The term micronisation refers to a process of significantly reducing the size of particles by grinding. A synonym for micronisation is therefore also ultra-fine grinding. Micronisation produces a so-called micronised powder that is used in various industries. Examples include fruit powder, herb powder, flour and beverage powder as well as the so-called “superfood” in micronised form. In addition, the micronisation process is used in the pharmaceutical industry for the production of various active pharmaceutical ingredients. In numerous branches of industry, plastics are also micronised for various applications.
Depending on the product that is manufactured using the micronisation technique, the application of this technique has various advantages and benefits. For example, the consistency is improved, this is especially true in products of the cosmetics industry: micronised ingredients are often found in skin creams and lotions. In addition, the texture and sensory properties of the products are more pleasant. This is a particular advantage when products such as superfoods or botanicals are taken orally.
The fine pulverisation makes it easier to take. In some products, the bioavailability increases, which indicates the period, extent and location in which the ingested remedy takes effect.
There are several methods of micronisation to choose from, depending on the remedy being used and what one wants to achieve with micronisation. A widely used method of micronisation is spray drying. In addition, grinding the respective ingredients is a widely used method. There are still various options available for grinding – for example, cold grinding or jet milling can be used.
A very modern method of micronisation is the PGSS process, which uses high pressure to produce small particles. The PGSS process can be used to produce different shapes of the small particles
