Which nutrition is better, fresh tremella or dried tremella?

Everyone knows that tremella has a high nutritional value, so tremella is more and more favored by the public. However, when people buy tremella, they often choose some so-called "fresh tremella".

In fact, the "fresh tremella" circulating in the market is processed, non-toxic and can be cooked and eaten directly. In fact, the real fresh tremella is different, different from ordinary tremella.

On the one hand, from the production process, fresh tremella is not processed, while ordinary tremella is processed and dried in multiple stages.

On the other hand, fresh tremella contains porphyrin photosensitive substances, which will be distributed to human epidermal cells with blood circulation after eating fresh tremella. Exposure at this time may lead to solar dermatitis, skin redness, itching, pain, bright red papules and blisters. Porphyrin photosensitive substances are also easily absorbed by throat mucosa, leading to symptoms such as throat edema, general malaise, runny nose, tears, fatigue and shortness of breath. Ordinary tremella contains no porphyrin photosensitive substance, which is harmless and beneficial to human body.
