Microencapsulation of hydrophobic substances for developing functional ingredients

Essential oils, flavors, and carotenoids present significant challenges in formulation and processing owing to their chemical structures. These hydrophobic & volatile substances are susceptible to oxidation and light. They change or can even lose their properties when coming into direct contact with the environment. For protection and easier handling, as well as for better dosing and targeted release properties, the product and process optimization are very important key factors for all kinds of industry.

This is where microencapsulation offers substantial benefits by protecting sensitive or volatile substances from degradation caused by environmental factors such as moisture, light, heat, and chemical reactions. Microencapsulation is a widely used technology in the food industry, serving as both a fortifying tool and a method for developing functional foods.

What is Fluidized Bed Microencapsulation?

The process of microencapsulation begins with emulsifying the oil with materials that protect against oxidation, such as modified starches, hydrocolloids, or proteins. Stabilization of the emulsion has a decisive influence on the product quality, as it prevents the microcapsules from being destroyed during subsequent processes, thereby protecting the contents from oxidation.

Microencapsulation involves embedding hydrophobic substances into a matrix, with the aid of continuous granulation and drying. Encasing these substances within a polymeric or non-polymeric material allows manufacturers to achieve varied end goals, for example, controlled release under specific conditions, enhancing sensory qualities by masking unpleasant tastes, aromas, or flavors and preventing degradation from environmental factors.
