Abstract

The invention discloses a natural carotene microcapsule. The natural carotene microcapsule comprises the following components in parts by weight: 8-18 parts of a core material, 22-75 parts of a wall material, 10-20 parts of vegetable oil, 3-7 parts of d-sodium erythorbate, 1.6-2.2 parts of sodium tripolyphosphate, 1.2-1.8 parts of citric acid and 20-26 parts of maltodextrin, wherein the core material is natural carotene; and the wall material is starch sodium octenylsuccinate, xylitol, tannic acid and zein. The natural carotene microcapsule is high in embedding rate and good in stability, andcan solve the technical problem of low embedding rate of the natural carotene microcapsule in the prior art. The technical scheme of the invention also provides a preparation method of the natural carotene microcapsule.

Description

technical field [0001] The invention belongs to the technical field of natural product microcapsules, and in particular relates to a natural carotene microcapsule and a preparation method thereof. Background technique [0002] Microcapsule technology refers to the use of natural or synthetic polymer materials to wrap dispersed solids, liquids, and even gaseous substances to form tiny particles with semi-permeable or sealed capsules. The formed tiny particles are called microcapsules. , and the diameter is generally 1-1000 μm. Microencapsulation technology has promoted the transformation of the food industry from a low-level primary processing industry of agricultural products to a high-level industry. [0003] Natural carotene is mainly extracted and refined from plants through solvent extraction. The main coloring substances are β-carotene and α-carotene. Natural carotene has a detoxifying effect and is an indispensable nutrient for maintaining human health. It has signi...
