Resumen
BACKGROUND:Omega-3 fatty acids are known for their various health benefits. Chia is the richest vegetable source of omega-3 fatty acids. However, its oil is highly susceptible to oxidative deterioration and should be protected for incorporation into food matrices. This work aimed to study the incorporation of different chia oil microcapsules in a powdered beverage, analyzing the effect on the physicochemical characteristics and the stability during storage.RESULTSDifferent types of microcapsules were obtained: monolayer microcapsules using sodium caseinate and lactose as wall material and multilayer microcapsules produced through electrostatic deposition using lecithins, chitosan, and chia mucilage as the first, second, and third layer, respectively. The results demonstrated an efficient enrichment of smoothies, with omega-3 fatty acid values ranging from 24.09% to 42.73%, while the food matrix powder did not contain this component. This finding confirms the successful enrichment of the smoothie in omega-3 fatty acids. These powder beverages exhibited low moisture content (≤ 2.91%) and low water activity (≤ 0.39). The aerated, packed density and compressibility assays indicated that adding microcapsules made the powders less dense and compressible. The color of the original powdered beverage was not modified. The dispersibility reflected an acceptable instantaneity, reaching the maximum obscuration after 30 s of stirring. The solubility of all the enriched products was higher than 70%, whereas the pH was 6.8. The contact angle indicated an excellent ability to be reconstituted in water. The analysis of the glass transition temperature showed that the storage temperature (25°C) was adequate. The peroxide value of all the products was low throughout the storage (≤ 1.63 meq peroxide/kg of oil at 90 days at 25±2 °C), thus maintaining the quality of the microencapsulated chia oil. CONCLUSIONSThe results suggest that incorporating the mono and multilayer chia oil microcapsules studied could be a viable strategy for enriching smoothies with the omega-3 fatty acids present in chia seed oil.
