World Coffee Science Congress-the 26th World Coffee Science Congress results released

Coffee chemistry:

The research results of experts from various countries show that different processing methods and storage conditions have effects on the microbial and chemical composition of coffee. In the process of storage, lowering the storage temperature can better ensure the quality of coffee.

Professor Pochun Possion, a professor from Switzerland, briefly described how to keep coffee fresh in the coffee distribution system. The professor's research team used three methods to prove how coffee can better ensure the freshness of coffee in the process of distribution. The experimental study shows that the oxidation rate of coffee is different with different material packaging, and the quality and freshness of coffee are also different. the materials with high barrier and high oxygen permeability can protect the quality and freshness of coffee on the shelf. And a variety of new technologies are also gradually promoted and applied in the coffee industry, indicating that coffee research around the world is paying more and more attention to the application of high and new technology, and the research on coffee quality indicators is becoming more and more standardized, accurate and objective.

Agricultural aspect

1. Global warming has led to the reduction of coffee production and the intensification of diseases and insect pests, which is a fatal disaster for the coffee industry. The increase of carbon dioxide concentration and temperature will affect the photosynthesis and resistance to heat and drought of coffee. Therefore, the sustainable cultivation of coffee in the future, under the influence of global warming, the quality of coffee will be affected disastrously.

2. Studies on coffee rust, coffee anthracnose, leaf miner, coffee bark beetle and short body nematode.

Among them, Dr. VitorVarzea from the Portuguese Rust Research Center (CIFC) introduced the coffee rust control strategy of CIFC. Coffee rust is one of the most harmful coffee diseases in the world. at present, the prevention and control of coffee rust can only be controlled by copper-containing chemicals such as Bordeaux solution, but chemical control methods can only cure the symptoms and can not fundamentally protect coffee trees from rust. CIFC proposed from a long time ago that rust-resistant varieties should be selected through breeding to fundamentally control coffee rust. At present, the Yunnan variety Catimor is a rust-resistant variety introduced from CIFC and widely popularized.

74 top scientists, experts and scholars in the coffee industry gave a report at the conference. A total of 278 papers from 35 countries were collected, including coffee breeding, agronomy, biology, chemistry, physiology and processing. " On December 8, the Organizing Committee of the 26th World Coffee Science Congress held a press conference in Kunming to introduce the research achievements of the Congress.

The World Coffee Science Conference is the highest standard event in the world coffee industry, which represents the highest voice of the industry, and is also known as the "Olympics" of the world coffee industry. During the meeting, scientists focused on coffee consumption and health, the role of coffee chemical components in activity, odor, flavor, coffee cultivation, genomics, sustainable development, pathology, breeding and pest and coffee quality control.
