Container Colour, Perception, and Behavior
Research also indicates that container colour plays an important role in the perception of complex foods. A 2013 study found that a fraisier dessert with primary yellow, white, and red tones and a vacherin glace with light pink, white, and cream colours were rated as significantly sweeter, more flavorful, and more appetizing when presented on a white plate versus a black plate.3 A raspberry and vanilla fraicheur with more brown tones, however, was perceived as sweeter, more intense, and more appetizing on a black plate.
But container colour doesn’t only affect how food tastes—it can actually impact how much food we eat. In a study published in Appetite, participants were presented with identical amounts of popcorn and chocolate chips on red, blue, or white plates.4 After correcting for personal preference, researchers found that participants ate less popcorn and chocolate when using a red plate. The contrast between the food and plate did not appear to influence behavior; it was something about the colour red that altered consumptive habits. Nicola Bruno, author of the study and psychology researcher at the University of Parma in Italy, said, “I expected to find the results related to differences in colour intensity, but they did not. It’s really related to the colour red.”5 Except, perhaps, when the food in question is red. Previous research found that test subjects in a buffet line served themselves 22% more pasta with marina sauce when using red plates versus white plates.6
Using Colour Analysis to Enhance Food and Beverage Containers
Understanding how use container colour to optimize appeal of foods and beverages may significantly enhance consumer interest in and use of your products, particularly if you manufacture goods designed to be consumed directly from the container in which it is sold. Colour analysis can help you develop and produce food packaging that increases the palatability of your product and encourages consumption. When a colour scheme has been developed, integrating spectrophotometric instrumentation in the production line ensures continuous monitoring to ensure consistent, accurate pigmentation of your container.
Plastic Containers: If you are working with plastic packaging, colour analysis can be used to measure raw material such as plastic pellets, liquid pigments, and powders prior to extrusion to ensure that you are starting with the right ingredients. Integrating spectrophotometers throughout the manufacturing process, from initial staging to evaluation of final container form, allows you maximum control and quality assurance. Spectrophotometric instrumentation with integrated height measurement guarantees accurate analysis of even heavily textured plastics that present challenges to traditional measuring methodologies.
Paper Containers: When it comes to paper containers, spectrophotometric analysis is an ideal option for maintaining consistent pigmentation. The diverse range of geometries available provides precise, accurate colour quantification regardless of surface texture, including high-gloss finishes, and can pass/fail pigmentation according to your set tolerance range. In-line spectrophotometric instrumentation from HunterLab allows for unique dye pump connectivity to automate colour control in paper production.
HunterLab’s innovative spectrophotometers offer clear, objective colour analysis to assure quality, repeatability, and efficiency of container pigmentation.
