Antioxidant activity of Fuding White Tea

With the improvement of people's living standards, people pay more and more attention to health. The word "antioxidant" is mentioned frequently, but do you really know about it?

The essence of the so-called antioxidant is to scavenge free radicals in the body. Free radicals are constantly produced in the human body due to continuous contact with the outside world, including respiration (oxidation), external pollution, radiation and other factors.

Smoking, air pollution, water pollution, radiation, pesticides, high stress in life, excessive exercise, and so on, can increase the concentration of free radicals, which is called oxidative stress. The greater the oxidation pressure, the higher the concentration of free radicals in the body.

The body's antioxidants are not only self-synthesized, but also supplied by food. However, with the development of society, there are more and more factors that increase the concentration of free radicals in daily life, and their own antioxidant system is facing the crisis of underuse. At this time, we usually need to rely on outside food to provide antioxidants.

The importance of antioxidation

More and more studies have shown that antioxidation is an important step in preventing aging and many health problems. If excessive oxidative free radicals can be eliminated, many diseases caused by free radicals and aging-related diseases can be prevented.

When it comes to antioxidant and anti-aging, we have to mention the cosmetic luxury Chanel No. 10 lotion for naturally or temporarily sensitive skin, which Chanel launched this year.

The core ingredient of the formula is the triple efficacy of Baihao Silver Needle (Silver Needle), the most rare and precious variety of white tea. Only select the bud top of the tender leaves, pick it by hand, take ten days, and dry it on the shelf with the ancient method. Chanel Research Department extracts extraordinarily active ingredients rich in theanine and polyphenols. Biological tests in vitro show that it has triple effects:

1 soothing: regulate the production of neurotrophic factors (NGF synthesis reduced by 75%) and restore sensory perception.

2 calming: block free radicals and protect skin from oxidative pressure.

3 tenacity: promote three key proteins that affect keratinocyte differentiation (keratin, silk polymeric protein, aristolochia protein), consolidate skin barrier function.

So what is the scientific analysis of the antioxidant activity of white tea?

Lin Zhi, a researcher from Tea Research Institute of Chinese Academy of Agricultural Sciences, made a preliminary exploration on the antioxidant activity of Fuding white tea.

The experiment mainly used iron ion reduction method (FRAP method), scavenging DPPH free radical activity, APTS free radical scavenging activity and oxygen free radical scavenging activity to detect the antioxidant activity of white tea.

Research summary

1: on the whole, the antioxidant activity of Baihao silver needle was significantly higher than that of white peony and Shoumei, but there was no significant difference between white peony and Shoumei.

2: there was no significant difference in antioxidant activity among Baihao silver needle, white peony and Shoumei in different years.

What is the relationship between the mass concentration of the main chemical components in white tea soup and its antioxidant activity?

The law of tea soup is different from that of dry tea, which is related to the brewing process and methods. However, some rules of antioxidant activity can be obtained from the composition analysis of tea.

Research summary

The antioxidant activity of white tea soup is related to the total amount of tea polyphenols, catechins, flavonoids and organic acids.

Therefore, whether you love beauty or pursue health, you should often drink Fuding white tea. Of course, Bai Hao silver needle is an excellent choice.
