Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bath additive containing fine powder of natural yuzu as a main ingredient, which quickly dissolves when added to a hot water bath and has the elegant properties of natural yuzu. To provide a bath additive that preserves the fragrance and ingredients effective for the human body.

(Prior art) Generally speaking, in our country, on the winter solstice, there is a custom of slicing a yuzu fruit, stuffing it into a cloth bag, and hanging it in a bathtub to take a bath. In addition to warming the body from the core, it also smoothes the skin, so it has been said to be effective for treating cracks, red spots, wrinkles, etc.

It is also said that roasting yuzu seeds, drinking hot water, and then taking a yuzu bath is effective against neuralgia, rheumatism, sensitivity to cold, etc.

(Problems to be Solved by the Invention) As is well known, yuzu is an oblate, bright yellow fruit with an average weight of about 110 to 130 g, but its juice contains about 9% citric acid and has a sour taste. The pulp has a pale yellow color and contains 150 mg of vitamin C and 1,300 units of carotene (Calβ, γ-carotene is a precursor of vitamin A), and its peel is mainly composed of limonene, a monoterpene. It contains 0.1 to 0.3% of essential oil (aromatic volatile oil).

Therefore, yuzu contains essential oil, which is the main source of its fragrance, as well as
Since it contains many nutritionally important ingredients such as vitamin C and carotene, as well as other effective ingredients such as citric acid, it can be seen that if it is used as a bath additive, it will have excellent effects.

However, Nagamu Yuzu is extremely difficult to store, so
Except for being shipped all at once to the market during the harvest season from late March to December, the current situation is that it is hardly available during other seasons.

In addition, the skin of green fruits is used as a flavoring agent, the pulp of mature fruits is used as an ingredient for cooking and confectionery, and the juice is used separately in hot pots and vinegared dishes. In any case, only a portion of the yuzu was used, not the whole yuzu.

On the other hand, recently, bath salts with the scent of yuzu have been developed, but since they all use synthetic fragrances, their scent is not as elegant and strong as the scent of natural yuzu. It is hard to avoid feeling sticky, and having an unnatural sense of smell.

Furthermore, since this bath additive uses synthetic fragrance, it naturally does not contain the above-mentioned active ingredients unique to natural yuzu, and therefore cannot exhibit the bathing effect corresponding to that of natural yuzu.

(Means for Solving the Problems) The present invention is intended to solve the above-mentioned problems, and allows the whole yuzu to be used throughout the year regardless of the season. This invention was completed as a result of research with the aim of preserving the entire yuzu without damaging it.The feature is that the yuzu is roughly crushed or squeezed, and then immersed in liquid nitrogen to extract the yuzu components. This bath additive contains fine yuzu powder as the main ingredient, which is obtained by flash freezing and pulverizing the frozen product to a size of 8 (mesh) or less in a nitrogen gas atmosphere at a temperature of -50° C. or below.

(Manufacturing process of yuzu fine powder) An example of the manufacturing process of yuzu fine powder, which is the main component of the bath additive of the present invention, will be described below.

First, the harvested yuzu is washed with water to remove foreign substances and things attached to the fruit skin, and after draining, it is crushed by a coarse crusher of about 2 to 3 cI.
Crush into 12 pieces of size 11.

Then, the coarsely crushed yuzu pieces are flash frozen by immersing them in liquid nitrogen with a boiling point of -196°C (normal pressure), and then ground into a fine powder of 80 mesh or less in a nitrogen gas atmosphere at -50°C.

In this case, the yuzu is immersed in liquid nitrogen at an extremely low temperature of -196°C, so it becomes extremely brittle due to low-temperature brittleness, and all parts of the fruit, including the peel, pulp, and seeds, can be easily pulverized. can.

In other words, the differentiated yuzu powder of the present invention does not exhibit low-temperature brittleness even when frozen by normal freezing methods, for example, at a low temperature of about -40°C, so it is natural to pulverize yuzu into fine powder. .

Furthermore, throughout this pulverization process, the yuzu component was -5 (
Since the yuzu is placed in an inert nitrogen gas atmosphere at a temperature of This also eliminates the possibility of decomposition of components.

Examples of bath additives containing the yuzu fine powder obtained in the above steps will be described below.

(Example 1) Bath additives are manufactured by using the fine powder of natural yuzu produced by the above manufacturing method as it is or by blending it with borax, thickeners, alcohols, and other additives as necessary. death,
When you dissolve approximately 50 to 300 g of natural yuzu and disperse it evenly in a normal home bath, the elegant scent of natural yuzu wafts into the bathroom, relaxing your tired nerves, improving blood circulation and warming your body enough to prevent cracks. It is effective against , akagire, skin discoloration, as well as neuralgia, etc.

(Example 2) To the above bath additive, less than 5% by weight of squalane and natural vitamin E obtained by hydrogenating squalene, which is contained in large amounts in the liver oil of deep-sea sharks such as merganser shark and flatfish shark, are each added in an amount of 5% or less by weight. Blend.

The above-mentioned squalane is an essential nutritional component of human skin, and vitamin E, a natural antioxidant, is also effective in promoting skin cell metabolism, so by incorporating these into bath additives, the efficacy of yuzu fine powder can be enhanced. In addition, it keeps your skin moisturized,
It is possible to more effectively prevent red spots, stain discoloration, etc.

(Example 3) Into the bath additive shown in Example 1, vegetable oils such as olive oil, cottonseed oil, and soybean oil, and other ingredients beneficial to the skin such as medicinal herbs are added in an amount of 5% or less by weight.

This bath salt is also suitable for body massage and is effective in treating various conditions such as neuralgia and rheumatism, in addition to the effects of fine yuzu powder.

(Example 4) A small amount of alkali metal salts of higher fatty acids, such as sodium stearate, sodium oleate, sodium lylphate, etc., were added to the bath additives of Examples 1 to 3 to improve the dispersibility and floatation of bath water. It enhances the skin's ability to cleanse the skin effectively.

(Effects of the invention) As mentioned above, since the main ingredient of the personal bath additive is fine powder obtained by freezing and crushing natural yuzu using liquid nitrogen, all you need to do is spray the bath additive into a hot water bath. dissolves quickly,
You can easily create a yuzu bath.

In addition, since the yuzu is immersed in liquid nitrogen to obtain a fine powder, the whole yuzu fruit can be made into a fine powder instead of just using a portion of the yuzu as in the past, and the whole yuzu can be used at once. The active ingredients and aromatic components contained in the peel, pulp, and juice can be preserved.

Therefore, the personal bath salts can retain the elegant scent of natural yuzu without impairing it, so when you take a bath, the strong fragrance of yuzu will soothe tired nerves, improve blood circulation, and warm your body from the core. can.

What's more, since the personal bath additives are made with natural yuzu as an ingredient, the active ingredients contained in the yuzu fruit, such as vitamin C1, citric acid, and essential oils, activate skin cells and prevent wrinkles, cracks, etc. It is effective against red rash, etc., and is also effective against neuralgia, rheumatism, etc.

Furthermore, as mentioned above, since the entire natural yuzu is processed into a fine powder using liquid nitrogen, it is possible to preserve it through a portion of it, and its use is not limited to the yuzu harvesting season, as was the case in the past, but can be used in all seasons. By using this product, you can easily enjoy the unique flavor of a yuzu bath, and you can make it into a household bath salt that is extremely suitable in terms of both quality and efficacy.
