Abstract

The invention relates to β-carotene microcapsules rich in sardine oil, a preparation method and application thereof. In the present invention, denatured starch, chitosan, trehalose, sucrose, and monoglyceride succinate are sequentially added to water, stirred while adding, mixed evenly, and the solution is kept at a certain temperature to obtain the water phase, β-carotene crystals, Add lipophilic emulsifier Tween and sardine oil into the oil phase kettle, stir and dissolve to obtain the oil phase, slowly add the oil phase into the water phase, and make a microemulsion by shearing, and the microemulsion is prepared by concentrating, freeze-drying, grinding, etc. Microencapsulated beta-carotene enriched with sardine oil. Compared with the prior art, the obtained β-carotene microcapsules of the present invention not only improve the stability of β-carotene to factors such as light, heat and humidity, but also are rich in sardine oil in the microcapsules, which can combine with β-carotene Play a synergistic effect and improve the health care performance of microcapsules.

Description

technical field [0001] The invention relates to the technical field of health food, in particular to a β-carotene microcapsule rich in sardine oil and its preparation method and application. Background technique [0002] β-carotene is one of the carotenoids. It is an orange-red fat-soluble compound and belongs to tetraterpenoids. β-carotene can effectively scavenge free radicals and reduce the incidence of cancer. Anti-aging effect. However, in the process of food processing and storage, β-carotene has poor stability, is easily oxidized, and is prone to isomerization due to the action of heat, acid and light. In addition, the weakly polar molecular structure determines that β-carotene is insoluble in water and slightly soluble in oil, which limits its application range. The β-carotene oral liquid obtained in actual production has a poor taste and poor stability, so its application in the food industry has great limitations. Now the main method to solve these problems is t...
