Problems solved by technology

Today, most daily chemical and edible products are still using traditional methods for adding aroma and fixing aroma. Although the operation is simple, due to the characteristics of flavors and fragrances that are volatile and easy to oxidize, the aroma is difficult to be stable and long-lasting, which directly affects the quality of the product. grade and quality
In order to protect flavors from environmental influences, mask bad flavors, reduce volatility, protect sensitive components, and control release, researchers have developed microcapsule flavors. The commonly used methods for preparing flavor microcapsules are: spray drying method, extrusion method, Complex coacervation method and interface polymerization method, spray drying method requires a large spray drying tower, and the high drying temperature in the spraying process leads to high production costs and loss of some flavors; the price of extrusion equipment used in extrusion method is very expensive At present, only a few large-scale foreign manufacturers have adopted this method; while the process of complex coacervation and interfacial polymerization is complex, with many steps, and involves technical problems of process amplification, in addition to the need for pH adjustment and removal of curing agents (such as Glutaraldehyde) and solvents, particle separation steps, etc., and the environmental protection issues brought by the entire production process must also be considered, so the actual production cost is very high

Embodiment 1

[0023] Flower essence and polyethylene glycol with molecular weight of 6000 are selected, and the weight ratio of flower essence and molecular weight is 5:95. Heat the polyethylene glycol to 60-80°C to melt, add flower essence to the melted polyethylene glycol, stir while adding to form a uniform flower essence-polyethylene glycol blend, cool naturally or at 4°C After accelerated cooling to room temperature, grind and pass through a 300-mesh sieve to obtain co-melt powder.

[0024] The co-melt powder obtained in this example has a characteristic aroma of typical flower essence, and the essence exists in the co-melt in the form of nanometers, and the aroma is stable.

[0025] Dissolve the co-melt powder obtained in this example in water, and let it stand to form a nano-colloid solution with the co-melt obtained in this example as a solute. The colloid solution is dropped on a mica sheet and dried naturally, then scanned and observed with an atomic force microscope. figure 1 is...

Embodiment 2

[0027] The difference between this embodiment and embodiment 1 is that the weight ratio of flower essence and molecular weight is 10:90.

[0028] The eutectic powder obtained in this embodiment is dissolved in water, and left to stand to form a nano-colloid solution with the eutectic obtained in this embodiment as a solute, and the solute in the nano-colloid solution (that is, the co-melt obtained in this embodiment) is measured by the dynamic light scattering method. melt) diameter distribution, figure 2 is the obtained diameter distribution curve. From figure 2 It can be seen that the size of the eutectic particles obtained in this example in the colloidal solution is about 50nm-250nm.

Embodiment 3

[0030] The difference between this example and Example 1 is that: the weight ratio of flower essence and molecular weight is 15:85; the molecular weight of polyethylene glycol is 6000.

[0031] The eutectic powder obtained in this example is dissolved in water to form a nano-colloid solution, and the particle size of the colloid particles ranges from 50 nm to 250 nm as tested by a laser particle size analyzer and an atomic force microscope.

[0032] Apply gas chromatography-mass spectrometry (GC-MS) to analyze respectively the flower essence used in this embodiment and the co-melt powder obtained in this embodiment, the results are shown in image 3 , image 3 Curve 1 is the spectral line of the flower essence used in this embodiment, and curve 2 is the spectral line of the co-melt powder obtained in this embodiment. Comparing curve 1 and curve 2, it can be known that the nano-essence dispersion of the present invention will not affect the composition of the essence. Changes ...

Abstract

The invention provides a nanometer essence dispersoid, which comprises essence and polyethylene glycol. The nanometer essence dispersoid is a eutectic substance formed by the essence and the polyethylene glycol according to weight proportion of between 1 to 99 and 15 to 85. The invention also provides a method for preparing the nanometer essence dispersoid, which is to evenly mix the essence and the melted polyethylene glycol according to the weight proportion of between 1 to 99 and 15 to 85. The nanometer essence dispersoid is the eutectic substance formed by the essence and the polyethyleneglycol, has the advantages of stable and sustained fragrance, steady scent and good water-solubility. The polyethylene glycol is a high molecular polymer with no toxicity and excellent biocompatibility, has stable chemical property, does not generate chemical reaction with the essence, and does not destroy the characteristic fragrance of the essence. The method has the advantages of simple process, convenient implementation and low cost, and is convenient for industrial production. The preparation process can not cause essence volatilization, and uses safe and non-toxic raw materials, so no pollution is generated during the production.

Description

technical field [0001] The invention relates to a fragrance, in particular to a nano essence dispersion with long-lasting fragrance, simple preparation process and low cost and a preparation method thereof. Background technique [0002] Flavor is the "soul" of the food, tobacco and daily chemical industries, and it plays a vital role in the quality and variety of flavored products. With the improvement of living standards, people have higher and higher requirements for the quality of food and daily necessities. The development of industry and the pull of consumer goods have accelerated the development of the world's flavor industry. The market demand for flavors and the quality requirements for flavored products are increasing. Constantly increasing. Today, most daily chemical and edible products are still using traditional methods for adding aroma and fixing aroma. Although the operation is simple, due to the characteristics of flavors and fragrances that are volatile and ...
