preparation example Construction

[0023] The invention provides a preparation method of citrus essential oil microcapsules, comprising the following steps:

[0024] (1) mixing chitosan quaternary ammonium salt with sodium alginate, acetic acid and water to obtain a composite wall material solution;

[0025] (2) mixing the composite wall material solution obtained in the step (1) with citrus essential oil and composite emulsifier, and emulsifying to obtain an emulsion;

[0026] (3) the emulsion obtained in the step (2) is mixed with an alkali, and a complex coagulation reaction is carried out to obtain the first product of the citrus essential oil microcapsules;

[0027] (4) mixing the first product of the citrus essential oil microcapsules obtained in the step (3) with calcium chloride, and carrying out a cross-linking curing reaction to obtain the citrus essential oil microcapsules.

[0028] Unless otherwise specified, the source of each component is not particularly limited in the present invention, and com...

Embodiment 1

[0067] (1) dissolving chitosan quaternary ammonium salt in an aqueous acetic acid solution with a mass concentration of 1% to obtain a chitosan quaternary ammonium salt solution; dissolving sodium alginate in distilled water to obtain a sodium alginate solution;

[0068] (2) Mix the chitosan quaternary ammonium salt solution and the sodium alginate solution to obtain a composite wall material solution (the mass ratio of chitosan quaternary ammonium salt and sodium alginate is 1:1, and the chitosan in the composite wall material solution is The total mass concentration of quaternary ammonium salt and sodium alginate is 2%);

[0069] (3) adding citrus essential oil, Tween-80 and Span-80 to the composite wall material solution obtained in step (2), emulsifying for 3min at 30000rpm and 25°C to obtain emulsion (citrus essential oil and composite wall material solution) The mass ratio of Tween-80 and Span-80 is 1:100, the mass ratio of Tween-80 and Span-80 is 1:1, and the mass ratio...

Embodiment 2

[0073] In the step (3) of Example 1, the mass ratio of the citrus essential oil and the composite wall material solution was replaced by 2:100, and other parameters were the same as those in Example 1 to obtain powdered citrus essential oil microcapsules.

Abstract

The invention provides a citrus essential oil microcapsule as well as a preparation method and application thereof, and belongs to the technical field of anticorrosion, wherein the preparation method comprises the steps: mixing chitosan quaternary ammonium salt with sodium alginate, acetic acid and water to obtain a composite wall material solution; and mixing with citrus essential oil and a compound emulsifier to obtain an emulsion, performing complex coacervation reaction, mixing with calcium chloride, and performing cross-linking curing to obtain the citrus essential oil microcapsule. The citrus essential oil is a natural bactericide and has an efficient, broad-spectrum and safe antibacterial effect; the prepared microcapsule is small in particle size, high in embedding rate and drug loading capacity and excellent in antibacterial performance, the core material can be slowly released in the using process to achieve the antibacterial effect, and the antibacterial effect time is prolonged. The result of the embodiment shows that the average particle size of the prepared citrus essential oil microcapsule is 340 nm, the embedding rate is 89.3%, the drug loading capacity is 44.65%, and the citrus essential oil microcapsule has excellent antibacterial performance on various bacteria and is good in antibacterial performance in a long time.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion, in particular to a citrus essential oil microcapsule and a preparation method and application thereof. Background technique [0002] Cosmetics occupy an important position in people's daily life. In order to ensure the stability of product performance, it must be added with antimicrobial substances, namely preservatives. With the advancement of scientific research, the society's research on preservatives has become more and more in-depth, and many traditional preservatives have been confirmed to have certain negative effects, which will affect human health. Therefore, "no added" preservative products are subject to market demand welcome. [0003] The non-volatile components of plant essential oils contain active substances that have excellent antioxidant, antiviral, antibacterial, and anti-inflammatory effects. Due to their naturalness and safety, they have been widely used in cosmetics, ...
