Abstract

The invention belongs to the technical field of functional food preparation, and discloses a nanofiber membrane capable of simultaneously embedding fish oil and ferulic acid and preparation and application. The preparation method comprises the steps that ferulic acid is dissolved in ethyl alcohol, stirring and mixing are conducted to be uniform, water and zein fish oil are added in sequence, stirring and mixing are conducted to be uniform respectively, and an electrostatic spinning solution is obtained; the electrostatic spinning solution is subjected to electrostatic spinning and dried, and the nanofiber membrane capable of simultaneously embedding the fish oil and ferulic acid is obtained. According to the nanofiber membrane, on one hand, fishy odor of the fish oil can be effectively covered, and oxidation resistance of ferulic acid is fully exerted to improve the oxidation stability of the fish oil; on the other hand, the fish oil is changed into solid fibers from a liquid state, a new idea is provided for development of a functional product of the fish oil, and a wide application prospect in the field of functional food is achieved.

Description

technical field [0001] The invention belongs to the technical field of functional food preparation, and in particular relates to a nanofiber film simultaneously embedding fish oil and ferulic acid, as well as its preparation and application. Background technique [0002] With the improvement of living standards, people pay more and more attention to the nutrition and health improvement functions of food. Fish oil is rich in polyunsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and the intake of EPA and DHA can improve memory and learning, support brain development, etc., so it has good health effect. However, fish oil has a heavy fishy smell, and its taste is difficult to be accepted by most people. Moreover, fish oil is easily oxidized and deteriorates. Therefore, how to cover up the fishy smell of fish oil and improve its antioxidant properties is very important for the development of fish oil functional food. There are still some defic...
