Can I add this oat fibre to baking and cooking? — Siberian fiber Oat Stop-Appetite 170 g

Yes, this product is designed to be used in cooking. The product description mentions adding it to porridge, baking, and homemade bread to raise the fibre content of the meal. You can stir a spoonful into your morning oatmeal, or add it to the dough for bread, muffins, or pancakes. Because the fibre absorbs water, you'll likely need to add a little more liquid to your recipe to keep the dough or batter at the right consistency. The fibre will also make the final product slightly denser, which is fine for most baked goods.

When you bake with it, the fibre doesn't lose its properties — it still provides the bulk and gel-forming effect. However, the effect on appetite may be less direct than taking it before a meal, because the fibre is now part of the food. That's still a good way to increase your daily fibre intake. If you're new to baking with fibre, start with a small amount — for example, a tablespoon per half-kilo of flour — and adjust the liquid as needed. You can also sprinkle it over salads or mix it into soups, though the source doesn't specifically mention those uses, they are common ways to add fibre to a meal.

Just remember that fibre needs water to work properly, so make sure you drink enough fluids throughout the day, especially if you're adding it to dry baked goods.
