What is a Gelatine Capsule?
Gelatine capsules have become an integral part of the pharmaceutical, nutraceutical, and food industries. As a supplier of gelatine capsules, I am often asked about what exactly these capsules are, their properties, applications, and advantages. In this blog post, I will delve into the world of gelatine capsules to provide a comprehensive understanding.
What is Gelatine?
Before we understand gelatine capsules, it's essential to know what gelatine is. Gelatine is a protein obtained by partial hydrolysis of collagen, which is found in the skin, bones, and connective tissues of animals. It is a natural and biodegradable substance. There are two main types of gelatine: Type A, which is derived from acid - treated collagen, usually from pigskin, and Type B, which is obtained from alkali - treated collagen, commonly from bovine hides.
The Composition of Gelatine Capsules
Gelatine capsules are primarily made from gelatine, water, and a plasticizer such as glycerin or sorbitol. The plasticizer is added to make the capsules flexible and prevent them from becoming brittle. In some cases, other additives like colorants, opacifiers, and preservatives may also be included depending on the specific requirements.
The gelatine used in capsules is carefully selected and processed to ensure high quality and purity. It must meet strict regulatory standards to be used in the pharmaceutical and food industries. The production process involves dissolving the gelatine in water, adding the plasticizer and other additives, and then forming the capsules through a dipping process.
Types of Gelatine Capsules
There are two main types of gelatine capsules: hard and soft.
Hard Empty Gelatine Capsules
Hard empty gelatine capsules are widely used in the pharmaceutical and nutraceutical industries. They consist of two parts: a body and a cap. These capsules are available in various sizes, ranging from size 000 (the largest) to size 5 (the smallest). The size is chosen based on the amount of the drug or supplement that needs to be encapsulated.
Hard empty gelatine capsules are popular because they are easy to fill, provide a good barrier against moisture and oxygen, and can be printed with important information such as the product name, dosage, and expiration date. They are also cost - effective and can be used for a wide range of formulations, including powders, granules, and pellets.

Soft Gelatine Capsules
Soft gelatine capsules, on the other hand, are a single - piece, hermetically sealed capsule. They are typically used for liquid or semi - solid formulations. Soft gels are more flexible and can be used to encapsulate substances such as oils, suspensions, and emulsions. The production process for soft gelatine capsules is more complex than that of hard capsules, as it involves a continuous process of forming, filling, and sealing the capsules.
Applications of Gelatine Capsules
Pharmaceutical Industry
In the pharmaceutical industry, gelatine capsules are used to deliver a wide range of drugs. They can mask the taste and odor of the active ingredients, making it easier for patients to take the medication. Gelatine capsules also provide a controlled release of the drug, which can improve its efficacy and reduce side effects. For example, some drugs are formulated in extended - release gelatine capsules to ensure a steady release of the medication over a period of time.
Nutraceutical Industry
The nutraceutical industry also relies heavily on gelatine capsules. Nutraceuticals are products that combine the benefits of nutrition and pharmaceuticals, such as vitamins, minerals, herbal extracts, and dietary supplements. Gelatine capsules are an ideal delivery system for these products because they can protect the active ingredients from degradation and provide an easy - to - swallow form for consumers.
Food Industry
In the food industry, gelatine capsules can be used to encapsulate flavorings, spices, and other food ingredients. They can be used to create innovative food products or to improve the stability and shelf - life of existing products. For example, some food manufacturers use gelatine capsules to encapsulate essential oils, which can be released during cooking or consumption to enhance the flavor of the food.
Advantages of Gelatine Capsules
Biocompatibility
Gelatine is a natural and biocompatible material, which means it is well - tolerated by the human body. It is easily digested and absorbed, making it a safe option for drug and supplement delivery.
Versatility
As mentioned earlier, gelatine capsules can be used to encapsulate a wide range of substances, including powders, liquids, and semi - solids. This versatility makes them suitable for various industries and applications.
Protection
Gelatine capsules provide a good barrier against moisture, oxygen, and light, which can help protect the active ingredients from degradation. This can extend the shelf - life of the product and maintain its quality over time.
Ease of Use
Gelatine capsules are easy to fill, handle, and swallow. They can be easily printed with important information, which is beneficial for both manufacturers and consumers.
