Silkworm Pupa Powder

Why does silkworm pupa powder have a high protein content?

Silkworm pupa powder has a high protein content because silkworm pupae naturally accumulate large amounts of proteins during their developmental stage to support metamorphosis. These intrinsic proteins are retained through processing, resulting in a protein-rich final ingredient.

Functional Foods:

Silkworm pupa powder provides a concentrated source of high-quality proteins, essential amino acids, and natural lipids, making it suitable for use in energy bars, baked goods, meal replacement powders, flavored snacks, and instant blends. It enhances the overall protein profile, enriches texture, and supports diverse functional food formulations.

Dietary / Nutritional Supplement Ingredients:

Silkworm pupa powder offers a high-protein, nutrient-dense raw material for supplement applications. It can be used in protein powders, capsules, tablets, and blended nutritional formulations. Its balanced amino acid composition supports the development of protein-enriched supplement products and contributes to diversified ingredient systems.

Feed Industry：

Silkworm pupa powder serves as an efficient protein ingredient for aquatic, poultry, and livestock feed. It improves the protein ratio in compound feed and supports stable formulation performance.

Pet Nutrition:

Silkworm pupa powder provides concentrated animal-based proteins suitable for pet food and pet treats. It helps enrich the nutritional composition and supports the development of high-protein pet formulations.

High Protein Content：

Silkworm pupa powder contains a high level of complete proteins with a balanced essential amino acid profile, offering a richer amino acid spectrum compared to common plant-based protein sources.

High Processing Compatibility：

Defatted silkworm pupa powder typically contains ≤5% fat and appears as a light yellowish-brown fine powder with mild odor. It shows good dispersibility and integrates well into feed and food formulations without significantly affecting the original texture.

Q1: What is silkworm pupa powder used for?

A: Silkworm pupa powder is used as a nutrient-rich, high-protein ingredient in aquaculture, livestock, and pet feed to support growth performance and improve feed conversion efficiency. It is also applied in functional foods, nutritional supplements, and seasonings for protein enrichment and formulation enhancement.

Q2: Is silkworm pupa powder good for skin?

A: Silkworm pupa powder has potential skin benefits, primarily due to its rich content of essential amino acids, which serve as the building blocks of skin proteins. It also contains unsaturated fatty acids such as omega-3 that help nourish the skin, support moisture retention, and contribute to maintaining a healthy skin barrier.

Q3: Can silkworm pupa powder be defatted?

A: Yes, silkworm pupa powder can be defatted using methods such as mechanical pressing or solvent extraction. Defatting typically reduces the fat content from around 20–30% to ≤5% and increases the protein proportion, resulting in a more concentrated, stable ingredient suitable for feed, functional foods, and nutritional supplement formulations that require lower-fat profiles.
