The color of the coffee cup affects the taste. Scientist: White cups make coffee more bitter

Using a white coffee cup will make people feel that the bitter taste of coffee is stronger.

Another example of the saying that "people are visual animals". A recently published research paper shows that the same coffee in different color coffee cups can make people drink different flavors. Among them, the use of white coffee cups will make people feel that coffee is more bitter and less sweet, while using blue coffee cups will make people feel stronger.

In fact, it is not uncommon that color affects taste. Studies have shown that if you drink hot chocolate, cream-colored cups will increase its sweetness and aroma. The best use of this theory may be in the field of dieting and weight loss: blue makes people lose appetite, and the use of blue cutlery and decoration is more conducive to dieting.

Do you want stronger coffee? Please use a blue coffee cup

Besides cream, sugar and milk, do you know what else can change the taste of coffee? The answer is: the color of the coffee cup. It sounds unscientific, but it does have a scientific basis, as confirmed by an article published in the journal Flavour in November 2014.

The study was led by George Van Dorn, a lecturer in psychology at the Commonwealth University of Australia, who conducted two experiments to see if the color of coffee cups affected consumers' judgment of the taste of lattes. In the experiment, the researchers asked subjects to drink coffee from white, transparent and blue coffee cups, and then recorded their feelings about the bitterness of the coffee.

The results showed that the color of coffee cups greatly affected the subjects' judgment of coffee taste: subjects who used white coffee cups felt lower sweetness and stronger bitterness than transparent and blue coffee cups. The blue coffee cup enhanced both bitterness and sweetness, making the subjects think the coffee was stronger.

"our research confirms that the color of coffee cups does affect people's sensory experience of coffee," Dorne said. "the significance of this result is that cafes, baristas and even pottery manufacturers should face up to this problem. maybe the color of the cup can affect whether consumers become regular customers or not.

Color affects taste, and blue helps you lose weight

According to the Medical Daily (Medical Daily), there have been a number of studies such as "the judgment of food quality may be affected by the characteristics of food containers." A 2013 paper published in the Journal of sensory Research (Journal of Sensory Studies) looked at the question of what color cups make hot chocolate taste better. The results showed that although in fact, the sweetness and aroma of hot drinks did not change with the color of the cup, the subjects did believe that cream-colored cups improved the sweetness and aroma of hot chocolate.

According to the Life Times, people's sensory abilities will decline if they can't see the color of the food. A study by the University of Washington in the United States shows that once the color of the drink is changed, it is difficult for most people to recognize it correctly. Without looking at the color, "only 70% of people can taste grape-flavored drinks, 30% of people can distinguish cherry-flavored drinks, and 15% of people can taste citric acid."

If you make good use of the effect of color on taste, it will have an unexpected effect. Red can give people a warm, festive and peaceful feeling, yellow can make people feel warm and comfortable, both can increase appetite, and the combination of red and yellow can make people unwittingly eat a few more mouthfuls, said Leatrice Eisman, author of Color goes with the Heart. Similarly, Takao Sakamoto, author of the Japanese Journal of Color Psychology, believes that blue represents serenity and calmness, produces a quiet effect, and gives a potential hint that people can't eat. If you play blue light in the refrigerator, it will make people less want to eat and will help you go on a diet.
