I. What is Mesh(Definition)
Mesh = the number of holes per inch on a sieve. The higher the number, the finer the particles. It is the industry-standard unit for describing gelatin granulation (particle size).

| Mesh | Approximate Particle Size | Appearance Description |
|---|---|---|
| 8–10 | 2.0–2.36 mm | Coarse granules, similar to sea salt |
| 18–20 | ~0.84 mm | Sugar-like / Medium coarse |
| 30 | ~0.59 mm | Sugar-like |
| 40 | ~0.42 mm | Fine sand-like / Common standard powder |
| 60 | ~0.25 mm | Fine powder |
| 80 | ~0.18 mm | Fine powder |
| 100 | ~0.15 mm | Very fine |
| 200 | ~0.074 mm | Ultra-fine powder, like flour |
II. What Does Mesh Affect?
Affects:
- Hydration/Swelling speed: Fine particles have a larger surface area → swell faster; coarse particles take longer to soak.
- Dissolving speed: Fine particles melt faster in 50–60°C hot water, while coarse particles are slower.
- Clumping risk: If fine powder is dumped straight into water, it easily forms clumps (gooey outside, dry inside). It needs dry blending first or high-shear mixing.
- Flowability/Dust/Bulk density: Fine powder flows poorly and creates dust, affecting the handling experience.
- Mixing uniformity: In dry-mix products, fine powder blends more easily with other powders.
Does NOT Affect:
- Bloom strength: Determined by the molecular structure, has nothing to do with mesh size. The Bloom stays the same whether the batch is ground coarse or fine.
- Inherent viscosity: The viscosity after it is fully dissolved is determined by the gelatin itself; mesh size only affects the dissolving process.
- Transparency/Color: For the same raw material, mesh size doesn't change its chemical specs or optical nature.
III. How to Choose the Right Mesh
Core logic: The finer it is, the faster it dissolves and disperses; the coarser it is, the slower it hydrates and the less likely it is to clump.
1. Choose by Application
| Application | Recommended Mesh | Reason |
|---|---|---|
| Softgels / Hard capsules | 30–60 mesh (or finer) | Even film forming, consistent capsule wall strength. Melting tanks have mixers, balancing speed and clumping prevention; good flowability for filling. |
| Gummies / Jellies (gummy, jelly) | 8–20 mesh (coarse) or 20–40 mesh | Coarse granules hydrate slower, making the boiling process easier to control. Easy to feed without clumping; gives the final product a chewier texture. |
| Marshmallows | 40–60 mesh | Needs fast dissolving to match high-speed whipping processes. |
| Baking / Desserts (puddings, mousses) | 40 mesh | The most versatile spec, a good balance of solubility and handling. |
| Yogurt / Dairy products | 60–80 mesh | Low-temp systems with a short dissolving window need fine powder for quick dispersion. |
| Protein bars / Nutrition bars | 70 mesh | Finer particles absorb faster and mix more evenly with other ingredients. |
| Meat jellies (aspic) | 8–20 mesh | Long heating and boiling times mean coarse granules are plenty good enough and cheaper. |
| Beverage clarification (wine, beer) | 100–200 mesh | Ultra-fine particles disperse quickly for great clarification without adding cloudiness. |
| Instant drinks / Collagen peptide powder | 60–100 mesh (or 80–120) | Aims for instant dissolving, no gritty feel, smooth texture; for true "cold-water instant" dissolving, peptide products are recommended. |
| Tablet binders / Direct compression | 80–100+ mesh | Dry-mixed with other powders, needs matching particle size to ensure uniform blending. |
2. Coordinate with Bloom Strength
Mesh (particle size) and Bloom (gel strength) are two totally independent specs, but they need to be chosen together:
- High Bloom → Hard gel, strong bounce/elasticity.
- Fine Mesh → Fast dissolving, smooth texture, high clarity.
Real-world case: When making clear jellies, you not only need high Bloom for gelling, but also a finer Mesh (like 40–60 mesh) to avoid cloudiness or a grainy texture caused by uneven hydration.
3. Process and Equipment Considerations
| Process Factors | Recommendation |
|---|---|
| High-speed production lines / Auto-filling | Go for fine Mesh (60+). Good flowability, less likely to clog machines. |
| Small batches, manual prep / Slow mixing only | Coarse Mesh (20–40) is more forgiving. Less likely to clump from uneven mixing (fine powder clumps easily). |
| Cold dissolving process (low-temp systems) | Fine Mesh disperses much better at low temps; coarse Mesh might need heating to fully hydrate. |
| Dry mixing with other powders (tablets, instant mixes) | Recommend matching Mesh sizes to prevent separation; or use fine Mesh as a carrier. |
| Dumping straight into water (no dry premixing) | 20–40 mesh is the safest bet to avoid clumping risks. |
4. Storage and Stability
IV. 4 Questions to Lock In Your Final Mesh
If you're not sure which mesh size to pick, answer these 4 questions in order:
- What's your melting temp and time?
→ 60°C (140°F) hot water + over 30 mins → Coarse granules (8–30 mesh) will do fine, lowest cost.
→ Low temp or short time → Go with 40 mesh or higher. - Do you have high-shear / strong mixing?
→ Yes → Fine powder (60–80 mesh) is safe to use.
→ Slow mixing only → Fine powder will clump. We recommend ≤40 mesh, or teach the customer to dry-blend first. - Is the gelatin dumped straight into water, or dry-mixed with other powders first?
→ Dry-mix systems (tablets, instant powders) → Fine powder 80 mesh and up.
→ Straight into water → 20–40 mesh is the most stable. - What spec is your current process using?
→ When switching suppliers, try your best to match the mesh they are already using so they don't have to change their process—this is the most easily overlooked yet deal-breaking practical tip!
V. B2B Purchasing Tips
Quotes & Specs
- Quotes must state two things: Mesh and Bloom (gel strength) must be listed side-by-side (e.g.,
180–200 Bloom / 20–40 mesh). You can't skip either. - Costs & Pricing: Grinding costs money. Fine powder is slightly pricier with lower yield (sieve loss), while coarse granules are the cheapest. If the customer has no special requests, push mainstream specs (food-grade usually takes 20–40 or 30–60).
Customization & Service
- Custom particle size distribution: You can offer "bimodal / custom particle distribution" as a unique selling point—like "90% passes 40 mesh, ≤5% finer than 100 mesh". This level of control is a big deal for major gummy factories (cuts down dust, keeps melting consistent).
- Sample testing: When sending samples, send 2 small samples of different mesh sizes at the same time for them to run on their production line. This works way better than just trying to explain it in text.
VI. Quick Decision Summary
VII.How to choose the right mesh for homemade gelatin-based foods
Fine powder clumps easily; coarse powder hydrates slowly. The most recommended "golden mesh size": 20 mesh.
For household use, 20 mesh is the best compromise that balances hydration speed and anti-clumping.
Compared with coarse granules (8–10 mesh): hydration takes 30–60 minutes, which is too time‑consuming and dampens our enthusiasm for homemade projects.
Compared with fine powder (40–60 mesh): although it hydrates in just 5–10 minutes, its error tolerance is extremely low—a slight carelessness causes clumping, forming lumps that are wet outside but dry inside (commonly called "fish eyes"), which will not dissolve no matter how you heat them afterwards.
The advantage of 20 mesh: the particles are the size of fine granulated sugar. Soaked in cold water for about 15–20 minutes, they absorb enough water and become soft—fast enough for most needs. At the same time, the gaps between particles allow water to penetrate easily, making clumping highly unlikely, and it is well suited for home kitchens without industrial high‑shear mixing equipment.
Gelatin sheets are a foolproof choice for home use. They do not involve "mesh size" specifications and can be used immediately after soaking in ice water.
Summary
Mesh is the "physical form" indicator of gelatin, determining how fast it blends into a system and how evenly it disperses. When choosing, don't look at Mesh in isolation. You also need to consider Bloom strength, raw material source (pork/beef/fish), dissolving temp, final mouthfeel, and production equipment compatibility. If you are planning to purchase from EKING, a leading gelatin supplier in China, you can request custom free samples of different Mesh sizes from our factory for bench testing before locking in your final specs.
