Embodiment 1

[0046] The preparation method of embodiment 1 bellflower seed essential oil

[0047] In order to reduce impurities, the platycodon grandiflorum seeds are cleaned and dried in the sun until the water content is less than 12% before crushing.

[0048] 1, the preparation method of bellflower seed essential oil, comprises the following steps:

[0049] (1) Supercritical CO 2 Extraction: wash 1500g of bellflower seeds and dry them in the sun until the water content is 12% bellflower seeds, pulverize and pass through a 40 mesh sieve to get pulverized bellflower seed powder, put the crushed bellflower seed powder into a supercritical 5L barrel, and put the supercritical The 5L barrel is placed in the extraction kettle to allow the bellflower seed powder and supercritical CO 2 Supercritical CO 2 Extraction, controlled supercritical CO 2 The extraction pressure is 20.5MPa, CO 2 The flow rate is 44.6L / h, the extraction temperature is 45°C, the separation I pressure is 7MPa, the sepa...

Embodiment 2

[0058] Except the parameters shown in Table 2 are different between Embodiment 2 and Embodiment 3, the rest of the operation steps are the same as Embodiment 1 and will not be repeated here.

[0059] Control parameters and effects in the preparation method of table 2 embodiment 1-3 bellflower seed essential oil

[0060]

[0061]

Embodiment 1-3

[0062] Embodiment 1-3 shows: the platycodon grandiflorum seed oil yield rate that each processing step of the present invention cooperates reasonably with process condition preparation is high, and oil yield rate reaches 25% (the weight (g) / 1500g * 100% of platycodon grandiflorum seed essential oil), Its products are green and safe. Platycodon grandiflorum seed essential oil has a purity of 99%, no solvent residue, moisture and volatile content, peroxide value, and acid value all meet national standards. The production process is simple and the material loss is low, which can realize continuous industrial production.

Abstract

The invention discloses a preparation method and a health production of platycodon grandiflorum seed essential oil. The method comprises the steps of CO2 supercritical fluid extraction, thin-film distilling for dehydrating and deodorizing, molecular distillation for depickling, freezing, decolorizing through a superfilter, and dewaxing through a centrifugal machine, wherein the extraction is performed under a pressure of 20 to 36MPa and at a temperature of 45 to 55 DEG C; the separation I is performed under a pressure of 7 to 9MPa and at a temperature of 30 to 50 DEG C; the separation II is performed under a pressure of 4 to 6MPa and at a temperature of 30 to 50 DEG C; the obtained crude oil of platycodon grandiflorum is subjected to thin-film distilling for dehydrating and deodorizing, molecular distillation for depickling, freezing, decolorizing through a superfilter, and dewaxing through a centrifugal machine to obtain the platycodon grandiflorum seed essential oil. The health product of the platycodon grandiflorum seed essential oil comprises 70 to 90% of platycodon grandiflorum seed essential oil, 8 to 28% of liquiritigenin extractive, and 2% of vitamin E. The method is high in oil yield of platycodon grandiflorum seed, green and safe, free of residual solvent, and simple and convenient, and realizes continuous industrial production. The health product of the platycodon grandiflorum seed essential oil has the effects of opening the inhibited lung-energy, expelling the phlegm to arrest coughing, and resisting inflammation.

Description

technical field [0001] The invention relates to the technical field of natural vegetable oils, in particular to a preparation method of bellflower seed essential oil and its bellflower seed oil composition and application. Background technique [0002] Bellflower seed is the seed of Platycodong grandiflorum (Jacq.) A.DC., a perennial herb of Campanulaceae (Campanulaceae). Platycodon grandiflorum has a long history of planting in my country, and it is one of the first batch of 60 items that are both food and medicine promulgated by the Ministry of Health. Bellflower essential oil is a fatty oil obtained by pressing or extracting dried and ripe bellflower fruits. The oil contains a variety of amino acids and a variety of essential trace elements, linoleic acid, bellflower saponins, bellflower polysaccharides, flavonoid glycosides, limonene, vitamins, etc. Platycodon grandiflora essential oil has medicinal effects on the human body such as expectorant, pus discharge, anti-infl...
