Embodiment 1

[0029] Take 2% lecithin, dissolve the two wall materials in acetate buffer with a ratio of 1:3 of chitosan:lecithin, stir with a magnetic stirrer at a speed of 700r / min for 20min, Lecithin and chitosan stock solutions were obtained, respectively. Mix 5% ginger essential oil, 2.5% ethanol and 2% Tween 80, add it to the lecithin stock solution, and stir it with a constant temperature magnetic stirrer at a speed of 800 r / min for 25 minutes to obtain a primary emulsion; The sugar stock solution was added to the primary emulsion, and stirred at a constant temperature of 40 °C and a speed of 800 r / min for 30 min to obtain a secondary emulsion; after adjusting the pH of the secondary emulsion to 3, homogenize at 17000 r / min for 20 min Wet microcapsules are obtained; after the wet microcapsules are pre-frozen at -80° C. for 24 hours, and then vacuum freeze-dried for 48 hours, the self-assembled ginger essential oil microcapsules are obtained.

Embodiment 2

[0031] Take 1% pectin, dissolve the two wall materials in acetate buffer at a ratio of pectin: soybean protein isolate of 1:5, stir with a magnetic stirrer at a speed of 800 r / min for 13 min, Pectin and soy protein isolate stock solutions were obtained, respectively. Mix 3% ginger essential oil, 1% glycerol and 1.5% fatty acid monoglyceride, add it to the pectin stock solution, and stir it with a constant temperature magnetic stirrer at a speed of 900r / min for 30min to obtain a primary emulsion; The protein isolate stock solution was added to the primary emulsion, and stirred at a constant temperature of 50 °C and a speed of 700 r / min for 40 min to obtain a secondary emulsion; after adjusting the pH value of the secondary emulsion to 4.5, homogenize at 18000 r / min. Wet microcapsules were obtained in 15 minutes; the wet microcapsules were pre-frozen at -80°C for 24 hours, and then vacuum freeze-dried for 48 hours to obtain self-assembled ginger essential oil microcapsules.

Embodiment 3

[0033] Get 0.4% calcium stearoyl lactylate, dissolve two kinds of wall materials in the phosphate buffer solution with calcium stearoyl lactylate: gelatin at a ratio of 1:9 respectively, and use a magnetic stirrer under the speed condition of 950r / min. Stir for 25 min to obtain calcium stearoyl lactylate and gelatin stock solutions, respectively. Mix 9% ginger essential oil, 4.5% propylene glycol and 3% Tween 20 with span40 compound emulsifier, add it to the calcium stearoyl lactylate stock solution, and stir with a constant temperature magnetic stirrer at a speed of 10000r / min 18min to obtain the primary emulsion; add the gelatin stock solution to the primary emulsion, stir at a constant temperature of 45°C and a speed of 900r / min for 26min to obtain the secondary emulsion; after adjusting the pH of the secondary emulsion to 6, at 20000r / min The wet microcapsules were obtained by homogenizing for 10 minutes under the condition of -1 The self-assembled ginger essential oil mi...

Abstract

The invention discloses a self-assembled fresh ginger essential oil microcapsule and a preparation method thereof, and the microcapsule is prepared by taking fresh ginger essential oil as a core material and two or more materials with opposite charges as wall materials, carrying out electrostatic interaction on raw materials including an emulsifier, self-assembling, and freeze-drying to obtain stable microcapsule powder. The ginger essential oil microcapsule prepared by the invention is simple in process operation and high in finished product stability, and has a medical and edible practical value.

Description

technical field [0001] The invention relates to the technical field of functional foods, and more particularly to a self-assembled ginger essential oil microcapsule and a preparation method thereof. Background technique [0002] Ginger essential oil is a natural extract of edible and medicinal plants, and it contains a variety of active ingredients that make it contain a variety of effects. Ginger essential oil mainly includes other non-volatile components such as hydrogen-containing terpenes, oxygen-containing terpenes and phenols. The specific components are zingiberene, β-sesquiphellandrene, α-curcumene, α-cedrene, α- Terpenes such as junipene and α-farnesene. 6-gingerol, 8-gingerol, 10-gingerol and zingerone in ginger essential oil have strong anti-inflammatory and anti-apoptotic effects, and also have strong antioxidant effects in vivo and in vitro; at the same time, Ginger essential oil also plays a role in lowering blood pressure and blood lipids, protecting the cen...
