Embodiment 1

[0043] A kind of golden bergamot essential oil microcapsule with bergamot essential oil as core material and β-cyclodextrin as wall material, its preparation method is:

[0044] Step 1: Weigh 10.00g of β-cyclodextrin, add 80ml of deionized water, stir in a water bath at 80°C to dissolve it, and obtain an aqueous solution of β-cyclodextrin; the material ratio of the β-cyclodextrin to deionized water For 1g: 8ml, cool to 50°C and keep warm for later use;

[0045] Step 2: Dissolving 2g of bergamot essential oil in absolute ethanol to obtain a golden bergamot essential oil solution; the volume ratio of the golden bergamot essential oil to absolute ethanol is 1:20;

[0046] Step 3: Add the obtained bergamot essential oil solution to the obtained β-cyclodextrin aqueous solution at a uniform speed and dropwise, stir while adding, and carry out the embedding reaction for 2 hours under the conditions of heating in a water bath at 50°C, protecting from light and sealing; After the reac...

Embodiment 2

[0058] The golden bergamot essential oil microcapsules and golden bergamot essential oil prepared in Example 1 were heated at 70°C to measure their slow-release properties, and the specific data are shown in Table 1:

[0059] Table 1 The effect of microencapsulation of bergamot essential oil on the volatilization rate of essential oil

[0060] Heating time / h

[0061] It can be seen from the above table that as the heating time prolongs, some essential oils of both the bergamot essential oil and the microcapsules will volatilize, but the volatilization rates of the two are different. .

Embodiment 3

[0063] The golden bergamot essential oil microcapsules obtained in Example 1 were subjected to a fragrance retention effect test, and the test steps were: dissolving the golden bergamot essential oil in ethanol to obtain a golden bergamot essential oil solution, and the golden bergamot essential oil microcapsules obtained in Example 1 And the golden bergamot essential oil solution was dried in an oven at 60°C, and the mass concentration of the essential oil was measured at different drying times. The specific data are shown in Table 2:

[0064] Table 2 Changes in the mass concentration of essential oils at different drying times

[0065] Drying time / h

[0066] It can be seen from the above table that as the drying time prolongs, the concentration of the essential oil in the golden bergamot microcapsules is much stronger than that of the unembedded essential oil.

Abstract

The invention provides toothpaste containing citrus bergamot essential oil microcapsules and a preparation method of the toothpaste. The preparation method of the citrus bergamot essential oil microcapsules includes the steps: 1 dissolving beta-cyclodextrin in water to obtain beta-cyclodextrin water solution; 2 dissolving citrus bergamot essential oil in organic solvents to obtain citrus bergamotessential oil solution; 3 adding the obtained citrus bergamot essential oil solution into the obtained beta-cyclodextrin water solution, performing embedding reaction under the conditions of heating,light resistance and sealing, placing reaction liquid into a refrigerator for refrigeration after reaction, and performing vacuum filtration and drying to obtain the citrus bergamot essential oil microcapsules. The citrus bergamot essential oil is embedded and further added into the toothpaste, provides the sensory experience of strong tangerine fragrance in a product and has antibacterial effects.

Description

technical field [0001] The invention belongs to the field of daily chemicals and relates to a toothpaste, in particular to a calcium carbonate toothpaste containing microcapsules of bergamot essential oil and a preparation method thereof. Background technique [0002] At room temperature with a slightly higher temperature, the essential oil is extremely volatile, its stability is poor, and the fragrance retention time is short, which affects the quality added to the product and greatly limits the application of the essential oil. Encapsulation of essential oils using microencapsulation technology has become a hot research topic in recent years. Through microencapsulation, the volatilization of the essential oil is suppressed due to the sealing effect of the wall material, and the aroma remains intact, thereby prolonging the storage time of the essential oil and improving the slow-release effect of the essential oil, with stability. Therefore, it is necessary to carry out re...
