Electronic tongue analysis of taste characteristics of functional beverages

In 2016, the Beijing Olympic Forest Park's national fitness activity “Light Pig Run” attracted the attention of the public. Now more and more people are willing to invest time and money into sports and health. After the exercise, the human body not only needs to replenish water, but also needs to replenish minerals in order to make up for the lost energy in time. For this reason, functional beverages have gradually become the best companion for people's sports. With the surge of the national fitness boom, functional beverage consumption It also grew rapidly.

The survey found that the functional beverage brands on the market are diverse and have different functions. How to choose the most suitable beverage according to your own situation has become a problem that plagues everyone. At present, people can only find the beverages that suit their needs, such as Shennong taste the herbs in order. In order to solve the confusion of consumers when buying, we chose the nutrient water and scream of Nongfu Spring, the Gatorade of Pepsi, and the five functional drinks (lemon flavor) of Coca-Cola Hydro Music and Robust Pulse. Using INSENT's TS-5000Z taste analysis system to evaluate taste, analyze the relationship between taste and formula, and provide some guidance for people to choose.

The sample is not processed, poured directly into a dedicated sample cup, set up the test procedure, and start the test. Cycle test three times, using the instrument's own software to display data results. Based on the taste index of artificial saliva (the tasteless points of artificial saliva are all 0), it was found that sour, sweet and salty tastes are the main taste characteristics of such functional drinks. The salty taste comes from the taste of the electrolyte component added to the beverage. Different brands of beverages have significant differences in taste and each has its own characteristics. The pulsation has a prominent sour taste compared to other functional beverages. The sour taste value is 23.57, the relatively weak sweet and salty taste, the values ​​are below the tasteless point; the water music is similar to the taste of Gatorade, and the water is moving. The bitterness, astringency and salty taste are larger than that of Gatorade. It shows that the electrolyte content is slightly higher than that of Gatorade. The taste is more complicated and rich. The saltiness of Nongfu Spring is lower than the tasteless point. The taste is lower than the water and the Gatorade has about 2 scales of 3.02.

It can be seen that the biggest feature of Gade, water and screams in functional drinks is that they are rich in electrolytes and have a salty taste when consumed. The pulsating taste is the most special, and the prominent acidity makes the taste more intense. The biggest characteristic of the pulsating taste of lime; Nongfu Spring Vitamin Water is balanced and soft in these five brands. By analyzing the taste characteristics of functional beverages, we can be more targeted and purposeful when purchasing drinks, so that our body is balanced from the inside out.
