Editor's Note: With the improvement of living standards, people are no longer satisfied with food, food, and food safety as they become a new life style and pursuit goal. In particular, in China, a country where food is the basis of the people's minds, if we can invent some tools to detect whether the packaged foods are out of date, whether they are deteriorating, and ensure that consumers feel comfortable eating, such a huge market, who will not be tempted? In this field, some countries abroad have undoubtedly walked in front of us and have set a good example for us.
Ben Wang compiled reports: Ubonrat Siripatarawan, a researcher at Thailand's National Chulalongkorn University in Bangkok, Thailand, invented a fast, reliable, inexpensive technology for diagnosing pathogens in packaged foods. Before the food companies distributed their products to retailers, the technology could determine whether their products were contaminated. When an electronic nose is connected to a mathematical model, it can quickly and accurately detect the number of bacteria in the packaged vegetables.
Siripatarawan was first measured in a packet of alfalfa sprouts. The alfalfa sprouts were selected for testing because it is often eaten raw in salads in the form of fresh unprocessed vegetables. Therefore it has more health risks.
As a result of the research, Siripatarawan intends to replace the traditional method of population counting. The traditional method requires 24 hours to detect the number of pathogens. After using the electronic nose, it takes only 10 to 15 minutes. Mathematical models can convert data collected from electronic noses into the type and quantity of pathogens specified, including the number and nature of the pathogens. The electronic nose consists of 12 series of metal oxide electronic sensors used to detect changes in the gas mixture emitted by biochemical products. For each vegetable, different mathematical models can be designed to detect specific bacteria.
Siripatarawan hopes to use this technology in the detection of pathogens in meat products in 2005, and the technology also has great potential for daily necessities.
Thirty years ago, a Japanese professor invented the electronic nose. More than ten years ago, electronic noses were used to detect the fragrance of perfumes and wines, but this time it was a completely new use for them.
Thailand Chulalongkorn University Introduction:
Chulalongkorn University (Thailand) is the first institution of higher learning established in the history of Thailand. It is ranked among the top ten universities in Asia and is the number one public university in Thailand. Facing the ever-changing needs of the society, Chulalongkorn University is adhering to the trend and has trained a large number of outstanding talents for his country and people. After a century of growth and development, Chulalongkorn University has made considerable progress in improving the quality of students, especially in teaching their professional knowledge and training professional skills.
Chulalongkorn University has 18 departments and schools, colleges and research institutes engaged in teaching and related activities. The school has about 2,950 faculty members and 27,236 students. It provides 30 international courses and 344 majors in the four major fields of science and technology, sociology, health science and humanities. The solid strength of the undergraduate teaching of Chulalongkorn University has earned him wide acclaim. In the near future, they have focused the development of school teaching on scientific research. Chulalongkorn University is seen as a pioneer in Thai higher education in many ways. It is often closely watched by peers and the public, guiding the direction of the development of higher education in the country and the direction of the development of certain special professions.
The leadership role of Chulalongkorn University in Thai higher education also depends on how he adapts to the changing needs of society. In addition to education, Chulalongkorn University has also won respect from the community in many other aspects, especially his contributions in advancing the modernization of Thailandâ€™s modernization process.
