Is hydrogenated soybean oil gluten free?

Yes, hydrogenated soybean oil is gluten-free.

Here's why:

* Soybean oil is naturally gluten-free. Gluten is a protein found in wheat, barley, and rye. Soybeans are a legume, not a grain, and therefore do not contain gluten.

* Hydrogenation is a process that changes the fat structure of the oil. It does not introduce gluten or any other ingredients from gluten-containing sources.

Important Note: While hydrogenated soybean oil itself is gluten-free, it's important to check the labels of any foods that contain it. Some food manufacturers may use ingredients that contain gluten in their products, even if the oil itself is gluten-free.
