[0032] The preparation method of above-mentioned heat-resistant slow-release type sweet-scented osmanthus essence microcapsules, such as figure 1 shown, including the following steps:

[0033] Step 1. Dissolve the modified gum arabic A-2010 and maltodextrin of the formula in deionized water, and stir evenly at room temperature to obtain a wall material solution, wherein the mass ratio of modified gum arabic A-2010 to deionized water is 1~3:10;

[0034] Step 2. Add the oil-soluble sweet-scented osmanthus essence of the formula into the wall material solution prepared in step 1, stir at room temperature at a stirring rate of 100r / min-500r / min for 10-30min, mix evenly, and form a suspension;

[0035] Step 3. Spray-dry the suspension prepared in Step 2 through a spray dryer, wherein the inlet air temperature is 170-190°C, and the outlet air temperature is 80-90°C;

[0036] Step 4, the spray drier is cooled to room temperature to obtain powdered heat-resistant slow-release osmant...

Embodiment 1

[0039] 1. Weigh 16.62g of modified gum arabic A-2010, 16.63g of maltodextrin, and 65.00g of deionized water into a beaker, heat in a water bath at 25°C, and stir evenly, as a wall material solution;

[0040] 2. Weigh 1.75g ​​of oil-soluble sweet-scented osmanthus essence, add it to the wall material solution, heat in a water bath at 25°C, and stir at 300r / min to form a suspension evenly;

[0041] 3. Spray-dry the suspension, the air inlet temperature is 180°C, the outlet air temperature is 90°C, and the feeding rate of the peristaltic pump is 30r / min;

[0042] 4. After the spray dryer is cooled to room temperature, heat-resistant slow-release sweet-scented osmanthus essence microcapsule powder is obtained. The particle size distribution of the microcapsule powder is 3.6-13.4 μm as measured by a scanning electron microscope. 87.92% (heat treatment at 120°C for 30 minutes in an electric thermostat, measure the absorbance of the sample before and after heat treatment, and calcula...

Embodiment 2

[0044] 1. Weigh 10.28g of modified gum arabic A-2010, 15.43g of maltodextrin, and 70.00g of deionized water into a beaker, heat in a water bath at 25°C, and stir evenly, as a wall material solution;

[0045] 2. Weigh 4.29g of oil-soluble sweet-scented osmanthus essence, add it to the wall material solution, heat in a water bath at 25°C, and stir at 300r / min to form a suspension evenly;

[0046] 3. Spray-dry the suspension, the air inlet temperature is 180°C, the outlet air temperature is 90°C, and the feeding rate of the peristaltic pump is 30r / min;

[0047] 4. After the spray dryer is cooled to room temperature, heat-resistant slow-release sweet-scented osmanthus essence microcapsule powder is obtained. The particle size distribution of the microcapsule powder is 4.2-15.4 μm as measured by a scanning electron microscope. 82.20%, 92.28% of osmanthus flower aroma retention rate after storage at 20°C for three months.

Abstract

The invention discloses a heat-resisting sustained release type osmanthus fragrans essence microcapsule. The heat-resisting sustained release type osmanthus fragrans essence microcapsule comprises the following components in percent by mass except moistures: 5-25% of oil-soluble osmanthus fragrans essence, 25-48% of modified Arabic gum A-2010 and 37-63% of maltodextrin, wherein a DE (Dextrose Equivalent) value of the maltodextrin is 15-20. The invention further provides a preparation method of the heat-resisting sustained release type osmanthus fragrans essence microcapsule, and an application of the heat-resisting sustained release type osmanthus fragrans essence microcapsule in preparation of cosmetics. The heat-resisting sustained release type osmanthus fragrans essence microcapsule prepared by the invention has good stability and water solubility; the frangrance retention rate at high temperature reaches 85%; three-month frangrance retention rate reaches 90%; the heat-resisting sustained release type osmanthus fragrans essence microcapsule has the advantages of higher heat resistance and better release property, can be applied to the cosmetics containing the oil-soluble osmanthus fragrans essence, and has better compatibility of skin. The preparation method provided by the invention has the advantages of simplicity of controllability and high repeatability.

Description

technical field [0001] The invention relates to the technical field of essence microcapsules, in particular to a heat-resistant slow-release osmanthus essence microcapsule and a preparation method and application thereof. Background technique [0002] Adding fragrance to daily cosmetics or skin care products is a hot spot in the development of the global cosmetics industry in recent years. The essence added to skin care cosmetics is generally oil-soluble essence, and its main component is volatile oil, which is very unstable in nature and difficult to store, store and add. [0003] Carrier technology can improve the compatibility, stability and sustained release of flavors. Researchers at home and abroad have turned their attention to carrier technology and developed carrier transport systems such as microcapsules, liposomes, and gels. Microcapsule technology is a technology that coats solid or liquid with film-forming materials to form tiny particles. Microcapsules can sto...
