- Application examples:

• Blind test of smell and taste of tea aroma and tea tasting
• Perfume Product Reviews

1. Blind test of smell and taste of tea aroma and tea tasting

In order to verify the accuracy of judging subjects' preferences through emotions, four kinds of tea were prepared. The test procedure was set as 0 to 9 seconds for subjects to chat with each other without touching the tea soup, 10 to 19 seconds for smelling the tea aroma, and 20 to 30 seconds for tasting. For tea, after the test is completed, write down the feeling of smelling the tea and drinking the tea, and then compare the results of the brain wave analysis.

The following is the content of the company’s industry-university cooperation cases:

The first tea: T9~T10 The mood does not change when you start sniffing, but the positive mood value increases during the sniffing process, indicating that you like the aroma of tea;

The mood rises when tea tasting starts from T19 to T20, and the mood value continues to be positive during the process, which means that the person likes the tea after tasting it.

The second type of tea: T9~T10, the mood did not change when I started sniffing, but dropped to -4 during the sniff, indicating that I have opinions about the tea aroma;

When tea tasting starts from T19 to T20, the mood value suddenly rises to +5, indicating that you like the tea very much.

The third type of tea: The mood value rises when you start sniffing from T9 to T10, indicating that you like the aroma of tea;

When you start tasting tea from T19 to T20, the emotional value remains negative, indicating that you have no opinion on the aroma of the tea (the analysis result is that if the emotional value changes greatly for one second, it will return to positive later).

If it is normal, it is an error value and can be ignored).

The fourth type of tea: T9~T10, the mood value rises when you start sniffing, but drops again during the sniff, indicating that you don’t like the tea aroma;

The emotional value from T19 to T20 remains positive, indicating that you like the tea very much after tasting it.

After the test, all the emotional judgment results of each person's brain waves were compared with the feelings of smelling tea and drinking tea. It showed that the accuracy of emotional judgment of liking was as high as 98%.

2. Perfume product evaluation

Two fragrance essential oils are prepared for this test, hoping to know which fragrance the subjects prefer. The test procedure is set as the subjects chat with each other without touching the fragrance oils in the first few seconds, start to smell the fragrance in the middle, and stop later. Smell and check the results of the brainwave analysis after the test is completed.

This is the test result of one of the subjects (the pre- and post-tests are different aromas):

It can be found that when the subject stopped sniffing at T85, the emotional changes in the "pre-test" on the left were not much different from those during the previous sniffing, but the emotional changes in the "post-test" on the right were still the same after stopping sniffing. Maintaining the same height when sniffing means that the scent tested in the "post-test" is more liked by the subjects and can bring about long-term positive emotions.
