It is reported that Brazilian research institutes are taking a step forward in the successful development of caffeine-free coffee beans

Caffeine contained in coffee, green tea, energy drinks, etc. has a stimulating effect by stimulating the central nervous system, and when ingested, it reduces drowsiness and fatigue, but excessive intake adversely affects the body. A research team at Instituto Agronômico de Campinas (IAC) , an agricultural research institute in Brazil, has been conducting research on decaffeinated Arabica coffee for 20 years.

Moderate intake of caffeine has been suggested to not only eliminate drowsiness, but also reduce the risk of obesity and diabetes , andreduce the negative effects on cognitive performance . However, excessive intake of caffeine not only causes dizziness, increased heart rate, increased blood pressure, sleep disturbance, diarrhea, nausea, etc. due to stimulation of the central nervous system, but also severe heart failure and kidney failure due to caffeine poisoning. It has been pointed out that it can cause

One 8 ounce cup of coffee contains about 95 mg of caffeine. The Dietary Guidelines for Americans recommends 3 to 5 cups, or about 400 mg, of caffeine per day for healthy adults.

The IAC research team breeded Arabica coffee beans containing about 1.2% caffeine per grain to achieve a maximum caffeine content of 0.10%, which is considered 'decaffeinated'.

The research team used an embryo bank in the research facility to cross Ethiopian coffee beans with low caffeine content and coffee beans with normal caffeine content, resulting in a caffeine content of 0.10% to 0.30%. created a new breed between The research team then cloned

the embryos present in the somatic cells of the genetically modified coffee beans to select individuals with up to 0.10% caffeine content and potential for commercial production. Been going for 20 years.

Julio Cesar Mistro of IAC said, ``The purpose of this project is to enable Brazilian coffee producers to produce new varieties of genetically caffeine-free Arabica coffee,'' said the research results. The results so far are promising for the future.'

According to the research team, the clones of decaffeinated coffee beans developed at IAC have been planted in various regions of Brazil, but since it usually takes two to three years to harvest coffee beans, It will still take years to collect coffee beans from the tree and test them.

According to a survey by the National Coffee Association (NCA), decaffeinated coffee consumption accounts for about 10% of coffee consumption in the United States. When IAC's research on decaffeinated coffee beans is successful and shipments start, it is believed that it will be able to acquire a niche position in major coffee consumption areas such as Europe and the United States.
