Pitaya with red heart is a common fruit with rich nutrition. Its special color "blood color" is rich in natural pigment-betanin, but it is not easy to decompose and metabolize, which often leads to the misunderstanding of "hematuria". At the same time, the fruit cracking rate of red pitaya is as high as 30% to 40% during planting. In order to reduce waste, three boys tried to extract natural pigment from it, and studied its efficacy and application to realize "turning waste into treasure".
Interest is the best teacher, and the process of inquiry is interesting. The three boys had a clear division of labor and tacit cooperation, and they also conducted experiments in the food safety and quality monitoring room of Zhejiang University. These results prove that beet pigment has certain antioxidant activity. Finally, they also conducted applied research and developed an antioxidant soft candy. It is reported that this kind of soft candy has applied for a national patent.
Those who can do more work, more work makes those who can do it.
Ye Yucheng, who is about to enter Hangzhou Senior High School, is the senior of He Yiwei and Zhu Yiyang. The establishment of this project has a lot to do with his own experience. Three years ago, Ye Yucheng, who had just entered the public welfare middle school, joined the DI (Creative Thinking Competition) with the encouragement of senior students, and entered the global invitational tournament all the way.
This experience has made him full of gains, and he is even more grateful to the seniors for their help. In senior three, he decided to continue the flame and spirit of this scientific and technological innovation. Therefore, he encouraged two junior students to join his team to study the pigment of pitaya. Now, two students are about to enter the second grade, and their grades are also very good. Repeated experiments and explorations enable them to continuously consolidate their scientific knowledge during the project.
Children's dreams cannot be separated from their parents' support. Zhu Yiyang's mother also came to the exhibition site to cheer for the children. When asked if she was worried that her children's grades would be affected by the competition, she said frankly: "I was worried before, but now I feel that there are more opportunities. Children mainly use their spare time to study and spare some spare time to do these meaningful scientific projects, which is very helpful for them to broaden their horizons. Taking part in such a contest, Yiyang may go further and further on the road of scientific inquiry. The child has now started to teach himself high school courses, and our parents will fully support his dreams. "
Like these children, the country needs talents like you.
