Problems solved by technology

Due to the small size of nanocapsule particles, it is easy to disperse and suspend in water to form a colloidal solution, which is clear and transparent in appearance and has unique properties different from ordinary microcapsules. The literature and patents on the preparation of compound flavors by capsule technology have not yet been reported

Embodiment 1

[0033] Example 1 Preparation of nano-rose-ambergris-sandalwood composite essence

[0034] Add 250mg of chitosan, 0.75g of glacial acetic acid and 100g of deionized water into a 200ml beaker, and after ultrasonic degradation, chitosan is completely dissolved in glacial acetic acid to obtain a transparent and uniform solution; 25mg of sodium tripolyphosphate Dissolve in 100g of deionized water, then add 1g of Tween-20 as a solubilizer, 0.4g of rose-ambergris-sandalwood compound essence, and stir well to obtain a transparent and uniform sodium tripolyphosphate system; then transfer this system to acid formula In the burette, under the effect of magnetic stirring, drip into the dissolved chitosan solution at a rate of 1 drop (0.02ml-0.03ml) every 3 seconds. After ion coagulation, the reaction was completed, and the solution was found to be clear with a faint blue light, but the blue light phenomenon was not very obvious. It shows that the system contains a certain amount of nanoc...

[0035] Example 2 Preparation of nano-rose-ambergris-sandalwood composite essence

[0036] Add 250mg of chitosan, 0.75g of glacial acetic acid and 100g of deionized water into a 200ml beaker, and after ultrasonic degradation, chitosan is completely dissolved in glacial acetic acid to obtain a transparent and uniform solution; 25mg of sodium tripolyphosphate Dissolve in 100g of deionized water, then add 1g of Tween-80 as a solubilizer, 0.4g of rose-ambergris-sandalwood compound essence, and stir well to obtain a transparent and uniform sodium tripolyphosphate system; then transfer this system to acid formula In the burette, under the effect of magnetic stirring, drip into the dissolved chitosan solution at a rate of 1 drop (0.02ml-0.03ml) every 3 seconds. After ion coagulation, the reaction was completed, the solution was found to be clear, the blue light phenomenon was obvious and the system existed stably. After testing by the laser particle size analyzer, the results are con...

[0037] Example 3 Preparation of nano-rose-ambergris-sandalwood composite essence

[0038]Add 400mg of chitosan, 0.6g of glacial acetic acid and 100g of deionized water into a 200ml beaker, and after ultrasonic degradation, chitosan is completely dissolved in glacial acetic acid to obtain a transparent and uniform solution; 75mg of sodium tripolyphosphate Dissolve in 100g of deionized water, then add 1g of Tween-80 as a solubilizer, 0.4g of rose-ambergris-sandalwood compound essence, and stir well to obtain a transparent and uniform sodium tripolyphosphate system; then transfer this system to acid formula In the burette, under the effect of magnetic stirring, drip into the dissolved chitosan solution at a rate of 1 drop (0.02ml-0.03ml) every 3 seconds. After ion coagulation, the reaction was completed, and the solution was found to be clear, and the blue light phenomenon was obvious. But after standing for a period of time, white flocs will be produced in the solution, which p...

Abstract

The invention discloses a nanometer rose-ambergris-sandalwood composite essence, which is composed of the following components: 0.4 (weight parts) rose-ambergris-sandalwood composite essence, 0.15-0.4 (weight parts) chitosan , 0.025-0.075 (weight parts) sodium tripolyphosphate, 0.225-0.7 (weight parts) glacial acetic acid, 1.0 (weight parts) solubilizer, 200 (weight parts) deionized water. The nano rose-ambergris-sandalwood composite essence prepared by the invention has clear solution, obvious blue light phenomenon, and the system can exist stably. After the laser particle size analyzer and scanning electron microscope test, the prepared nano-rose-ambergris-sandalwood composite essence has a relatively uniform particle size distribution, the particle size is about 100nm, and the aroma is stable.

Description

technical field [0001] The invention relates to a composite essence, more specifically relates to a nanometer rose-ambergris-sandalwood composite essence prepared by nanocapsule technology. Background technique [0002] The concept of nanocapsules was first proposed by Narty et al. in the late 1970s. Due to the unique properties of nanocapsules, it has been applied in many fields. Especially in the research of drug nanocapsules, it has been found that it has good targeting and sustained release effects. With the in-depth development of microcapsule technology, a variety of techniques for preparing nanocapsules have emerged, mainly including emulsion polymerization, interfacial polymerization, dry bath method, layer-by-layer nano self-assembly method and electrostatic spraying method. Due to the small size of nanocapsule particles, it is easy to disperse and suspend in water to form a colloidal solution, which is clear and transparent in appearance and has unique properties ...
