Pteridium aquilinum is a kind of wild vegetable, which contains glucosinolates, and it is slightly bitter, but it is generally not very bitter, which is acceptable to most people. If Pteridium aquilinum tastes bitter, the following two reasons should be considered.

1. The reason of Pteridium aquilinum

Pteridium aquilinum in the mountains can be divided into sweet Pteridium aquilinum and bitter Pteridium aquilinum. Generally, we often eat sweet Pteridium aquilinum, which is not obvious in bitterness and fresh and tender in taste. The bitter bracken tastes bitter and difficult to remove, and many people find it difficult to accept this taste.

2. Pteridium aquilinum goes bad

Pteridium aquilinum tastes bitter. Pteridium aquilinum is rich in water and sugar, so its shelf life is not long, and it is easy to breed bacteria and rot. However, the deteriorated Pteridium aquilinum tastes very bitter.

If it is because of picking or buying bitter fern, this kind of bracken can still be eaten, and moderate consumption will not cause adverse effects on human body; If bracken is bitter due to decay, it should not be eaten any more, because it has produced a large number of microorganisms harmful to human body, which may cause physical discomfort after eating.
