According to Gourmet World, plum beans contain saponin and phytohemagglutinin, which are toxic to the human body. However, after blanching, these harmful substances will be removed, so they can be dried directly in the sun.

In addition, sun-drying plum beans is also one of the ways to preserve plum beans.

Through the sun-drying process, the moisture in the plum beans will be removed, thereby extending the shelf life of the plum beans.

However, it should be noted that during the process of drying plum beans, attention must be paid to hygiene and quality to avoid contamination and deterioration.

At the same time, after drying the plum beans, they need to be sealed and stored to prevent moisture and oxidation.

Therefore, it is okay to dry the plum beans directly in the sun without blanching them, but you need to pay attention to hygiene and quality to ensure that the dried plum beans are safe to eat.
