Harmless extraction enhances the value of the tea industry The deep processing of high-quality agricultural products helps rural revitalization in an all-round way

The harmless extraction of tea can improve the quality of tea purification products, reduce environmental pollution and energy consumption, and greatly increase the added value
of tea.
This is undoubtedly of great practical significance
for tea growers, who have been plagued by pesticide residues.
How to enhance the value of traditional tea with advanced extraction technology? How to organically combine with aerospace health and organize modern agricultural production? Sheng Lin, founder of the Green Medical Fund Project of Tsinghua University Education Foundation and founder of China Academy of Aerospace Nutrition, gave his answer
.

Shenglin has long been committed to the research in the field of green medical care and the exploration of the integrated platform of medical imaging industry, education and research, and has successively served as the leader
of many national fund projects such as the Innovation Fund of the Ministry of Science and Technology, the Development Fund of the Ministry of Industry and Information Technology, and the Beijing Natural Science Foundation.
His team's initial focus on tea-related technology stemmed from the over-promotion of tea culture in China in the past few years, which led to the abnormal development of tea cultivation
.

Sheng Lin believes that due to the consumption side's deliberate pursuit of the so-called concepts of "before the Ming Dynasty" and "before the rain", some tea growers have adopted some "seedling-fueled" planting methods in order to pursue economic benefits, which not only makes the tea lose its original value, but also unreasonable planting methods lead to tea pesticide residues exceeding the standard, so that a large number of tea cannot be exported to earn foreign exchange
.

"China is a big country in tea cultivation, but the entire tea industry is relatively backward
.
Through the empowerment of technological applications such as EGCG extraction, the entire tea industry in China can be upgraded to the level
of scientific and technological pharmaceutical platforms.
This can not only give birth to a new trillion-level industry, but also explore a new path
for the development of tea cultivation and other traditional Chinese medicine products.
When talking about the opportunities that EGCG extraction brings to traditional tea cultivation, Sheng Lin said
.

After starting research in related fields, Shenglin team initially carried out in-depth cooperation with well-known research institutions and universities in the United States, and then promoted the research and development
of EGCG-related products in some hospitals and medical institutions in the United Nations.
After 10 years of research, the Shenglin team officially submitted a patent for harmless extraction of high-purity EGCG in China in 2017, and finally obtained authorization
in 2022.

In Sheng Lin's view, EGCG-related products have created a new field of protein regulation for disease treatment, which is not only the cultural expression of traditional Chinese medicine, but also an effective exploration
of the international development direction of traditional Chinese medicine at the forefront of modern biomedical technology.
As explained in Cancer Biology, the most authoritative book in the field of tumor biology, drug intervention targets protein molecules to regulate their functions, and functional proteins play an important role in truly regulating the body, which can provide a theoretical basis and research and development model
for the development of a large number of botanical drugs (traditional Chinese medicine) in the future.

At present, Shenglin team uses microfluidic chip technology combined with traditional drug purification technology to extract EGCG harmlessly
.
Microfluidic chip technology is easy to combine with mass spectrometry, electrophoresis and other technologies, which can integrate sample preparation, pretreatment, separation and detection, which greatly improves the utilization efficiency of raw materials, reduces pollution and energy consumption
.

In view of the different application scenarios and indications, EGCG products currently have a variety of production processes
such as aqueous solvents, microcapsule products, and atomization products.
For example: the size of the atomized particles of EGCG atomization products determines the effect on the upper or lower respiratory tract, and different combinations determine whether the antiviral effect is better or the anti-inflammatory effect is better, while EGCG microcapsule products are dosage forms
that reduce the digestion and absorption of EGCG in the stomach by regulating the intestinal flora.

At present, relying on the traceability platform of aerospace health products jointly built by the China Society of Health Information and Health Big Data of the National Health Commission and the National Institute of Health and Medical Big Data of Hainan University, the work carried out by the Shenglin team includes the development of aerospace biological products through carrying and space-ground control, the detection and analysis of high-quality food and drug products including aerospace products and the establishment of relevant standards, the construction of space-grade high-quality products, and the use of blockchain technology and space remote sensing, electronic traceability code, Stamps and other traceability means to manage the whole process of aerospace traceability products, and carry out real-world data research
based on traceability feedback.

Just a few days ago, they cooperated with the School of Pharmacy of Peking University to send a batch of medicinal and food homologous products into space, including anti-aging masks, anti-radiation foods and other products
.
New products such as space coconut milk, developed by their team, will also be available
in the near future.
