Study finds coffee cup color affects bitter taste
According to foreign media reports, a new study has found that when people drink coffee, the color of the coffee cup will affect the feeling of bitterness, and the white coffee cup can deepen the body's feeling of bitterness and increase the bitterness of coffee.
In this study, the researchers reportedly asked subjects to drink coffee from white, transparent and blue coffee cups, and then recorded their feelings about the bitterness of the coffee.
The researchers found that subjects who used white coffee cups experienced "stronger" bitterness and lower sweetness than those who used transparent and blue coffee cups.
Psychologists believe that people generally associate color with taste, such as white and bitterness. The color of the coffee is in sharp contrast to the white coffee cup, so it highlights the bitterness. The use of transparent coffee cups can enhance the sweetness felt by users, while the use of blue coffee cups can enhance both bitterness and sweetness, so users will feel that the coffee is stronger.
The researchers suggest that the coffee industry should consider and adopt this finding because the color of coffee cups can affect consumers' multi-sensory experience of drinking coffee.
A previous study showed that if you put a cream dessert on a white plate, people would find it 10% sweeter and 15% more delicious than on a black plate.
