Problems solved by technology

In this process, the fruit stones are directly crushed after being dried. Since the fruit stones of Cornus officinalis are relatively hard, it is difficult to crush them; solvent extraction is easy to cause organic solvent residues, which may have little effect on crude oil substances, but if used for the preparation of perfume , will introduce miscellaneous gas, which will seriously affect the quality of perfume

Embodiment 1

[0030] The present invention extracts the technique of perfume from the cornus officinale core, and the steps are as follows:

[0031] ① Raw material pretreatment: choose high-quality dogwood kernels without mold, as raw materials, rinse with clean water, remove the soil and sand outside the dogwood kernels, and control the moisture after rinsing;

[0032] ②Drying: Put the cornus officinalis that has been dehydrated into a drying oven at 50°C, control the temperature, and keep turning to remove moisture. The drying time is controlled at 23 minutes;

[0033] ③ Freezing: Place the dried Cornus officinalis in a freezer at -5°C for 1.8 hours, until the inner cells in the Cornus officinalis undergo physical changes;

[0034] ④ Pulverization: immediately pulverize the frozen Cornus officinalis nucleus, and pulverize it to a fine powder with a diameter of 80 meshes;

[0035] ⑤ Distillation: Put the fine powder of Cornus officinalis obtained after crushing into the distillation devic...

[0038] The present invention extracts the technique of perfume from the cornus officinale core, and the steps are as follows:

[0039] ① Raw material pretreatment: choose high-quality dogwood kernels without mold, as raw materials, rinse with clean water, remove the soil and sand outside the dogwood kernels, and control the moisture after rinsing;

[0040] ②Drying: put the cornus officinalis that has been dehydrated into a drying oven at 54°C, control the temperature, and keep turning to remove moisture. The drying time is controlled at 22 minutes;

[0041] ③ Freezing: place the dried Cornus officinalis in a freezer at -4°C for 1.9 hours, and wait for the internal cells in the Cornus officinalis to undergo physical changes;

[0042] ④ Pulverization: immediately pulverize the frozen Cornus officinalis nucleus, and pulverize it into a fine powder with a diameter of 90 mesh;

[0043] ⑤ Distillation: Put the fine powder of cornus officinalis obtained after crushing into the disti...

Embodiment 3

[0046] The present invention extracts the technique of perfume from the cornus officinale core, and the steps are as follows:

[0047] ① Raw material pretreatment: choose high-quality dogwood kernels without mold, as raw materials, rinse with clean water, remove the soil and sand outside the dogwood kernels, and control the moisture after rinsing;

[0048] ②Drying: put the cornus officinalis that has been dehydrated into a drying oven at 58°C, control the temperature, and keep turning to remove moisture. The drying time is controlled at 20 minutes;

[0049] ③ Freezing: Place the dried Cornus officinalis in a freezer at -2°C, freeze for 2.1 hours, and wait for the internal cells in the Cornus officinalis to undergo physical changes;

Abstract

The invention discloses a process for extracting perfume from dogwood nucleuses. The process comprises the following steps: preprocessing dogwood as a raw material, drying, refrigerating, grinding and distilling. According to the process, the extraction rate of spice substances in the dogwood is 57.9%-65.5%; the obtained perfume contains more than 60 flavor components and is easy to store, unique in aroma, specially aromatic, good in smell and free of any odor and is easily accepted by people, the oleic acid value is 17.5-18.8, side effects cannot be caused to skin, the aroma can be kept for a long time, and the perfume can serve as a chemical product and a food additive after being separated and purified.

Description

technical field [0001] The invention belongs to the technical field of perfume preparation, and in particular relates to a process for extracting perfume from cornus officinalis. Background technique [0002] At present, the main part of perfume is chemical synthesis. Although there are many kinds of natural fragrance types of perfume, they still cannot be compared with the number of synthetic fragrances. [0003] The weight ratio of dogwood flesh and core is about 3:7. So far, only the outer red "skin" of dogwood fruit is used in the pharmaceutical industry, and the "core" of dogwood fruit is regarded as a "waste" material with no medicinal value Throwing away, a large number of dogwoods are discarded on the roadside and in the river ditches. Dogwood pits can be seen everywhere in front of and behind the doors of farmers who produce dogwood, which is very indecent and pollutes the environment. Cornus officinalis is known to contain more than 70 effective components, some o...
