Defatted Yellow Mealworm (Tenebrio molitor) Meal – Wholesale Bulk Supply
Our defatted mealworm meal is crafted from carefully selected Tenebrio molitor larvae—the most extensively studied and commercially established insect protein species in the world. Harvested at optimal nutritional peak and processed through a proprietary low-temperature mechanical defatting system, our meal removes excess fat while preserving heat-sensitive bioactive compounds—including antimicrobial peptides, defensins, and chitin—and concentrates crude protein to levels that exceed premium fishmeal.
Yellow mealworms have long been recognized as a superior protein source, with larval protein content reaching 51% in whole form. Through our defatting process, we elevate this to 65–70% crude protein—a level that places our mealworm meal among the highest-quality protein concentrates available to the feed industry.
A Landmark Regulatory Milestone: In January 2024, AAFCO (Association of American Feed Control Officials) granted the first-ever US approval for defatted yellow mealworm protein for use in dog food. This historic authorization—following a two-year evaluation—officially opened the US pet food market to mealworm-based ingredients. Our product meets these AAFCO standards, positioning US feed manufacturers and pet food brands at the forefront of the insect protein revolution.

Science-Backed Performance – Proven Across Species
Aquaculture
Defatted mealworm meal has been extensively studied as a fishmeal replacement across multiple species:
- Rainbow Trout: Can effectively replace 100% of fishmeal in juvenile rainbow trout diets with positive effects on growth performance and nutrient retention. Studies confirm that high dietary inclusion of defatted mealworm meal supports growth, histological integrity, and overall health.
- Large Yellow Croaker: Dietary fishmeal replacement with mealworm meal supports growth performance, humoral immunity, and intestinal health.
- Spotted Seabass: Replacement of 5% of fishmeal promotes intestinal health and growth; replacement up to 15% shows no negative effects. Recommended replacement level for freshwater culture is not exceeding 7.31%.
- Pikeperch: Replacement level of 25% yielded the highest weight gain rate and specific growth rate with the lowest feed conversion ratio.
- Turbot: Defatted mealworm meal time-dependently influences growth and muscle texture, with studies evaluating replacement levels of up to 45% of dietary fishmeal protein.
- Chinese Mitten Crab: Defatted mealworm meal serves as an effective alternative protein source for juvenile crabs, supporting growth performance, intestinal health, and serum immune and antioxidant indices.
Poultry & Swine
For monogastric animals, mealworm larvae provide a high-quality protein and amino acid profile, making them a highly sustainable protein source for replacing soybean meal or fishmeal. The chitin content in the cuticle acts as an indigestible fiber with positive effects on the immune system.
