Abstract Antioxidants are very important in the food industry as they contribute to increased product shelf life and also play an important role in the prevention and relief of symptoms of diseases such as atherosclerosis and diabetes. Cinnamon (Cinnamomum zeylanicum) has been used for centuries as a spice, but also has beneficial health properties by the presence of substances such as proanthocyanidins (phenolic compounds belonging to the class of flavonoids). These substances have common properties of antioxidants (anti-inflammatory, anticarcinogenic, among others), as well as potential for the prevention of damage caused by diabetes. Similarly, the ±-tocopherol (a vitamin E constituent) is an antioxidant that plays an important role in the protection of fatty acids in membranes and lipoproteins. However, the addition of antioxidants in foods can present some problems such as low stability, interaction with food matrix components and unpleasant taste. To overcome these problems, the spray chilling process may be used, which consists in the incorporation of active ingredients in a molten carrier, followed by spray in a cold chamber. This method has the advantage of not using organic solvents and to be developed in milder temperatures. The aim of this project is the production of microparticles by spray chilling containing cinnamon proanthocyanidins and ±-tocopherol, to increase stability and mask the taste and aroma of these compounds. The microparticles will be characterized for structure by optical and scanning electron microscopy, size distribution, stability and release profile, and analyzed by infrared spectroscopy, differential scanning calorimetry and X-ray diffraction. To the best of our knowledge, there is no study about coencapsulation of proanthocyanidins and ±-tocopherol by spray chilling. Thus, these microparticles can be used to add value to new products with higher antioxidant content, longer shelf life and functional properties. | |
