Terminology for Mealworm Flour
While commonly called mealworm flour, this product is also known as Tenebrio molitor powder or Tenebrio molitor flour, after the species of beetle it comes from. Broader terms include insect flour, insect powder, or entomoflour. In the EU, regulations may specify 'dried yellow mealworm (Tenebrio molitor larva) powder'. The chosen name can depend on the target market, region, and processing method.
Nutritional Benefits of Mealworm Flour
Mealworm flour is a highly nutritious ingredient, offering complete protein with all nine essential amino acids. It typically contains over 50% protein by dry weight and is a good source of healthy fats, including oleic and linoleic acids. Essential vitamins and minerals such as iron, zinc, magnesium, potassium, and B vitamins (including B12) are also present. Additionally, the chitin from the mealworm exoskeleton provides dietary fiber beneficial for gut health.
Culinary Applications and Use Cases
With a mild, nutty, and slightly earthy flavor, mealworm flour is a versatile ingredient. It's primarily used to enhance the nutritional value of foods rather than as a direct substitute for traditional flours.
