Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a water-soluble fragrance containing natural essential oil as a main fragrance.

Conventional technology Natural essential oils have better retention properties than flavors and essences, and are strong fragrances, and are used as additives in various beverages, desserts, confectioneries, and even cosmetics and pharmaceuticals. It is a wide range of fragrances.

However, all natural essential oils are difficult to dissolve in cold water, so unless the substance to be added is oil-based, it is best to add an emulsifier or stabilizer and emulsify and disperse using a high-pressure emulsifier. It's normal. In this case, natural products such as gum arabic, sucrose fatty acid esters, and natural resins are used as emulsion stabilizers for safety reasons, but these emulsion stabilizers do not stabilize the emulsified natural essential oil. The properties were not always sufficient, and when stored for a long period of time, the oil layer sometimes separated.

Problems to be Solved by the Invention In view of the fact that conventional water-based fragrances based on natural essential oils had the above-mentioned drawbacks, the present invention provides a water-soluble fragrance that has excellent stability and does not cause oil phase separation over a long period of time. It is intended to provide fragrance.

Means for Solving the Problems The present invention solves the above problems by solubilizing natural essential oils using saponin.

Saponin is a type of steroid or terpene glycoside that widely exists in the plant kingdom, and its sugar components include gluten,
(Lactose, arabic acid, uronic acid, etc.) The saponin contained in the water-soluble fragrance of the present invention as a solubilizing agent is
Plant tissues containing saponins, such as Quillaya (Qui
The bark of Sapindium sapinata (S. 5aponaria),
apinclus mukurossi), saponaria officinalis
L, ) root, tea (Thea 5inensis L,)
A saponin-containing extract obtained from the fruit of a tree may be used, but it is better to use purified saponin obtained by treating it with activated carbon, adsorption resin, etc., since it has less effect on the aroma of natural essential oils and is less colored. , is advantageous.

To produce the water-soluble fragrance of the present invention, the amount of natural essential oil to be solubilized is usually 0.5 to 10 times (preferably 1 to 1 times) the amount of natural essential oil to be solubilized.
5 times the amount) of saponins as a 0.1 to 40% aqueous solution (preferably a 1 to 30% aqueous solution), and while stirring,
Add some natural essential oil to it. In that case, surfactants other than saponins, stabilizers, saccharides, amino acids, and other components necessary as flavoring agents may be added to the saponin aqueous solution within a range that does not interfere with the solubilization effect.

In the water-soluble fragrance of the present invention, natural essential oils are solubilized by the solubilizing action of saponins, as described above.
As a result, the entire water-soluble fragrance is in the form of a transparent aqueous solution. This solubilized liquid has much better stability than conventional natural essential oil emulsions using natural surfactants, and also has excellent resistance to heating, pH changes, dilution, etc.

Therefore, the water-soluble fragrance of the present invention is an excellent fragrance that can withstand longer storage than conventional emulsified natural essential oil-based fragrances and can be easily and uniformly mixed into a wide range of foods, drinks, medicines, etc. Natural essential oils can now be used as fragrances even in fields where it was difficult to use them.

Canada The present invention will be explained below with reference to Examples.

Example 1 10 g of natural perilla oil was added dropwise to 90 g of 75% high-fructose corn syrup containing 20% Quillaja saponin while stirring, and the stirring was continued to obtain a reddish-brown transparent solution in which perilla oil was solubilized.

This solubilized liquid remained almost transparent even when diluted 500 times with water, and had a good aroma.

Example 2 50 g of 75% high-fructose corn syrup, 25 g of Quillaya saponin, 5 g of Sanso 7) No. 681C (succinic acid monoglyceride: Taiyo Kagaku) were heated to 60°C and mixed uniformly, and 25 g of natural lemon oil was added dropwise to this. While stirring, the whole mixture was stirred and mixed using a homomixer. This resulted in a yellow-brown, almost transparent solution in which the lemon oil was solubilized.

When this solubilized liquid was diluted 500 times with water, it became slightly milky white, but no separation of the oil layer was observed. Further, this diluted solution showed no change at all even when its pH was lowered to 4 with citric acid, and was stable even when it was heated to 90° C. for 30 minutes and then cooled to room temperature.

Example 3 75% starch syrup 50g 1 Muclodisaponin 20g, sample 7) 5g of Q-18B (polyglycerin fatty acid ester; Taiyo Kagaku) were heated to 60°C and mixed uniformly, and 25g of natural orange oil was added dropwise to this. The whole mixture was stirred and mixed using a homomixer. This resulted in a yellow-brown, almost transparent solution in which the orange oil was solubilized.

When this solubilized liquid was diluted 500 times with water, it became slightly milky white, but no separation of the oil layer was observed. Further, this diluted solution showed no change at all even when its pH was lowered to 4 with citric acid, and was stable even when it was heated to 90° C. for 30 minutes and then cooled to room temperature.
