Vacuum-Packed Silkworm Pupae Bulk Wholesale Supplier
Vacuum-packed silkworm pupae have rapidly emerged as one of the most sought-after edible insect products in global B2B markets, prized for their exceptional protein density, extended shelf life, and versatility across food manufacturing, aquaculture feed, and exotic pet nutrition sectors. As consumer interest in sustainable protein sources accelerates worldwide, silkworm pupae — the preserved chrysalis stage of Bombyx mori — offer processors and distributors a shelf-stable, nutrient-rich ingredient that requires no cold chain for transport. Our vacuum-sealed packaging technology removes over 99% of residual oxygen, effectively inhibiting oxidative degradation and microbial growth, ensuring that each batch retains optimal color, aroma, and nutritional integrity from our facility to your warehouse. With consistent quality control, HACCP-certified processing lines, and flexible MOQ tiers designed for both mid-scale distributors and large industrial buyers, we are positioned as a reliable long-term bulk wholesale partner for vacuum-packed silkworm pupae across Asia, Europe, and North America.
What are Vacuum-Packed Silkworm Pupae?
Silkworm pupae are the third life-cycle stage of Bombyx mori (Linnaeus, 1758), a domesticated moth in the family Bombycidae. After silk thread is harvested from the cocoon, the enclosed pupa — measuring approximately 20–25 mm in length and 10–12 mm in diameter — is collected, cleaned, thermally processed, and hermetically sealed under vacuum. The resulting vacuum-packed silkworm pupae product is classified as a processed edible insect ingredient, recognized under EU Novel Food Regulation (EU) 2015/2283 and widely traded across Asian commodity markets.
Vacuum-Packed Silkworm Pupae Breeding and Rearing Process
Our silkworm pupae are sourced exclusively from controlled sericulture farms where Bombyx mori larvae are reared on certified, pesticide-free mulberry leaves (Morus alba) under regulated environmental conditions of 24–28°C and 70–80% relative humidity. Larval development spans 25–30 days through five instars before cocooning. Post-silk-reeling, pupae are immediately sorted by size uniformity (≥18 mm), blanched at 95°C for 8 minutes to ensure pathogen inactivation, then vacuum-sealed in multi-layer barrier pouches with an oxygen transmission rate below 0.5 cc/m²/day.
Vacuum-Packed Silkworm Pupae Biological Specifications
Each unit of processed vacuum-packed silkworm pupae delivers the following verified parameters on a dry matter basis: crude protein content of 48–55%, crude fat content of 28–33% (predominantly unsaturated fatty acids including linolenic acid at ≥18%), moisture content ≤8% post-vacuum sealing, and ash content of 3.5–4.5%. Individual pupa weight ranges from 1.8 g to 2.5 g fresh weight. Shelf life under ambient storage (≤25°C, away from direct light) is 18 months for vacuum-sealed pouches and 24 months for nitrogen-flushed bulk packaging formats of 5 kg, 10 kg, and 25 kg.
