The ancient language cloud, Pu'er full of land, the terrace is down, the blend is secondary, the ancient tea is excellent, the ancient pure peak, the silver frost is visible, and the golden flowers are difficult to find. It has been shown that the probability of golden flowers in Pu'er tea is extremely low, so it is not possible to excessively pursue the long golden flowers of Pu'er tea.
Although it is said that pu'er tea golden flowers can not be sought, but it is still necessary to learn to distinguish between golden flowers and aspergillus flavus, in case the aspergillus aflex as a golden flower, the body can not eat ah!
1. What is a golden flower?
Golden flower, scientific name is Crown Fungus, is an enzyme fungus that is beneficial to humans. Its role is to produce an enzyme to help transform the proteins, starches, and polyphenols in tea into substances that are beneficial to the human body. The more golden flowers, the sweeter and smoother the taste, and the brighter the soup color is. Its growth and development requires a specific environment and a specific material basis, and under natural conditions, it is only occasionally found in tea, ganoderma lucidum and precious Chinese herbal medicines.
Second, what is Aspergillus aflex?
Aspergillus aflatophyllus, also known as Aspergillus aflatophyllus, Aflatophyllus aflatogenes, etc., is a fungus that is harmful to the human body. Aspergillus aflatophyllus has low requirements for external conditions, is widely distributed, and is easily produced in most animal and plant products in humid and hot environments. Often bred in the case of wet warehouses, it mainly survives in a humid and warm environment, grows on the nutrition of tea, and survives by spore reproduction after the end of the life cycle.
Third, how to distinguish between golden flower or aspergillus aflex?
1. Appearance differences:
Golden flower: exists in the interior of tea bricks, tea lumps, tea cakes, tea leaves occasionally have a small amount of distribution on the surface, and the flower body is clear, and the interface between flowers is clear. It is golden yellow, full of round granules, without hyphae, and there are no traces of other bacteria around it.
Aspergillus flavus: generally distributed on the surface or horns of the tea leaves, the bacterium is dry, irregular in shape, filamentous or powdery distribution, and the interface is not clear, the color is not pure yellow, and there are yellow-green or gray-green, with hyphae.
2. Odor difference:
Golden Flower: Tea leaves with golden flowers smell obvious tea aroma and fungal aroma, whether it is dry tea or tea soup, which is a very comfortable taste.
Aspergillus flavus: Tea contaminated with Aspergillus aflex will be covered with its tea aroma, and there will be a musty smell that will also carry other odors, pungent and choking.
3. Difference in feel:
Golden flower: Tea leaves with golden flowers, the golden flowers are attached tightly, and it is not easy to fall off when rubbed by hand. The tea strips are clear, the leaves are stretched after brewing, the leaf shape is complete, and it has a certain strength and elasticity to the touch.
Aspergillus aflatophyllus: tea contaminated with Aspergillus aflatogenes, mold attachment is not tight, easy to fall by hand rubbing, and with a damp and sticky feeling, in places where the flora is serious, tea leaves will form lumps, it is not easy to disperse when brewing, and tea leaves are very fragile to touch.
4. Differences in tea soup:
Golden flower: when brewing, it shows a normal soup color, clear and transparent, and the tea soup is sweet, thick, moist, resistant to brewing, with chen xiang and fungal fragrance, no musty smell and other peculiar smells.
Aspergillus aflatogenes: Tea soup contaminated with Aspergillus aflatogenes is carbon black or brownish black, cloudy and sticky, and there will be no obvious improvement after several bubbles, with a choking smell, and even disgusting.
Golden flower is harmless to the human body, while Aspergillus aflex is harmful to the human body, and there are similarities between the two, which can be easily distinguished by the above methods, and it is really not safe to find experts to identify. Therefore, in life, we should carefully distinguish, choose carefully, and do not blindly taste and drink to avoid serious consequences. Buying tea can be without golden flowers, but it must not be tea contaminated with Aspergillus aflex.
