Problems solved by technology

However, a large amount of emulsifiers will bring many adverse effects to water-based beverages. As a food additive, emulsifiers are mostly prepared by chemical methods, and harmful substances (such as residual solvents or heavy metals) will inevitably be introduced during the synthesis process. ), the country has strict regulations on the scope and dosage of its use, and the use of exceeding the scope or exceeding the standard will bring hidden dangers to the safety of users
At the same time, too high emulsifier content will also affect the taste of the product, or cause users gastrointestinal discomfort
In addition, the dispersibility of the emulsion prepared by the existing method needs to be further improved

Abstract

The invention provides a water-based beverage containing phytosterol and a preparation method thereof. The water-based beverage contains the phytosterol, vegetable oil and at least one emulsifying agent. In the water-based beverage containing phytosterol and the preparation method thereof, the phytosterol is successfully dispersed into the water-based beverage, the consumption of the emulsifying agent is reduced, the temperature required by a melting raw material in the preparation process is reduced, the formed oil phase droplets containing the phytosterol are less than 1 micron, the water-insoluble phytosterol does not need to be prepared into the phytosterol which has high price and does not belong to a normal food component, the phytosterol is directly added into the water-based beverage by using oil-in-water emulsifying technology to obtain the water-based beverage containing the phytosterol with excellent stability, agglutination of the phytosterol due to crystallization can be effectively inhibited, and sediments are not produced even in long-time storage.

Description

technical field [0001] The present invention relates to an aqueous beverage and a preparation method thereof, in particular to an aqueous beverage containing phytosterols and a preparation method thereof. Background technique [0002] Phytosterol is a general term for various sterols in plants. There are more than 40 kinds of sterols known at present. The main component is sitosterol, accounting for about 50%; campesterol, accounting for about 33%; and stigmasterol , rapeseed sterol, etc. Phytosterols are steroids with a hydroxyl group at the 3-position. According to their chemical structures, they can be divided into three categories: 4-nonmethyl sterol, 4-monomethyl sterol and 4,4'-dimethyl sterol. Phytosterol is usually a flake or powdery white solid with a relatively high melting point, for example, the melting point of stigmasterol is 167-170°C. The relative density of sterol is slightly higher than that of water, it is insoluble in water, but soluble in various organ...
