The desiccant in fried food is iron powder, which is non-toxic. The reason for this is the following：

1, iron powder as a desiccant itself is not toxic.

2. The reaction principle of iron powder as desiccant is that iron reacts with oxygen and water in food packaging to generate X hydrated iron oxide.

3. As a desiccant, iron powder can prolong the shelf life of food by removing oxygen and moisture in food packaging.

4. The reaction product X iron oxide hydrate (the main component is iron oxide) is also non-toxic.
