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

Embodiment 1 to 4

[0023] In a 500ml container, add sitosterol, rice bran oil, polyglycerol monostearate (HLB 12) and sucrose stearate (HLB 13) shown in Table 1 below, heat to 110°C and melt under stirring The formed transparent solution is used as the oil phase. Add deionized water to a 2L container, heat to 85°C, add the oil phase to the water phase, stir at 6000rpm for 20 minutes, cool to 30°C, and filter through a 100-mesh sieve.

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 invention relates to an aqueous beverage and a preparation method thereof, in particular to an aqueous beverage containing phytosterol and a preparation method thereof. Background technique [0002] Phytosterol is the general term for various sterols in plants. At present, there are more than 40 kinds of them, the main component of which is sitosterol, accounting for about 50%; the second is campesterol, accounting for about 33%; the third is stigmasterol , brassicasterol, etc. Phytosterols are steroidal compounds with a hydroxyl group at the 3-position, which can be divided into three categories according to their chemical structure: 4-non-methyl sterol, 4-monomethyl sterol and 4,4’-dimethyl sterol. Phytosterols are usually flaky or powdery white solids with relatively high melting points, for example, the melting point of stigmasterol is 167-170°C. The relative density of sterol is slightly higher than water, insoluble in water, soluble in ethe...
