Coconut flour is still considered to be the perfect alternative to wheat & few other traditional grain flours. Coconut flour is rich in protein & fiber along with being gluten-free & naturally grain-free. These unique characteristics (Rich in fiber, protein, gluten-free & grain free) makes it the best option for those who are on grain-free diets such as keto or paleo diet. Apart from that people suffering from celiac disease or who are allergised to wheat can use coconut flour as a best suitable alternative.
Coconut flour is derived from internal meat of the coconut. Milk is extracted from the meat of the coconut, resulting in leftovers of meat. These leftovers are dried down at very low-temperature & grinded fine to obtain flour. So, mainly there are two main reasons to sift coconut flour. One is due to improper grinding; uneven surfaced flour sifting becomes mandatory & second is due to its tendency to clump & dense nature it needs to be sifted.
