Problems solved by technology

However, due to the intense dehydration of the emulsion during the spray drying process, the protein structure will be greatly changed, which will lead to the oil droplet polymerization and demulsification, which is not conducive to the embedding of oil. It has been verified that the diameter of the microcapsules is larger than that of the fresh emulsion; and when the prepared microcapsules are used in the final application, they will form an aqueous solution again. Due to the extremely low concentration of the emulsified protein, it will easily lead to re-emulsification, which is not conducive to the final application. improved the stability of the prepared microcapsules

Abstract

The invention provides a functional oil microencapsulation and a manufacturing method thereof and relates to a microencapsulation, and the functional oil microencapsulation has the advantages of high stability and immobilized proteinaceous pellicle. The oil microencapsulation is prepared from the following raw materials: functional oil, plant oil, an antioxidant, aqueous-phase main-wall materials, aqueous-phase auxiliary-wall materials, bio-enzyme protein and water. The plant oil serving as a carrier is mixed with the functional oil, then the antioxidant is added, and then the materials are heated and dissolved in water bath, thus obtaining an oil-phase core material solution; the aqueous-phase main-wall materials and the aqueous-phase auxiliary-wall materials are added into deionized water, and then the materials are heated and dissolved in water bath, thus obtaining an aqueous-phase wall material solution; the oil-phase core material solution is added in the aqueous-phase wall material solution, the mixture is sheared and emulsified by a shearing machine, and then is homogenized by a homogenizer, thus obtaining a nanometer-level solution with uniform oil drop diameter; and bio-enzyme is added into the nanometer-level solution, the mixture is placed in hot-water bath for heating and stirring reaction, temperature is raised after the reaction so as to enable the bio-enzyme to be inactivated, and drying is carried out, thus obtaining the functional oil microencapsulation.

Description

technical field [0001] The invention relates to a microcapsule, in particular to a microcapsule formula suitable for preparing vitamins, unsaturated fatty acid esters and other biologically active functional oils and a preparation method thereof, and its application fields relate to feed, medicine and health food additive. Background technique [0002] Microcapsule technology refers to the technology of embedding and sealing solid, liquid or gas in a microcapsule to become a solid particle product. The core material is embedded in the wall material and isolated from the external environment to protect it from the influence of external oxygen, humidity, ultraviolet rays and other factors, so that the unstable core material can prolong the shelf life, and the microcapsules The application also changes the properties of the core material, such as shielding taste, color, special odor and changing fluidity, etc., which is conducive to convenient use and broadens the scope of use...
