example 1

[0032] A kind of release controlled-release nano alcoholosome rose essence, calculated in parts by weight (percentage by weight):

[0033]

[0034] The preparation of the above-mentioned release-controlled release nano-alcohol plastid rose essence specifically comprises the following preparation steps:

[0035] 1) Add 0.8 parts by weight of Tween-80 and 2 parts by weight of rose essential oil dropwise into 30 parts by weight of absolute ethanol to dissolve evenly and set aside;

[0036] 2) Dissolving 0.2 parts by weight of sucrose ester and 2 parts by weight of soybean lecithin in the above ethanol solution for use;

[0037] 3) Put the above-mentioned step 2) absolute ethanol solution into a sealed glass Erlenmeyer flask, and fully stir for 2 minutes at 30°C with a rotation speed of 1000r / min;

[0038] 4) Slowly add 60 parts by weight of water to the above-mentioned sealed absolute ethanol solution dropwise while maintaining a rotation speed of 1000 r / min at 30°C;

[0039...

example 2

[0047] According to the preparation method of Example 1, the rose essential oil was replaced with violet essential oil, and the other parts by weight remained unchanged. The particle size of the ethosome nano violet essence was detected by the Malvern laser particle size analyzer to be 64.31 ± 1.87, and the zate potential was 25.1 ± 0.38 .

[0048] Comparison of slow-release ethosome nano-violets dropped on professional smelling paper and the control group through sensory evaluation, GC-MS, and electronic nose detection:

[0049] The effect of ethosome nano violet essential oil appeared after one hour of release under normal temperature, and the total retention rate of aroma was 39.8% higher than that of the control group after four hours of release, and the release was extended for at least two hours, and the aroma was comfortable.

example 3

[0051] A kind of release controlled-release nano alcoholosome rose essence, calculated in parts by weight (percentage by weight):

[0052]

[0053] The preparation of the above-mentioned release-controlled release nano-alcohol plastid rose essence specifically comprises the following preparation steps:

[0054] 1) Add 0.9 parts by weight of Tween-80 and 6 parts by weight of rose essential oil dropwise into 35 parts by weight of absolute ethanol to dissolve evenly and set aside;

[0055] 2) Dissolving 0.1 parts by weight of sucrose ester and 2 parts by weight of soybean lecithin in the above absolute ethanol solution for use;

[0056] 3) Put the above absolute ethanol into a sealed glass Erlenmeyer flask, and fully stir for 4 minutes at 20°C with a rotation speed of 1500r / min;

[0057]4) Slowly add 56 parts by weight of water dropwise into the above-mentioned sealed anhydrous ethanol solution while maintaining a rotation speed of 1500 r / min at 20°C;

Abstract

The invention provides a controlled release type nanometer ethosome essence. The controlled release type nanometer ethosome essence comprises a vesicle structure, the vesicle structure has a lipid bilayer structure and comprises soya bean lecithin, ethyl alcohol and water, a vesicle core is an essential oil, and a stabilizer sucrose ester and an emulsifier Tween-80 are added in the preparation; the controlled release type nanometer ethosome essence delays the release of the fragrance, the fragrance holding time is prolonged, the stability of an essence system is improved, meanwhile, the range of application of the essence is expanded, and the invention further discloses a preparation method of the controlled release type nanometer ethosome essence.

Description

Technical field: [0001] The invention belongs to the field of flavors, and in particular relates to a release-controlled release nano-alcohol body flavor and a preparation method thereof. Background technique: [0002] With the development and extension of microcapsule technology, nano-microcapsules have been widely concerned. Nanotechnology has been gradually researched and applied in food, medicine, skin care products, etc. Nano-solution medicine and nano-granulation technology have also been applied. Essence is a volatile additive that is used in food, medicine, cosmetics, etc. Ordinary flavors are ordinary emulsions, which are thermodynamically unstable systems with large particles in the dispersed phase, which are prone to stratification and oil slicks, and the flavor system is easily damaged, resulting in a decline in product quality. Invention content: [0003] The purpose of the present invention is to provide a release-controlled nano-alcohol essence that can de...
