Supplier comparisonMealworm and black soldier flyUpdated October 2026
QUICK ANSWERSino Crown differs from most insect protein powder manufacturers in three ways. It processes both mealworm and black soldier fly protein, it mills its powders finely (120 to 200 mesh), and it sells from trial lots to full containers out of Qingdao, China. Large European and Southeast Asian producers offer local supply and bigger contract volumes. The better fit depends on your market, volume and import paperwork.

How insect protein powder manufacturers differ by region
Insect protein powder comes from a small group of producers, and they are built very differently. Region, species and scale decide most of what a buyer experiences: price, lead time, import paperwork and how flexible the order size can be.
| Supplier type | Examples and focus | What it means for a buyer |
| European industrial black soldier fly producers | Innovafeed in France and Protix in the Netherlands run large industrial plants. Innovafeed's Nesle site is ramping toward 15,000 tonnes of protein a year, and Protix produces 17,000 to 18,000 tonnes of live larvae a year, according to The Fish Site. | Local supply inside the EU and large contract volumes. Producers themselves say energy and labour costs are higher in Europe, which shapes pricing. |
| Southeast Asian black soldier fly producers | Entobel in Vietnam makes 300 to 400 tonnes of insect meal a month, and AgFunderNews reported in March 2026 that Protix is shifting its growth focus to Southeast Asia. | Lower operating costs and rising volumes, but a single species. Shipping and import paperwork need to be checked for each destination. |
| North American producers | EnviroFlight, part of Darling Ingredients, supplies black soldier fly ingredients for animal feed and pet food. | A natural fit for US buyers, where AAFCO ingredient definitions and FDA rules apply. |
| Mealworm specialists | Tebrio in Spain focuses on Tenebrio molitor. Ÿnsect, once the best-known mealworm company, entered judicial liquidation in December 2025. | Mealworm powder supply is thin, so supplier continuity matters as much as price. |
| Chinese processors, including Sino Crown | Sino Crown is based in Qingdao and processes both mealworm and black soldier fly into powders and oils. | Sea freight from Qingdao, a 200 kg trial batch and private-label packs listed on its product pages. |
The sector has been through a hard shakeout. AgFunderNews reported that Ÿnsect failed and Agronutris entered a safeguard plan, while Innovafeed and Entobel kept scaling up. For buyers, a supplier's staying power is now part of any manufacturer comparison.
Where Sino Crown differs from other manufacturers
Sino Crown is a Qingdao-based processor that turns yellow mealworm (Tenebrio molitor) and black soldier fly (Hermetia illucens) larvae into whole dried products, powders, defatted protein powders and oils. Six differences stand out when it is set next to other manufacturers.
| Area | Sino Crown | Many other manufacturers |
| Species | Both yellow mealworm and black soldier fly, sold as dried mealworm powder, black soldier fly meal, defatted protein powders and oils. | Many large plants are built around one species, so a buyer who needs both usually needs two suppliers. |
| Protein grade | The defatted mealworm protein powder is listed at roughly 70 to 73 percent crude protein, and the defatted black soldier fly protein powder at about 57 to 58 percent. | Defatted black soldier fly meal from other producers sits in the same range. Entobel lists 57 to 58 percent for its H-Meal, so headline protein rarely separates suppliers. |
| Processing and particle size | Defatting by mechanical cold pressing, stated to use no chemical solvents, followed by physical milling to 120 to 200 mesh (125 to 75 µm). The defatted black soldier fly grade is listed at 200 mesh. | Many published specification tables list protein, fat, fibre, ash and moisture but not particle size, so buyers have to ask for it. |
| Rearing diet | States that its larvae are reared on a 100 percent plant-based diet. | Substrates vary from producer to producer, and the declaration is not always on the product page. |
| Order size and packing | 200 kg trial batch, 20GP and 40HQ container loads, 15 kg and 25 kg paper bags with a PE liner, and 1, 5 and 10 kg private-label foil bags. | Industrial producers plan around contract volumes, so trial lots and small private-label packs are not always on offer. |
| Scale | A factory of more than 4,700 square metres and container-scale shipments, covered below. | The industrial leaders work at thousands of tonnes a year. |
Why fine milling matters
Mesh counts the openings in a sieve per inch, so a higher number means a finer powder. A 120-mesh powder passes particles of about 125 µm, and a 200-mesh powder passes about 75 µm. Insect powder contains chitin, the hard shell material, and coarse chitin particles wear on puffing and extrusion equipment. Sino Crown states that its fine grind reduces equipment wear in puffing plants and keeps the powder suspended in liquid recipes such as cat food strips and aquatic feeds.
Defatting works in the same direction. BioMar's trials, reported by The Fish Site in December 2025, found that defatted insect meals gave better nutrient stability and extrusion than full-fat meals. That is why defatted, finely milled grades are the ones pet food and aquafeed formulators ask about first.
A plant-based diet and what it means for compliance
Under EU rules, farmed insects may be fed only on products of non-animal origin or a short list of Category 3 animal products, and manure and catering waste are banned (Regulation 142/2011). A 100 percent plant-based diet sits fully inside that rule and keeps mammal-derived ingredients out of the larvae's feed.
The trade-off is the story. Some European producers build their brand on turning food by-products into protein, a model that EU rules limit. A plant-based diet is the simpler route for compliance, and it gives up the waste-to-protein message. Sino Crown does not publish its feed formulation, so a written substrate declaration is the document to ask for.
Scale is the honest difference
Innovafeed, Protix and Entobel operate at thousands of tonnes a year. Sino Crown's factory covers more than 4,700 square metres, and its published shipment notes for 2025 include about 6 tonnes of mealworm protein powder to Austria, 18 tonnes of black soldier fly protein powder to Germany and about 15 tonnes of mealworm products to France.
That makes Sino Crown a container-scale supplier, not a contract supplier for several thousand tonnes. For pet food brands, aquafeed R&D teams and distributors, that is often the size they need.
What GMP+ and FDA registration prove, and what they do not
Sino Crown states that it holds GMP+ FSA certification and U.S. FDA registration. The two credentials are often grouped together, but they answer different questions. GMP+ FSA (Feed Safety Assurance) is a feed safety scheme run by GMP+ International, with audits by independent certification bodies, and it covers hazard control, traceability and monitoring. FDA facility registration is a notification: facilities that make or hold animal food for the U.S. market register with FDA, and FDA does not issue a certificate of registration.
| Credential | What it shows | What it does not show |
| GMP+ FSA certification | An independent audit found the site's feed safety system meets the scheme's requirements. | That a specific batch meets your specification, or that the product may be sold in a given country for a given animal. |
| FDA facility registration | The facility is on file with FDA as one that makes or holds animal food for the U.S. market. | An FDA review or approval of the product, the recipe or the ingredient. |
| Ingredient and use rules | Whether a species and a use are allowed in a market, such as the EU species list or an AAFCO ingredient definition. | Anything about a particular supplier's plant or paperwork. |
BEFORE YOU ORDERA certificate does not replace market rules. In the EU, processed protein from black soldier fly and Tenebrio molitor is allowed for aquaculture feed since 2017 (Regulation 2017/893) and for pig and poultry feed since September 2021 (Regulation 2021/1372), but imported lots still need the right health certificate and an establishment that appears on the official list. In the US, ingredient approvals are use-specific: black soldier fly larvae meal was added to AAFCO's ingredient list for salmonid feed in 2018 (The Fish Site). Confirm the product, the use and the destination together.
Which type of manufacturer suits which buyer
EU feed producers that want local supply and the simplest paperwork usually start with a European producer, accepting higher prices and contract-size volumes.
Pet food brands, aquafeed R&D teams and distributors that want finely milled, defatted mealworm or black soldier fly powder in trial lots or container loads, with private-label packs, fit Sino Crown's published order terms. Its black soldier fly oil is available alongside the powders for buyers who source both.
Buyers that need several thousand tonnes a year on long contracts are served mainly by the large industrial producers.
Every buyer should keep a second approved supplier. The 2025 closures and restructurings showed that continuity cannot be assumed.
Seven checks before you choose a supplier
These checks apply to any manufacturer, Sino Crown included, and they turn a brochure comparison into a real one.
1Batch COA for the exact grade. Ask for protein, fat, moisture and ash, and confirm whether the figures are on a dry or as-is basis. The two can differ by several points.
2Written substrate declaration. It should name the feed ingredients used to rear the larvae.
3Certificate copies. Request the GMP+ certificate and check its scope and validity with the issuing body. For US sales, ask for the FDA registration number.
4Sieve test result. Particle size should be stated as a mesh or micron figure with a test result, not just the word fine.
5Defatting method. Ask how the fat is removed, at what temperature, and what residual fat the batch carries.
6Destination paperwork. For the EU, match the species, the animal use and the establishment named on the health certificate with the official list. IPIFF reports that mismatched certificates are a common reason consignments are rejected at the border.
7A trial lot in your own process. Test extrusion, puffing or liquid mixing before signing a contract, and get capacity and lead time in writing.
Frequently asked questions
What is the main difference between Sino Crown and European insect protein manufacturers?Scale and range. European producers run large industrial black soldier fly plants with local EU supply. Sino Crown processes both mealworm and black soldier fly, offers finely milled defatted grades, and ships trial lots and containers from Qingdao.
Does Sino Crown make mealworm protein powder or only black soldier fly?Both. Its range includes defatted mealworm protein powder and dried mealworm powder from yellow mealworm, and defatted black soldier fly protein powder and black soldier fly meal from larvae.
Is FDA registration the same as FDA approval?No. Registration places a facility on FDA's list, and FDA does not issue a certificate of registration. Ingredient acceptance for a given animal is handled separately, for example through AAFCO ingredient definitions.
Can insect protein powder from China be used in EU feed?The two species Sino Crown processes are both on the EU's permitted list, but each consignment must meet the substrate rules, come from a listed establishment and carry a matching health certificate. Check the route for your specific product and use before ordering.
What minimum order does Sino Crown list?Its protein powder pages list a 200 kg trial batch, with 20GP and 40HQ container loads for larger orders.
Why does particle size matter in insect protein powder?Finer powder mixes more evenly and stays suspended better in liquid recipes. At 120 to 200 mesh, particles are about 125 to 75 µm, which is the range Sino Crown states for its milled powders.
