Abstract

The invention discloses a [beta]-carotene emulsion and a preparation method thereof. The preparation method comprises the following steps: adding an emulsifier into water to obtain a water-phase mixture; dissolving [beta]-carotene in edible oil to obtain an oil phase mixture; and mixing the water-phase mixture and the oil-phase mixture according to a certain proportion, and performing subsequent treatment to obtain the [beta]-carotene emulsion, wherein the emulsifying agent is selected from at least one of wheat bran araboxylan, a wheat bran araboxylan-pea protein isolate compound and pea protein isolate. The [beta]-carotene emulsion prepared by the invention has the advantages of high embedding rate and good stability, and the adopted emulsifiers are all from plants and are high in safety, so that the processing and utilization level of plant sugar and plant protein is further improved; and the preparation method disclosed by the invention has the advantages of high safety, easiness in production and low cost, and the prepared [beta]-carotene emulsion can be widely applied to the fields of development of nutritional functional foods and food packaging.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a β-carotene emulsion and a preparation method thereof, wherein the emulsifier used is wheat bran arabinoxylan, wheat bran arabinoxylan-pea protein isolate complex, and / or pea protein isolate. Background technique [0002] As a typical fat-soluble bioactive substance, β-carotene is the most widely distributed carotenoid in nature and the most studied by scholars. As a precursor of vitamin A, it is widely used as an antioxidant and natural colorant, and plays a vital role in the prevention of many diseases in the human body (such as cancer, cardiovascular disease, macular degeneration, cataracts). However, due to the polyunsaturated structure of β-carotene, it is usually accelerated by light, heat, enzymes, metal ions, metal-binding proteins, and microorganisms, resulting in its chemical instability, low bioavailability And low water solubility greatly limits its applica...
