Let’s start from the scientific definition.
The encapsulation is the set of processes designed to incorporate a substance within another that acts as a protective barrier, obtaining particles and capsules in which the molecule of interest are isolated from the external environment.
Initially developed to preserve and disperse dyes and flavors, encapsulation has now become one of the most intriguing and exciting fields of science when it comes to applied research.
Sphera’s expertise focuses mainly in the field of food technology, where the encapsulation of the ingredients plays a crucial role in the development of functional foods and nutraceuticals. The same concepts also apply to animal feed for livestock, aquaculture and pet food, another growing industry in which we operate.
Micro-encapsulation is not limited to this. Many other areas exploit encapsulation techniques to protect, insulate or simply improve the dispersion of active ingredients. This technique is used in the production of house and personal care products, in the cosmetic industry, in electronics chemicals, in the treatment of wastewater , production of fabrics, in graphics and printing, and of course in the field of pharmaceutical products.
When the particle diameter is less than the micron, the encapsulation process takes the name of nano-encapsulation. The latter allows for such small structures to be easily endocitated at the cellular level, improving aspects such as absorption and bioavailability of the active ingredient.
The nano-particles are excellent carriers for the so-called “drug delivery” or the science that deals with the transportation and facilitatation of the release of drugs in specific body sites.
Sphera is able to apply its technology in the following industrial sectors: food, pharmaceutical, cosmetics and agro-chemical.
