Understanding Hard Shell Gelatin Capsules: An Essential Component in Pharmaceutical Delivery
READ MORE >
For global buyers, choosing the right gelatin depends on four factors: raw material source, application requirements, certification needs and quality specifications. Different markets also have different requirements. A pharmaceutical company producing hard capsules may need pharmaceutical-grade bovine gelatin. A food manufacturer serving Muslim consumers may require halal gelatin. A brand targeting Jewish consumers may need kosher gelatin with verified certification.
Understanding the differences between pigskin gelatin, bovine gelatin, bone gelatin, halal gelatin, and kosher gelatin helps buyers reduce compliance risks and select the right supplier.
This guide explains how B2B buyers can evaluate gelatin sources, application requirements, quality parameters, and manufacturer capabilities before making purchasing decisions.
Gelatin is a natural protein ingredient produced from collagen. Collagen is a structural protein found in animal connective tissues, including skin, bones and cartilage.
Through controlled processing, collagen is converted into gelatin with unique functional properties. These properties include gel formation, viscosity control, film formation, and binding ability.
The gelatin production process usually includes several key steps:
The final gelatin quality depends on many factors, including raw material selection, extraction conditions, purification technology, and quality control systems.
For industrial buyers, gelatin is not only a protein ingredient. It is a functional material that must match specific production requirements.
For example:
Capsule manufacturers focus on gel strength and viscosity.
Food companies focus on texture and stability.
Supplement brands focus on source transparency and certification.
Pharmaceutical companies require strict quality control and traceability.
Gelatin mainly comes from three animal sources: Pigskin, bovine hide and bones.
Each source has different market applications and certification considerations.
| Gelatin Type | Source | Common Applications | Main Considerations |
| Pigskin Gleaitn | Porcine skin | Food products, capsules | Limited in Halal and Kosher markets |
| Bovine Gelatin | Cow hide | Capsules, supplements, food | Widely accepted with proper certification |
| Bone Gelatin | Bones(cow， pig or chicken) | Pharmaceuticals, food | Requires strict raw material traceability |
The most important factors in selecting the right gelatin additives are the target market standards and demands, the product application, and religious beliefs.
As a professional and automated gelatin manufacturer, Hengxin can provide customers with clear documentation regarding raw material sourcing and production control.
Pigskin gelatin has been one of the most commonly used gelatin types for decades.
It is produced from cleaned porcine skin through collagen extraction and purification processes.
Because pigskin is rich in collagen, it can provide stable gel strength and good processing performance.
Pigskin gelatin continues to be used in many food and pharmaceutical applications because of its mature production technology and stable supply chain.
In recent years, pork skin gelatin has been widely used in gummy candies, desserts, dairy products, soft capsules and hard capsules.
Based on five-year forecast data from Research and Markets:
“The porcine gelatin market size has grown strongly in recent years. It will grow from $1.08 billion in 2025 to $1.15 billion in 2026 at a compound annual growth rate (CAGR) of 6.6%. ”
- Research and Markets [Porcine Gelatin Market Report 2026]
The pork gelatin market is poised for substantial upward momentum. The firm attributes this growth to the widespread use of gelatin as a food gelling agent, steady supply of pork-derived raw materials, booming confectionery and bakery sectors, rising output of pharmaceutical capsules, and the maturation of collagen extraction technologies.
In regions such as the Middle East and Southeast Asia, Islamic and Jewish dietary laws strictly prohibit pork and all pork-derived derivatives. If commercial buyers and purchasers source gelatin without halal certification, they will be completely locked out of Muslim consumer markets.
For this reason, you should verify whether wholesale gelatin manufacturers hold the relevant qualifications and certifications before selecting your raw materials.
High quality halal bovine gelatin is sourced from all parts of cattle (including hides, bones, tendons, etc.). It is gelatin whose slaughtering, production and storage processes fully comply with Islamic Sharia law.
Slaughter Requirements: At the moment of slaughter, the animal must be alive and healthy, free from any fatal illnesses. If stunning is applied, the stunning method shall be reversible and non-lethal; it must not cause the animal to die prior to the actual throat cut. Under Islamic law, pork and all pork-derived products are strictly prohibited.
Slaughter Procedures: The person performing the slaughter must be a mentally competent Muslim.
The slaughterer shall recite Bismillah or Allahu Akbar at the time of slaughter. An extremely sharp knife must be used; dull or serrated knives are forbidden. The trachea, esophagus, as well as both carotid arteries and jugular veins shall be severed swiftly in a single cut. Following slaughter, all blood must be fully and completely drained from the animal’s body.
Monitoring target market trends is an essential skill for most suppliers, helping them mitigate risks across key operational areas like inventory management and procurement planning.
