Gelatin, as a capsule material with a long and esteemed history, has been the pharmaceutical industry's top choice since the mid-19th century. Despite the emergence of many new capsule materials on the market due to advancements in science and technology, gelatin's position remains unshakable.

Firstly, gelatin is a protein extracted from animal skin, bone, and connective tissue, making it extremely biocompatible. The body can easily digest and absorb gelatin, making it an ideal carrier for oral medicines. Furthermore, gelatin is widely recognized for its safety and has been approved by the US Food and Drug Administration (FDA) as a safe food ingredient. Gelatin also possesses stable physical properties such as good elasticity and plasticity. This allows gelatin capsules to maintain their shape and structure under different temperature and humidity conditions, ensuring the stability and effectiveness of the drug.

Additionally, gelatin boasts excellent processing properties; it can be easily molded into capsules of various shapes and sizes to accommodate different drug dosages and release requirements. The molding process for gelatin capsules is simple and cost-effective—this is one of the key reasons why manufacturers choose it. Moreover, gelatin capsules can be modified for various functions as needed—such as sustained release or targeted release—by adjusting their formulation and processing methods to meet specific drug release characteristics.

Finally, as a biodegradable material, gelatin capsules have a minimal impact on the environment. They do not release harmful chemicals during decomposition, aligning with the current growing demand for environmental protection and sustainable development. Due to the long history and extensive use of gelatin capsules, consumers have a high level of acceptance for them. Many people believe that gelatin capsules are safe and reliable, which also contributes to why manufacturers continue to choose gelatin as a material. In many countries and regions, the production and use of gelatin capsules are subject to strict regulations that ensure their quality and safety. This provides additional confidence to manufacturers and consumers.

In conclusion,

Despite the emergence of various new capsule materials on the market, gelatin remains the material of choice for capsule manufacturers due to its biocompatibility, stability, ease of processing, functionality, environmental friendliness, consumer acceptance and regulatory support. As technology continues to advance and consumer needs evolve, gelatin is constantly innovating and improving in order to maintain its leading position in the field of capsule manufacturing.
