Understanding Gelatin Mesh Size: What It Means and Why It Matters

When it comes to gelatin production and formulation, mesh size is one of those subtle yet critical factors that can influence everything from processing efficiency to end-product quality. Whether you're creating softgel capsules, gummy supplements, or functional foods, the particle size of gelatin—defined by its mesh size—plays a key role in consistency, solubility, and overall performance.

In this guide, we’ll explore what mesh size means, how it’s measured, why it matters across industries, and how to choose the right one for your specific application.

What Is Mesh Size in Gelatin?

Definition of Mesh Size

Mesh size refers to the number of openings per linear inch in a standard screen or sieve used to classify powdered materials. The higher the mesh number, the smaller and finer the particles:

• 8 mesh = relatively coarse particles
   
• 20 mesh = medium-grade powder
   
• 60 mesh = very fine powder
   

So, when a gelatin is labeled 60 mesh, it means it passes through a sieve with 60 holes per inch—resulting in a fast-dissolving, highly consistent powder.

Why Mesh Size Matters in Gelatin Production

Different gelatin applications require different performance characteristics:

• Finer mesh sizes dissolve more rapidly—ideal for pharmaceutical gelatin applications like softgel capsules and thin film coatings.
   
• Coarser mesh sizes are more suitable for food production, such as bakery or confectionery products, where slower hydration may be acceptable or even preferred.
   

At FNP Gelatin, we offer customizable mesh sizes tailored for food, pharma, and nutraceutical industries—ensuring each batch meets the exact standards for quality, solubility, and processing behavior.

Case Study: How Mesh Size Optimization Improved Gelatin Performance in a Gummy Supplement Line

Background: A leading manufacturer of gummy supplements was experiencing inconsistencies in texture and solubility across different batches of their products. While the gummies were marketed as having a smooth, easy-to-consume texture, customer feedback indicated that some batches were either too firm or too gooey. The company realized that the variation might be due to the mesh size of the gelatin used in production.

Solution: The manufacturer partnered with FNP Gelatin to investigate the impact of mesh size on their formulation. After thorough testing, they discovered that switching to a finer mesh size (60 mesh) for their gelatin resulted in a smoother, faster-dissolving consistency, which improved the texture of the gummies significantly. The finer mesh also allowed for more consistent hydration, which helped maintain the quality of the product batch after batch.

Additionally, the finer mesh gelatin improved the production efficiency by reducing the time required for the hydration process, which meant they could increase output without compromising on quality.

Results:

• Improved Product Consistency: The gummies became more consistent in texture, meeting the desired standards for both softness and chewiness.
   
• Faster Dissolution Rate: Customers reported that the gummies dissolved more evenly, contributing to a better consumer experience.
   
• Increased Production Efficiency: With the faster hydration process, production times were reduced by 15%, allowing the company to scale up without sacrificing quality.
   
• Enhanced Customer Satisfaction: The improved texture and consistent quality led to a reduction in customer complaints, resulting in better customer retention and a 10% increase in repeat orders.
   

Conclusion: This case demonstrates how mesh size optimization can make a significant difference in both the quality and production efficiency of gelatin-based products. For manufacturers, understanding the critical role of mesh size is key to achieving the desired product characteristics and maintaining operational efficiency.

Mesh Size vs. Bloom Strength: What’s the Difference?

While often discussed together, mesh size and Bloom strength refer to completely different properties:

• Mesh size = particle size
   
• Bloom strength = gel strength
   

Choosing the right mesh size alongside an appropriate Bloom strength ensures optimal gelling, texture, and hydration—especially in applications like jellies, marshmallows, and capsules.

Mesh Size in Pharmaceutical vs. Food Grade Gelatin

Pharmaceutical Gelatin

In pharma applications, finer mesh sizes are preferred to ensure uniform film formation and smooth encapsulation. Mesh consistency affects not only capsule wall strength but also dissolution time—crucial for drug delivery.

Food Grade Gelatin

For food-grade gelatin, the ideal mesh size varies based on the product. A 20 mesh gelatin is commonly used for:

• Gummies and jellies
   
• Marshmallows
   
• Bakery glazes
   
• Beverage stabilization
   

What Makes Gelatin Food Grade or Pharmaceutical Grade?

Pharmaceutical gelatin must meet stricter standards in terms of:

• Microbiological safety
   
• Heavy metal residue limits
   
• Particle size uniformity (usually tighter mesh specifications)
   

These are typically governed by Good Manufacturing Practice (GMP) protocols.

Food-grade gelatin, while slightly less stringent in regulation, still demands consistent solubility, color, and flavor neutrality—especially in clear confections or beverages.

Factors That Affect Gelatin Mesh Size During Processing

Several variables influence the final granule size during gelatin manufacturing:

• Drying temperature and duration
   
• Milling and sieving techniques
   
• Source of raw material (e.g., bovine hide vs. porcine skin)
   

As a trusted edible gelatin manufacturer, FNP Gelatin maintains strict control over these variables to ensure consistent mesh output that aligns with customer needs.

Related Properties to Consider When Buying Gelatin

When selecting gelatin for your formulation, mesh size should not be considered in isolation. Two key related factors include:

• Bloom Strength: Impacts gel firmness and structure.
   
• Viscosity: Affects mixing behavior and mouthfeel in food applications.

Frequently Asked Questions (FAQ)

Is mesh size the same as particle size?

Not exactly. Mesh size refers to the sieve specification, while particle size is the actual diameter, usually measured in microns.

How do I convert mesh size to microns?

While not exact, here are some common estimates:

• 200 mesh ≈ 74 microns
   
• 100 mesh ≈ 150 microns
   

What’s the best mesh size for collagen peptide supplements?

A finer mesh (e.g., 60–100) ensures rapid solubility—ideal for instant drink mixes or capsules.

Does gelatin mesh size affect capsule fill uniformity?

Yes. Finer mesh gelatin allows for better flowability and more consistent capsule filling, especially in automated production lines. Coarse powders may lead to clogging or weight variation across batches.

Can I blend different mesh sizes to balance performance and processing?

Absolutely. Some formulators blend coarse and fine mesh gelatin to balance hydration speed with stability. However, you must test for consistency and compatibility in your system.

How should gelatin mesh size be stored to prevent quality loss?

Store in a cool, dry environment in airtight containers. Finer mesh gelatin is more prone to moisture absorption and caking, so avoid high humidity conditions.

Is there a regulatory requirement for mesh size in pharmaceutical gelatin?

While mesh size isn’t always a regulatory mandate, GMP-compliant pharmaceutical gelatin usually follows strict internal specifications for particle uniformity, especially for softgel and capsule-grade products.

Will mesh size affect the final gel clarity or texture?

Yes. Coarse mesh gelatin may hydrate unevenly and leave particles or turbidity in clear gels. Finer mesh offers smoother texture and better visual clarity, especially in transparent confections and beverages.

Final Thoughts: Mesh Size Is More Than Just a Number

Choosing the right gelatin mesh size is not just a technical specification—it can influence your product’s texture, dissolution rate, production time, and even regulatory compliance. Whether you're developing a pharmaceutical capsule, collagen peptide supplement, or a functional food, mesh size matters.
