| خلاصه مقاله | Introduction: Corn stigma (Maydis stigma) is the waste and remains of corn cultivation, which has been used in traditional medicine for the treatment of diseases since ancient times. This agricultural by-product is rich in bioactive compounds such as flavonoids, carbohydrates, steroids, alkaloids, volatile oils, saponins, tannins, vitamins and proteins that have many biological properties such as antioxidant, anti-fatigue and anti-fat. Blood is added to the corn silk extract. Today, Maydis stigma extract has received much attention as a natural antioxidant that can be used as a health-promoting agent and food additive. Methods and Materials: The main goal of this study was the encapsulation of Maydis stigma extract to increase its stability and its use in food products. For this purpose, Maydis stigma extract was loaded into liposomal structures and vitamin C was encapsulated along with it to strengthen the antioxidant activity of the extract. Results: Nanoliposomes loaded with extract/vitamin C with a particle size of 86.58 and a surface charge of -22.9 mV were coated with a protein called zein, which is derived from corn. The positive surface charge created on the coated liposomes proved the successful coating of nanoliposomes with cationic zine polymer. By increasing the concentration of coated polymer, the size of nanoliposomes increased. The images obtained from the electron microscope showed the formation of spherical particles. FT-IR spectroscopy confirmed the interactions between lipid bilayers and bioactive compounds of the extract as well as vitamin C. Conclusion and discussion: Therefore, the produced and coated complex is an oxidation-resistant compound that can be used to enrich different foods, and due to its nanolipidic nature, it will release in gastrointestinal conditions. |
