The formation of golden flower is mainly caused by two factors: temperature and humidity.
The main producing areas of Liubao tea are concentrated in Wuzhou area, where the geographical conditions are superior and the climate is mild and humid. 10 to March of the following year is very suitable for the growth and reproduction of eurotium cristatum. After being suppressed, Liubao tea can naturally form golden flowers without too much intervention and regular placement. In this process, "Eurotium cristatum" quickly became the dominant strain and participated in the formation of color, aroma and taste substances in Liubao tea. The secret of Jinhua Liubao tea is that it is delicious and mellow.
Tea lovers who have a little knowledge of Liubao tea know that the later storage and transformation of Liubao tea need the participation of corresponding microorganisms, among which Ascomycetes cristata is a rare and precious beneficial bacteria, which will only appear under certain conditions.
While growing in tea, Eurotium cristatum will secrete some enzymes, which will further transform the substances in tea through the action of enzymes, thus improving the taste, aroma and taste of tea. For example, cellulase can promote the transformation of coarse and old fibers in tea into soluble sugars and enhance the taste of tea soup; Polyphenol oxidase can catalyze the oxidation of catechin into oxides such as thearubigins and theaflavins, and optimize the soup color. At the same time, with the oxidation of catechins, amino acids and other substances in tea are also oxidized to produce various aroma compounds, thus making tea more fragrant.
According to the corresponding research reports of Hunan Agricultural University and Northwest A&F University, the various substances produced by Cephalosporium coronatum catalyzing tea transformation have strong functions of lowering blood fat, lowering blood pressure, regulating human glucose metabolism and metabolism, and enhancing human immunity. Cephalosporium can make the health care effect of tea more obvious. Therefore, the "golden flower" on Liubao tea is not only drinkable, but also beneficial to human body.
The "golden flower" on Liubao tea needs to be formed under specific factors and conditions. First of all, in terms of raw materials, it is required that the tea cyanine of Liubao tea is coarse and old and contains rich substances. In addition, in the process of processing tea cyanine, it is required that the rich contents in tea leaves overflow fully, which is beneficial to the growth of Eurotium cristatum, which forms "golden flower".
Secondly, and most importantly, in the process of making Liubao tea, it is required that either Cephalosporium coronatum is on the tea body or Cephalosporium coronatum is attached to the tea. And this is also the most difficult, because microorganisms are extremely small, invisible to the naked eye, difficult to manipulate artificially, and accidents only happen under extremely coincidental circumstances.
Furthermore, when storing tea products, the temperature of tea products is required to be cold outside and hot inside, and the humidity is dry outside and wet inside. Only in this environment can cysticercus grow.
As mentioned above, raw materials, strains and storage environment are indispensable for the growth of Eurotium cristatum, so Liubao "Golden Flower" is extremely rare.
Liubao tea has many health care functions, such as protecting the liver, reducing blood fat, resisting oxidation, regulating immunity, preventing and treating type II diabetes, lowering blood pressure, etc., which we love. How about "Jinhua" Liubao tea? Does it have other functions?
Some experts have found that Jinhua in different fermentation periods can significantly improve the activity of protease, promote the enzymatic hydrolysis of starch, pepsin and trypsin on protein, facilitate the digestion and absorption of starch and protein, and improve the intestinal function of human body; In addition, it can also inhibit the degradation and absorption of fat by the digestive system.
Therefore, Jinhua Liubao tea has stronger functions of promoting digestion, reducing blood fat, dissolving fat and regulating sugar metabolism compared with ordinary Liubao tea. Drinking "Jinhua" Liubao tea can better nourish the stomach, lose weight and reduce fat.
