Embodiment 1

[0032] The preparation method of the slow-release plant essential oil and microcapsule powder thereof, the plant essential oil is prepared from the following raw materials in parts by weight: 85 parts of green tea, 5 parts of camphor leaves, 6 parts of vanilla pods and 4 parts of sandalwood leaves; Proportionally weigh the raw and auxiliary materials in the formula, add 30 times the amount of distilled water at 70°C, and separate the slow-release green tea essential oil through the method of rotating cone column. The fragrance retention time of green tea essential oil is 100h, which is about 160%.

[0033] Then β-cyclodextrin was selected as the wall material, and the mass ratio of green tea essential oil to wall material was 40, and the slow-release green tea essential oil microcapsule powder was prepared by spray drying method.

Embodiment 2

[0035] The preparation method of slow-release plant essential oil and microcapsule powder thereof, the plant essential oil is prepared from the following raw materials in parts by weight: 92 parts of tea tree flowers, 3 parts of camphor leaves, 4 parts of vanilla pods and 1 part of sandalwood leaves; Weigh the raw and auxiliary materials in the formula in proportion, add 30 times the amount of distilled water at 90°C, and separate and obtain the slow-release tea tree flower essential oil through atmospheric pressure steam distillation. Longevity is about 110% longer.

[0036] Then chitosan was selected as the wall material, and the mass ratio of plant essential oil to wall material was 30, and the slow-release tea tree flower essential oil microcapsule powder was prepared by spray drying.

Embodiment 3

[0038] The preparation method of the sustained-release plant essential oil and microcapsule powder thereof, the plant essential oil is prepared from the following raw materials in parts by weight: 95 parts of sweet-scented osmanthus, 2 parts of camphor leaves, 2 parts of vanilla pods and 1 part of sandalwood leaf; The raw and auxiliary materials in the formula are weighed in proportion, and the slow-release osmanthus essential oil is separated by pressing to obtain the fragrance retention time of the osmanthus essential oil for 70 hours, which is about 90% longer than that of ordinary osmanthus essential oil.

[0039] Then, gum arabic was selected as the wall material, and the mass ratio of the plant essential oil to the wall material was 15, and the slow-release osmanthus essential oil microcapsule powder was prepared by spray drying.

Abstract

The invention relates to a preparation method of a sustained release plant essential oil, which is prepared from raw materials through a plant essential oil extraction technology. The essential oil comprises the following raw materials in parts by weight: 60 to 98 parts of fragrant plants, 1 to 15 parts of yellow cinnamon leaf, 1 to 15 parts of vanilla pod, and 1 to 10 parts of santal leaf. The preparation method prepares the sustained release plant essential oil at a time, the perfume fixative is not added in the later period, and the using amount of artificially synthesized perfume fixative is reduced at the same time. The invention also relates to a preparation method of a sustained release plant essential oil microcapsule powder, which is prepared from the sustained release plant essential oil and a wall material by a microcapsule technology. The coupling microencapsulation technology further overcomes the problems of easy volatile property, instability, difficult storage and transportation, and bad water solubility of conventional plant essential oil, and thus has a good popularization and application value and market prospect.

Description

technical field [0001] The invention relates to the field of essential oil processing, in particular to a preparation method of slow-release plant essential oil and microcapsule powder thereof. Background technique [0002] With the deepening of people's research on aromatic plants, the sterilization and health care functions of plant aromatic essential oils have attracted more and more attention. and so on are constantly expanding. However, natural plant essential oils are mostly composed of phenols, alcohols, aldehydes, esters, terpene hydrocarbons and aromatic hydrocarbons, which are easily volatilized and oxidized by light, temperature, humidity, oxygen, etc., reducing the quality of essential oils. It brings great restrictions to the transportation, storage and application of essential oils. [0003] Deodorant, also known as deodorant or deodorant, is a spice with a longer-lasting aroma and slower volatilization in essence. Generally, the molecular weight is relative...
