Soft gel manufacturing isn’t an incredibly long, drawn-out process, but it’s certainly interesting. The manufacturing process of high-quality soft gel capsules uses sophisticated technology and the aid of highly-trained machine operators. Years ago, gelatin capsules used to be made from porcine and bovine skin and bones. Today, they can be made from a variety of materials, including chicken, fish and even vegetarian materials.

Gelatin is comprised of a protein which can easily be digested by the body’s enzymes within the intestinal tract. So, when consumers take gelatin capsule supplements, the active ingredients are released and absorbed into the bloodstream. As a leading supplier of private label soft gels StockNutra enjoys explaining how we create our stock items to intrigued customers.

How Does Soft Gel Manufacturing Start?

A soft gel capsule’s gelatin powder is first mixed with glycerin and water. Then, it’s heated and stirred while in a vacuum environment. During the stirring process, any needed flavors or colors are injected into the gelatin mix. The mix, itself, is kept inside a stainless-steel container and kept at a constant temperature.

The process of heating and blending granulate gelatin, along other ingredients, can take a while to complete. For this reason, soft gel manufacturing is normally a drawn-out process. When the appropriate heat is applied, however, a thick syrup is produced. This syrup, called “gel mass,” can be used for additional capsules.

Filling Capsules During Soft Gel Manufacturing

Once the gelatin is prepared, it’s time to encapsulate it. During this phase, a manufacturer uses an encapsulation machine. An encapsulation machine converts gel mass into a thin, gelatin layer. This layer is wrapped around the liquid supplement—forming a soft gel capsule. Check out this YouTube video for an up-close look at high-precision soft gel encapsulation.

 

Drying and Sorting

Once the materials have been encapsulated, the manufacturer needs to dry the capsules. During the drying process, excess gelatin shell moisture is removed. When moisture is removed, the shell shrinks, filling the soft gel capsule completely. Normally, drying can be done by tumbling the capsules—or even drying them in a tray!

The drying process might take a little while, but the sorting process occurs rather quickly. Soft gel encapsulation machines automatically sort and distribute the capsules as soon as they’re created, giving the manufacturer extra freedom to focus on important administrative tasks.

 

How Versatile are Soft Gel Capsules?

They’re very versatile. In fact, a lot of modern supplement brands favor soft gel capsules because of their target demographic favor them. Soft gel capsules are one-piece gelatin capsules made almost exclusively from oil-based or fully liquid formulas. For this reason, they’re incredibly cheap to produce. Because soft gel capsules can be made in a variety of shapes, different product lines can prioritize soft gel capsules which are meant for easy-swallowing situations.

As said earlier, vegetarian and vegan encapsulation is possible. These soft gel capsules use carrageenan, which makes sure the consumer can abide by dietary restrictions while having great freedom in their mineral, supplement and vitamin choices. Plus, soft gel capsules can be specifically designed to be broken down, digested and absorbed in specific areas within the gastrointestinal tract. 

Because some target consumers in the supplement industry have issues with tablet coatings often turn to soft gel capsules, soft gels themselves are becoming incredibly popular in the industry. When providing soft gel capsules to customers, it’s a good idea to consider the slew of custom options available. StockNutra manufactures the highest quality soft gels for distribution.
