Embodiment 1

[0035] The present embodiment provides a kind of preparation method of Artemisia grandis essential oil microcapsules, and its technological process is as follows:

[0036] (1) preparation of purslane polysaccharide

[0037]Harvest fresh purslane, wash it, dry it naturally until the moisture content is lower than 10%, and crush it through an 80-mesh sieve. Use 2 times the mass of petroleum ether to reflux and degrease for 6 hours, filter the filter cake with suction, and dry the filter cake. Add distilled water to the filter cake, add 40 mL of distilled water per gram of filter cake, ultrasonically extract for 40 min at 70°C, filter the extract, and concentrate the filtrate by rotary evaporation at 50°C. Add 2 times the volume of absolute ethanol to the concentrated solution, ethanol overnight, filter with suction, wash the filter cake with absolute ethanol, ether and acetone in sequence, and dry to obtain purslane polysaccharide.

Embodiment 2

[0044] The present embodiment provides a kind of preparation method of Artemisia grandis essential oil microcapsules, and its technological process is as follows:

[0045] (1) preparation of purslane polysaccharide

[0046] Harvest fresh purslane, wash it, dry it naturally until the water content is lower than 10%, and crush it through a 50-mesh sieve. Reflux and degrease with 1.5 times the mass of petroleum ether for 8 hours, filter with suction to obtain a filter cake, and dry the filter cake. Add distilled water to the filter cake, add 40 mL of distilled water per gram of filter cake, conduct ultrasonic extraction for 60 min at 70°C, filter the extract, and concentrate the filtrate by rotary evaporation at 50°C. Add 2 times the volume of absolute ethanol to the concentrated solution, ethanol overnight, filter with suction, wash the filter cake with absolute ethanol, ether and acetone in sequence, and dry to obtain purslane polysaccharide.

Abstract

The invention relates to artemisia sieversiana essential oil microcapsules and a preparation method thereof, in particular to microcapsules prepared by taking natural plant extract purslane polysaccharide and soy isolate protein as wall materials and artemisia sieversiana essential oil as a core material. Therefore, the stability of the artemisia sieversiana essential oil in humid environments such as light, oxygen, high temperature and humidity can be improved, the activity of the artemisia sieversiana essential oil can be better preserved, and the release speed and uniformity of the artemisia sieversiana essential oil can be controlled. As the wall material is the natural plant extract, the safety is good, and the wall material also has rich nutritional value and medicinal value. The purslane polysaccharide and the soy isolate protein are used as wall materials together, so that the medicinal value of the purslane polysaccharide can be applied, the embedding rate of the microcapsule can be increased, and stable product quality is obtained.

Description

technical field [0001] The invention relates to a health food, in particular to a microcapsule of Artemisia grandis essential oil which uses purslane extract as a wall material and a preparation method thereof. Background technique [0002] Artemisia sieversiana Ehrhart exWilld. is a plant of the genus Artemisia in the Asteraceae family. It contains volatile oil, vinegar and azulens. It is used in folk medicine for its anti-inflammatory, heat-clearing and hemostatic effects. It is used in highland areas to treat Burns caused by ultraviolet radiation from the sun. "Heilongjiang Flora" also has relevant records that "the whole plant and flower buds have anti-inflammatory and analgesic effects". Therefore, Artemisia grandis essential oil has great medicinal effects. Artemisia grandis clear oil is peacock blue and has the aroma of wormwood and vanilla. The main components of natural plant essential oils are terpenes, sesquiterpenes and their oxides, as well as carbonyl compou...
