The Cordyceps flowers are picked from fresh flower and dried in sun, the color is golden yellow, uniform in shape, even in spore head, with the smell of fungus, no peculiar smell, no sulfur fumigation. Cordyceps flower color fading is because the color in Cordyceps flower is mainly composed of carotenoids, which will decompose when exposed to light, so the authentic Cordyceps flower will turn white in the sun. Which is the same phenomenon in the stronger light. Those that don't change color in the sun are basically smoked.

Cordyceps flower cultivation: the culture medium is bottled firstly and sterilized at high temperature for 12 hours, then the bacterial strain is made, and then lighting, ventilation, watering and temperature control are carried out, until picking, drying, packaging and then keep out of the sun.
