What citrus is Daidai?

Daidai is a citrus, that came from the Himalaya district through China in an older time. It is grown world wide. People are more familiar with the citrus being known as a sour orange in Europe. The ripe yellow fruit turns to green in spring again and it’s called 回青橙, Kaiseitou, which means the citrus that turns green.

Daidai in Hagi is harvested from the middle of September to December. The trees bear fruits one after another, and they say such productiveness is the sign of succession and its a favorable lucky tree. Therefore, it is used as a New Year’s decoration wishing for prosperity and goes down from generation to generation.

The third function

Main ingredients
function
Citric acid
When it’s absorbed, it goes through TCA cycle, that works with the meabolism.
★Effect of citric acid- It makes the metabolism cycle to be returned to normal and it removes the lactic acid.
Active acid
In the active acid function, except for the condensation of protein, there’s another function of the conbination of plain amino acid. Plain amino acid is the acid that goes through the brain. Any substance should go through the BBB(blood brain barrier)to go inside of the brain, it is necessary for amino acid to be condensed.So the active acid assists this function.
The relationship between active acid and citric acid
When a person tastes the sourness, the citric acid inside of the body reinforces the activity of active acid. When the nutrition goes through BBB(blood brain barrier) to go into the brain, and the citric acid inside of the body leans to under ph4.0, the citric acid affects the active acid and that reinforces the metabolism. Also, when the citric acid is absorbed into the body, inside of the biological cell, the citric acid turns into active acid.
★Effects of active acid ⇒Brain metabolism and brain circulation works very well and it increases the learning ability and memory. Also, there’s academic proof of it having a good effect for Alzheimer’s disease.

The function of our food is very useful for lowering the risk of diseases or trouble from lifestyle-related illness. But, it’s very important to gain as much as possible from eating natural foods. Once the sense of taste is recognized by the brain it gives the necessary order for promoting internal circulation so we can maintain our health. Making good use of natural foods without additives is the best way for the human body to stay balanced and safe.
