Is it possible to buy natural and pure Vanilla bean powder from the online marketplace? There are possibilities but chances are dim. The reason is readymade powder contains added preservatives and chemicals to retain the flavor and aroma of vanilla beans. These preservatives and chemicals are not good for the human health. Therefore, the best way to eat healthy food is to prepare it at home. Simply buy grade A or grade B vanilla beans from the marketplace, dry them in the natural sunlight for a few days and then grind them in a mortar and pestle or in a mixer grinder. In this way, you will get pure and natural product.
