimental domino effect for an entire brand.
Food processing companies use colour measurement devices to evaluate a broad range of fresh and processed food products, including fruits, vegetables, meats, dairy products, spices and flavorings, sugar, grains and cereals, syrups and more. These devices offer the food processing industry’s most subjective and consistent quality control methods.
Because reflected light determines a material’s colour, a food’s appearance can change based on the quality of light, amount of light and observer’s viewing angle, indicating the importance of food placement on grocery store shelves.
The two most common devices for food colour measurement are colorimeters and spectrophotometers. Colorimeters quantify colour by measuring the three primary colour components — red, green and blue — while spectrophotometers measure the actual colour within the human visible light wavelength.
The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
