Problems solved by technology

However, the current R&D and production of β-carotene preparations mainly adopt physical and chemical means such as grinding method, high temperature and high pressure treatment method, and solvent method, and the resulting finished products are mostly sold in solid powder state to various related production and application fields. These methods There are certain disadvantages in the bioavailability of the active ingredients of β-carotene, the antioxidant properties and flavor of the finished product. In today's market, consumers have higher demands on the effective absorption rate, smell, and taste of the product. In order to meet market demand and fill product vacancies, this patent is specially invented

Abstract

The invention relates to a beta-carotene emulsion and a preparation method thereof. The emulsion is prepared from the following components in percentage by mass: 30-45% of wall material, 10-15% of core material, 1-2% of an antioxidant and 38-59% of pure water, wherein the core material is prepared from beta-carotene and vegetable oil; the emulsion contains 1-5% of beta-carotene by mass. The preparation method comprises the following steps: dissolving the wall material and the antioxidant in water; then heating to dissolve the core material and the antioxidant; mixing the core material and theantioxidant; performing cutting, homogenization and sterilization to obtain the emulsion. The beta-carotene emulsion provided by the invention is mainly applied to the coloring agents of pastries, sauce products, beverages and the like. The wall material adopted in the invention avoids the acid instability of proteins and the unpleasant odor of modified starch, thus the finished products of the wall material are more widely applied. The prepared beta-carotene emulsion covers the unpleasant odor of the beta-carotene, improves the stability of the beta-carotene and widens the application field and market acceptance of the products.

Description

technical field [0001] The invention belongs to the technical field of food technology, and in particular relates to a beta-carotene emulsion and a preparation method thereof, which is mainly used as a coloring agent for cakes, sauce products, beverages and the like. Background technique [0002] Carotenoids are a general term for a class of natural products. So far, humans have discovered more than 600 carotenoids in nature. Among them, β-carotene, as the precursor of vitamin A, is a type A nutritional food fortifier identified by the Food and Agriculture Organization of the United Nations and the World Health Organization Joint Expert Committee on Food Additives. 52 countries and regions in the world have approved the use of this product. [0003] β-carotene is a tetrahydrocarbon compound, the molecule contains two β-keto rings and 4 isoprene side chains, the whole molecule is symmetrical, that is, two β-keto rings at both ends , breaking at its center can produce two VA...
