    Colorful potato pots, dealcoholized wine, selenium-rich instant tea powder.


    At the same time, major universities in Shaanxi have seized this opportunity, actively transformed scientific research results, and competed to bring "high-tech" delicious food to the people's table
    .


    "Move" the lab to the field

    Recently, in the laboratory of Northwest A&F University, potatoes of red, purple, black, yellow and other colors were "lying neatly" on the table, waiting to be made into specimens
    .


    Hybridizing and screening out these colorful potatoes is not easy
    .


    In order to promote colored potatoes, in 2017, when Chen Qin went to Zhenba County to help, he brought some colored potato seeds and planted them locally
    .


    In 2018, when Du Haotian, a graduate student who was still studying at Northwest A & F University, went to Zhenba County with the school to investigate, he thought that the colorful potatoes here would definitely be favored by the market and decided to do a big job
    .


    Just do
    it.


    After returning to campus with a colorful potato pot, Du Haotian was
    "red".


    Today, Du Haotian has graduated
    .


    Eat the specialty fruit "dry and squeeze clean"

    The brewed wine is poured into the instrument, and as the instrument runs at high speed, the dealcoholized wine slowly flows out from the other end of the instrument.


    On July 27, in the laboratory of Shaanxi Normal University, Wang Fei, a first-year student majoring in food science and engineering, was conducting a wine dealcoholization experiment
    .


    How to make full use of local fruits in Shaanxi is the direction
    that Wang Xiaoyu's team from the College of Food Engineering and Nutritional Science of Shaanxi Normal University has been exploring.


    Wine is a "regular" on the table, but many people minimize alcohol intake for health reasons
    .


    Team member Chen Tongguo said that after the grapes are made into wine, the discarded grape skins can also be processed into delicious grape rose cakes
    .


    In March this year, Wang Xiaoyu's team's grape processing technology and industrialization application won the "First Prize for Outstanding Scientific and Technological Research Achievements in Shaanxi Colleges and Universities"
    .


    In the Engineering Research Center of the Ministry of Education for the High Value Utilization of Western Fruits of Shaanxi Normal University, in addition to grapes, the team also develops the whole fruit utilization technology
    of local fruits such as apples, kiwifruit, and red dates.


    12 patented technologies "eaten into the stomach"

    In the late summer, stroll through the tea garden base of Xinglong Town, Pingli County, and the endless "tea sea" is pleasing to the eye
    .
    However, such a beautiful scenery once upset local tea farmers
    .

    It turns out that the "Ming tea" and "rain tea" in the rainy season from before and after the Qingming Dynasty to the valley rain season can often sell at a good price, while summer tea and autumn tea are "money-losing goods"
    in the eyes of tea farmers.
    Yue Tianli, a professor at the School of Food Science and Engineering of Northwest University, after investigating and understanding this situation in Ankang City, was determined to use scientific and technological means to turn "money-losing goods" into "fragrant food"
    .

    "Although summer tea and autumn tea are not sold at a high price, their nutritional composition is almost the same as that of high-priced spring tea
    .
    " Yue Tianli said
    .
    Therefore, "making a fuss" with the nutritional composition of tea has become the main direction
    of Yue Tianli's team.

    Chinese tea drinking method is mainly to soak the original tea leaves, and the tea brewed by the delicate spring tea has a warm and fresh taste, so it is very popular
    with the masses.
    However, Feng Kewei of Yue Tianli's team found in experiments that when tea leaves are extracted and separated to make instant tea powder, it is difficult to distinguish between
    spring tea, summer tea and autumn tea in taste.
    "Many foreigners have the habit of brewing tea powder, so we decided to process the poorly sold summer and autumn tea into instant tea powder for export to help tea farmers increase their income
    .
    " Feng Kewei said
    .

    Ankang is rich in selenium-rich tea, how to make selenium-rich instant tea powder without losing its flavor and nutrients as much as possible? After many tests, Yue Tianli's team found that the continuous extraction technology of low-temperature oxygen-blocking and low-temperature oxygen-blocking drying technology can effectively reduce the loss of tea aroma and active ingredients, and the leaching and concentration process developed by the team can also maximize the retention of tea polyphenols and other nutrients in tea
    .
    "In order to do a good job, we applied for 12 patented technologies
    .
    " Yue Tian Li said
    with a smile.

    Kung Fu pays off
    .
    As soon as the selenium-rich instant tea powder products were listed, they were recognized and praised
    by overseas markets.
    "The tea powder sales enterprises we cooperate with began to accept overseas orders in 2019, and the export volume in 2020 reached more than 79 million yuan
    .
    At present, the products represented by selenium-rich instant tea powder developed by us have been exported to more than 10 countries in Europe, the Middle East, Southeast Asia and other regions, with a cumulative export income of 13.
    6753 million US dollars
    .
    Talking about the scientific research results of his team, Yue Tianli was very pleased
    .
