Method for manufacturing soap containing supercritical fluid pine nut extract and soap manufactured by the method {Manufacturing method of soap containing supercritical fluid pine nut extract and soap thereby}

The present invention relates to a method for producing soap containing pine nut extract in a supercritical fluid and to soap manufactured by the method. More specifically, the present invention relates to a method for producing soap containing pine nut extract in a supercritical fluid, and more specifically, to a method for extracting pine needles and pine needles with a fluid in a supercritical state and containing oil-based phytoncide and water-soluble phytoncide. By preparing a pine nut solution, mixing the fat, oil, and saponification reaction components and proceeding with the saponification reaction, soap is produced. It can provide excellent antibacterial, anti-inflammatory and antioxidant effects, and can provide the unique scent of pine needles. A soap manufacturing method containing supercritical fluid pine nut extract, which can have excellent phytoncide sustained release properties and greatly improve the rancidity stability of soap and the color change stability at high temperatures, and the soap manufactured by the method It's about.

Natural soap is manufactured by adding oils and fats containing vegetable and animal oils, saponification reaction ingredients, and various extracts of active ingredients that are beneficial to the skin.

At this time, since oils and fats are vulnerable to rancidity, natural soap manufactured using such oils also has the problem of easily becoming rancid.

Pine tree is an evergreen coniferous tree, from which pine nuts and by-products, also called endosperm, can be obtained. By-products of the pine tree include wood stems, branches, pine needles (needle leaves), and the fruit, pine pine. Pine pine includes the hard outer bark, the outer bark, and the thin inner bark, the inner bark.

Pine nut extracts extracted from these pine trees include essential oil and pine nut oil.

Among these, pine nut oil is extracted from the endosperm of pine nuts and is characterized as a light yellow liquid, with pine nuts produced as a by-product. Conventional pine nut oil can be extracted by methods such as compression or solvent extraction, and is mainly extracted by compression.

However, pine nut oil extracted by the conventional pressing method has poor rancidity stability and color change characteristics, so there is a problem that rancidity or discoloration easily occurs. This pine nut oil is mainly used only as cooking oil, and development for other uses is necessary.

Additionally, pine nut essential oil is extracted from pine pine or pine leaves, which are discarded as by-products when harvesting pine nut endosperm, and is characterized as an oily and transparent liquid.

Conventional pine nut essential oil can be extracted by one of the following methods: steam distillation, water steam distillation, and solvent extraction.

Comparing the phytoncide components of pine nut oil using steam distillation and water-steam distillation, the phytoncide oil production yield of the water-steam distillation method is lower than that of the water-steam distillation method. Therefore, conventionally, the steam distillation method is mainly used when producing pine nut essential oil, which is a phytoncide oil, where the production yield is relatively higher than the water-steam distillation method.

Referring to Figure 1, the method of extracting pine nut essential oil by steam distillation is explained. First, pine pine pine needles and pine needles are put into a still, and steam is supplied from the bottom to distill, and the mixed vapor of steam and essential oil passes through the condenser, cools, and is sent to the separator. It is moved and separated in a separator into a transparent upper layer of oil-based pine essential oil containing oil-based phytoncides and a transparent lower layer of pine tree water containing water-soluble phytoncides.

Here, phytoncide is an antibacterial substance that plants release to protect themselves and includes phenol [mainly terpene (C ₅ H ₈ )n], alkaloid, glycoside, etc. In particular, pine nut phytoncide has antibacterial and skin soothing effects. have

However, phytoncide extracted using the conventional steam distillation method is highly volatile, so there is a problem that the antibacterial and skin soothing effects are short-term.

When applying this steam distillation method, the main components of pine nut oil are confirmed to be α-pinene, β-pinene, D-limonene, β-myrcene, and 3-carene, as shown in Table 1, and the contents of the components vary depending on the material. may vary.

In addition, when applying the steam distillation method, the aqueous phytoncide components of pine tree water are shown in Table 2 below, and there is a significant difference in composition from pine nut essential oil. Due to these differences in ingredients, pine nut oil and pine water have differences in performance and efficacy.

However, since the miscibility of pine nut oil and pine nut water is very low, separation is possible, but mixing requires processing and manipulation using separate surfactants, making it difficult to use them together.

Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings. However, the embodiments of the present invention may be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below.

In addition, 'including' a certain element throughout the specification means that other elements may be further included rather than excluding other elements, unless specifically stated to the contrary.

In the present invention, pine pine pine needles and pine needles are extracted with a fluid in a supercritical state to prepare a pine nut solution, and then oils and fats, pine nut solution, and saponification reaction components are mixed and a saponification reaction is performed to produce soap.

More specifically, the saponification reaction is carried out by mixing fats and oils composed of vegetable oil and animal oil, pine nut concentrate extracted from pine pine pine and pine needles with a fluid in a supercritical state, and saponification reaction components. .

Here, the saponification reaction can be carried out according to the chemical reaction formula below.

R-COO-R' (fatty acid of vegetable oil or animal fat) + MOH (M is Na, for example) → R-COO-M+ (soap) + R'OH (alcohol) mixture has residual base removed by saponification reaction. It reacts with fat and becomes hard, and can then be manufactured into solidified soap by putting it in a mold and maturing it for a predetermined period of time to saponify it.

The saponification reaction component may be purified water or strongly alkaline sodium hydroxide (NaOH), and may be included in 25 to 35% by weight of the total soap, and is an essential ingredient in the production of soap used in the saponification reaction of fats and oils. Sodium hydroxide (NaOH) is used to produce soap by participating in the saponification reaction.

In the present invention, the pine nut solution can be prepared using supercritical fluid extraction.

Figure 2 is a process diagram showing the supercritical fluid extraction method used in the present invention.

Referring to FIG. 2, in the supercritical fluid extraction method of one embodiment, washed pine cones and pine needles are placed in an extractor, and the fluid used at this time is CO ₂ , which pumps liquefied CO ₂ from a tank and compresses it to a pressure of 100 bar or more. The CO ₂ is heated to a temperature above 31°C using a heater to become supercritical and then supplied to the extractor.

Next, when the supercritical fluid is extracted from the extractor for 420 to 540 minutes, the CO ₂ fluid in a supercritical state acts as a solvent, allowing the CO ₂ to move to the separator carrying the phytoncide component from the pine pine pine and pine leaves.

At this time, when CO ₂ is decompressed during the process of moving to the separator, CO ₂ is transported as gas and separated, and only the pine nut solution containing phytoncide is moved to the separator and extracted. CO ₂ separated into gas goes through a cooler and is stored in a tank for reuse.

The pine nut concentrate prepared by this method, unlike pine oil and pine water, which are difficult to mix with each other by applying the conventional steam distillation method, contains oil-based phytoncide and water-based phytoncide, as well as chlorophyll and wax, etc. evenly mixed inside.

In addition, since the pine nut solution does not use high heat during the extraction process, the phytoncide component is not thermally decomposed or destroyed, and no solvent (CO ₂ ) remains after extraction and is not toxic, so it can be harmless to the human body.

Using this supercritical fluid extraction method to extract raw pine nuts at a pressure of 300 bar and 31 to 55°C, a phytoncide extraction rate of up to 5.3% can be obtained, which is superior to the conventional steam distillation method of about 1.9%, resulting in a higher yield. This is high.

Furthermore, as in one embodiment, when CO ₂ flows out as a supercritical fluid in a supercritical state at a pressure of 300 bar and a temperature of 31 to 40° C., sustained-release phytoncides (e.g., terpenes, terpenoids, etc.) with high molecular weight and low volatility are produced. ) It is possible to obtain the green solid pine nut solution of Figure 3, which has a higher content of pine nuts.

This pine nut solution may be included in 1.5 to 2.5% by weight of the total soap, and preferably 2% by weight of the total soap.

Furthermore, after preparing the pine nut solution in the same manner as above, the prepared pine nut solution can be melted by double boiling and then mixed with pine nut oil and stirred to prepare a pine nut solution dispersed in the pine nut oil. The pine nut solution dispersed in pine nut oil has increased sustained release compared to the pine nut solution without the pine nut oil acting as a film. Accordingly, phytoncide is contained for a longer period of time, allowing the antibacterial and skin soothing effects of the soap to last longer.

At this time, the pine nut solution can be double boiled at a temperature of 55°C or lower. If the temperature during double boiling of pine nut solution is too high, phytoncide volatilizes. Therefore, it is preferable to melt the pine nut solution by double boiling at a temperature of 55°C or lower as this can minimize volatilization and loss of phytoncide.

In addition, as the pine nut oil mixed with the pine nut solution, it is preferable to use pine nut oil obtained by extracting pine nut endosperm with a supercritical fluid, as described later, because it has excellent rancidity stability and color stability.

In the present invention, fat may be included in 60 to 70% by weight of the total soap, and may include coconut palm oil, olive oil, castor seed oil, sunflower oil, shea butter, cacao seed butter, grape seed oil, and palm oil that provide good effects on the skin. and argan oil, etc. may be included.

In addition, the oil may include pine nut oil as shown in Figure 4, which is obtained by extracting pine nut endosperm with a fluid in a supercritical state.

At this time, the oil can be composed only of pine nut oil extracted with supercritical fluid, excluding all other vegetable oils or animal oils. However, since pine nut oil is expensive, the critical value that can exhibit the unique performance and effects of pine nut oil is the critical value of the entire soap. It is desirable to include more than 5% by weight.

This pine nut oil does not use high heat during the extraction process, so its unique ingredients are not thermally decomposed or destroyed, and since no solvent (CO ₂ ) is left behind, it is non-toxic and harmless to the human body.

In addition, as shown in Table 3, pine nut oil prepared by the supercritical fluid extraction method has superior oxidation stability at room temperature compared to pine nut oil extracted by the conventional heat compression method, and can be used at high temperatures, such as when using hot water or hot water. The stability of color change is greatly improved, which can have the effect of preventing or delaying rancidity and discoloration of natural soap.

And, the soap according to one embodiment may further include pine nut flakes (powder).

As shown in Figure 5, the pine nut cake according to the present invention is a powder obtained by finely pulverizing the residue remaining after extracting pine nut oil from pine nut fermentation using a supercritical fluid extraction method. The antioxidant effect (electronic Donation ability, DPPH Free radical scav.) performance is up to 21.23% in water solvent conditions and 14.79% in ethanol solvent conditions, so it has a greater antioxidant effect than perilla meal, which shows 13.53 to 20%, and this pine nuts prevents the rancidity of natural soap. It can improve the action of preventing or delaying.

At this time, the pine nut oil can be more preferably subjected to a roasting process to remove the oil, and then subjected to secondary extraction with a supercritical fluid to obtain pine nut oil, and the remaining residue can be used. Using more defatted pine nuts can further improve the anti-rancidity and delay effects of natural soap.

Soap according to one embodiment may contain 0.5 to 1.5% by weight of the total pine nut soap, and preferably 1% by weight of the total soap.

If the content of pine nuts is less than 0.5% by weight, the effect of improving rancidity stability and color change characteristics cannot be properly implemented, and even if the content of pine nuts exceeds 1.5% by weight, the effect is not significantly increased.'

In addition, the soap according to one embodiment may include Houttuynia cordata extract, centella asiatica extract, sea grape extract, and sweet pumpkin powder as additional ingredients. Houttuynia cordata extract has antibacterial and anti-inflammatory effects, and Centella asiatica extract has skin regeneration and anti-inflammatory effects.

Comparative Example 1 : Preparation of pine nut essential oil by steam extraction method

Pine pine pine and pine needles are put into a distiller and steam is supplied from the bottom to distill, and the mixed vapor is cooled as it passes through a condenser and moved to a separator, where a transparent upper layer of oil-based pine essential oil containing oil-based phytoncide is obtained.

Example 1 : Preparation of pine nut concentrate by supercritical fluid extraction method (100 bar, 35℃)

Washed pine pine pine pine pine needles and pine needles are placed in an extractor, and supercritical CO ₂ at 100 bar and 35°C is added to the extractor, extracted for 8 hours, and the pressure is reduced to obtain a colorless liquid pine nut solution with a pine scent from the separator.

Example 2 : Preparation of pine nut concentrate by supercritical fluid extraction method (100 bar, 55℃)

The operation was the same as in Example 1, except that the supercritical state was changed to 100 bar and 55°C, and a colorless liquid with an off-odor was obtained from the separator.

Example 3 : Preparation of pine nut concentrate by supercritical fluid extraction method (300 bar, 35℃)

The operation was performed in the same manner as in Example 1, except that the supercritical state was changed to 300 bar and 35°C, and a dark green solid pine nut solution with a weak pine scent was obtained from the separator.

Example 4 : Preparation of pine nut concentrate by supercritical fluid extraction method (300 bar, 55℃)

The operation was the same as in Example 1, except that the supercritical state was changed to 300 bar and 55°C, and a green solid pine nut solution with a strong unpleasant odor was obtained from the separator.

Table 4 is a table comparing the characteristics of pine nut essential oil obtained by the steam extraction method of Comparative Example 1 and the pine nut solution obtained by the supercritical extraction method of Examples 1 to 4.

Looking at Table 4, the yields of Examples 1 to 4 using the supercritical fluid extraction method (2.8 to 5.3%), especially Examples 3 and 5, are higher than the yields of Comparative Example 1 using the steam extraction method (about 1.9%). You can tell it’s excellent.

In the case of Examples 1 and 2, where the pressure is 100 bar, the CO ₂ dissolving power is low, so the yield is low and a liquid pine nut solution is obtained. On the other hand, in Examples 3 and 4, where the pressure is 300 bar, the CO ₂ dissolving power is high, so the yield is high and green It can be seen that a solid pine nut solution was obtained.

In Examples 2 and 4, where the temperature is 55°C, the content of Mono C10 terpenoid, which has a small molecular weight and is highly volatile, increases, while in Examples 1 and 3, where the temperature is 35°C, the content of Sesqui C15, which has a large molecular weight and is weakly volatile, increases. It can be seen that the content of terpenoids and other terpenes increases.

In particular, in the case of Example 2 using the supercritical extraction method at 100 bar and 55°C, the yield is low, and the content of Mono C10 is higher than that of the steam extraction method, so it can be said that the sustained release of phytoncide is improved more than that of Comparative Example 1 of the steam extraction method. I can't.

On the other hand, in Example 3, which was performed by supercritical extraction at 300 bar and 35°C, the yield (5.0%) was excellent, and the content of highly volatile Mono C10 (61.4%) was low, but the content of oxygenated terpenoids (3.4%) was high, producing a fragrant aroma. Sesqui C15 is of excellent quality and contains 18% and 17.2% of less volatile terpenoids and other terpenes, respectively, so you can obtain a sustained-release pine nut solution that slowly releases phytoncide. According to repeated experiments, equivalent results can be obtained in the range of 300 bar 31 to 40°C.

Therefore, in the present invention, a high-yield, high-quality pine nut solution extracted with a carbon dioxide fluid in a supercritical state of 300 bar and 31 to 40° C. is preferably used.

Example 5 : Preparation of pine nut oil and pine nut meal by supercritical fluid extraction method (300 bar, 35℃)

The pine endosperm (nut) with the outer and inner coats peeled and washed is placed in the extractor, supercritical CO ₂ at 300 bar and 35°C is added to the extractor, extracted for 8 hours, and then the pressure is reduced to extract the yellow liquid pine nut oil and its seeds from the separator. Pine nut powder is obtained as a by-product.

Example 6 : Preparation of pine nut concentrate dispersed in pine nut oil

The green solid pine nut solution prepared in Example 3 was slowly melted by boiling in water at a temperature of 55°C or lower, and then added to the pine nut oil prepared in Example 5 and mixed to prepare a pine nut solution dispersed in pine nut oil.

Example 7 : Preparation of degreased pine nuts extracted from secondary supercritical fluid after distribution

The pine nut powder obtained as a by-product in Example 5 was roasted in a frying pan to leak the pine nut oil, and then put back into the extractor of the supercritical fluid extraction device, and the pine nut oil was obtained through secondary supercritical fluid extraction in the same process as in Example 5. As a by-product, defatted pine nut powder is prepared.

Add more purified water and sodium hydroxide and continue stirring in a stirrer to complete the saponification reaction. Once the saponification reaction is complete, pour it into a 20kg unit drying box and first naturally dry it in a drying room. Once it has dried hard enough to be cut, cut the soap into pieces 30cm long and 3cm wide using a piano wire cutter.

Place the cut soaps on a tray and move them to a drying room with a humidity of 35% or less for secondary drying. Cut in 100g units and move to a drying room with humidity below 30% for third drying. After molding the soap into the mold shape using a press, it is dried for 5 weeks in a drying room with a humidity of 30% or less to produce green pine nut soap as shown in Figure 6.
