What is coconut endosperm?

Coconut endosperm is the tissue found inside the coconut fruit, commonly referred to as coconut meat or copra. This endosperm is rich in fats, proteins, and carbohydrates and provides a significant energy source. In the immature coconut, the endosperm is liquid, known as coconut water, which gradually solidifies into a white, fleshy substance as the coconut matures. This endosperm is consumed fresh or dried and is used in various culinary applications, such as cooking, baking, and making coconut milk.
