Problems solved by technology

[0003] Many heat-sensitive substances in cumin essential oil are easily decomposed by heat and are easily lost through volatilization, which affects the quality of cumin essential oil
And because cumin essential oil is easy to volatilize, and stability is poor; Insoluble in water, the scope of application is limited

Embodiment 1

[0020] Wall material β -Cyclodextrin and gelatin are mixed in a mass ratio of 5:1, added to deionized water at 60°C, and started to stir, so that the substance is evenly dispersed in deionized water to obtain a wall material solution; add 1% of the wall material solution to the Emulsifier monoglyceride, mix evenly, then add cumin essential oil according to the mass ratio of wall material and core material of 7:1, stir at 10000r / min at high speed for 5min, then pass it into a high-pressure homogenizer, and homogenize at 90°C and pressure 40MPa Two times to form an emulsion with uniform particle size; the obtained emulsion enters the centrifugal spray dryer through the feeding pump to form microcapsule particles. The spray drying conditions are: air inlet temperature 150°C, air outlet temperature 80°C, atomization pressure 0.3MPa.

Embodiment 2

[0022] Wall material β -Cyclodextrin and gelatin are mixed at a mass ratio of 9:1, added to deionized water at 80°C, and started to stir, so that the substance is evenly dispersed in deionized water to obtain a wall material solution; add 5% of the wall material solution Emulsifier monoglyceride, mix evenly, then add cumin essential oil according to the mass ratio of wall material and core material of 10:1, stir at 20000r / min at high speed for 5min, then pass it into a high-pressure homogenizer, and homogenize at 90°C and a pressure of 40MPa Two times to form an emulsion with uniform particle size; the obtained emulsion enters the centrifugal spray dryer through the feeding pump to form microcapsule particles. The spray drying conditions are: air inlet temperature 200°C, air outlet temperature 100°C, atomization pressure 0.5MPa.

Embodiment 3

[0024] Wall material β -Cyclodextrin and gelatin are mixed at a mass ratio of 2:1, added to deionized water at 70°C, and started to stir, so that the substance is evenly dispersed in deionized water to obtain a wall material solution; add 3% of the wall material solution Emulsifier monoglyceride, mix evenly, then add cumin essential oil according to the mass ratio of wall material and core material as 2:1, stir at 15000r / min at high speed for 5min, then pass it into a high-pressure homogenizer, and homogenize at 70°C and a pressure of 30MPa Two times to form an emulsion with uniform particle size; the obtained emulsion enters the centrifugal spray dryer through the feeding pump to form microcapsule particles. The spray drying conditions are: air inlet temperature 150°C, air outlet temperature 80°C, atomization pressure 0.2MPa.

Abstract

The invention relates to a fennel essential oil microcapsule and a preparation method thereof and belongs to the field of preparation of microcapsules. Fennel essential oil is adopted as a core material, a uniform mixture of beta-cyclodextrin and gelatin is adopted as a wall material and monoglyceride is adopted as an emulsifier. The preparation method comprises the following steps of sequentially adding the wall material and the emulsifier into a hot water for dissolving, adding the core material into the solution while stirring, stirring at a high speed for several minutes, under a high pressure of 30-40MPa, and homogenizing twice to form an emulsion with uniform particle size and carrying out spray drying to obtain the fennel essential oil microcapsule. The method is simple in process and the product has good thermal stability and soluble dispersion and can be widely applied in industries, such as food and medicines.

Description

technical field [0001] The invention relates to a fennel essential oil microcapsule and a preparation method thereof, belonging to the technical field of microcapsule preparation. Background technique [0002] Fennel, the dry and mature fruit of fennel belonging to the Umbelliferae family, also known as fennel, glutinous rice, fennel, and fennel seed, has the functions of regulating qi and regulating the stomach, dispelling cold and relieving pain. Contains 3~8% of volatile oil, and the main components in the oil are 50~78% of trans-anisole, α - 18~20% fennelone, about 10% methyl piperonol, anisaldehyde, can be used as a carminative to expel gas during abdominal distension and relieve pain; it can reduce the tension of the stomach and then stimulate it to normalize its peristalsis , shorten the emptying time, and increase the tension and peristalsis of the intestine, thus promoting the discharge of gas. [0003] Many heat-sensitive substances in cumin essential oil are eas...
