Cutting-edge technology helps the food safety. At this annual meeting, nearly 50 scientists and technicians conducted research results in a more intuitive oral report in a variety of technical topics such as food chemistry and biotechnology, food nutrition and health, new product technologies, food safety and testing. The exchange and sharing represents the latest academic research progress in the past year. On the morning of November 9, a sub-forum of “Food Grouping: Present and Future†was held by the School of Food Science and Engineering of Nanjing University of Finance and Economics. Many readers may not know what food grouping is. We only need to know that it is a brand new discipline. It uses advanced omics technology platforms and methodologies to study cutting-edge research in food safety and nutrition to improve our consumers. Welfare and health are enough. Zhang Heping, a professor at Inner Mongolia Agricultural University, said in his report "Application of Lactic Acid Bacteria in Human and Animal Health - Research Based on Microbial Genomics" that the currently developed probiotic lactic acid bacteria products are widely used in food, medical , animal husbandry and agriculture. At the meeting, new enzymes on genomics and its application in the oil industry, proteomics and metabolomics in functional food research, metallography in the field of grain, oil and food nutrition and safety, based on advanced functions The topic of the new method of food safety and accurate detection of nanomaterials was shared with the participants. What about the "food adulteration" that the people pay very much attention to? Researcher Chen Ying, deputy dean and chief engineer of the China Academy of Inspection and Quarantine, conducted an in-depth analysis of food grouping and explained various testing methods. Chen Ying said that authenticity is not unfamiliar to everyone, and the whole concept of food quality and safety has also been expanded. Food quality and safety is not only the quality and safety of daily life, but also the appearance quality, flavor quality, authenticity of ingredients, authenticity of origin and safety issues. In terms of authenticity, everyone’s attention to it has been particularly high for so many years.
At the moment, people are paying more and more attention to the authenticity of food. Why is the authenticity of food more and more fierce now? If the capital has a 50% profit, he will take risks. If there is a 300% profit, he will dare to commit any crime and even risk being "hanged". Therefore, food adulteration is not to say that China has it. This is a global issue. For example, New Zealand produces about 1,700 to 2,000 tons of Manuka honey every year, but globally, honey sold in the name of Manuka is more than 10,000 tons per year. The annual output of rice in Thailand is 18 to 22 million tons, and the export volume is 8 to 12 million tons. The rice exported to China accounts for 2% to 3% of its export volume, about 300,000 tons, but the market sales of fragrant rice reaches 1 million tons. There are also adulteration of chicken industry in Brazil, adulteration of dairy products in India and Pakistan, adulteration of beef products in Australia and South Africa, and adulteration of rice in South-East Asia...
Some investigations have been made on the identification of food authenticity. From the literature of 40 articles in the past 20 years, there are mainly six technologies in the identification of food authenticity: physical and chemical analysis technology, molecular biology technology, protein technology, artificial intelligence technology. Morphological analysis techniques and sensory analysis, etc. Now more is the use of a omics technology, the so-called omics technology is to combine these techniques to systematically study the authenticity of food. Genomics, proteomics, and metabolomics are well established. Applying some of the techniques of omics to the identification of authenticity may not be the basic research of omics in the true sense, but the use of some techniques of omics to make the authenticity of food.
Chen Ying said that genomics technology is used in authenticity identification. What kind of problems can it solve? It is our authenticity identification that can be detected from single species to multiple species, and from rigid detection to digital PCR. Genomics technologies include real-time fluorescent PCR technology, digital PCR technology, gene chip technology, DNA fingerprinting technology, gene barcode technology and second-generation sequencing technology. PCR-like technology, mainly used for the identification of plant-derived ingredients in cereals, plant starches, nuts, and condiments; identification of animal-derived ingredients in meat products and dairy products; on bird's nest, white fungus, agar, pig skin, egg white, etc. Identification of target ingredients and adulterants of high-value foods; identification of fruit components in fruit juice; identification of honey sources such as litchi, longan, artichoke, rape, vitex, jujube, alfalfa and sunflower. The use of nuclear magnetic resonance metabolomics, combined with chemometric analysis, can be used to successfully distinguish between olive oil and its adulterated edible oil.
Big data-based food omics (genomics, metabolomics, paper omics, proteomics, etc.), led by non-destructive rapid detection (intelligent bionic recognition, visual imaging, biosensing, etc.) will be The main development direction of future food authenticity identification technology.

Removable Oxygen Generator
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
With a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.
