  I started the development, development and production of ice cream, ice cream and sorbet in 1997. If you develop new products, you have to try them. I am 75 years old this year, and I am still relatively old, because I am the chief engineer and try to eat more. During the research and development process, I have to eat at least 40 or 50 pieces per day.

  【Explanation】Crispy tube, big milk nugget, ice cream "cool"......counting the cold drinks products that I have participated in the research and development and successfully listed Eat it. One of the most popular ice cream brands, "Shuang", has been selling well for more than 20 years, and has accumulated production and sales of about 12 billion pieces so far. Liu Qingnian told reporters that the research and development of these products are inseparable from the steps of research, ingredients, evaluation, and debugging. Trying to eat and tasting is the key.

  The first bite is called the head tone on the tip of the tongue. If the head tone is adjusted, it depends on whether there is any other taste. After the head tone is adjusted, it is middle tone. The middle note is to stay in the oral cavity for a period of time to see how good this variety is. My experience is relatively rich. Based on its milk content, I can basically taste the range in which the protein content in it floats.

  [Commentary] The research and development team led by Liu Qingnian has a total of 6 people, composed of three generations of old, middle and young. I'm dealing with cold drinks every day, how does 75-year-old Liu Qingnian keep healthy?

  Trying to eat has a (certain) effect on the body, but I usually like to drink black tea and hot black tea. In this case, if I drink a cup of hot black tea immediately after the test, it will have a regulating effect on the body, plus I usually pay attention to the maintenance of the body, which means exercising, like walking fast, jogging.

  【Explanation】Having taken root in the cold beverage industry for more than 20 years, Liu Qingnian has also witnessed changes in the living standards and consumption concepts of the general public. Liu Qingnian said that China's cold beverage market is showing a blooming situation, and people's purchasing power is also increasing. In the future, he will continue to work hard to develop more "explosion" ice cream, so that people can enjoy a hint of coolness in the hot summer.
