Abstract

The invention provides a microcapsule containing sialic acid and carotenoid and a preparation method and application of the microcapsule. The microcapsule is prepared from the following raw materialsin percentage by mass: 1% to 10% of a core material, 20% to 60% of a filling agent, 10% to 50% of vegetable oil, 0.1% to 2% of an oil-phase antioxidant, 0.1% to 2% of a water-phase antioxidant, and 10% to 50% of emulsifier; the core material comprises the carotenoid; the filling agent comprises the sialic acid, and the mass percentage of the sialic acid in the microcapsule is 5% to 30%. Accordingto the microcapsule containing the sialic acid and the carotenoid and the preparation method and application of the microcapsule, the problem that mixing uniformity of the sialic acid and the carotenoid is poor is overcome, the problem that the sialic acid is unstable during high-temperature preparation and consequently the loss is great is also overcome, it is ensured that the content of the sialic acid during the preparation is stable and the content of the carotenoid during storage is stable, and the obtained microcapsule product shows excellence in shelf-life stability.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a microcapsule and its preparation method and application, in particular to a microcapsule containing sialic acid and carotenoids and its preparation method and application. Background technique [0002] Carotenoids are a general term for a class of important natural pigments, which are commonly found in yellow, orange-red or red pigments of animals, higher plants, fungi, and algae. Carotenoids are the main source of vitamin A in the body, and also have anti-oxidation, immune regulation, anti-cancer, and anti-aging effects. Many carotenoids, such as β-carotene, contain double bonds in their molecules. β-carotene crystals are sensitive to air, heat, and light, and are extremely sensitive in solution. They are easily oxidized in the air and become colorless and inactive oxidation products. Therefore, they cannot are applied directly. [0003] Sialic acid, also...
