The Science Behind Spirulina Hard Capsules Processing

Spirulina is a nutrient-rich blue-green algae that is widely used in health foods and nutritional supplements. Spirulina hard capsules are a common form of spirulina product. Spirulina hard capsules processing involves a series of complex steps. This article will delve into the science of spirulina hard capsules processing.

Harvesting and drying of spirulina

Spirulina is usually harvested by centrifugation or flotation. After harvesting, spirulina needs to be dried for further processing. Drying methods include spray drying and freeze drying, both of which can effectively retain the nutritional content of spirulina.

Crushing and screening

The dried spirulina needs to be crushed into a fine powder for easy filling into capsules. The crushing process requires controlling the particle size distribution of the powder to ensure capsule consistency and quality. The crushed spirulina powder also needs to be screened to remove any large chunks or impurities.

Capsule manufacturing and filling

Capsules are usually made of gelatin or plant-derived materials. The capsule manufacturing process requires precise control of the thickness and hardness of the capsule shell to ensure its stability during storage and transportation. The filling process involves filling the spirulina powder into the capsule shell and then sealing the capsule shell. This process requires precise control of fill levels to ensure a consistent amount of spirulina in each capsule.

Quality control and packaging

Each production batch of Spirulina hard capsules requires strict quality control, including testing the nutritional content, microbial contamination and heavy metal content of Spirulina. Qualified spirulina hard capsules will be packaged in moisture-proof and light-proof packaging materials to ensure the stability and shelf life of the product.

Conclusion

Spirulina hard capsules processing is a science that involves many fields such as biology, chemistry, and engineering. Through scientific methods and strict quality control, we can produce high-quality spirulina hard capsules and contribute to people's health.
